Substantial work is complete on Daimler Trucks North America‘s new corporate headquarters building on Swan Island in Portland, a $150 million project that has been under construction for nearly two years. The 265,000-square-foot building, designed by Ankrom Moisan Architects, encompasses 9 floors and will house 1,150 employees at full capacity.

Hoffman Construction began work on the site in April 2014 with the demolition of a former shopping mall that was being used as partial office space, and construction of the new building started that July. Approximately 330 steel piles averaging a depth of 120 feet were driven into the dredged site, and stone columns were installed to stop the movement of earth in the event of an earthquake.

A Leadership in Energy & Environmental Design platinum rating will be sought for the building, which includes a green roof, radiant heating and cooling, a living wall, and window placement designed to maximize penetration of natural light, while a separate new four-story parking garage houses solar arrays.

Improvements to the 10-acre site include reconnecting a 1-mile segment of the Greenway Trail along the Willamette River, and extensive outdoor space along the river that includes terraced lawns and space for employees to play lawn games, a bocce ball court, and giant chess set. Mayer/Reed served as the project’s landscape architect.
