11 Foundation Drawing - GLEN 12-1027.pdf

This federal contract opportunity solicitation seeks replacement of domestic water pumps and piping infrastructure at Building 420 on Space Force Base Glen. Rather than two large pumps, the project will install three medium pumps and one standby pump on variable frequency drives to provide a wider normal flow range of 100 to 600 gallons per minute, meeting maximum daily demand plus fire flow with all three medium pumps running in parallel. The contractor must replace all steel piping in and around the building with resized pipes per the new pump flows and install new valves and fittings. A hydraulic model was used to verify pump head and turndown requirements at required flows. The distribution pressure target is 84 psi for normal flow and 110 psi for fire flow. The contractor must also install a new fire department connection in an accessible location approved by the base fire department, consisting of two 2-inch connections with NH threaded swivels per NFPA 1963 standards. The solicitation is issued by the Department of the Air Force Space Command.
