Columbus Air Force Base

Scope:

Recurring Maintenance, Minor Repair (RMMR) services for four buildings, one vehicle fuel island, and one awning-covered airfield vehicle fueling station. Total square footage (exteriors): 7,365

Champion’s foreman and our quality control team worked with the GC and local base leadership to match unique non-standard color requirements for the airfield fuel facility steel.

At that location, our crews used aerial lifts to access structural steel aloft for hand tool surface preparation and brush and roller application, and ensured no impact on flight operations or adjacent fueling stations.

The site was between an active runway and taxiway.

As the project neared completion, we faced the additional challenge of base access and project execution when COVID-19 restrictions were put in place. With the cooperation of Pond Constructors, base leadership, and the independent third-party QP-5 inspector, the Champion crew was able to finish the project ahead of schedule while strictly following all social distancing and hygienic guidelines.
