(heat transfer) capabilities are unknown at this time but shall be determined with and approved in writing by the VA COR prior to ordering. The Contractor is responsible to ensure that all work is done to the satisfaction of VA Maintenance Staff. The following coil dimensions are approximate to allow the Contractor to develop a firm, fixed-price, cost proposal for performance of the complete repair. Contractor to verify and determine precise dimensions, working pressures, and heat transfer capabilities. Coils shall be mounted on hot dipped galvanized steel supports to assure proper anchoring of coil and longevity and future maintenance. Coils shall be face- or side-removable for future replacement through the existing access doors, or removable panels. Each coil should be installed so that it is removable without disturbing adjacent coil. Cooling coils shall be designed and installed to avoid condensate carryover. Contractor is to Provide factory installed extended supply, return, drain, and vent piping connections. The period of performance for this project will be 45 calendar days. Contractor shall attend site visit before submitting proposal to Contracting Officer. Chilled Water Cooling Coils (8-Row, 5/8 diameter) (1-each)23-inches x 108-inches x 16-inches (1-each)48-inches x 108-inches x 16-inches Steam Heating Coils (1-1/8 diameter) (1-each)23-inches x 108-inches x 5-inches (1-each)48-inches x 108-inches x 5-inches steam trap size and type, adequate static leg for the gravity drain, and the recommended slope for the gravity return. (b) Hot Water Coils With Glycol: Select hot water or glycol preheat coils where the preheat coil surface comes in contact with 32 F [0 C], as defined above, or lower air temperature. Use propylene glycol solution with corrosion inhibitors specifically manufactured for HVAC applications. See Chapter 4 for glycol properties and design criteria. Hot Water Coils Without Glycol: Glycol can be omitted where the heating design temperature is above 32 F [0 C]. The following freeze protection measures are recommended: Provide a dedicated circulating pump in the coil circuit with hydronic separation between the coil circuit and the incoming hot water piping to maintain a constant water velocity of 3.0 fps [0.9 m/s] through the coil tubes. See VA Standard Detail Preheat Coil (Hot Water) Piping Connections. http://www.cfm.va.gov/til/sDetail/Div23HVACSteam/SD238216-02.pdf Select coils with wider fin spacing to reduce pressure drop. Provide coil connections to ensure that the coldest air faces the hottest fluid. Electric Coils: Electric preheat coils may be used where steam and/or heating hot water are not available. Select low-watt density electric coils complete with UL safety devices and Silicon Controlled Rectifier (SCR) controls for modulating operation. Refer to Chapter 4 Section 4.4 Heating Systems for additional information regarding the use of electric heat 3.2.2.11 Unit-Mounted Reheat Coils Air-handling unit mounted reheat coils are used for single-zone application and elsewhere where required. Hot water or steam coils with modulating control valves are the preferred choice. Electric reheat coil may be used where hot water or steam is not available. Refer to Chapter 4 Section 4.4 Heating Systems for additional information regarding the use of electric heat.
