Ramtech recently announced the completion a 16,800 square foot permanent modular office building for Cameron LNG. The new facility is located at Cameron’s liquefied natural gas terminal site along the Calcasieu Channel in Hackberry, Louisiana. The design-build project was built using our Accelerated Building System (ABS) prefabricated construction method, a proprietary system which allows for the rapid installation of factory-built modules which are a fixed directly onto a conventional concrete slab foundation. The Type V-B blast resistant building features individual private offices that use a glass interior storefront partition system around the perimeter of the interior and a large L-shaped clear span office area for multiple cubicles. There are also two large training and conference rooms, and a separate crew room and locker storage area.
The design criteria for the modular building required meeting a 170 mph Exposure D wind load, Seismic Category A, and .54 psi Blast Overpressure rating which placed a unique demand on the building’s structural system. O.S.B. sheathing was installed on both sides of the six-inch exterior steel studs, with the roof incorporating 2 x 10 wood framing and plywood sheathing supported by open web steel trusses attached to structural steel tube columns that are welded to 1” thick steel plates embedded and anchored into the 4,000 psi concrete slab foundation with reinforced grade beams. To accommodate the Gulf Coast areas high humidity while accounting for the outside air intake requirements for the building’s occupants, Ramtech installed Lennox roof mounted HVAC units. The buildings exterior is wrapped in standard R-Panel metal siding. Ramtech completed the $3.2 million project in 165 days.
