![]() ![]() The modernized MEM concourse opened in February. The OKC expansion opened in September 2021. Take a look at a $90 million terminal expansion at Will Rogers World Airport (OKC) and a $245 million concourse modernization at Memphis international Airport in Tennessee (MEM). ![]() While there are some universal challenges and solutions, such as creating new spaces creates new possibilities, no two solutions are exactly the same. The project site had the presence of highly expansive clay soils, so Benesch utilized the cement-treated subgrade to help mitigate the expansive soils present in the ramp expansion areas.How does an airport, through a building project, create a more pleasant passenger experience? That’s the multi-million-dollar question. The approximately 12,000 square yard ramp expansion included installation of airport safety measures, earthwork, construction of a cement-treated subgrade soil following the earthwork excavation, construction of a new P-219 aggregate base course, and construction of a new 15″ thick P-501 concrete pavement, erosion control measures, and permanent marking. Throughout the project, Benesch had to closely monitor the Contractor and the quality of the pavement materials due to constructing the pavements in late fall and winter. Benesch worked closely with Atlantic Aviation and the OKC airport to create a phasing plan that would accommodate Atlantic Aviation’s daily business needs, yet comply with current FAA safety standards. The Department of Airports liked Benesch’s approach and stated that they would even utilize some of Benesch’s safety concepts in their own AIP projects at OKC. Following the survey/geotech work, the design was then fast-tracked by Benesch and coordinated through the City of Oklahoma City Department of Airports. Benesch mobilized its own Lincoln, NE based survey and geotech crews and completed the field design topo survey and subsurface geotech investigation. The project needed to be fast-tracked to meet Atlantic Aviation’s military refueling contract obligation to provide ramp pavements for the KC-135s that operate out of the OKC airport by December 1, 2014. Atlantic Aviation hired the Tectonic/Benesch team to complete a fast-tracked parking ramp expansion project. ![]()
