REPLACE HVAC SYSTEM AT CAD-564 CAX, VA

FSRM Special project ST23-0798 • Brief Scope: Replace 40 ton DX condenser, 13,000 CFM AHU, .28 KW fan 10KW heating VAV units, 10 ton Computer room A/C system: If system is not replaced soon the components will fail leaving creating large areas of the building excessively hot or cold depending on season. If the computer room system should fail the command mission would be impacted by forcing a shutdown of server that maintains database for all transactions. • Estimated Cost: • Affected sqft: 15,550 • Builder FCI :51 • Execution Agent: NAVFAC • Acquisition Method: D/B • Design Funds Required: N/A • Date of last major renovation: N/A The VAV units and several parts of the HVAC system are original to the building and some components are no longer parts supported. As VAV units fail dampers have to be manually adjusted which decreases the efficiency of the system by taking more or less cubic feet of air to cool space than the exact amount that dampers controlled by the DDC system. • This project replaces the main 40 ton DX system and the 10 ton system that cools the server room. – Twenty six year old computer room Heating Ventilation Air Conditioning System beyond useful life – Twenty six year old VAV units and associated components; beyond useful life – Sixteen year old AHU and DX compressor at end of useful life If system is not replaced soon the components will fail leaving creating large areas of the building excessively hot or cold depending on season. If the computer room system should fail the command mission would be impacted by forcing a shutdown of server that maintains database for all command transactions.
