GHD teams in Guam, Hawaii, Philippines and Australia worked together to deliver the Terminal Aircraft Apron and Taxiway Rehabilitation Project at Guam International Airport for A.B. Won Pat International Airport Authority (GIAA).
The airport plays a key role in connecting Guam to the rest of the world and contributes USD 2.3 billion to the local economy annually. The project covered about 22.5 acres (equivalent to 17 NFL football fields!) of rigid and flexible pavement in the terminal apron area and the adjacent Taxiway Kilo, of which about 12 acres were completely reconstructed from the subgrade level. The project met the aggressive and critical delivery timeframe required by GIAA to secure funding from the US Federal Aviation Administration (FAA).
Initial phases of the design involved geotechnical investigations, non-destructive pavement testing, detailed pavement condition analysis using the Pavement Condition Index rating system, and recommendation of pavement rehabilitation and repair solutions.
The rehabilitation solutions took into account the pavement condition, aircraft traffic loading, acceptable gate closure durations and aircraft taxi routing options.
Upon approval of the recommended rehabilitation and repair solutions by GIAA and the FAA, GHD designed the pavement structures following FAA guidelines and procedures. Our team also developed very useful exhibits such as aircraft tracking scenarios for gate and taxiway closures to inform detailed construction phasing and coordination meetings with GIAA's Operations and Engineering teams, as well as officials from the FAA.
