Century West, acting as the Redmond Airport’s Civil Engineering Consultant, provided design and construction engineering services for a new runway surface that will meet the needs of the airport for the next 20+ years. In addition to restoring the runway surface’s useful life, Century West’s approach aimed to minimize the impact to commercial airline operations during construction and correctly phased the project to match anticipated available funding.
Specifically, the project required reconstruction of the intersection of Runway 4-22 and Runway 10-28, which, in turn, required the temporary complete closure of the airport during construction. After consulting with contractors, the airport, the airlines, and other engineers, Century West developed a collaborative approach that minimized impact, airport closures, and airline delays during construction. In addition to the runway reconstruction, the airport’s high intensity runway lights (HIRL) system was replaced, and the FAA NAVAIDS were relocated and adjusted.
Due to changes in FAA design standards between the project planning phase and initial design phase, overall project costs nearly doubled. In its original concept, the project was to be a basic grind-and-overlay project to simply restore the runway’s wearing surface. However, design standard changes necessitated converting the runway cross section from a “shed” section to a “crowned” section and also required improvements to the runway profile to ensure conformance with ADG C-III standards. These changes had a domino effect that required replacement of the runway HIRL system and extensive runway safety area grading.
To make the project economically feasible, Century West proposed multi-year project phasing over two construction seasons, that allowed the FAA to fund the project in manageable pieces. The project was funded through the FAA’s AIP program and state funds through the Connect Oregon program. The funding combination was coordinated such that the Airport will have zero out-of-pocket costs for the improvements.
