Precision and persistence proved essential in the construction of the new air traffic control tower at Portland International Airport. An early completion goal needed to be met, all while the highest level of technical and architectural detail was maintained.
The upgrade of a 165-foot tower to one that exceeded 265 feet, and the resulting new viewpoint from a cab 100 feet higher, was part of the story. The tower also had to comply with standards that met all eventualities in a Seismic Zone 3 condition.
The foundation required four seven-foot caissons embedded 130 feet deep, as well as a structure in precast with stitch wall applications. A structural steel top cab was placed to provide a territorial view of all airplane operations. An 11,000-square-foot Support and Administration Building was constructed to integrate all functions related to air traffic control missions.
The end result was spectacular. The PCL team’s focus led to completion six weeks ahead of schedule, and the facility was awarded the Federal Aviation Administration’s Facility of the Year Award. Teamwork and tenacity were the keys to a great result.
