Vandenberg Crane Replacement

The Department of the Air Force Sustainment Center seeks engineering, fabrication, installation, testing, and commissioning of a replacement overhead crane system at Vandenberg Space Force Base Building 9320, with proposals due November 23 and a mandatory site visit on October 28. The procurement is a Total Small Business set-aside.

Place of performance is Lompoc, California, during normal hours Monday through Thursday 0600–1630, excluding federal holidays. The new system comprises one under-running single-girder bridge crane rated for 4-ton capacity, CMAA Class D service; two independently operated 2-ton capacity electric wire rope hoists on trolleys with integrated controls; variable frequency drives; pendant and backup radio remote controls; emergency stop and overload protection; and dual-reeved configuration with equalizer sheaves and micro-speed positioning at 25 percent nominal speed. Bridge end trucks operate at 95 FPM with AC motor brakes and manual hand-release. The system must meet ASME HST-4 H4 duty classification, seismic design per SSCMAN 91-710, and electrical requirements of 460 VAC, 3-phase, 60 Hz with NEMA Type 12 steel control enclosures and fail-safe hardwired emergency stop circuits. Hoist nominal speeds are 15 FPM for hoists and 50 FPM for trolleys.

The contractor must perform proof-load testing at 125 percent of rated capacity with nondestructive examination on safety-critical welds and components, provide Commercial Operation and Maintenance Manuals, PE-stamped structural and electrical drawings, spare parts list, test plans, final test report with crane certification, preventive maintenance plan, integrated master schedule with monthly updates, and site-specific safety plan addressing lockout/tagout, fall protection, electrical safety per AFMAN 91-203, and hot work operations. All submissions deliver to four Government addressees in Microsoft Office compatible format. NAICS code is 333923, Overhead Traveling Crane, Hoist, and Monorail System Manufacturing; PSC code is 3950, Winches, Hoists, Cranes, and Derricks. Minimum one-year comprehensive warranty is required.
