Construction at the modular yard was one mile from the final placement location for the Concourse D modular units.
Modular units were dressed with cameras and test placements were conducted to ensure that the 710-ton units could be successfully loaded on the self-propelled modular transport with minimal deflection.
Modular units prepare on self- propelled modular transport for overnight move and placement.

Hartsfield-Jackson Atlanta International Airport ATLNext Concourse D Modular Construction (Phase 1) WSP
Project Location: Atlanta, Georgia Project Start Date: January 2024 Project Completion: September 2024
Building Information Modeling and precision surveying were critical for clash detection and correction of and mechanical, electrical, plumbing, fire protection, security and technology systems rough-ins conducted on the Mod Yard.
Modular units were moved one mile from the mod yard across runways and taxiways between one and four AM in careful coordination with the airport control tower.
Atlanta’s Hartsfield-Jackson Airport Begins Concourse D Upgrade
ATL Concourse D Widening | ATLNext
Project Team: WSP, H.J. Russell & Company and Turner & Townsend Heery (Joint Venture), CM Support Services - ATL Construction Management Partners (ACMP JV), Design - Corgan-Goode Van Slyke (C-GVS JV), Construction Management At-Risk - Holder-Moody-Bryson-Sovereign (HMBS JV), Planning Services - Ricondo-TCE JV Project Background: Hartsfield-Jackson Atlanta International Airport (HJAIA) is putting the “mod” in modern construction by building and transporting large modular units to expand and revitalize Concourse D at the world’s busiest airport which serves over 100 million passengers per year. The $1.4 billion project involves moving 19 modular units at 1:00 a.m. from a mile away and crossing two runways. The project is aimed at increasing the narrow, 44-year-old Concourse D’s footprint, the smallest of the airport’s # concourses, by widening it from 60 feet to 99 feet and extending its overall length by 288 feet to accommodate today’s larger aircraft and enhancing the passenger experience. The project is a complex combination of modular and traditional construction that minimizes airport disruptions and accelerates the project timeline. Impact: The project sought solutions that yielded community and environment benefits, while minimizing detrimental impacts. The design team considered safety, sustainability, user education, and community needs during project development. The slower roundabout speeds combined with greatly reduced traffic volumes made a roundabout the ideal design for the Chisholm Trail intersection near Round Rock High School. It is now a much safer and less congested intersection for both pedestrian and vehicular traffic. Self-contained treatment units for water quality management were provided for environmental protection of the outfall and the environmentally sensitive Edwards Aquifer and potential habitat of threatened and endangered species. Although roundabouts have recently gained popularity within the region, they were not common during the design phase 10 years ago. Halff produced a computer-generated, first-person drive-through video of the proposed overpass and roundabout, including narration, to educate the public on the project and how to navigate it.
The self-propelled modular transporters aligned and placed the modules on new foundations parallel to existing concourse D with accuracy within 1/16 of an inch.

Completed and expanded gate waiting area. When fully completed Concourse D will have 34 new aircraft designed Group III gates that accommodate larger aircraft and provide 20% more seating at peak period.
Phase 7 - modular units in use. When all modules are placed Concourse D will we widened from 60 to 99 feet and extended 288 feet.
