The firm’s transportation division led high-impact projects in 2025, including the I-5 over SW 26th Avenue Bridge Replacement, which featured a meticulously planned 56-hour roadway closure that minimized traffic disruption while reducing construction costs. The project earned six honors, including the 2025 ACEC Oregon Project of the Year Award and ACEC National Recognition Award.

Additional recognition came for the Stark Street Bridge Emergency Wall Repair Project, which was named the 2025 APWA Oregon Historical Restoration/Preservation Project of the Year. The SW Walker Road Improvements Phase 2 Project was named the 2025 APWA Oregon Transportation Project of the Year.

The company’s water and environment, energy, and land development business units also have been recognized with industry awards for the Fanno Creek Trail Improvements Project, the Mirror Lake Trailhead at Government Camp and Mountain View Champions Park projects, and a solar interconnect design supporting regional grid integration.
