These components have been designed for your specific project requirements and job location. Reading and understanding all information included in this package prior to installation is important to help insure a successful and safe project. Contact your BFS representative if you have further questions or if you need further information. Notes: Notes: Notes: Notes: 1. The sole responsibility of BFS is to design and supply individual trusses and components to the dimensions and design criteria provided to BFS by the customer. The design of the remaining portions of the building is the responsibility of the building designer, engineer of record, or the customer / contractor in the absence of a design professional. 2. The design and specification of the permanent and temporary bracing is the responsibility of the building designer per TPI-1 as referenced in the building code. The bracing documents we provide are the general minimum standards and should be verified or adapted by others as necessary for the specific project. 3. All wood component products supplied by BFS shall be used in dry service applications (Moisture Content<19%) unless noted otherwise. 4. The plies of multi-ply trusses are to be attached together by the installer per the fastener schedule on the specific truss drawing. 5. The building designer, engineer of record, or customer shall resolve any issues or connections between trusses and other structural members not provided or specified by BFS when needed. 6. Truss placement plans and truss drawings are the property of BFS and may not be used or reproduced without the written approval of BFS. Products remain property of BFS until paid in full. 7. Install trusses per the BFS placement plan, industry standards, and code requirements. Install recommended floor truss strongbacks at 10' o.c. Do not install trusses upside down. Avoid conflicts with plumbing & other trades. 8. Truss drawings indicate standard loads and added loads in the load cases section. Do not apply structural loads to any truss if that load is not shown on the truss drawing. Verify stick framed roof loads transfer where allowed & designed for. Erection and Bracing: Erection and Bracing: Erection and Bracing: Erection and Bracing: The customer accepts full responsibility for the handling, storage, erection, installation, and bracing of these components and shall supervise any subcontractor or other party that is carrying out this work. We have included industry standard erection, temporary bracing, and fall protection information as a minimum guideline. However, D1_BFS.docx 2017-01-02 BFS is not responsible for ensuring that these minimum guidelines are enforced and that they are applicable to the project. Please note that short members, such as 22-1/2” 2x4’s, connecting 2 trusses do not count as bracing. Stability:Stability:Stability:Stability: Until the building is completely built and sheathed in accordance with the project plans by the building designer / engineer of record and meets code and local requirements, it may be unstable and present a safety hazard unless properly braced. The builder / framer shall build and properly brace the structure by floor - do not build additional stories of construction on a poorly braced structure below. Instability may increase with building dimensions - particularly height. Winds: Winds: Winds: Winds: Buildings under construction may be vulnerable to high winds. The builder and framer shall consider all weather conditions including the potential for winds when deciding to set trusses. If high winds are expected, truss erection should be postponed or a consulting engineer should specify additional temporary bracing required to meet the possible conditions. Issues:Issues:Issues:Issues: If you encounter any jobsite installation issues that appear to involve the modification of the truss or component, please contact your BFS representative immediately. The representative will determine the nature of the issue and help facilitate its remedy. Do not make alterations or repairs prior to receiving repair details or instructions from BFS. If the issue is manufacturing related, BFS reserves the right to repair or replace the component in question. If the component in question is not structurally stable, install additional shoring to insure project safety. Charge Backs:Charge Backs:Charge Backs:Charge Backs: Charge backs will not be accepted unless agreed upon by an authorized BFS representative prior to the repair or modification in question. It is the responsibility of the contractor to inform BFS of any error, problem, or defect prior to or during setting of the components. In the event of a charge back, an authorization number will be given by BFS for an agreed upon specific amount to resolve the issue. This authorization number must accompany any charge back to BFS to be valid.

JOBSITE PACKAGE IMPORTANT DOCUMENTS ENCLOSED PLEASE REVIEW FOR DESIGN RESPONSIBILITIES SEE REVERSE WARNING The handling, storing, installing, restraining and diagonal bracing of structural building com- ponents requires specialized training, clearly implemented procedures, and careful planning and communication among the contractor, crane operator and installation crew. Handling and installing components without appropriate training, planning and communication greatly increases the probability of an accident resulting in property damage, serious personal injury and/or death. Prior to component installation, the documents should be examined and disseminated to all appropriate personnel, in addition to proper training and a clear understanding of the installation plan, any applicable fall protection requirements, and the intended restraint and bracing requirements. Trusses with clear spans of 60 feet or greater in length are very dangerous to install and may require complex temporary and permanent bracing. Please consult a Registered Design Professional. Examine the building, the building’s structural framing system, bearing locations and related installation conditions. Begin com-ponent installation only after any unsatisfactory conditions have been corrected. Do not cut, modify or repair components. Report any damage before installation. The enclosed documents are offered as minimum guidelines only. Nothing contained in this jobsite package should be construed in any manner as expanding the scope of responsibility of, or imposing any additional liabilities on, the component manufacturer.¡ADVERTENCIA!

Diagonal BracingLateral Restraint Structural Sheathing Construction Loading DO's and DON’Ts DON’T stack materials on unbraced trusses. DON’T overload the trusses. DON’T exceed stack heights listed in the table below. Construction loads are those loads imposed on the unfinished building as a result of the construction process. Typical construction loads in-clude the weight of the work-ers, equipment, and building materials, to name a few. For example, a bundle of plywood sheathing or gypsum board stacked on trusses temporar-ily creates construction loads. þ Make sure that the truss assembly is properly restrained and braced according to the guidelines in BCSI-B1*** and BCSI-B2*** before placing any construction loads on them. Construction loads shall only be placed on fully restrained and braced structures. WARNING Stacking excessive amounts of construction materials on floor or roof trusses is an unsafe practice. Prop-erty damage, personal injury and/or death are possible if this warning is not heeded. Trusses that have been over-stressed due to excessive construction loading will usually show excessive sagging (deflec-tion) and at least a portion of this deflection will remain even after the load has been removed. In more severe cases, broken truss members and/or failed truss joints may result.

Cargas de construcción típicas incluyen el peso de los trabajadores, el equipo y los materiales de construcción, etcétera. Por ejemplo, un paquete de entablado contrachapado o tabla de yeso apila-dos temporalmente sobre los trusses crean cargas de construcción.þ Asegúrese que el montaje del truss está adecuadamente restringido y arriostrado según las pautas en BCSI-B1*** y BCSI-B2 *** antes de colocar alguna carga de construcción en la estructura. Solamente coloquen cargas de construcción arriba de estructuras cuales son restringidos y arriostrados completamente.¡ADVERTENCIA! Apilando cantidades excesivas de cargas de construcción sobre trusses de piso u techo es una práctica peligrosa. Daño a la propiedad, herida personal y/o muerte son posibles si no sigue esta advertencia. Los trusses que han sidos demasiado estresados de-bido a cargas de construcción excesivas usualmente demuestran una desviación excesiva, y por lo menos una parte de este desviación se quedarán aún después de que la carga se haya quitada. En casos más severos, miembros quebrados del truss y/o junturas falladas pueden resultar. 1 This table is based on trusses designed with a live load of 40 psf or greater.

BCSI-B4 SUMMARY SHEET Fall Protection & Trusses Protección de Caída y TrussesB11 Regulations on fall protection and erection/installation of trusses in residential construction are contained in OSHA’s Fall Protec-tion Standard, 29 CFR 1926 Subpart M(the Standard). Section 1926.501(b)(13) of the Standard states in part: “Each employee engaged in residential construction activities 6 feet or more above lower levels shall be protected by guardrail systems, scaf-folding, a safety net system or a personal fall arrest system.” Las regulaciones sobre protección contra caídas y levantamiento/instalación de entramados en construcción residencial vienen contenidos en la Regulación de Protección contra Caídas de OSHA, 29 CFR 1926 Subparte M (el Estándar). La sección 1926.501(b)(13) de la regulación establece en parte: “Cada empleado que participe en actividades de construcción residencial a 6 pies o más por encima de niveles inferiores deberán estar protegidos por sistemas de rampas de protección, andamiaje, un sistema de red de seguridad o un sistema de protección personal para detención de caídas.” DANGER Any part of an inad-equately braced or sheathed roof or floor truss system used as an anchorage point for any type of personal fall arrest system is dangerous and will increase the risk of serious injury or death. WARNING Roof and floor trusses that are not properly braced per BCSI or sheathed are not able to resist lateral impact loads associated with falls. A falling worker attached to an inadequately braced set of trusses could cause all the previously set trusses to col-lapse in a domino effect. Refer to BCSI-B1* and BCSI-B2 for recommendations on proper bracing of trusses. Consulte BCSI-B1* sobre recomendaciones para levantar correcto de los entramados. ¡PELIGRO! No camine sobre entramados no apuntalados. ¡PELIGRO! No se pare en el braguero voladizos hasta revestimiento estructural se ha aplicado a la armadura y voladizos. B11Fall 150722 SBCA has created an alternate fall protection plan template, complete with links throughout the document to the applicable steps to follow in its online step-by-step approach to erecting an initial truss system under OSHA’s fall protection requirements. Visit sbcindustry.com/fp Truss Systems Sistemas de Entramama¡PELIGRO! Cualquier pieza de un sistema de entramado de techo o el piso apuntalado o forrado de forma inadecua-da que se utilice como punto de anclaje para cualquier tipo de sistema de protec-ción personal para detención de caídas es peligroso y aumentará el riesgo de lesiones personales de gravedad o la muerte. ¡ADVERTENCIA! Los entramados de techo y piso que no están correctamente apuntalados según BCSI o forrados no pueden resistir cargas de impacto lateral asociadas con caídas. Un trabajador que sufra una caída y que esté acoplado a un conjunto de entramados que no estén apuntalados adecuadamente podría pro-vocar que los entramados fijados previa-mente se colapsen con un efecto dominó.  Refer to BCSI-B1* for recom-mendations on proper hoisting of trusses. DANGER Do not walk on unbraced trusses. DANGER Do not stand on Truss over-hangs until Structural Sheathing has been applied to the Truss and overhangs.

Restraint/Bracing Materials & Fasteners Materiales y Cierres de Restricción/Arriostre Commonly used restraint/bracing materials include wood structural panels, gypsum board sheathing, stress-graded lumber, proprietary metal products, and metal purlins and straps. Materiales comunes de arriostrar/ restringir incluyen paneles estructurales de madera, entablado e yeso, madera graduada por esfuerza, productos de metal patentados, y vigas de soporte y tiras de metal. Permanent Bracing for the Various Planes of a Truss Arriostre Permanente para Varios Planos de un Truss Permanent bracing is important because it, a) prevents out-of-plane buckling of truss members, b) helps maintain proper truss spacing, and c) resists and transfers lateral loads from wind and seismic forces. El arriostre permanente es importante porque, a) impide el torcer fuera-de-plano de los miem-bros del truss, b) ayuda en mantener espaciamiento apropiado de los trusses, y c) resiste y pasa las cargas laterales de viento y fuerzas sísmicas aplicadas al sistema del truss. Trusses require permanent bracing within ALL of the following planes: 1. Top chord plane 2. Bottom chord plane 3. Web member plane CAUTION The truss, or a portion of its members, will buckle (i.e., fail) at loads far less than design without permanent bracing. ¡CAUTELA! Sin el arriostre permanente, del truss, o un parte de los miembros, torcerán (ej. fallarán) de cargas muchas menos que las cargas que el truss es diseñado a llevar.  Use plywood, oriented strand board (OSB), or wood or metal structural purlins that are properly braced. Attach to each truss. Use contrachapado, panel de fibras orientado (OSB), o vigas de soporte de madera o metal que estén arriostrados apropiadamente. Sujete a cada truss. The Truss Design Drawing (TDD) provides information on the assumed support for the top chord.

Web Member Plane Permanent Building Stability Bracing to Transfer Wind & Seismic Forces Arriostre de Estabilidad Permanente del Edificio del Plano de Miembros Secundarios para Desplazar Fuerzas de Viento y Fuerzas Sísmicas The web member restraint or reinforcement specified on a TDD is required to resist buckling due to axial forces caused by the in-plane loads applied to the truss. Additional restraint and bracing within the web member plane may also be required to transfer lateral forces due to wind and/or seismic loads applied perpendicular to the plane of the trusses. This restraint and bracing is typically speci-fied by the building designer. La restricción o refuerzo de miembros secundarios especificada en un TDD es requerido para resistir la deformación bajo fuerzas axiales causadas por cargas verticales aplicadas al truss. Re-stricción adicional y el aparato ortopédico dentro del plano miembro de banda también puede ser necesaria para transferir fuerzas laterales debidas al viento y / o cargas sísmicas aplicadas perpen-dicular al plano de las cerchas. Esta restricción y arriostre es típicamente provisto por el diseñador del edificio.  Some truss designers provide general design tables and details to assist the building designer in determining the bracing required to transfer lateral loads due to wind and/or seismic forces from the gable end frame into the roof and/or ceiling diaphragm. Algunos diseñadores de trusses proveen tablas y detalles de diseño generales para asistir el diseñador del edificio en determinar el arriostre requerido para pasar cargas laterales debidas a fuerzas de viento y/o fuerzas sísmicas del armazón hastial al diafragma del techo. Gable End Frames and Sloped Bottom ChordsArmazones Hastiales Y Cuerdas Inferiores Pendientes The gable end frame should always match the profile of the adjacent trusses to ensure the top of the end wall aligns with, and can be braced by, the celing diaphragm. El armazón hastial siempre debe encajar el perfil de los trusses contiguous para permitir la insta-lación de restricción y arriostre apropiada de la cuerda inferior a menos que arriostre especial es diseñado para soportar la pared de extremo. CAUTION Using a flat bottom chord gable end frame with adjacent trusses that have sloped bot-tom chords is prohibited by some building codes as adequate bracing of this condition is difficult and sometimes impossible. Special end wall bracing design considerations are required by the building designer if the gable end frame profile does not match the adjacent trusses. ¡CAUTELA! El uso de un armazón hastial de la cuerda inferior con trusses contiguos cuales tienen cuerdas inferiores pendientes es prohibido por algunos códigos de edificios porque ar-riostre adecuado de esta condición es difícil y a veces imposible. Consideraciones especiales de diseño para el arriostre de la pared de extremo son requeridos por el diseñador del edificio si el perfil del armazón hastial no hace juego con los trusses contiguos.Permanent Bracing for Special ConditionsArriostre Permanente Para Condiciones Especiales Sway Bracing—Arriostre de “Sway”  Some truss manufacturers provide additional assistance by using tags to mark the web members that require lateral restraint or reinforcement. Algunos fabricantes de trusses marcan en el truss las ubicaciones de refuerzo o restricción lateral de miembros secundarios con etiquetas similares a las arriba.

El resultado de un manejo, levanta-miento, instalación, restricción y arrisotre incorrecto puede ser la caída de la estructura o aún peor, heridos o muertos. CAUTION Exercise care when remov-ing banding and handling trusses to avoid damaging trusses and prevent injury. Wear personal protective equipment for the eyes, feet, hands and head when working with trusses. ¡CAUTELA! Utilice cautela al quitar las ataduras o los pedazos de metal de sujetar para evitar daño a los trusses y prevenir la herida personal. Lleve el equipo protectivo personal para ojos, pies, manos y cabeza cuando trabaja con trusses. Avoid lateral bending. Evite la flexión lateral. The contractor is responsible for properly receiving, unloading and storing the trusses at the jobsite. Unload trusses to smooth surface to prevent damage. El contratista tiene la responsabilidad de recibir, descargar y almacenar adecuadamente los trusses en la obra. Descargue los trusses en la tierra liso para prevenir el daño.  Trusses may be unloaded directly on the ground at the time of delivery or stored temporarily in contact with the ground after delivery. If trusses are to be stored for more than one week, place blocking of sufficient height beneath the stack of trusses at 8’ (2.4 m) to 10’ (3 m) on-center (o.c.). Los trusses pueden ser descargados directa-mente en el suelo en aquel momento de entrega o almacenados temporalmente en contacto con el suelo después de entrega. Si los trusses estarán guardados para más de una semana, ponga bloqueando de altura suficiente detrás de la pila de los trusses a 8 hasta 10 pies en centro (o.c.). If trusses are to be stored for more than one week, cover bundles to protect from the environment. Para trusses guardados por más de una semana, cubra los paquetes para protegerlos del ambiente. Refer to BCSI*** for more detailed information per-taining to handling and jobsite storage of trusses. Vea el folleto BCSI*** para información más detal-lada sobre el manejo y almacenado de los trusses en área de trabajo.  Use proper rig- ging and hoisting equipment.

This document may not be reproduced in any form without the written permission of the publishers and should appear in more than one color. Printed in the United States of America. Standard JOBSITE PACKAGE shown Properly restrain and brace trusses before stacking construction materials on them.Diagonal BracingLateral Restraint Structural Sheathing Construction Loading DO's and DON’Ts DON’T stack materials on unbraced trusses. DON’T overload the trusses. DON’T exceed stack heights listed in the table. Construction loads are those loads imposed on the unfinished building as a result of the construction process. Typical construction loads in-clude the weight of the work-ers, equipment, and building materials, to name a few. For example, a bundle of plywood sheathing or gypsum board stacked on trusses temporar-ily creates construction loads. þ Make sure that the truss assembly is properly restrained and braced according to the guidelines in BCSI-B1*** and BCSI-B2*** before placing any construction loads on them. Construction loads shall only be placed on fully restrained and braced structures. WARNING Stacking excessive amounts of construction materials on floor or roof trusses is an unsafe practice. Prop-erty damage, personal injury and/or death are possible if this warning is not heeded. Trusses that have been over-stressed due to excessive construction loading will usually show excessive sagging (deflec-tion) and at least a portion of this deflection will remain even after the load has been removed. In more severe cases, broken truss members and/or failed truss joints may result.

Cargas de construcción típicas incluyen el peso de los trabajadores, el equipo y los materiales de construcción, etcétera. Por ejemplo, un paquete de entablado contrachapado o tabla de yeso apila-dos temporalmente sobre los trusses crean cargas de construcción.þ Asegúrese que el montaje del truss está adecuadamente restringido y arriostrado según las pautas en BCSI-B1*** y BCSI-B2 *** antes de colocar alguna carga de construcción en la estructura. Solamente coloquen cargas de construcción arriba de estructuras cuales son restringidos y arriostrados completamente.¡ADVERTENCIA! Apilando cantidades excesivas de cargas de construcción sobre trusses de piso u techo es una práctica peligrosa. Daño a la propiedad, herida personal y/o muerte son posibles si no sigue esta advertencia. Los trusses que han sidos demasiado estresados de-bido a cargas de construcción excesivas usualmente demuestran una desviación excesiva, y por lo menos una parte de este desviación se quedarán aún después de que la carga se haya quitada. En casos más severos, miembros quebrados del truss y/o junturas falladas pueden resultar. 1 This table is based on trusses designed with a live load of 40 psf or greater.

BCSI-B4 SUMMARY SHEET2016 B4 Summary Sheet.indd 1 2/17/2016 12:16:42 PM Fall Protection & Trusses Protección de Caída y TrussesB11Regulations on fall protection and erection/installation of trusses in residential construction are contained in OSHA’s Fall Protec-tion Standard, 29 CFR 1926 Subpart M(the Standard). Section 1926.501(b)(13) of the Standard states in part: “Each employee engaged in residential construction activities 6 feet or more above lower levels shall be protected by guardrail systems, scaf-folding, a safety net system or a personal fall arrest system.”Las regulaciones sobre protección contra caídas y levantamiento/instalación de entramados en construcción residencial vienen contenidos en la Regulación de Protección contra Caídas de OSHA, 29 CFR 1926 Subparte M (el Estándar). La sección 1926.501(b)(13) de la regulación establece en parte: “Cada empleado que participe en actividades de construcción residencial a 6 pies o más por encima de niveles inferiores deberán estar protegidos por sistemas de rampas de protección, andamiaje, un sistema de red de seguridad o un sistema de protección personal para detención de caídas.” DANGER Any part of an inad-equately braced or sheathed roof or floor truss system used as an anchorage point for any type of personal fall arrest system is dangerous and will increase the risk of serious injury or death. WARNING Roof and floor trusses that are not properly braced per BCSI or sheathed are not able to resist lateral impact loads associated with falls. A falling worker attached to an inadequately braced set of trusses could cause all the previously set trusses to col-lapse in a domino effect.þ Refer to BCSI-B1* and BCSI-B2 for recommendations on proper bracing of trusses.

WARNING Disregarding permanent restraint/bracing is a major cause of truss field performance problems and has been known to lead to roof or floor system collapse. ¡ADVERTENCIA! Descuidar el arriostre/restricción permanente es una causa principal de prob-lemas de rendimiento del truss en campo y había conocido a llevar al derrumbamiento del sistema del techo o piso. CAUTION! Trusses with clear spans of 60 feet (18.3 m) or greater, may require complex perma-nent bracing. Please always consult a registered design professional. ¡CAUTELA! Tramos sobre 60 pies o más pueden requerir arriostre permanente complejo. Por favor, consulte siempre a un profesional registrado de diseño. Restraint/Bracing Materials & Fastener Materiales y Cierres de Restricción/Arriostreþ Commonly used restraint/bracing materials include wood structural panels, gypsum board sheathing, stress-graded lumber, proprietary metal products, and metal purlins and straps. Materiales comunes de arriostrar/restringir incluyen paneles estructurales de madera, entablado de yeso, madera graduada por esfuerza, productos de metal patentados, y vigas de soporte y tiras de metal. Permanent Bracing for the Various Planes of a Truss Arriostre Permanente para Varios Planos de un Trussþ Permanent bracing is important because it, a) prevents out-of-plane buckling of truss members, b) helps maintain proper truss spacing, and c) resists and transfers lateral loads from wind and seismic forces. El arriostre permanente es importante porque, a) impide el torcer fuera-de-plano de los miem-bros del truss, b) ayuda en mantener espaciamiento apropiado de los trusses, y c) resiste y pasa las cargas laterales de viento y fuerzas sísmicas aplicadas al sistema del truss.þ Trusses require permanent bracing within ALL of the following planes: 1. Top chord plane 2. Bottom chord plane 3. Web member plane cauTIon Without permanent bracing the truss, or a portion of its members, will buckle (i.e., fail) at loads far less than design. ¡CAUTELA! Sin el arriostre permanente, del truss, o un parte de los miembros, torcerán (ej. fallarán) de cargas muchas menos que las cargas que el truss es diseñado a llevar.þ Use plywood, oriented strand board (OSB), or wood or metal structural purlins that are properly braced. Attach to each truss. Use contrachapado, panel de fibras orientado (OSB), o vigas de soporte de madera o metal que estén arriostrados apropiadamente. Sujete a cada truss.þ The Truss Design Drawing (TDD) provides information on the assumed support for the top chord. El Dibujo del Diseño de Truss (TDD) provee información sobre el soporte supuesto para la cuerda superior.þ Fastener size and spacing requirements and grade for the sheathing, purlins and bracing are provided in the building code and/or by the build-ing designer. El tamaño de cierre y requisitos de espaciamien-to y grado para el entablado, vigas de soporte y arriostre son provistos en el código del edificio y/o por el diseñador del edificio.2. Permanent Bracing for the Bottom Chord Plane Arriostre Permanente para el Plano de la Cuerda Inferiorþ Use rows of continuous lateral restraint with diagonal bracing, gypsum board sheathing or some other ceiling material capable of functioning as a diaphragm. Use filas de restricción lateral continua con arriostre diagonal, entablado de yeso o cualquier otro material para techo que pueda funcionar como un diafragma. Trusses requieren arriostre permanente dentro de TODOS los siguientes planos: 1. Plano de la cuerda superior 2. Plano de la cuerda inferior 3. Plano del miembro secundario 1. Permanent Bracing for the Top Chord Plane Arriostre Permanente para el Plano de la Cuerda Superior þ The TDD provides information on the assumed support for the bottom chord. El TDD provee información sobre el soporte supuesto para la cuerda inferior.þ Install bottom chord permanent lateral restraint at the spacing indicated on the TDD and/or by the building designer with a maximum of 10’ (3 m) on-center. Instale restricción lateral permanente de la cuerda inferior al espaciamiento indicado en el TDD y/o por el diseñador del edificio con un máximo de 10 pies en el centro. 3. Permanent Bracing for the Web Member Plane Arriostre Permanente papa El Plano del Miembro Secundario Web member permanent bracing collects and transfers buckling restraint forces and/or lateral loads from wind and seismic forces. The same bracing can often be used for both functions. Arriostre permanente de los miembros secundarios recogen y pasan fuerzas de restricción de torcer y/o cargas laterales de viento y fuerzas sísmicas. A menudo el mismo arriostre puede ser usado para ambos funciones.Individual Web Member Permanent Restraint & BracingRestricción y Arriostre Permanente de Miembros Secundarios Individualesþ Check the TDD to determine which web members (if any) require restraint to resist buckling. Revisa el TDD para determinar cuales miembros secundarios (si algunos) requieren restricción para resistir el torcer.þ Restrain and brace with, A. Continuous lateral restraint & diagonal bracing, or B. Individual member web reinforcement. Restrinja y arriostre con, A. Restricción lateral continua y arriostre diagonal, o B. Refuerzo de miembros secundarios individuales. A. Continuous Lateral Restraint (CLR) & Diagonal Bracing Restricción Lateral Continua (CLR) y Arriostre Diagonalþ Attach each row of CLR at the locations shown on the TDD. Sujete cada fila de CLR en las ubicaciones mostrados en el TDD.þ Install the diagonal bracing at an angle of less-than-or-equal-to 45° to the CLR and position so that it crosses the web in close proximity to the CLR. Attach the diagonal brace as close to the top and bottom chords as possible and to each web it crosses. Repeat every 20’ (6.1 m) or less. Instale el arriostre diagonal a un ángulo menos de o igual a 45° al CLR y colóquelo para que cruce la cuerda muy cerca del CLR. Sujete el arriostre diagonal tan próximo a las cuerdas superiores y inferiores como sea posible y a cada cuerda que lo cruza. Repita cada 20 pies (6.1 m) o menos. þ Lateral restraint & diagonal bracing can also be used with small groups of trusses (i.e., three or less). Attach the lateral restraint & diagonal brace to each web member they cross. Restricción lateral y arriostre diagonal también puede ser usado con grupos pequeños de trusses (ej. tres o menos). Sujete la restricción lateral y el arriostre diagonal a cada miembro secundario que los cruzan. ALWAYS DIAGONALLY BRACE THE CONTINUOUS LATERAL RESTRAINT!¡SIEMPRE ARRIOSTRE LA RESTRICCIóN LATERAL CONTINUA DIAGONALMENTE! B. Individual Web Member Reinforcement Refuerzo de Miembros Secundarios Individuales T-, L-, Scab, I-, U-Reinforcement, proprietary metal reinforcement and stacked web products provide an alternative for resisting web buckling. T-, L-, costra, I-, U-Refuerzo, refuerzo de metal patentando y productos de miembros secundarios amontonados proveen una alternativa para resistir el torcer de los miembros secundarios. þ Some truss manufacturers provide additional assistance by using tags to mark the web members that require lateral restraint or reinforcement. Algunos fabricantes de trusses marcan en el truss las ubicaciones de refuerzo o restricción lateral de miembros secundarios con etiquetas similares a las arriba. Web Member Plane Permanent Building Stability Bracing to Transfer Wind & Seismic Forces Arriostre de Estabilidad Permanente del Edificio del Plano de Miembros Secundarios para Desplazar Fuerzas de Viento y Fuerzas Sísmicasþ The web member restraint or reinforcement specified on a TDD is required to resist buckling due to axial forces caused by the in-plane loads applied to the truss. Additional restraint and bracing within the web member plane may also be required to transfer lateral forces due to wind and/or seismic loads applied perpendicular to the plane of the trusses. This restraint and bracing is typically speci-fied by the building designer. La restricción o refuerzo de miembros secundarios especificada en un TDD es requerido para resistir la deformación bajo fuerzas axiales causadas por cargas verticales aplicadas al truss. Re-stricción adicional y el aparato ortopédico dentro del plano miembro de banda también puede ser necesaria para transferir fuerzas laterales debidas al viento y / o cargas sísmicas aplicadas perpen-dicular al plano de las cerchas. Esta restricción y arriostre es típicamente provisto por el diseñador del edificio. þ Some truss designers provide general design tables and details to assist the building designer in determining the bracing required to transfer lateral loads due to wind and/or seismic forces from the gable end frame into the roof and/or ceiling diaphragm. Algunos diseñadores de trusses proveen tablas y detalles de diseño generales para asistir el diseñador del edificio en determinar el arriostre requerido para pasar cargas laterales debidas a fuerzas de viento y/o fuerzas sísmicas del armazón hastial al diafragma del techo. Gable End Frames and Sloped Bottom ChordsArmazones Hastiales Y Cuerdas Inferiores Pendientesþ The gable end frame should always match the profile of the adjacent trusses to permit installation of proper bottom chord plane restraint & bracing unless special bracing is designed to support the end wall. El armazón hastial siempre debe encajar el perfil de los trusses contiguous para permitir la insta-lación de restricción y arriostre apropiada de la cuerda inferior a menos que arriostre especial es diseñado para soportar la pared de extremo. CAUTION! Using a flat bottom chord gable end frame with adjacent trusses that have sloped bottom chords is prohibited by some building codes as adequate bracing of this condition is dif-ficult and sometimes impossible. Special end wall bracing design considerations are required by the building designer if the gable end frame profile does not match the adjacent trusses. ¡CAUTELA! El uso de un armazón hastial de la cuerda inferior con trusses contiguos cuales tienen cuerdas inferiores pendientes es prohibido por algunos códigos de edificios porque ar-riostre adecuado de esta condición es difícil y a veces imposible. Consideraciones especiales de diseño para el arriostre de la pared de extremo son requeridos por el diseñador del edificio si el perfil del armazón hastial no hace juego con los trusses contiguos.Permanent Bracing for Special ConditionsArriostre Permanente Para Condiciones EspecialesSway Bracing—Arriostre de “Sway”BCSI-B1 SUMMARY SHEET - GUIDE FOR HANDLING, INSTALLING, RESTRAINING AND BRACING OF TRUSSESSpans over 60’ may require complex permanent bracing.

Construction loads shall only be placed on fully restrained and braced structures. Asegúrese que el montaje del truss está adecuadamente restringido y arriostrado según las pautas en BCSI-B1*** y BCSI-B2 *** antes de colocar alguna carga de construcción en la estructura. Solamente coloquen cargas de construcción arriba de estructuras cuales son restringidos y arriostrados completamente. WARNINg! Stacking excessive amounts of construction materials on floor or roof trusses is an unsafe practice. Prop-erty damage, personal injury and/or death are possible if this warning is not heeded. ¡AdVERTENCIA! Apilando cantidades excesivas de cargas de construcción sobre trusses de piso u techo es una prác-tica peligrosa. Daño a la propiedad, herida personal y/o muerte son posibles si no sigue esta advertencia. Trusses that have been over-stressed due to excessive construction loading will usually show excessive sagging (deflection) and at least a portion of this deflection will remain even after the load has been removed. In more severe cases, broken truss members and/or failed truss joints may result. Los trusses que han sidos demasiado estresados debido a cargas de construcción excesivas usualmente demuestran una desviación excesiva, y por lo menos una parte de este desviación se quedarán aún después de que la carga se haya quitada. En casos más severos, miembros quebrados del truss y/o junturas falladas pueden resultar. doN’T stack materials on unbraced trusses. No amontone materiales sobre trusses que no esten arriostrados. doN’T overload the trusses. No sobrecargue los trusses. doN’T exceed stack heights listed in the table.

Typical construction loads include the weight of the workers, equipment, and building materials, to name a few. For example, a bundle of plywood sheathing or gypsum board stacked on trusses temporarily creates construction loads.Cargas de construcción son las cargas que están impuestas a los edificios incompletos como resultado del proceso de construcción. Cargas de construcción típicas incluyen el peso de los trabajadores, el equipo y los materiales de construcción, etcétera. Por ejemplo, un paquete de entablado contrachapado o tabla de yeso apilados temporalmente sobre los trusses crean cargas de construcción. Note: Limit stacking periods to approximately one week, unless alternative information is provided by the Building Designer, Truss Designer or Truss Manufacturer.BCSI-B11 SUMMARY SHEET FALL PRoTECTIoN & TRUSSESFall Protection & Trusses Protección de Caída y TrussesB11Regulations on fall protection and erection/installation of trusses in residential construction are contained in OSHA’s Fall Protection Standard, 29 CFR 1926 Subpart M(the Standard). Section 1926.501(b)(13) of the Standard states in part: “Each employee engaged in residential construction activities 6 feet or more above lower levels shall be protected by guardrail systems, scaffolding, a safety net system or a personal fall arrest system.”Las regulaciones sobre protección contra caídas y levantamiento/instalación de entramados en construcción residencial vienen contenidos en la Regulación de Protección contra Caídas de OSHA, 29 CFR 1926 Subparte M (el Estándar). La sección 1926.501(b)(13) de la regulación establece en parte: “Cada empleado que participe en actividades de construcción residencial a 6 pies o más por encima de niveles inferiores deberán estar protegidos por sistemas de rampas de protección, andamiaje, un sistema de red de seguridad o un sistema de protección personal para detención de caídas.” DANGER Any part of an inadequately braced or sheathed truss system used as an anchor-age point for any type of personal fall arrest system is dangerous and will increase the risk of serious injury or death. ¡PELIGRO! Cualquier pieza de un sistema de entramado apuntalado o forrado de forma inadecuada que se utilice como punto de anclaje para cualquier tipo de sistema de protec-ción personal para detención de caídas es peligroso y aumentará el riesgo de lesiones personales de gravedad o la muerte. WARNING Trusses that are not properly braced per BCSI or sheathed are not able to resist lateral impact loads associated with falls. A falling worker attached to an inadequately braced set of trusses could cause all the previously set trusses to collapse in a domino effect. ¡ADVERTENCIA! Los entramados que no están correctamente apuntalados según BCSI o forrados no pueden resistir cargas de impacto lateral asociadas con caídas. Un trabajador que sufra una caída y que esté acoplado a un conjunto de entramados que no estén apuntalados adecuadamente podría provocar que los entra-mados fijados previamente se colapsen con un efecto dominó. DANGER Do not walk on unbraced trusses. ¡PELIGRO! No camine sobre entramados no apuntalados.B11Fall 111006 SBCA has created an alternate fall protection plan template, complete with links throughout the document to the applicable steps to follow in its online step-by-step approach to erecting an initial truss system under OSHA’s fall protection requirements.

CAUTIoN! Using a flat bottom chord gable end frame with adjacent trusses that have sloped bottom chords is prohibited by some building codes as adequate bracing of this condition is dif-ficult and sometimes impossible. Special end wall bracing design considerations are required by the building designer if the gable end frame profile does not match the adjacent trusses. ¡CAUTELA! El uso de un armazón hastial de la cuerda inferior con trusses contiguos cuales tienen cuerdas inferiores pendientes es prohibido por algunos códigos de edificios porque ar-riostre adecuado de esta condición es difícil y a veces imposible.

Handling, Installing, Restraining & Bracing of Trusses Manejo, Instalación, Restricción y Arriostre de los TrussesB1 B1WARN170120 Spreader bar for truss General Notes Trusses are not marked in any way to identify the frequency or location of tempo-rary lateral restraint and diagonal bracing. Follow the recommendations for handling, installing and temporary restraining and bracing of trusses. Refer to BCSI – Guide to Good Practice for Handling, Installing, Restraining & Bracing of Metal Plate Con-nected Wood Trusses*** for more detailed information. Truss Design Drawings may specify locations of permanent lateral restraint or reinforcement for individual truss members. Refer to the BCSI-B3*** for more information. All other permanent bracing design is the respon-sibility of the building designer. DANGER The consequences of improper handling, erecting, installing, restraining and bracing can result in a collapse of the structure, or worse, serious personal injury or death.. CAUTION Exercise care when removing banding and handling trusses to avoid damaging trusses and prevent injury. Wear personal protective equipment for the eyes, feet, hands and head when working with trusses. Handling Avoid lateral bending. The contractor is responsible for properly receiving, unloading and storing the trusses at the jobsite. Unload trusses to smooth sur-face to prevent damage. þ Trusses may be unloaded directly on the ground at the time of delivery or stored temporarily in contact with the ground after delivery. If trusses are to be stored for more than one week, place blocking of sufficient height beneath the stack of trusses at 8' (2.4 m) to 10’ (3 m) on-center (o.c.). þ If trusses are to be stored for more than one week, cover bundles to protect from the environment. Refer to BCSI*** for more detailed information pertaining to handling and jobsite storage of trusses. CAUTION Use special care in windy weather or near power lines and airports. þ Use proper rigging and hoisting equipment. Notas Generalas Los trusses no están marcados de ningún modo que identifique la frecuencia o local-ización de restricción lateral y arriostre diago-nal temporales.

Hip Set Assembly and Bracing Ensamblaje y Arriostre del Grupo de Cadera Permanently connecting the end jacks to the end wall and girder as early in the installation process as possible dramatically increases the stability of the hip girder and the safety of the structure. Conectando permanentemente los gatos extremos a la pared extremo y el travesaño tan temprano en el proceso de instalación como sea posible aumenta drásticamente la estabilidad del travesaño de cadera (hip girder) y la seguridad de la estructura. Use the following sequence: Use la siguiente secuencia: Step 1 Position the hip girder on the bearing walls at the specified end wall setback and permanently attach to supports. Posicione el travesaño de cadera en las paredes de soporte al "setback" especificado de la pared extremo y sujete a los soportes permanentemente. Whenever possible, connect multi-ply girder trusses together and install the end jack hangers (if required) prior to erection/installation. All plies of a multi-ply girder shall be attached per the fastening schedule on the TDD before attaching any framing members or applying any loads. Siempre que sea posible, conecte los trusses de travesaño de varias-capas juntos y instale los colgadores de gato extremo (si requerido) antes de la erección/instalación. Todas capas de un travesaño de varias capas sujetarán por el horario de fijar en el dibujo del diseño de truss antes de sujetar algunos miembros de arriostre o de aplicar algunas cargas. Step 2 Install hip jacks, and end jacks at maximum 10’ on-center while crane continues to hold girder in place. Instale los gatos de cadera y los gatos extremos a 10 pies máximo en centro mientras la grúa continúa mantener el travesaño en lugar. Note: Attach jack trusses to top chord and bottom chord of girder truss. The connection to the top chord is important as it helps to stabilize the top chord of the girder. Sujete los trusses de gatos a la cuerda superior y la cuerda inferior del truss de travesaño. La conexión por encima es importante porque ayuda a estabilizar la cuerda superior del travesaño. Step 3 Install all remaining side and end jacks with all permanent truss-to-bearing connections (e.g., hangers and tie-downs). Instale todos los gatos extremos y gatos de rincón restantescon todas las conexiones permanentes de truss-a-soporte (Ej. colgadores y soportes de anclaje). Step 4 Install the next hip truss with 2x4 short member temporary lateral restraints. Attach each short member temporary lateral restraint to the top chord of the hip girder and adjacent hip truss with two nails at each connection. The short member temporary lateral restraints should be long enough to extend at least 1 1/2" past the top chord of each truss. Place short member temporary lateral restraints at pitch breaks and at intervals along the top chords in accordance with Step 2 on page 2. Instale el próximo truss de cadera con 2x4 restricciones laterales temporales para miembros cortos. Sujete cada restricción lateral temporal del miembro corto a la cuerda superior del travesaño de cadera y al truss de cadera contiguo con dos clavos a cada conexión. Las restricciones laterales temporales para miembros cortos deben ser bastante largo para extender a un mínimo de 1 ½” pasado de la cuerda superior de cada truss. Puse la restricción lateral temporal de miembros cortos a roturas del pendiente y a intervalos por las cuerdas superiores según el Paso 2 en la página 2. Step 5 Install remaining hip trusses. For the flat portion of each hip truss, use short member temporary lateral restraints that are at least double the length of the first set of short member temporary lateral restraints (see Figure on next page). For the sloped chords of the trusses, install short member temporary lateral restraints according to one of the three options in Step 4 on page 3. Instale los restantes de los trusses de cadera. Para la parte plana de cada truss de cadera use restricciones laterales temporales de miembros cortos que son por lo menos dobles la longitud del primer grupo de restricciones temporales laterales de miembros cortos (vea la figura en la próxima página). Para las cuerdas pendientes de los trusses, instale las restricciones laterales temporales de miembros cortos según uno de las tres opciones en Paso 4 en la página 3.

Properly restrain and brace trusses before stacking construction materials on them. Diagonal BracingLateral Restraint Structural Sheathing Construction Loading DO's and DON’Ts DON’T stack materials on unbraced trusses. DON’T overload the trusses. DON’T exceed stack heights listed in the table. Construction loads are those loads imposed on the unfinished building as a result of the construction process. Typical construction loads in-clude the weight of the work-ers, equipment, and building materials, to name a few. For example, a bundle of plywood sheathing or gypsum board stacked on trusses temporar-ily creates construction loads. þ Make sure that the truss assembly is properly restrained and braced according to the guidelines in BCSI-B1*** and BCSI-B2*** before placing any construction loads on them. Construction loads shall only be placed on fully restrained and braced structures. WARNING Stacking excessive amounts of construction materials on floor or roof trusses is an unsafe practice. Prop-erty damage, personal injury and/or death are possible if this warning is not heeded. Trusses that have been over-stressed due to excessive construction loading will usually show excessive sagging (deflec-tion) and at least a portion of this deflection will remain even after the load has been removed. In more severe cases, broken truss members and/or failed truss joints may result. Maximum Stack Height for Material on Trusses1,2 Maximua Altura de Montón para Material encima de los Trusses Material – Material Height – Altura Gypsum Board – Tabla de Yeso 12" – 12 pulgadas Plywood or OSB – Madera Contrachapada u OSB 16" – 16 pulgadas Asphalt Shingles – Teja de Asfalto 2 bundles – 2 paquetes Concrete Block – Bloque de Hormingón 8" – 8 pulgadas Clay Tile – Teja de Arcilla 3-4 tiles – 3-4 azulejos Cargas de construcción son las cargas que están impuestas a los edi-ficios incompletos como resultado del proceso de construcción. Cargas de construcción típicas incluyen el peso de los trabajadores, el equipo y los materiales de construcción, etcétera. Por ejemplo, un paquete de entablado contrachapado o tabla de yeso apila-dos temporalmente sobre los trusses crean cargas de construcción. þ Asegúrese que el montaje del truss está adecuadamente restringido y arriostrado según las pautas en BCSI-B1*** y BCSI-B2 *** antes de colocar alguna carga de construcción en la estructura. Solamente coloquen cargas de construcción arriba de estructuras cuales son restringidos y arriostrados completamente. ¡ADVERTENCIA! Apilando cantidades excesivas de cargas de construcción sobre trusses de piso u techo es una práctica peligrosa. Daño a la propiedad, herida personal y/o muerte son posibles si no sigue esta advertencia. Los trusses que han sidos demasiado estresados debido a car-gas de construcción excesivas usualmente demuestran una des-viación excesiva, y por lo menos una parte de este desviación se quedarán aún después de que la carga se haya quitada. En casos más severos, miembros quebrados del truss y/o junturas falladas pueden resultar. 1 This table is based on trusses designed with a live load of 40 psf or greater. For other loading conditions, contact a Registered Design Professional.2 Limit stacking periods to approximately one week, unless alternative information is provided by the Building Designer, Truss Designer or Truss Manufacturer.B4ConstLoad 170831 Que HACER y NO HACER Con Las CargasDe Construccion NO amontone materiales sobre trusses que no esten arriostrados.

NO apile tile de sobra y/o otros residuos de construcción sobre los trusses. Girder Truss Cantilever DON’T allow the stack to lean against walls, or stack materials so they overload single or small groups of trusses. þ DO stack materials along ex-terior supports or directly over interior supports of properly restrained and braced structures. DON’T stack materials at or near the midspan of the truss. Never exceed stack heights provided in the table (see page 1) unless alternative information is provided by the Building Designer, Truss Designer or Truss Manufacturer. DON’T drop materials on trusses. The impact can damage the trusses even if the weight of the material is small. DON’T stack materials at locations that will produce instability, such as on cantilevers, overhangs or near truss-to-girder connections. þ DO leave construction materials on lifting equipment until installa-tion, if possible. DON’T pile cut-off tile and/or other construction waste on trusses. Job Number: J1803794 Publication printed or distributed by Builders FirstSource with permission of the Structural Building Components Association (SBCA) and the Truss Plate Institute (TPI). Regulations on fall protection and erection/installation of trusses in residential construction are contained in OSHA’s Fall Protec-tion Standard, 29 CFR 1926 Subpart M(the Standard). Section 1926.501(b)(13) of the Standard states in part: “Each employee engaged in residential construction activities 6 feet or more above lower levels shall be protected by guardrail systems, scaf-folding, a safety net system or a personal fall arrest system.” Las regulaciones sobre protección contra caídas y levantamiento/instalación de entramados en construcción residencial vienen contenidos en la Regulación de Protección contra Caídas de OSHA, 29 CFR 1926 Subparte M (el Estándar). La sección 1926.501(b)(13) de la regulación establece en parte: “Cada empleado que participe en actividades de construcción residencial a 6 pies o más por encima de niveles inferiores deberán estar protegidos por sistemas de rampas de protección, andamiaje, un sistema de red de seguridad o un sistema de protección personal para detención de caídas.” DANGER Any part of an inad-equately braced or sheathed roof or floor truss system used as an anchorage point for any type of personal fall arrest system is dangerous and will increase the risk of serious injury or death. WARNING Roof and floor trusses that are not properly braced per BCSI or sheathed are not able to resist lateral impact loads associated with falls. A falling worker attached to an inadequately braced set of trusses could cause all the previously set trusses to col-lapse in a domino effect.  Refer to BCSI-B1* and BCSI-B2 for recommendations on proper bracing of trusses. Consulte BCSI-B1* sobre recomendaciones para levantar correcto de los entramados. ¡PELIGRO! No camine sobre entramados no apuntalados. ¡PELIGRO! No se pare en el braguero voladizos hasta revestimiento estructural se ha aplicado a la armadura y voladizos.B11Fall 170726 SBCA has created an alternate fall protection plan template, complete with links throughout the document to the applicable steps to follow in its online step-by-step approach to erecting an initial truss system under OSHA’s fall protection requirements. Visit sbcindustry.com/fp Truss Systems Sistemas de Entramama ¡PELIGRO! Cualquier pieza de un sistema de entramado de techo o el piso apuntalado o forrado de forma inadecua-da que se utilice como punto de anclaje para cualquier tipo de sistema de protec-ción personal para detención de caídas es peligroso y aumentará el riesgo de lesiones personales de gravedad o la muerte. ¡ADVERTENCIA! Los entramados de techo y piso que no están correctamente apuntalados según BCSI o forrados no pueden resistir cargas de impacto lateral asociadas con caídas. Un trabajador que sufra una caída y que esté acoplado a un conjunto de entramados que no estén apuntalados adecuadamente podría pro-vocar que los entramados fijados previa-mente se colapsen con un efecto dominó.  Refer to BCSI-B1* for recom-mendations on proper hoisting of trusses. DANGER Do not walk on unbraced trusses. DANGER Do not stand on Truss over-hangs until Structural Sheathing has been applied to the Truss and overhangs. Fall Protection & Trusses Protección de Caída y TrussesB11 Job Number: J1803794 Publication printed or distributed by Builders FirstSource with permission of the Structural Building Components Association (SBCA) and the Truss Plate Institute (TPI). Site-Specific Job Hazard Assessment Fall protection and safety measures are jobsite and building specific. The appropriate fall protection method must be determined through a site-specific job hazard assessment (JHA) conducted by a qualified person (1) who can design, install, and use fall protection systems and is authorized to correct any problems. The JHA is in-tended to assist in identifying risks and identify the least hazardous way to install trusses for a particular job. Fall hazards identified in the JHA shall be addressed with conventional methods whenever possible, including: guardrails, scaffolding, safety nets, personal fall arrest systems or catch platforms. Employers must consider whether it is safer to design and install a safe work platform/system around a hazard. WARNING All fall protection solutions come with their own inherent hazards during use. CAUTION Addressing fall protection hazards may be obvious, but other hazards must also be considered when choosing the appropriate site-specific fall protec-tion systems. This includes: 1. electrical hazards, including power lines; 2. projectile hazards while using pneumatic nail guns; 3. tripping hazards from cords and bracing materials; and, 4. lower level hazards, such as wall bracing, which some fall protection systems do not protect against. DANGER Do not walk on trusses or gable end frames ly-ing flat, they do not have the structural strength to support a worker safely while oriented flat. Evaluación de Peligros de Trabajos en Sitios Específicos La protección contra caídas y las medidas de seguridad son específicas para cada sitio de trabajo o edificio. El método apropiado para la protección contra caídas de-berá determinarse siguiendo una evaluación de peligros en el trabajo (JHA) específicos, realizados por una per-sona que esté calificada (1) que pueda diseñar, instalar y utilizar sistemas de protección para caídas, y que esté autorizada para corregir cualquier problema. La JHA tiene el propósito de ayudar en la detección de riesgos e identificar la forma menos peligrosa para instalar entra-mados para un trabajo en particular. Los peligros sobre de caídas identificados en la JHA serán tratados con métodos convencionales cuando sea posible como, por ejemplo: rampas de protección, andamiaje, redes de seguridad, sistema de protección personal para detención de caídas o plataformas de agarre. Los empleados deberán considerar si es seguro diseñar e instalar una plataforma/sistema de trabajo seguro alrededor de un peligro. ¡ADVERTENCIA! Todas las soluciones de protección contra caídas vienen con sus propios peligros durante el uso. ¡CAUCIÓN! La solución de peligros para la protección contra caídas puede ser obvia, pero deberán consider-arse otros peligros al al elegir los sistemas de protección contra caídas apropiados para un sitio específico. Esto incluye:1. peligros de carácter eléctrico, como líneas de conduc-ción eléctrica; 2. peligros de objetos lanzados violentamente por el uso de engrapadoras neumáticas tipo pistola; 3. peligros de tropiezos por cables y materiales de apunta lamiento; y, 4. peligros de niveles bajos, como un apuntalamiento de pared, contra lo que no protegen los sistemas de protección contra caídas. ¡PELIGRO! No camine sobre entramados ni estruc-turas de muro piñón dispuestos horizontalmente ya que no poseen la resistencia estructural para poder soportar a un trabajador con seguridad con orientación horizontal. Job Number: J1803794 Publication printed or distributed by Builders FirstSource with permission of the Structural Building Components Association (SBCA) and the Truss Plate Institute (TPI). Fall Protection Equipment Installation DANGER Individual trusses alone are NOT designed to SUPPORT fall protection equipment. The Contractor is responsible for the construction means, methods, techniques, sequences, procedures, programs, and safety in connection with the receipt, storage, handling, installation, restraining, and bracing of trusses.  Refer to ANSI/ASSE Z359.2-2007, Minimum Require-ments for a Comprehensive Managed Fall Protection Program, for guidance in meeting minimum fall protec-tion equipment installation and use requirements. This standard refers to equipment only, and does not apply to the underlying structure to which the equipment is attached.(2) CAUTION While the equipment itself may resist the forces generated by a falling worker, it is up to a quali-fied person to determine whether the building’s struc-tural system to which the fall protection equipment is attached meets or exceeds this standard as well. ScaffoldingUse of interior or exterior scaffolding as a fall arrest system is permitted, but installation and use must adhere to the Standard requirements in 29 CFR 1926.500. Guard RailsUse of guard rails along the perimeter of the work area as a fall arrest system is permitted, but installation and use must adhere to the Standard requirements in 29 CFR 1926.500. Roof Peak Anchors WARNING Completely brace, per BCSI-B1* and BCSI-B2* or sheath trusses, before installing a roof anchor for use as personal fall restraint system. Installation and use must adhere to the Standard requirements in 29 CFR 1926.500. WARNING It is always safest to sheath a section (e.g. 3 or more trusses) of the roof system before installing a roof anchor for use as a personal fall restraint system. In-stallation and use must adhere to the Stan-dard requirements in 29 CFR 1926.500. Instalación de Equipo de Protección Contra Caídas ¡PELIGRO! Los entramados individuales por sí solos NO están diseñados para SOPORTAR equipo de protec-ción contra caídas. El contratista será responsable de los medios de con-strucción, los métodos, las técnicas, las secuencias, los procedimientos, los programas y la seguridad en lo que se refiere a recepción, almacenamiento, manejo, insta-lación, restricción y apuntalamiento de entramados. Consulte ANSI/ASSE Z359.2-2007, Minimum Require-ments for a Comprehensive Managed Fall Protection Program (Requisitos mínimos para un programa com-pleto de protección contra caídas) si desea información para el cumplimiento de los requisitos mínimos para la instalación y uso de equipo de protección contra caídas. Esta norma se refiere a equipo solamente, y no es apli-cable a la estructura subyacente a la que esté acoplado el equipo.(2) ¡CAUCIÓN! Aunque el equipo por sí mismo puede resistir las fuerzas generadas por la caída de un tra-bajador, es responsabilidad de una persona calificada determinar si el sistema estructural del edificio al que se acopla el equipo de protección contra caídas cumple o supera está regulación también. AndamiajeEstá permitido el uso de andamiaje interior o exterior como sistema para detención de caídas, pero la insta-lación y el uso deberá adherirse a los requisitos regula-torios descritos en 29 CFR 1926.500. Rampas de ProtecciónSe permite el uso de rampas de protección a lo largo del perímetro del área de trabajo como sistema para detención de caídas, pero la instalación y el uso de-berán adherirse a los requisitos de la regulación que se encuentran en 29 CFR 1926.500. Anclajes de Tejado¡ADVERTENCIA! Apuntale completamente, según BCSI-B1* y BCSI-B2* o forre los entramados, antes de instalar un anclaje de tejado para su uso como sistema personal de restricción de caídas. La instalación y el uso deberá adherirse a los requisitos regulatorios que se indican en 29 CFR 1926.500. ¡ADVERTENCIA! Siempre es más seguro forrar una sección (por ejemplo, 3 o más entra-mados) del sistema de tejado antes de instalar un anclaje de tejado para uso como sistema personal de restricción de caídas. La instalación y el uso deberá adherirse a los requisitos regulatorios que se indi-can en 29 CFR 1926.500.

Las medidas alternativas del plan de protección contra caídas deberán aplicarse a trabajadores suficientemente capacitados y experimentados (5), y el plan deberá cumplir los requisitos de 29 CFR 1926.502(k) y ser específicas para cada sitio. El uso de medidas alternativas se utilizará en conjunción con sistemas de protección contra caídas (6), y el uso de métodos alternativos será lo más limitado posible. Montaje en el terrenoRealice el montaje previo de un sistema de entramado en el terreno. Restrinja lateralmente por completo y apuntale diago-nalmente la cuerda inferior y los planos de la pieza de enrejado según BCSI-B1* y BCSI-B2.* Apuntale completamente, según BCSI-B1* y BCSI-B2,* o forre el plano de la cuerda superior, para conseguir la estabilidad adecuada. Alce y establezca en su lugar. Esta sección previamente montada puede utilizarse entonces como un punto de acoplamiento para anclaje de restricción per-sonal contra caídas. Definiciones(1) Bajo 29 CFR 1926.503(a)(2), una persona calificada es aquella que debe tener conocimientos y aptitud para proporcionar capacitación a otros, en las áreas siguientes: “la naturaleza de los peligros de caída en el área de trabajo; los procedimientos correctos para levantar, mantener, desmontar e inspeccionar los sistemas de protección contra caídas a utilizarse; el uso y la operación de sistemas de rampas de protección, sistemas personales para detención de caídas, sistemas de redes de seguridad, sistemas de líneas de advertencias, sistemas de monitoreo de seguridad, zonas de acceso controlado y otra protección a utilizarse; la función de cada empleado en el sistema de monitoreo de seguridad cuando se utilice este sistema; las limitaciones sobre el uso de equipos mecánicos durante la realización de trabajo en tejados de baja pendi-ente; los procedimientos correctos para el manejo y almacenamiento de equipo y materiales, y la construcción de protección superior; y la función de los empleados en planes de protección contra caídas”.(2) El comentario E5.4.2.2 de ANSI/ASSE Z359.2-2007 establece, “El impacto de las fuerzas de caída sobre vigas, columnas y sus soportes que no sean anclajes no se tratan en esta norma”.(3) Según 29 CFR 1926.500(b), irrealizable significa “que es imposible llevar a cabo el trabajo de construcción usando un sistema convencional de protección contra caídas (por ejemplo, sistemas de rampas de protec-ción, sistema de red de seguridad o sistema de protección personal para detención de caídas), o que es tecnológicamente imposible usar cualqui-era de estos sistemas para proporcionar protección contra caídas”.(4) 29 CFR 1926.501(b)(2)(i) establece que, “hay una suposición de que es realizable y que no se creará un peligro mayor al implementar al menos uno de los sistemas de protección contra caídas [indicados]. Por consiguiente, el empleador tiene la responsabilidad de establecer que es apropiado implementar un plan de protección contra caídas que se adhiera a 1926.502(k) para una situación particular en el lugar de trabajo, en lugar de implementar cualquiera de esos sistemas”.(5) 29 CFR 1926.503(a)(1) establece que “el programa del empleador permitirá a cada empleado poder reconocer los peligros de caídas y ca-pacitará a cada empleado en los procedimientos a seguir para minimizar estos peligros”.(6) Según 29 CFR 1926.500(b), los sistemas convencionales de protec-ción contra caídas son: “sistema de rampas de protección, sistema de red de seguridad o sistema de protección personal para detención de caídas”. *Contact the component manufacturer for more information or consult a Professional Engineer for assistance. Alternative Fall Protection Plans After conducting a JHA, if the qualified person is able to demon-strate that conventional fall protection measures are infeasible (3) or present a greater hazard (4) to a particular worker or the entire crew, an employer may implement a written alternative fall protec-tion plan in compliance with residential construction fall protection under 29 CFR 1926.501(b)(13). The fall protection plan’s alternative measures must apply to suf-ficiently trained and experienced workers (5), and the plan must meet the requirements of 29 CFR 1926.502(k) and be site-specific. The use of alternative measures shall be used in conjunction with conventional fall protection systems (6), and the use of alternative methods shall be as limited as possible. Ground Assembly Pre-assemble a truss system on the ground.

Definitions(1) Under 29 CFR 1926.503(a)(2), a qualified person is one who should have knowledge, and be able to provide training to others, in the following areas: “the nature of fall hazards in the work area; the correct procedures for erecting, maintaining, disassembling, and inspecting the fall protection systems to be used; the use and operation of guardrail systems, personal fall arrest systems, safety net systems, warning line systems, safety moni-toring systems, controlled access zones, and other protection to be used; the role of each employee in the safety monitoring system when this sys-tem is used; the limitations on the use of mechanical equipment during the performance of roofing work on low-sloped roofs; the correct procedures for the handling and storage of equipment and materials and the erection of overhead protection; and, the role of employees in fall protection plans.”(2) Commentary E5.4.2.2 of ANSI/ASSE Z359.2-2007 states, “The impact of fall forces on beams, columns and their supports other than anchorages are not addressed by this standard.”(3) Under 29 CFR 1926.500(b), infeasible means “that it is impossible to perform the construction work using a conventional fall protection system (i.e., guardrail system, safety net system, or personal fall arrest system) or that it is technologically impossible to use any one of these systems to provide fall protection.”(4) 29 CFR 1926.501(b)(2)(i) states, “there is a presumption that it is feasible and will not create a greater hazard to implement at least one of the [listed] fall protection systems. Accordingly, the employer has the burden of establishing that it is appropriate to implement a fall protection plan which complies with 1926.502(k) for a particular workplace situation, in lieu of implementing any of those systems.”(5) 29 CFR 1926.503(a)(1) states, “the employer program shall enable each employee to recognize the hazards of falling and shall train each employee in the procedures to be followed in order to minimize these hazards.”(6) Under 29 CFR 1926.500(b), conventional fall protection systems are: “guardrail system, safety net system, or personal fall arrest system.” Z:\jobs\orders\masters\001TrussDesign\Docs\Commercial truss Submittal Forms\General Warnings.doc revised 8/6/2008 20815 67th Avenue, Arlington, WA 98223 360-925-4155 Warnings: 1.

In regards to the above mentioned subject the engineering note on the End Jack trusses referring to “Beveled plate or shim required to provide full bearing surface with truss chord at joint(s) (__).” Does not require a shim, provided the Roof Live Load (Roof Snow included) is less than or equal to 40 psf. This is referring to the top chord bearing condition at End Jack trusses bearing on the Hip Truss flat top chord. An acceptable condition would provide support where indicated and connection by others or (2)-16d common wire (0.162” dia. x 3.5” long) Toe-Nails at each End Jack top chord to Hip Truss top chord, not to exceed 4’ on center along the extension of the End Jack top chord. This is considered a Mechanical Connection. Maximum uplift not to exceed 170 lbs. Anchor hardware required for uplift exceeding 170 lbs.

The following devices will be used to trap sediment from the cleared areas and prevent it from leaving the site. A construction entrance will be installed at the entrance to the site to keep sediment from being tracked out of the site and onto the County roads. Mirafi silt fences will be installed along the perimeter to stop any sediment runoff from exiting the project limits. The following general Washington State Elements shall be upheld at all times during the construction process. Please reference the BMP section in this report. Element #1: Preserve Vegetation/Mark Clearing Limits  Prior to beginning land disturbing activities, including clearing and grading, clearly mark all clearing limits, sensitive areas and their buffers, and trees that are to be preserved within the construction area. These shall be marked, both in the field and on the plans, to prevent damage and offsite impacts.  The duff layer, native topsoil, and natural vegetation shall be retained in an undisturbed state to the maximum degree practicable.  Plastic, metal, or stake wire fence may be used to mark the clearing limits.  Suggested BMPs: - D.2.1.1.1: Plastic or Metal Fence Element #2: Establish Construction Access  Construction vehicle access and exit shall be limited to one route, if possible.  Access points shall be stabilized with a pad of quarry spalls, crushed rock or other equivalent BMP, to minimize the tracking of sediment onto public roads.  Wheel wash or tire baths should be located on site, if the stabilized construction entrance is not effective in preventing sediment from being tracked onto public roads. If a wheel wash is used it should be self contained. Track out is not allowed per City of Auburn Surface Water Management Manual.  Construction access restoration shall be equal to or better than the pre- construction condition. D08-053 B18005659 V1 RECEIVED 10/10/2018 aalexander BUILDING DIVISION  Suggested BMPs: - D.2.1.4.1: Stabilized Construction Entrance Element #3: Control Flow Rates  Properties and waterways downstream from development sites shall be protected from erosion due to increases in the velocity and peak volumetric flow rate of stormwater runoff from the project site, as required by local plan approval authority. Element #4: Install Sediment Controls  Stormwater runoff from disturbed areas shall pass through a sediment pond or other appropriate sediment removal BMP, prior to leaving a construction site or prior to discharge to an infiltration facility. Runoff from fully stabilized areas may be discharged without a sediment removal BMP, but shall meet the flow control performance standard of S9.D.3.a.  Sediment control BMPs (sediment ponds, traps, filters, etc.) shall be constructed as one of the first steps in grading. These BMPs shall be functional before other land disturbing activities take place.  BMPs intended to trap sediment on site shall be located in a manner to avoid interference with the movement of juvenile salmonids attempting to enter off- channel areas or drainages.  Suggested BMPs: - D.2.1.3.1: Silt Fence Element #5: Stabilize Soils  Exposed and unworked soils shall be stabilized by application of effective BMPs that prevent erosion. Applicable BMPs include, but are not limited to: temporary and permanent seeding, sodding, mulching, plastic covering, erosion control fabrics and matting, soil application of polyacrylamide (PAM), the early application of gravel base on areas to be paved, and dust control.  Depending on the geographic location of the project, no soils shall remain exposed and unworked for more than the time periods set forth below to prevent erosion: West of the Cascade Mountains Crest: During the dry season (May 1 – Sept. 30): 7 days During the wet season (October 1 – April 30): 2 days The time period may be adjusted by a local jurisdiction, if the Jurisdiction can show that local precipitation data justify a different standard.  Soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on the weather forecast.  Soil stockpiles must be stabilized from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels.  Suggested BMPs: - D.2.1.2.2: Mulching - D.2.1.2.4: Plastic Covering - D.2.1.2.6: Temporary and Permanent Seeding - D.2.1.2.7: Sodding - D.2.1.8: Dust Control Element #6: Protect Slopes  Design and construct cut and fill slopes in a manner that will minimize erosion. Applicable practices include, but are not limited to, reducing continuous length of slope with terracing and diversions, reducing slope steepness, and roughening slope surfaces (e.g., track walking).  Off-site stormwater (run-on) or groundwater shall be diverted away from slopes and disturbed areas with interceptor dikes, pipes, and/or swales. Off-site stormwater should be managed separately from stormwater generated on the site.  At the top of slopes, collect drainage in pipe slope drains or protected channels to prevent erosion. West of the Cascade Mountains Crest: Temporary pipe slope drains shall handle the peak 10-minute velocity of flow from a Type 1A, 10-year, 24-hour frequency storm for the developed condition. Alternatively, the 10-year, 1-hour flow rate predicted by an approved continuous runoff model, increased by a factor of 1.6, may be used. The hydrologic analysis shall use the existing land cover condition for predicting flow rates from tributary areas outside the project limits. For tributary areas on the project site, the analysis shall use the temporary or permanent project land cover condition, whichever will produce the highest flow rates. If using the WWHM to predict flows, bare soil areas should be modeled as “landscaped area."  Excavated material shall be placed on the uphill side of trenches, consistent with safety and space considerations.  Check dams shall be placed at regular intervals within constructed channels that are cut down a slope.  Suggested BMPs: - D.2.1.2.6: Temporary and Permanent Seeding Element #7: Protect Drain Inlets This element is not applicable due to there being no drain inlets on or in the direct vicinity of the site. Element #8: Stabilize Channels and Outlets This element is not applicable because 100% of the stormwater will be controlled onsite via dispersion BMP’s. Element #9: Control Pollutants  All pollutants, including waste materials and demolition debris, that occur on site during construction shall be handled and disposed of in a manner that does not cause contamination of surface water.  Cover, containment, and protection from vandalism shall be provided for all chemicals, liquid products, petroleum products, and other materials that have the potential to pose a threat to human health or the environment. On-site fueling tanks shall include secondary containment.  Maintenance, fueling, and repair of heavy equipment and vehicles shall be conducted using spill prevention and control measures. Contaminated surfaces shall be cleaned immediately following any spill incident.  Wheel wash or tire bath wastewater shall be discharged to a separate on-site treatment system or to the sanitary sewer with local sewer district approval.  Application of fertilizers and pesticides, shall be conducted in a manner and at application rates that will not result in loss of chemical to stormwater runoff. Manufacturers’ label requirements for application rates and procedures shall be followed.  BMPs shall be used to prevent or treat contamination of stormwater runoff by pH modifying sources. These sources include, but are not limited to: bulk cement, cement kiln dust, fly ash, new concrete washing and curing waters, waste streams generated from concrete grinding and sawing, exposed aggregate processes, dewatering concrete vaults, concrete pumping and mixer washout waters. Permittees shall adjust the pH of stormwater if necessary to prevent violations of water quality standards.  Permittees shall obtain written approval from Ecology prior to using chemical treatment, other than CO2 or dry ice to adjust pH.  Suggested BMPs: - D.2.2.1: Concrete Handling Element #10: Control Dewatering  If dewatering is anticipated or encountered during construction, contractor shall contact a Source Control Representative with the City of Auburn at (253) 876- 1969. Dewatering may require a Special Approved Discharge permit.  Foundation, vault, and trench dewatering water, which have similar characteristics to stormwater runoff at the site, shall be discharged into a controlled conveyance system prior to discharge to a sediment trap or sediment pond.  Clean, non-turbid dewatering water, such as well-point ground water, can be discharged to systems tributary to, or directly into surface waters of the state, as specified in S9.D.8, provided the de-watering flow does not cause erosion or flooding of receiving waters. Clean de-watering water should not be routed through stormwater sediment ponds.  Other disposal options may include: 1. Infiltration; 2. Transport off-site in a vehicle, such as a vacuum flush truck, for legal disposal in a manner that does not pollute state waters; 3. Ecology-approved on-site chemical or other suitable treatment technologies; 4. Sanitary sewer discharge with local sewer district approval, if there is no other option; or 5. Use of a sedimentation bag with outfall to a ditch or swale for small volumes of localized de-watering.  Highly turbid or contaminated dewatering water shall be handled separately from stormwater. Element #11: Maintain BMPs  All temporary and permanent erosion and sediment control BMPs shall be maintained and repaired as needed to assure continued performance of their intended function in accordance with BMP specifications.  All temporary erosion and sediment control BMPs shall be removed within 30 days after final site stabilization is achieved or after the temporary BMPs are no longer needed. Element #12: Manage the Project  Development projects shall be phased to the maximum degree practicable and shall take into account seasonal work limitations.  Inspection and Monitoring All BMPs shall be inspected, maintained, and repaired as needed to assure continued performance of their intended function. Site inspections and monitoring shall be conducted in accordance with S4.  Maintaining an Updated Construction SWPPP The SWPPP shall be maintained, updated, and implemented in accordance with Conditions S3, S4 and S9.

Within 14 days of receipt of the written request, the Permittee may submit a copy of the plans and records to Ecology for viewing and/or copying by the requestor at an Ecology office, or a mutually agreed upon location. If plans and records are viewed and/or copied at a location other than at an Ecology office, the Permittee will provide reasonable access to copying services for which a reasonable fee may be charged. The Permittee shall notify the requestor within 10 days of receipt of the request where the plans and records may be viewed and/or copied. SSEECCTTIIOONN 22 –– CCOONNSSTTRRUUCCTTIIOONN PPHHAASSIINNGG The proposed construction sequence will be as follows: 1. Hold the pre-construction meeting with King County staff. 2. Flag or fence clearing limits. 3. Post a sign with the name and phone number of the ESC supervisor. 4. Grade and install construction entrance(s). 5. Install perimeter protection (silt fence, brush barrier, etc.) 6. Grade and stabilize construction roads. 7. Construct surface and sub-surface water controls (interceptor swales/trenches, rock check dams, etc.) simultaneously with clearing and grading for project development. 8. Maintain erosion control measures in accordance with King County requirements and manufacturer’s recommendations. 9. Relocate surface controls or erosion control measures, or install new measures so that as site conditions change, the erosion and sediment control is always in accordance with King County. 10. Cover all areas that will be un-worked for more than seven days during the dry season or two days during the wet season with straw, wood fiber mulch, compost, plastic sheeting, or equivalent. 11. Stabilize all areas within seven days of reaching final grade. 12. Seed or sod any areas to remain un-worked for more than 30 days. 13. Upon completion of the project, stabilize all disturbed areas and remove BMP’s if appropriate.

The design team should address the comments below. Responses to these review comments should be made in an itemized letter form and any changes to the drawings should be clouded. We recommend that the permit applicant have the structural engineer respond and resubmit for additional review. All information should be submitted directly to the City of Renton. Geotechnical 1. Geotechnical special inspections. Special inspections and tests should be provided by a qualified geotechnical engineer as recommended in the geotechnical report by Associated Earth Sciences dated June 20, 2013. See IRC Section R401.4. The following is a summary: a. Site excavation and grading. b. Overexcavation for placement of structural fill. c. Construction dewatering, see Page 4 of geotechnical report. d. Placement of structural fill and soil compaction. e. Verification of soil-bearing capacity. Mr. Sorkness Page 2 of 3 November 4, 2018 No response from the applicant is required for this comment. This comment is for the building official and for reference Structural General 1. Structural special inspections. Structural special inspections. Special inspections by qualified special inspectors do not appear warranted for this project. If it is determined otherwise, the applicable special inspections are noted below. See IBC Sections 1704.1 and 1704.2. a. Installation of concrete expansion, adhesive, and screw anchors, where applicable: in accordance with qualifying report of evaluation service (e.g., ICC-ES). See also IRC Section 301.1.3 as well as IBC Section 1705.1.1. No response from the applicant is required for this comment. This comment is for the building official and for reference. 2. The drawings, such as Sheet S-0, should be revised to indicate the manufacturer’s installation instructions shall be available on the job site at the time of inspection, for the inspector’s use and reference. We strongly suspect this requirement is indicated the drawings, we just cannot find it. The revised drawings shall be resubmitted for reviews. See IRC Sections 106.1.1 and 106.1.2. Lateral 3. The rear exterior shear walls on the Upper Level of the proposed structure appear (as shown on the plans and calculations) to cause this framing scheme to be irregular by IRC Section R301.2.2.2.5 Items 1 through 5, especially Items 1 and 3. Per IRC Section R301.2.2.2.5, these shear walls and supporting elements shall be designed per acceptable engineering practice, i.e. the IBC and associated ASCE 7-10. These shear walls appear to cause a Type 4 horizontal, and so the supporting members shall be designed for increase forces, including increase in: chord forces, diaphragm connection forces to chords and collectors, etc…; as indicted by ASCE 7-10 Tables 12.3-1 and 12.3-2 as well as Sections 12.3.3.3 and 12.3.3.4. Below is an image of the current framing with redlines as the upper floor, the green lines as the main floor, and the yellow lines as our comment. The submitted calculations do not appear to Mr. Sorkness Page 3 of 3 November 4, 2018 address these irregularities. Please submit substantiating data, such as additional calculations, that indicate the proposed structure has the design capacity to resist the required IBC loadings. Please note, there is currently no collector in the Upper Floor framing to drag W2 shear loads to the Main Floor shear walls. The drawings may need to be revised to also show a complete load path from these shear walls to the foundation as per IRC Sections 301.1 and 301.1.3. Also see IBC Sections 1604.2, 1604.4, 1605.2, 1605.3, and 1613.1. Corrections and comments made during the review process do not relieve the permit applicant or the designers from compliance with code requirements, conditions of approval, and permit requirements; nor are the designers relieved of responsibility for a complete design in accordance with the laws of the state of Washington. This review is for general compliance with the International Residential Code and International Building Code as they relate to the project. See IRC Section 105.4. If you have any questions or need additional clarification, please contact us. Sincerely, Alan D. Findlay, P.E. Building Plan Reviewer, City of Renton cc: File
