McKim & Creed partnered with Derr & Isbell Construction to provide heavy construction survey layout for the South Canopy, one of two monolithic arched structures that are part of a $6-billion improvement project at Hartsfield-Jackson Atlanta International Airport.
The North and South Canopies span eight traffic lanes and enhance passenger experience by providing shelter from the elements and improving traffic flow with elevated walkways. According to an article in the Dixie Contractor, each of the monolithic arched canopies is 72 feet tall at its apex, 194 feet wide and 864 feet long. Combined, the canopies contain 3,500 tons of domestically sourced steel (the equivalent weight of nine Boeing 777 jets) and are covered in 19,776 square yards of lightweight ethylene tetrafluoroethylene (ETFE) panels embedded with more than 3,500 customizable LED strip fixtures for nighttime illumination.
McKim & Creed provided initial layout and quality control check (as-builts) of the steel in the nearby laydown yard. Each steel piece had a very specific, pre-determined shape and size. McKim & Creed was tasked with comparing the design dimensions versus the actual constructed steel piece. We also provided quality control checks and layout as the beams are placed on the terminal roof.
To provide these services, crews were required to be Security Identification Display Area (SIDA) badged for the roof steel placement.
The Canopies were part of a $6-billion master plan to modernize the Central Passenger Terminal Complex, extend two concourses, build multiple parking decks, add a new runway and expand cargo facilities.
