Gerald R. Ford International Apron Reconstruction

C&S designed and performed construction administration and observation for the reconstruction of the deteriorated 150,000-square-yard air carrier apron pavement and infrastructure at Gerald R. Ford International Airport. Components include new PCC pavement and asphalt shoulders, utility improvements, including water main and sanitary sewer, new drainage system and infrastructure for collection and disposal of deicing glycol, and terminal area lighting. The pavement geometry adjacent to the concourses was evaluated allocate space for parked aircraft and aircraft movement around the ends of each concourse and alternatives were prepared. C&S used 3D modeling to develop several concepts to improve overall drainage and glycol collection. The apron pavement is graded and a glycol collection system includes a separate apron drainage system and multiple underground tanks outside the apron pavement. C&S also integrated sustainability, conducting a charrette to collaboratively determine options for enhancing economic considerations, airfield operations, natural systems, and society. Through this process several unique and unconventional approaches emerged. Construction phasing was a significant challenge because the airport could not afford to close several gates concurrently. C&S prepared multiple alternatives to minimize impact to aircraft and gate operations. With numerous constraints and the project’s scale, the final phasing plan included seven phases over two years.
