access.\nReview builders’ work requirements, equipment foundations, embedded items, sleeves, openings, trenches and service penetrations.\nVerify fire stopping and sealing of MEP penetrations through fire-rated walls, floors and compartments.\nReview piping pressure-test procedures, flushing, cleaning, disinfection, water-treatment and system-preservation requirements.\nWitness hydrostatic testing, leakage testing, duct-leakage testing, flushing, balancing and functional testing of MEP systems.\nWitness testing, adjusting and balancing of air-distribution and chilled-water systems.\nVerify operation of alarms, trips, interlocks, standby equipment, duty/standby sequencing and automatic changeover.\nReview HVAC and mechanical-system integration with BMS, fire-alarm, electrical control and emergency shutdown systems.\nReview fire and smoke-damper operation, stairwell or room pressurization and emergency-ventilation functions.\nMonitor system-performance testing against approved temperature, humidity, pressure, air-change, flow and noise requirements.\nReview equipment test certificates, inspection records, calibration certificates and commissioning documentation.\nIdentify design, installation or performance deficiencies and recommend corrective and preventive actions.\nSupport preparation and closure of punch lists, NCRs and outstanding MEP interface issues.\nReview as-built drawings, O&M manuals, spare-parts lists, training materials and preventive-maintenance requirements.\nSupport integrated system testing, reliability demonstration,
