About this file
This document is a technical specification section for demonstrations and tests required for boiler plant equipment and systems under Department of Veterans Affairs (VA) federal construction contracts.
The specification establishes mandatory procedures for onsite demonstration, testing, and training of boiler plant equipment prior to Government acceptance for beneficial use. Contractor responsibilities include conducting start-up activities (initial inspection, cleaning, lubrication, and adjustment), pre-tests to verify system readiness, and final tests witnessed by the Contracting Officer's Representative (COR) or designated representative. All safety devices must pass 100 percent inspection before acceptance. Equipment requiring demonstration and testing includes boilers and economizers, burners, control systems, and instrumentation. Experienced technical service personnel representing equipment manufacturers must conduct all demonstrations, instructions, and tests. The contractor must deliver maintenance and operating manuals four weeks prior to instruction, arrange for all test personnel to be continuously present during testing, furnish special tools, and correct any detected defects at no additional cost. Demonstrations and training must occur no more than four weeks prior to Government acceptance and include at least eight total instructor hours covering operation, maintenance, troubleshooting, and lockout/tagout procedures using contractor-provided written standard operating procedures. Contractors must submit certification of completed pre-testing, preliminary test schedules two weeks in advance, and final reports within three weeks of satisfactory completion, including test data and calculations. If final tests fail and require retesting, the Government receives full credit for all independent testing organization or consultant expenses incurred for re-inspections.

SECTION 23 08 11
DEMONSTRATIONS AND TESTS FOR BOILER PLANT
PART 1 - GENERAL
1.1 DESCRIPTION
A. Procedures for onsite demonstration and testing of equipment and systems, including temporary facilities.
B. Instruction of Government operating personnel.
C. All demonstrations, instructions, access platforms, and testing must be completed prior to Government acceptance for beneficial use. All safety devices shall pass 100 percent before the boiler plant can be accepted for beneficial use.
D. Plumbing and emergency power systems are not included.
E. Definitions:
1. Start-Up: Initial inspection, cleaning, lubrication, adjustment, and operation of equipment and systems by the contractor with the assistance of the representatives of the equipment manufacturers.
2. Pre-Tests: The final stage of the start-up procedure. This occurs after all adjustments have been made except for minor fine-tuning that can be done during the pre-test. Serves as verification that the systems are ready for the final test. Witnessing of pre-test by
COR is not required.
3. Final Tests: Tests, witnessed by the COR or designated representative, which demonstrate that all equipment and systems are in compliance with requirements. At VA expense, VA may utilize the services of an independent testing organization or consultant to witness the tests. If any portion of the final test fail and must be retested the Government shall receive a full credit for any expenses incurred for services from independent testing organizations or consultant services for all re-inspections or tests.
F. A complete listing of common acronyms and abbreviations are included in Section 23 05 10, COMMON WORK RESULTS FOR BOILER PLANT AND STEAM
GENERATION.
1.2 RELATED WORK
A. Section 23 05 10, COMMON WORK RESULTS FOR BOILER PLANT AND STEAM
GENERATION.
B. Section 23 09 11, INSTRUMENTATION AND CONTROL FOR BOILER PLANT.
C. Section 23 52 33, WATER-TUBE BOILERS.
