Completed Under Budget

2021 ACEC Award


Century West performed the design and is currently providing construction observation of the Runway 14L-32R Line-of-Sight (LOS) Rehabilitation Project at the Grant County International Airport (GCIA). Runway 14L-32R is the primary runway at GCIA. The runway is 13,503-feet long, 200-feet wide, and has 50-foot wide paved shoulders. The runway supports operations for ADG VI aircraft, and is routinely used for flight test operations of Boeing 777 aircraft. The current runway profile does not meet FAA LOS criteria as specified in 150/5300-13A, change 1. An existing hump exists in the Runway 14L-32R profile, extending over approximately 4,400-feet of the runway’s north half. The objective of this project is to bring Runway 14L-32R into compliance with FAA LOS standards by reconstructing and lowering a portion of the Runway profile. The project will also include edge lighting replacement, signage updates, shoulder improvements, and replacement of a precision approach path indicator (PAPI). Project efforts have included program definition development, cost estimating, funding acquisition coordination, FAA grant administration, National Environmental Policy Act (NEPA) environmental coordination; topographic survey; geotechnical investigations and analysis; electrical investigations; aircraft fleet mix and Runway Design Code (RDC) determination; facility requirements and alternatives justification study; FAA Flight Procedures and Facilities coordination; runway and taxiway improvements design; project phasing concept development; and identification of permits and other project details necessary for project implementation.
