The bolt-on steel truss addition consisted of 8”x8” I-beam that attached at the existing purlin locations. Signature designed a custom bolt-on steel system that attaches to the existing truss and allows for the integration of the new membrane. Though the plan required significant design efforts and a long term construction strategy, Signature met the requirements of the Chickasaw Tribe and developed a solution that allowed for 540 tons of steel to be raised without having to close the casino doors, a first in the industry. Following a strict safety plan, Signature devised a method that allowed the new addition to be completed without hindering day to day operations. It was critical that the casino not be shut down during the upgrade process. Signature was responsible for the entire upgrade from design to installation and factored in the tribe’s concerns and requirements. The package was completed with revised calculations, stamped drawings and a warranty of the work performed. The upgrade package consisted of steel I-beam, I-beam attachment system, new membrane, membrane attachment system, additional door and vent framing, door hood additions and drainage control. Signature’s code compliance review, which includes structural analysis, revealed that steel would need to be added to the structural members to meet the new codes and provide increased collateral loading.
