06 Schriever AFB IFS.pdf

This solicitation is for the replacement of domestic water pumps and associated piping infrastructure at Building 420 at Schriever Air Force Base. Rather than two large pumps, the new system will utilize a combination of small, medium, and jockey pumps operating on variable frequency drives to cover a wider normal flow range of 100 to 600 gallons per minute. Three medium pumps will meet maximum daily demand plus fire flow requirements, with a fourth identical medium pump as a standby. An existing diesel fire pump will remain as a backup. The contractor will replace all steel piping in and around the building with resized pipes for the new pump flows, including new valves and fittings. A hydraulic model was created to verify pump sizing and operating points. The contractor must install a new fire department connection in an accessible location approved by the SAFB fire department.
