ACEC Recognizes Garver for Auburn Airport Project


The American Council of Engineering Companies of Alabama recently awarded Garver an Engineering Excellence Award in the Transportation category for work done on the Auburn University Airport Taxiway Extension project.



The airport extended Taxiway Charlie by 2,200 feet, including two connecting taxiways. This extension connects the Runway 36 threshold with the new terminal development area and eliminates the need for aircraft to make routine midfield crossings. However, to make this connection, the taxiway extension needed to cross a capped landfill that’s been in existence for over 25 years and contained approximately 12 feet of compressible landfill debris containing topsoil, vegetative debris, construction waste and scrap metal under a 2- to 3-foot cap of clay. This clay had to be excavated and replaced to construct a stable foundation for the taxiway extension and its associated safety area.

Garver’s engineers determined the landfill boundaries and estimated how much debris needed to be removed and replaced to get the proper base laid for the taxiway. This required 29,000 cubic yards of landfill excavation. Construction contractor D&J Enterprises of Auburn implemented a creative solution to reuse the excavated landfill material. In essence, the material was removed from the taxiway footprint and sorted. Organic soil was reused by local landscapers, trees were chipped and reused for mulch, metals were salvaged for recycling, and topsoil was reused to cap the project’s embankments. Less than 12 percent of the 29,000 cubic yards of landfill material was transported to another landfill.
