A parking area for planes at Eppley Airfield, the Cargo A / Light Cargo Apron was experiencing a level of alkali-silica reaction common in concrete of it’s age causing cracking and needing replacement. Lamp Rynearson provided a full scope of services including survey, design, and construction administration in the reconstruction of the Cargo A apron. Through boring samples, the team determined the rock and sand base courses under the concrete to still be intact and usable. 18,000 cubic yards of 14-inch concrete paving were then poured over the 940 ft by 420 ft of the apron. New storm sewers were also designed and installed during the reconstruction to handle weather events and keep the apron area free of standing water.

Phasing, an important part of all airport-related projects, was done in two parts to minimize the impact on this project. The entrance to the Cargo A apron had to be shut down and cargo planes had to use an alternate apron. Coordination among the project team and stakeholders such as UPS and FedEx was key during this reconstruction to keep shipping and sorting facilities on track during this fast-paced project schedule.
