With a long and solid professional working history with National Steel City, CSD supported the construction during the Pittsburgh International Airport Terminal Modernization Project. The new arrivals and departures structure was built between two concourses of the existing terminal and will include the new check-in, ticketing, security and baggage operations at the Pittsburgh International Airport.

Working closely with our client, CSD designed a custom adjustable shoring tower system to provide both lateral and vertical support to the ‘tree’ column branches during erection and field welding.  The shoring tower system allowed the client to complete the extensive field welding that was required per the design, while continuing with steel erection and maintaining stability of the undulating High Roof Structure.

CSD created a three-dimensional FEA model to perform a stage construction analysis of the High Roof erection sequence. Deflections and member forces were determined from the analysis mode and verified at each stage of construction.

CSD provided a comprehensive erection plan for both the arrival/departures framing and the high roof structure, as well as custom rigging diagrams to ensure each irregular roof sub-assembly were lifted and erected in the proper orientation. CSD also developed a 3D structural analysis model and utilized it for a comprehensive staged construction analysis.
