This document contains mechanical schedules and HVAC system design drawings for a seismic deficiency remediation project at the VA SCI & CLC Hospital in San Diego, California.

The project involves comprehensive mechanical systems upgrades including air handling units (AHUs), terminal units (TUs), fan coil units (FCUs), cooling towers, chilled water systems, hot water systems, steam distribution, and associated controls and accessories. Key equipment specifications across multiple schedules include AHUs ranging from 5,000 to 22,000 CFM capacity, numerous terminal units for zone-level conditioning, and expansion/flash tanks for pressurized systems. The drawings detail supply and return air ductwork routing across multiple building levels (1st through 4th floors plus penthouse and roof), mechanical shaft locations, and chilled water supply/return (CHS/CHR) and hot water supply/return (HWS/HWR) piping throughout the facility's north and south wings. Steam piping diagrams specify medium pressure steam (MPS) at 30 PSIG distribution with various steam traps, condensate return systems, and a clean steam generator. The schedules include equipment locations, airflow ratings in CFM, capacity specifications in GPM for water systems, control valve requirements, and miscellaneous accessories such as dampers, filters, and strainers. All systems are designed for operational access and maintenance by personnel at floor level without portable ladders. The project is prepared by CannonDesign (Architect/Engineers) with consulting by ITG, and was conformed as of October 31, 2020, with mechanical engineer Paul Q. Ping Dong (Professional Engineer License No. M029768).
