Apron Rehabilitation
With its start as a WWII training field, San Angelo Regional Airport-Mathis Field has evolved into a primary non-hub facility serving 60,000 annual passengers. Numerous improvements have been made through the years, but the original 3,600 by 600-foot concrete apron had not been addressed.
The City of San Angelo selected Garver as its Engineer-of-Record. The apron suffered numerous pavement failures, and Garver designed a rehabilitation/reconstruction with a limited budget. Project funding was uncertain given the FAA's lapsed re-authorization. The project began with a budget of $500,000.
Shortly before the bid advertisement, an additional $2.5 million became available. In less than three weeks, Garver expanded the design to a full-depth reconstruction to capitalize on the additional funding. The project advertized as a 21,000-square-yard reconstruction of the 6-inch concrete apron. The new section consisted of 14-inch concrete constructed on a cement-treated base course.
Another $500,000 became available during the advertisement. Garver fast-tracked the design of an additional 4,000 square yards of apron reconstruction and added it to the project prior to the bid opening.
The reconstruction widened the heavy duty air-carrier apron serving American Eagle, Continental Express, and 737 charters. The reconstruction also included a 220 by 660-foot section in front of the AMCOM hangar where AH-1 Apache helicopters are refurbished after returning from overseas. Much of the construction was completed during overnight hours given the high summertime temperatures and to accommodate the airlines.
Taxiway Bravo Rehabilitation
Garver is currently designing a rehabilitation of the parallel taxiway for Runway 18-36. The project consists of the rehabilitation of Taxiway Bravo and the associated exit taxiways Charlie, Delta, Echo, and Foxtrot. The design includes milling and removing 1-2 inches of the existing asphalt surface course, followed by the placement of a new 2-3-inch asphalt surface course.
