The Salt Lake City International Airport, a civil-military airport operated and managed by the Salt Lake City Department of Airports, is the 21st busiest airport in passenger count in the US. It is one of the largest hubs for Delta airlines, hub for SkyWest Airlines, Southwest Airlines, American Airlines and Alaska Airlines. The airport has 3 terminals with 5 concourses with a total of 83 gates.
The Salt Lake City Terminal Redevelopment program replaces the existing concourses with two linear concourses (North and South Concourse) connected by a passenger tunnel. The project will be built in two phases to be completed in 2020 (Gateway Center, Parking Garage, Terminal, North and South Concourses - West) and 2024 (North and South Concourse - East).
PDC’s scope of work with ADF included the 3D BIM modelling and shop detailing of 16,000 tons of structural steel of the terminal, south concourse west and south concourse east.
PDC also worked with Schuff on 3D BIM modelling and shop detailing of 1,800 tons of structural steel work on the parking garage and central utility plant (CUP).
The Salt Lake City Airport project is a very significant project for PDC with an annual passenger traffic of nearly 23 million people, with current facilities that are over 50 years old and designed for half that many passengers.
The Project is located on the West Coast of the US in an area of high seismic risk and as a result the connections are Engineer mandated under strict criteria.
Garage structure is 900 feet long. There are approx. 330 No 120 foot long lattice trusses in the roof to co-ordinate connection details for Seismic stability by bolted moment connections.
The cup building contains Buckling Restrained Braces due to seismic stability requirements which required co-ordination with the brace manufacturer to ensure gusset plates and welds were the correct size and also that the manufacturing dimensions provided did not cause problems.
Potentially solar panels being introduced on the roof which would result in around 2500 additional support beams between lattice trusses.
