Modify Vehicle Assembly Building High Bay-3 Platforms for Block 1B   4

Contractor shall provide the necessary resources to fabricate and erect new platforms in the Vehicle Assembly Building (VAB). Each of these platforms weigh approximately 300kips, and consist of W44 rail beams that support a welded steel structure (approximately 38ft by 60ft) that can move along the length of the W44s, the mechanical, electrical, and control systems that drive the platform movement, as well as lighting, communications wiring, and fire suppression systems that support the operations and emergency egress. The W44's will be welded to a large machined corbel structure, which attaches to a track system on the facility columns, by a set of 4-inch diameter pins. In addition, new floors and rooms, walls and ceilings will be constructed in the building. Other ancillary work on building system modification/extension is included for the following: fire suppression pipes and valves, fire alarm, gaseous Nitrogen and gaseous Helium tubing (>5,000psi), and electrical power. The VAB is a greater than 500ft tall steel frame structure with a cavernous interior: all of the above installation scope will be completed at heights ranging from about 280ft to about 450ft above ground, requiring extensive experience with personnel access, material delivery, and fit up/ bolting/ welding materials at such heights. This is an operational facility and construction will be completed in the operational downtime between launches, and dual occupancy of the work space is anticipated.

NOTE: Due to specification and drawing file sizes, Specification 79K40462 is split into 2 files and Drawings 79K40461, Vol 1 is split into 4 files to fit within the SAM.gov file size limitations.
