PDC's aviation group knows and understands FAA airport planning criteria for both large international airports, as well as small community commuter facilities. We have developed airport master plans for a number of communities within Alaska. We also have recent experience in design for major improvements projects for major civilian, and military airports. We have performed several aviation related designs and studies for state and military needs. Work includes Airport Master Plans, Environmental Assessments, airport relocation designs, overlays, taxiways, aprons paving and patching, Hardstands, gun butts, drainage master plans and extensive storm drainage system designs, oil/water separators, fire training facilities, and aircraft firefighting and rescue facilities.
