Portland International Airport Concourse C is a challenging four-phase project that involves extending an existing consource and paving 27 acres of apron and taxiways in the midst of busy operations. A key project feature is a two-level, 120,000-square-foot, steel-framed structure athat adds 10 passenger gates to the airport. Substantial site work, including relocation of aviation fuel lines and utilities, is a critical part of the project. Tight coordination with airport officials is an ongoing challenge to avoid sensitive airport operations, not only for aircraft and ground crews but for the public as well. Concrete and asphalt paving, done in two shifts, required detailed planning to accomodate airplane traffic for takeoffs and landings. An on-site batching plant has been used to facilitate paving and to offset concrete delivery truck traffic at the airport.

Project Cost: $45.8 million
Tonnage: 939 Tons
Sitework Start: March 1997
Completed: May 1998

As part of the Termincal Acces Project, Baugh is adding four stories to the existing three-story parking garage, widening the road in front of the terminal to eight lanes and enlarging the airport's ticket lobby by moving the "window wall" 25 feet. One of the biggest challenges has been to build the improvements with the least posible disruption to airport users.

Project Cost: $105.9 million
Tonnage: 4,257 Tons
Sitework Start: June 1996
Completion Date: March 1999
