The project included the construction of paved shoulders (approximately 39,000 square yards) along Runway 4R-22L, removal and remarking of runway pavement edge markings, isolated concrete pavement repairs, and modifications to the existing runway edge lighting system. Concrete and asphalt pavement bid options were evaluated using a Life-cycle Cost Analysis, and asphalt shoulders were elected to be constructed.
KEY Engineering Group, Inc. (KEY) was responsible for the electrical design services and construction phase services associated with the project.KEY designed a high-intensity runway edge lighting system utilizing telescoping bases in the non-active paved shoulders and load-bearing full-depth bases for the in-pavement high-intensity runway edge lights in the active pavement. The design included a conduit system with cable routed to the airfield lighting vault. Two circuits were designed, which utilized the interleaving of the circuits and two new constant current regulators.
