Project cost


Century West recently completed design and construction services for all phases of the Hillsboro Airport (HIO) Runway 13R/31L Rehabilitation project, which consisted of the reconstruction of a 100-foot keel section of the runway for roughly 2/3 of the length of the runway, a stepped mill and inlay of the outer 25 feet of the runway, and a two-inch overlay of the southern third. The project also included shoulder reconstruction and widening, electrical and signage improvements, grading and drainage improvements, the replacement of the runway subdrain system, and pavement markings. Electrical/signage and pavement marking work spanned the full length of the runway and required the shut-down of the cross-wind Runway 2/20 for a short duration. Significant stakeholder coordination was necessary to help facilitate Port discussions with Airport tenants and Air Traffic Control to identify a viable construction plan. Century West coordinated with HIO operations staff to find a solution for phasing construction work in a manner that would minimize the Runway 2/20 shutdown schedule and overall impacts to airport operations. The civil design, project specifications, FAA Design Report, Construction Safety and Phasing plans and narrative, and City of Hillsboro and Clean Water Services permitting were all completed by Century West under this contract.

The original plan for the project was to complete reconstruction of two-thirds of the runway during the 2019 construction season and overlay of the final third of the runway in the 2020 construction season. Construction began in June 2019, and in August the project team decided to expedite design and construction of the overlay portion to complete the entire project in 2019. Century West prepared a construction-ready design package for the remaining work within three weeks. This allowed all work to be completed by the end of September 2019 and avoid further impacts to airport operations.
