Written by GovTribe AI · Sep 15, 2026

This is a mechanical drawing cover sheet and technical specifications document for the Historic Courthouse Renovation project in Centreville, Maryland, prepared by Torchio Architects for Queen Anne's County. The document establishes comprehensive mechanical installation requirements and standards for the complete HVAC system renovation of the 17,800-square-foot dormant courthouse building. The project includes demolition of 1960s-era HVAC and electrical systems, with new mechanical systems comprising multiple variable refrigerant flow (VRF) units, both ducted and ductless mini-split units, energy recovery ventilators, and an integrated control system. The drawing set includes detailed mechanical notes, abbreviations, legends, and symbols to guide contractor installation, coordination with other trades, and compliance with applicable building codes.

The specifications detail extensive technical requirements for refrigerant piping installation compliant with ASHRAE 15-2022, including pipe protection standards, prohibited installation locations, brazing and soldering specifications, hanger and support requirements, and refrigerant equipment installation protocols. Testing and inspection requirements mandate engagement of a qualified testing agency to perform strength tests using inert gases and leakage tests with specific vacuum and pressure parameters before system operation. All refrigeration systems containing 55 pounds or more of refrigerant require a certificate of test issued by the installing contractor and signed verification documenting test dates, pressures, refrigerant designation, and test medium. The document emphasizes contractor responsibility for coordinating all mechanical work with plumbing, electrical, and other trades; determining exact existing utility locations; and obtaining approval from the Contracting Officer Representative before proceeding with work when site conditions prevent execution as indicated on drawings.

SEPARATE TESTS FOR ISOLATED PORTIONS OF THE SYSTEM ARE PERMITTED, PROVIDED THAT ALL REQUIRED PORTIONS ARE TESTED AT LEAST ONCE. PRESSURIZE WITH TEST GAS FOR A MINIMUM OF 10 MINUTES TO NOT LESS THAN THE LOWER OF (A) THE LOWEST DESIGN PRESSURE FOR ANY SYSTEM COMPONENT OR (B) THE LOWEST VALUE OF SET PRESSURE FOR ANY PRESSURE RELIEF DEVICES IN THE SYSTEM. THE DESIGN PRESSURES FOR DETERMINATION OF TEST PRESSURE SHALL BE THE PRESSURE IDENTIFIED ON THE LABEL NAMEPLATE OF THE CONDENSING UNIT, COMPRESSOR, COMPRESSOR UNIT, PRESSURE VESSEL OR OTHER SYSTEM COMPONENT WITH A NAMEPLATE. A PASSING TEST RESULT SHALL HAVE NO RUPTURE OR STRUCTURAL FAILURE OF ANY SYSTEM COMPONENT OR REFRIGERANT PIPING. PRESSURE RELIEF DEVICES MAY NEED TO BE TEMPORARILY REMOVED AND REPLACED WITH PLUGS

DURING THE STRENGTH TEST.

F. LEAKAGE TEST. THE LEAK TEST SHALL BE IN ACCORDANCE WITH ASHRAE STANDARD 147, ASME B31.5, OR THIS SECTION.

1) LEAK TESTING PROTOCOL. AFTER THE TIME TO COMPLETE THE STRENGTH TEST, CONTINUE TO PRESSURE TEST IN ACCORDANCE WITH PIPING SYSTEM STRENGTH TEST ABOVE FOR A MINIMUM PERIOD AS SPECIFIED IN THE FOLLOWING TABLE, DURATION OF LEAK TEST. THE SYSTEM SHALL SHOW NO LOSS IN PRESSURE ON THE PRESSURE MEASURING DEVICE DURING THE PRESSURE TEST. CALCULATION OF THE PRESSURE DIFFERENTIAL BASED ON A CHANGE IN AMBIENT TEMPERATURE SHALL BE PERMITTED. A VACUUM OF 0.0097 PSI ABSOLUTE OR LOWER SHALL BE ACHIEVED. AFTER ACHIEVING A VACUUM, THE SYSTEM SHALL BE ISOLATED FROM THE VACUUM PUMP. THE SYSTEM PRESSURE SHALL NOT RISE ABOVE 0.029 PSI ABSOLUTE FOR A MINIMUM PERIOD AS SPECIFIED IN THE FOLLOWING TABLE, DURATION OF LEAK TEST. THE VACUUM PUMP SHOULD GRADUALLY CREATE A

VACUUM TO AVOID FREEZING OF ANY MOISTURE IN THE PIPING SYSTEM.

DURATION OF LEAK TEST

NOTE: THE MAXIMUM PIPE SIZE IS THE LARGEST INTERCONNECTING FIELD PIPING INSTALLED.

G. CONTRACTOR DECLARATION. THE INSTALLING CONTRACTOR SHALL ISSUE A CERTIFICATE OF TEST, VERIFYING STRENGTH TEST IN ACCORDANCE WITH PIPING SYSTEM STRENGTH TEST, AND LEAKAGE TEST IN ACCORDANCE WITH LEAKAGE TEST, TO THE AHJ FOR ALL SYSTEMS CONTAINING 55 LB OR MORE OF REFRIGERANT. THE CERTIFICATE SHALL GIVE THE TEST DATE, PHOTOGRAPH OF THE PRESSURE GAGE AT THE TEST PRESSURE, REFRIGERANT DESIGNATION, TEST MEDIUM, AND THE FIELD TEST PRESSURE APPLIED TO THE HIGH SIDE AND THE LOW SIDE OF THE SYSTEM. THE CERTIFICATION OF TEST SHALL BE SIGNED BY THE INSTALLING CONTRACTOR AND SHALL BE MADE PART OF THE PUBLIC RECORD.
