Heavy Structures designed and supplied the structural steel for McDermott’s fabrication and assembly buildings, where they build off-shore oil and gas platforms prior to shipping the assembled platforms out to the Gulf of Mexico.
The 104,267 sq. ft. Assembly Building was built to contain two separate runways of 44 -ton top-running cranes at a top-of-rail elevation of 104', that made for a 118'-0 eave height at the low side of the single slope building. The open-ended Assembly Building was designed so the cranes could roll onto the 120' external runway system for their short trip to their sea-going transport. The 32,672 sq. ft. Sub-Assembly Building joins perpendicularly to the closed end of the Assembly Building and houses a 59'-0 tall single leg 20-ton gantry crane that is designed to allow it to travel out either end to external runways.
Shortly after completing the erection of the Assembly/Sub-Assembly structures, McDermott was ready to add other process building structures on the site that feed fabricated parts to the Assembly Buildings. Heavy Structures then supplied the 50,166 square foot Plate and Girder Shop Buildings. These structures house 20 ton and 40 ton cranes at rail heights of 61'-7" & 46'-7".
Due to the structures being open to the environment and close proximity to the gulf, all of the structurals were supplied galvanized. All the structures were clad with a 22-gauge ALZN standing seam metal roof system and 26-gauge metal wall panels.
