About this file

These are federal specification documents for mechanical systems installations at federal facilities. The documents collectively govern testing, adjusting, and balancing (TAB) of HVAC systems; thermal insulation for mechanical systems; and chilled, chilled-hot, and condenser water piping systems.

Section 23 05 93 – Testing, Adjusting, and Balancing for HVAC establishes requirements for duct air leakage testing (DALT) and TAB of heating, ventilating, and cooling systems. Work must comply with AABC MN-1, NEBB Procedural Standards, or SMACNA 1780 as the base standard, with all recommendations considered mandatory. TAB specialists must submit design review reports identifying deficiencies, TAB schematic drawings with system details, and certified TAB reports with temperature data, static pressure profiles, duct traverses, instrumentation lists, and performance curves. Reports must be submitted within 21 days prior to field measurements. Submittals require government approval (designated "G"), and pressure test reports must document all phases of testing, repairs, and final results in PDF format. The contractor must furnish a one-year workmanship and performance warranty covering major deterioration or out-of-tolerance measurements, with corrective action required within seven days of notification.

Section 23 07 00 – Thermal Insulation for Mechanical Systems specifies field-applied insulation materials and installation procedures for pipes, ducts, and equipment. Materials must meet ASHRAE 90.2 requirements and include recycled content (rock wool 75%, fiberglass 20%, rigid foam 9%). Insulation systems must have flame spread index ≤25 and smoke development index ≤50 per ASTM E84. Adhesives must meet indoor air quality standards (UL 2818 Greenguard Gold or equivalent) and comply with CDPH Section 01350 or SCAQMD Rule 1168 VOC limits. Installation follows MICA National Insulation Standards plates with specific requirements for pipe hangers, vapor retarders/barriers, and protection of corners. The contractor must submit three copies of MICA plates, equipment insulation system details, and pipe insulation system shop drawings for government approval prior to installation.

Section 23 64 26 – Chilled, Chilled-Hot, and Condenser Water Piping Systems specifies piping materials, components, and installation conforming to ASME B31.9. Water piping shall be steel pipe (ASTM A53/A53M Schedule 40) or copper tubing (ASTM B88 Type L, M, or K) with ANSI/ASME Class 125 service rating (175 psig at 150°F). Connection methods vary by size: piping ≤1 inch uses threaded connections; 1–3 inches allows threaded, grooved, or welded connections; ≥3 inches requires welded or flanged connections. Valves include gate, globe, check, butterfly, ball, calibrated balancing, automatic flow control, temperature mixing, pressure relief, and drain types conforming to specified MSS standards. Installation requires pressure testing at 188 psig minimum for two hours with no leakage allowed; repairs must use rewelding or pipe replacement (caulking prohibited). Concealed and insulated piping must be tested before concealment. The contractor must provide welding procedure specifications, qualified welder certifications, and piping welds NDE reports; coordinate with TAB teams for HVAC water system balancing per Section 23 05 93. Submittals requiring government approval include grooved mechanical connections, calibrated balancing valves, water temperature regulating valves, pressure relief valves, and pressure test reports documenting all test phases and repairs.
