The Commonwealth Building in Portland is the perfect setting to site Hermanson’s expansion into the Oregon market.

Built in 1948, the fourteen-story building is listed on the National Register of Historic Places. Recognized by the ASME (The American Society of Mechanical Engineers) as the first large commercial bldg to use geothermal water source heat pumps for heating and cooling, it is an ideal office location for a mechanical contractor.

Hermanson provides unique services not commonly offered in the OR market including sheet metal, plumbing, fitting, engineering, service/maintenance, and precon services.

Additionally, Hermanson has two mini-shops located in Beaverton and Eugene for prefab assembly to reduce trucks on the road, promote on-time delivery, and increase quality control.

With 13 office personnel and upwards of 105 union field workers, Hermanson has been well received by local contractors and continues to seek major projects work in healthcare, K-12 and higher education, hotels, tenant improvements, and residential high rises, direct to owner projects, service, and maintenance.

Hermanson strives to provide inhouse full mechanical services to our clients, hire and retain a quality workforce, and become an integral part of the local community.
