Atlanta International Airport Concourse D Widening - Innovation on the Move
When Hartsfield-Jackson Atlanta International Airport wanted to modernize and expand one of their most cramped concourses, they looked at numerous schemes. Their goals were simple: increase overall passenger capacity for the concourse, bring the existing building in line with modern building codes (it was built in the 1970s), and do that all with the least amount of disruption to airport operations. The Design, Construction, and Ownership teams collectively decided to implement a bold approach: modularize the building, build as much of it outside the airport security fence, and then move the completed structures to their final locations. Collaboration was the key to success for this project, and we will be discussing how the Engineers of Record and the Structural Steel Team worked seamlessly together to solve problems and get the project to the finish line utilizing the Advanced Project Delivery process. We will discuss the design process with a special focus on the design criteria based on temporary conditions, including those imposed during the module moves. Finally, we will share photos of the partially completed project.
Learning Objectives
- What considerations go into deciding whether modular construction is the right solution for a project.
- What special design criteria need to be considered when doing modular construction and transporting a completed structure to it’s final location.
- What are the advantages of the APD process and best practices.
