This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. Simplified Acquisition Procedures will be used. The Naval Surface Warfare Center, Dahlgren Division, intends to procure on a full and open competition basis the following items: CLIN 0001- A quantity of 1 each Temperature and Humidity test Chamber in accordance with the following statement of work: SECTION C - DESCRIPTION/SPECIFICATIONS/ WORK STATEMENT C.0The contractor shall deliver and install a temperature and humidity chamber at NSWCDD Explosive Experimental Area, Dahlgren, Virginia. The chamber shall meet the requirements outlined in this statement of work. DESIGN REQUIREMENTC.1CHAMBER CONSTRUCTION: C.1.1 The maximum exterior chamber dimensions are 44-ft long and 10-ft wide. The chamber walls and ceiling shall be designed to maximize internal volume yet provide sufficient insulations for the required temperature range. The chamber must be capable of being placed inside building 9462 (dimensions are 40 feet x 50 feet 4 inches) without any physical change to the building shell. Vendor proposals shall include a drawing of the proposed chamber layout including access doors, movable partitions and machinery sections. C.1.2 The chamber may be constructed with welded or prefabricated panels. Interior walls and ceilings shall be at least 22 gauge stainless steel. Exterior walls shall be aluminum, stainless steel or epoxy painted steel. Wood shall not be used in the wall, ceiling or floor panels. C.1.3 Chamber thermal insulation shall be a minimum of 4-in of urethane foam in walls, ceiling and floor. Other insulation materials may be proposed if they provide the same or better performance over the temperature and humidity operating range of the chamber.C.1.4 The chamber floor structure shall be constructed to support a 7,000 lb/sq-ft live load. The floor surface shall be stainless steel plate a minimum of 12 gauge. The government will modify Building 9462 with a recessed concrete slab to accommodate the chamber floor structure. C.1.5 all chamber access doors shall be a minimum of 60-inches wide by 78 inches high.
