About this file
These are mechanical design drawings for the renovation of Building 1, First Floor at VA Central California Health Care System in Fresno, California. The project involves designing an Acute Respiratory Clinic with specific HVAC, piping, and controls requirements.
The drawings document the mechanical systems design including: (1) First Floor Mechanical Pressure Relationships (Drawing MH-107) showing room pressure requirements ranging from negative 10 ACH (air changes per hour) for soiled hold and hazardous areas to positive 4 ACH for exam and interview rooms, with CFM (cubic feet per minute) values specified for supply and exhaust air; (2) First Floor Mechanical CHW Piping Demo Plan (MP-101) indicating demolition of existing duct coil B-16 and evaporator with associated piping to be capped and sealed, and rerouting of chilled water lines to maintain service to floors above and below; (3) First Floor Mechanical Piping Plan (MP-102) showing new chilled water piping installation with 3/4-inch and 1-inch diameter lines, isolation valves at connection points, and controls network integration with existing JCI control systems; and (4) First Floor Mechanical CHW Piping New Plan (MP-102 continued) detailing hot water supply and return lines from a 2-1/2-inch SPS riser routed from the pharmacy area. Key requirements include infection control and risk assessment (ICRA) protocols, coordination with existing conditions, field verification of routing, phased construction to minimize operational impact, room pressure monitoring between exam rooms and corridors with alarms set for positive pressure exceeding 5 minutes, and weekend/extended hours work to maintain service continuity. The design is dated 04/07/2026 with Bulletin No. 2 revision dated 06/18/2026.
