Y -- SUBMILLIMETER ARRAY FACILITY SOL IFB519-2-95 DUE 050295 POC Contracting Officer, George D. Dick, 617/495-7401, FAX 617/496-7692 The project consists of constructing a major portion of the summit facilities for the Smithsonian Submillimeter Array Facility on Mauna Kea, Hawaii. The construction consists of two (2) prefabricated steel frame buildings: a 15m x 15m x 14m (50 x 50 x 47 ft) antenna assembly facility with a 7m x 10m rollup door, lighting and ventilation systems and with provision for a 30-ton overhead crane (the crane is customer supplied and installed); and a smaller, 8m x 7m, auxiliary generator building. Construction includes three building foundations, the two prefabricated steel buildings mentioned above and the foundations for one prefabricated modular building (to be purchased later) along with the associated sidewalks, access ramps and stairs. The building infrastructure also includes: a complex electrical system with twenty seven (27) 480 VAC circuits; water and septic systems; a ten-car, paved parking lot; and connection to the local utility systems. The site preparation includes the installation, on the nearby terrain, of twenty one (21) similar concrete antenna foundations, each containing about 75 cubic yds of reinforced concrete. The antenna foundations will be connected via 1975m of graded pathways and 1975m of 1-meter-deep trenches containing conduits and electrical power cables to be installed by the contractor. The project is located at the 4045m (13,350 ft) elevation of Mauna Kea on the island of Hawaii in an area known locally as Millimeter Valley. The site is approximately 72km from the city of Hilo. All prospective bidders are required to attend a Bidders Conference and Site Inspection tentatively scheduled for 4/14/95. Call (808) 969-1551 for details. The estimated cost of the proposed construction is between $1,000,000 and $5,000,000. Requests for IFB should be requested in writing only. No telephone requests for the solicitation package will be accepted. (0054)
