L2 Engineers, LLC 17848 NE 198th Place Woodinville, WA 98072 Date: February 28, 2020 Re: 17-015: Grant Place Vault Dear Satwant: On December 12, 2019, L2 Engineers made a site visit to the Grant Place Vault located at 1600 Grant Ave S., to inspect the surface of the vault walls. We met several building officials from the City of Renton and reviewed two exterior wall surfaces. Walls were not properly consolidated during concrete placement, causing areas of unsound concrete that require repair. The entire surface (including internal walls, knee walls, and external walls) shall be inspected via impact by hammer, by a third-party special inspection firm. Testing shall be completed with impact hammer in accordance with ASTM D4580-12; methods noted in Section 1.2.1 and 1.2.3 are preferred. Sound concrete produces a distinct ring from a hammer blow, and the hammer will rebound sharply. Additionally, dragging a screwdriver across sound concrete will produce a shiny white streak. Unsound concrete produces a dull thud when struck with a hammer, and little to no rebound of the hammer. The concrete is unsound if the hammer indents and/or pulverizes the surface. Dragging a screwdriver across unsound concrete can scratch off surface powder. Unconsolidated, unsound concrete shall be removed by chipping and grinding as required to expose sound concrete. After all unsound concrete has been removed, a third-party special inspection firm shall verify that removal has occurred to a sufficient depth. The method of repair should then be selected from the following options based on the depth of the exposed area: • NO REPAIR REQUIRED – DEPTH OF ¼” OR LESS Damage which extends to a depth of ¼” or less can be regarded as cosmetic and does not require repair. • THIN REPAIRS – DEPTH FROM ¼” TO LESS THAN 2” Thin repairs shall be used where damage extends from greater than ¼” to a maximum depth of 2” inches and does not encompass any reinforcing steel. The perimeter of the repair area shall be saw cut square to a minimum depth of 3/8”. The remainder of the repair area may be removed by chipping below the vertical saw cut and continuing until the appropriate depth is reached. Patches shall consist of packaged cementitious repair mortar, in lifts as required by the manufacturer. We recommend SikaTop – 123 Plus for this application. Surface preparation shall be in accordance with the manufacturer’s application instructions. The application instructions for SikaTop-123 Plus can be found in the product data sheet, attached to this letter for reference. RECEIVED 02/28/2020 striplett BUILDING DIVISION B18004340_V4 L2 Engineers, LLC | 17848 NE 198th Place Woodinville, WA 98072 | TEL: 206-251-2346 • THICK REPAIRS – UP TO FULL WALL DEPTH Thick repairs shall be used where damage extends from greater than 2” to a maximum of the full depth of the wall, and may encompass reinforcing steel. The perimeter of the repair area shall be saw cut square to a depth of 1 inch. The remainder of the repair area may be removed by chipping below the vertical saw cut and continuing until the appropriate depth is reached. Reinforcing steel should not be left partially embedded. Instead, concrete should be removed around each bar to provide at least one inch of clearance, or the maximum aggregate size of the replacement concrete plus 1/4", whichever is greater. Patches shall consist of polymer modified self-consolidating concrete mix with corrosion inhibitor. We recommend Sikacrete -211 SCC Plus. The application instructions for Sikacrete – 211 SCC Plus can be found in the product data sheet, attached to this letter for reference. Please note that vertical and horizontal surfaces will need to be formed and pumped or poured. The following inspection requirements must be satisfied: 1. A licensed third-party inspector is required to be present during placement of repair material. The inspector shall provide continuous special inspection during this phase of work. After patching repairs have been completed in accordance with the above recommendations, inspection of the patch repairs by a licensed third-party inspector is required. 2. A Sika Representative must be onsite twice during the repair process. Once to prior to the start of the repairs, to explain the requirements associated with the use their repair products to the general contractor (for both thin and thick repairs) and once to review the completed repairs after they have cured and prior to lid placement (for both thin and thick repairs.) The third-party special inspector shall also be on site when the Sika Representative is on site. Frank Calabrese, a District manager with the Sika Corporation, has offered to assist with the two required site visits. Mr. Calabrese phone number is: 201-933-8800, and his email address is calabrese.frank@us.sika.com. Mr. Calabrese will require as much advanced notice as possible prior to scheduling site visits. 3. Prior to lid placement, the repaired areas shall cure for a minimum length of time as specified by Sika’s Product Data Sheets. After curing, the repairs shall be inspected by a Sika Representative to insure that the materials are not cracking or otherwise failing. 4. Upon completion of Sikas final review, the Sika Representative shall provide a memo stating that the repair materials were installed in accordance with their recommendations, and that the repair materials are not cracking or otherwise failing. The memo shall be provided to the Engineer of Record for transmittal to the City of Renton. Once the patches have been approved by the third party inspector and Sika, a waterproofing layer shall be applied to the interior surface of the perimeter vault walls. Waterproofing product shall be Sikagard 7600 and shall be submitted to the City for review prior to use. Please feel free to contact us with any questions or concerns.

APPLICATION INSTRUCTIONS SURFACE PREPARATION Surface preparation Surface must be clean and sound. Remove all deteriorated concrete, dirt, oil, grease, and other bond- inhibiting materials from the area to be repaired. ▪ Be sure repair area is not less than 1/8" (3 mm) in depth. ▪ Preparation work should be done by high pressure water blast, scabbler or other appropriate mechanical means to obtain an exposed aggregate surface profile of ±1/16" (1.6 mm) (CSP-5). ▪ To ensure optimum repair results, the effectiveness of decontamination and preparation should be assessed by a pull-off test. ▪ Saw cutting of edges is preferred and a dovetail is recommended. ▪ Substrate should be Saturated Surface Dry (SSD) with clean water prior to application. No standing water should remain during application. ▪ Priming Reinforcing steel: Steel reinforcement should be thoroughly prepared by mechanical cleaning to remove all traces of rust. Where corrosion has occurred due to the presence of chlorides, the steel should be high pressure washed with clean water after mechanical cleaning. For priming of reinforcing steel use Sika® Armatec® 110 EpoCem (consult PDS). ▪ Concrete Substrate: Prime the prepared substrate with a brush or sprayed applied coat of Sika® Armatec® 110 EpoCem (consult PDS).Alternately, a scrub coat of SikaTop®-123 Plus can be applied prior to placement of the mortar. The repair mortar has to be applied into the wet scrub coat before it dries. ▪ MIXING Pour Component ‘A’ into mixing container.▪ Add Component ‘B’ while mixing continuously.▪ Mix mechanically with a low-speed drill (400–600 rpm) and mixing paddle or mortar mixer. ▪ Mix to a uniform consistency, maximum 3 minutes.▪ Manual mixing can be tolerated only for less than a full unit. Thorough mixing and proper proportioning of the two components is necessary. ▪ APPLICATION SikaTop®-123 Plus must be scrubbed into the substrate, filling all pores and voids. ▪ Force material against edge of repair, working toward center. ▪ After filling repair, consolidate, then screed.▪ Material may be applied in multiple lifts.▪ Multiple lifts Where multiple lifts are required score top surface of each lift to produce a roughened surface for next lift. ▪ Allow preceding lift to reach initial set, 30 minutes minimum, before applying fresh material. ▪ Substrate should be Saturated Surface Dry (SSD) with clean water prior to application. No standing water should remain during application. ▪ Scrub fresh mortar into preceding lift.▪ Allow mortar or concrete to set to desired stiffness, then finish with wood or sponge float for a smooth surface. ▪ CURING TREATMENT As per ACI recommendations for Portland cement concrete, curing is required. ▪ Moist cure with wet burlap and polyethylene, a fine mist of water or a water based* compatible curing compound (ASTM C-309). ▪ Curing compounds adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings. ▪ Moist curing should commence immediately after finishing. ▪ Protect freshly applied mortar from direct sunlight, wind, rain and frost. ▪ * Pretesting of curing compound is recommended. LIMITATIONS Do not use solvent-based curing compound.▪ Size, shape and depth of repair must be carefully considered and consistent with practices recommended by ACI or ICRI. ▪ For additional information on substrate preparation, refer to ICRI Guideline No. 310.2R. ▪ If aggressive means of substrate preparation is employed, substrate strength should be tested in accordance with ACI 503 Appendix A prior to the repair application. ▪ As with all cement based materials, avoid contact with aluminum to prevent adverse chemical reaction and possible product failure.

Asphalt - New asphalt must be cured a minimum of 28 days prior to application. Old asphalt must be free of loose aggregate, dirt and be dry. New and old asphalt should be Shot-, Water- or Abrasive-blasted. Lower ambient temperature will help to make cleaning process more effective. Grease spots and oil should be cleaned with appropriate cleaners. Metal - Should be thoroughly cleaned by grinding or blast cleaning. Be aware of dew point and check it before every application on metal surface. Plywood - The only acceptable grade of plywood is APA rated exterior grade or better. The appearance and physical characteristics of the plywoodand grade should be considered. Plywood should be new or cleaned and sanded. Priming: To promote adhesion and minimize outgassing, priming is advised on all surfaces except for new plywood. New plywood priming is optional. Concrete, Metal, Old Plywood - Sikalastic® PF Lo-VOC Primer, recoat window: tack free to 16 hrs. Concrete - Sikalastic® MT Primer, recoat window: tack free to 48 hrs. Asphalt - Sikalastic® Recoat Primer, recoat window: tack free to 12 hrs. Mixing Mix each pail (4.05 gal.) of Sikagard® 7600 Part-B by using a mechanical mixer and jiffy style paddle at slow speed for 1.5 minutes minimum to ensure a homogeneous material. Take care not to allow entrapment of air into the material. Do not mix in an up and down motion. While mixing, slowly add one 0.45 gallon pail of Sikagard® 7600 Part-A to the pail. Once Part-A has been added , mix for 3 minutes. Please do not estimate to avoid any mixing errors. Do not thin. Do not hand mix. Mix the whole pail. Do not batch. Application Phase 1 ( Primer ): When required; prime the surface at the rate of 1 gal/200 sq.ft. (0.14 liters/m2). Apply using a brush or phenolic core roller. This will result in 5 dry mils (127 microns) of coating. Priming is optional. Don’t prime over an existing detail coat. NOTE : For rough or porous concrete or when outgassing is a concern, use Sikalastic® PF Lo-VOC Primer at an approximate rate of 180 sq.f/1 gal. (0.21liters/m2). This rate may vary on the porosity of the substrate. Allow primer to become tack free before proceeding to the next phase. Phase 2 ( Cracks, Joints, Detailing): Detail Coat: Apply 30 mils of detail coat Sikagard® 7600 over all joints, cracks and flashing. Reinforced Detail Coat: Apply 15 mils of detail coat Sikagard® 7600 over all joints, cracks and flashing. Bridge joints, cracks, and flashings with 3” or 6” FlexiTape Heavy pushing it into the Sikagard® 7600 over all joints, cracks and flashings. Over reinforcement tape, apply 10-15 mils stripe coat of Sikagard® 7600 and taper it onto adjacent surface. Allow the surface to cure for 1 - 2 hours before the next phase. Cracks in concrete/asphalt over 1/8” must be filled with Sikagard® 7600 .Using Sikagard® 7600 as caulking compound will shorten the curing time over conventional polyurethane caulks. Place 3” FlexiTape Heavy over freshly filled crack and apply 20 mils of Sikagard® 7600 detail coat. Allow to cure 2 - 4 hours before the next phase. Phase 3 ( Coat #1 ): The first coat of Sikagard® 7600 (mixture of Part-A and Part-B) should be applied at the rate of 50 sq.f/1 gal. (0.82 liters/m2) resulting in 30 dry mils (750 microns) of membrane . Allow to cure (2 - 4 hours) before proceeding to Phase 4. Phase 4 ( Coat #2 ): Apply the second coat of Sikagard® 7600 (mixture of Part-A and Part-B ) at the rate of 50 sq.ft./1gal. (0.82 liters/m2) resulting in 30 dry mils (750 microns) of membrane. NOTE: If priming is not required skip Phase 1, and proceed with Phase 2 Properly applied system Sikagard® 7600 will provide 60 dry mils (1500 dry microns). Any adhesion test is to be performed 7 days after product application. Sikagard 7600 HG: Can be applied over horizontal and vertical surface. Apply using a phenolic core roller 1/2” or brush. 3/16” notched squeege can be used only for horizontal application.
