This Guaranty is valid for one year from the date of submission of a test and balance report and may only be invoked in writing by the building owner, architect, or engineer of record. The Guaranty is limited to the terms and conditions as stated herein. Response to complaints will be provided within 10 business days of initial complaint. Pursuant to the agreement between Integra Testing Services,LLC and/or its subsidiaries (“Integra Testing”)and Client,all systems shall be tested,adjusted, and balanced in accordance with the project plans and specifications and to the optimum performance capabilities of the equipment.Testing and balancing shall be done in accordance with the standards published by the Associated Air Balance Council (AABC)and/or the National Environmental Balancing Bureau (NEBB). Submitted and Certified by: NEBB TAB Firm: Neudorfer Engineers Inc Certification No: 3856 Expiration Date: December 31, 2023 Certification Date: May 25, 2023 (Date completed) Signed and Sealed by: NEBB Supervisor: William C. Neudorfer Noted deficiencies are not Neudorfer Engineers responsibility to repair.Prior to issuance of this report, Deficiency Reports are forwarded to our contracted agent. Warranty is limited to one year from the date of substantial completion.Within that time,any discrepancies,ambiguities,or omissions found in this report will be retested, adjusted, or balanced as needed. A written notification will be required. Significant /Noteworthy Remarks are noted on the General Remarks and General Field Notes pages. Other remarks are noted on individual test sheets. CERTIFICATION The data presented in this report is a record of system measurements and final adjustments that have been obtained in accordance with the current edition of the NEBB Procedural Standards for Testing,Adjusting,and Balancing of Environmental Systems.Any variances from design quantities which exceed NEBB tolerances are noted in the Test-Adjust-Balance Report Project Summary. Warranty Project:Sunset Terrace Stairwell Pressurization Renton, WA 98056 Warranty of Services: Warranty Procedures: Voided Warranty and Additional Charges: Document Archiving An electronic file of all test documents will be kept on file until the end of the Warranty period.During that time an electronic copy of the test data will be provided a no charge.Any additional hard /bound copies requested will be subject to a fee. For all warranty items,Neudorfer Engineers requires written request.The written request should be specific on the areas of concern,such rooms,or equipment,and the type of issue the occupants are experiencing. Once written notification is received,Neudorfer Engineers will schedule a Technician.It is recommended that an Owner or A/E Representative be on site at that time. If a complaint issue is due to a mechanical equipment failure,control or maintenance related,the return trip maybe subject to a service charge,not covered under warranty.Neudorfer Engineers reserves the right to resolve any TAB issue.If a third party or competing Test &Balance Commissioning firm test or adjust any equipment,all project warranty is voided.(This is typical standard for the Mechanical industry,as Manufacture,Mechanical and Control Contractor voids all warranty when a competing firm tests or manipulates their systems.)Any return trips to the job site are subject to a service charge and a purchase order will be required before returning to the job site. Neudorfer Engineers,Inc.warrants that the air balancing,evaluated during this performance evaluation are operating at the specified levels as documented within this report.At and only this time,and makes no other warranties,stated or implied,concerning the continued performance,operation or safety in the use of this equipment past this time.Neudorfer Engineers warrants the air balancing for 1 year from the date of substantial completion.Neudorfer Engineers reserves the right to correct errors or omissions in the collections of data.
