After careful research, Tetra Tech determined that the Durisol wall was the best product to meet the required two-hour fire rating. In this case Tetra Tech elected to provide Durisol with the steel column layout. Durisol also has the in-house ability to design the steel columns required for thermal walls but it was decided that Tetra Tech would be better equipped to handle this portion of the scope because pile supports were required for the infrastructure at the site.
Assembly proceeded smoothly and was completed by FMI Installations with a four man crew in two days. The Durisol facing panels were first clipped over the steel columns. Panels were then lifted by a small crane and lowered between the flanges of the two steel columns.
