How Modular Construction Transformed the Concourse D Expansion
Airports have long faced the challenge of expanding and modernizing facilities without disrupting daily operations. The completed widening of Concourse D demonstrated how innovative construction strategies could solve this problem while improving the passenger experience and accommodating larger aircraft.
At the center of the project was a modular construction approach designed to minimize gate downtime and maintain airport operations throughout the expansion. Instead of building directly at the concourse, the project team constructed 19 large modules at a remote site located about one mile away on the south side of the airfield. This off-site process created a safer and more controlled work environment while allowing crews to access the modules from all four sides.
The strategy delivered significant operational benefits. By reducing disruptions at active gates, the project lowered gate downtime by nearly 20 percent, generating substantial cost savings for airlines and helping airport traffic continue moving efficiently during construction.
Once completed, the modules were transported to Concourse D using a Self-Propelled Modular Transport (SPMT), a specialized vehicle capable of moving extremely heavy structures with precision. The transportation and installation process required careful planning, engineering expertise, and creative problem-solving to address the project’s unique challenges.
One of the project’s defining milestones was the successful movement and placement of the first module. According to the project team, watching the structure pivot, turn, and align perfectly over the base plates was both spectacular and rewarding, demonstrating the effectiveness of the extensive planning behind the operation.
The completed Concourse D expansion highlighted how modern construction techniques could help airports grow smarter, faster, and more efficiently while keeping travelers moving.
