Many of the largest health care providers in the Portland-metro area are contributing to a building boom in the industry, and Legacy Emanuel 鈥� in the city’s Eliot neighborhood 鈥� is no exception.

Andersen Construction in October 2018 began building a new seven-story, 340,000-square-foot expansion of the Legacy Emanuel Medical Center. The firm is serving as construction manager/general contractor for the project, which was designed by Seattle firm NBBJ Architects.

Nearly a year of demolition work took place so the existing structure could blend with the new. Because the building 鈥� dubbed Emanuel West 鈥� is being constructed as a core-and-shell, with tenant improvements to come at a later date, substantial completion is expected by summer 2020.

鈥淲e’re building this structure to tie into medical office building two and the west wing,鈥� said Tony Carson, a senior project manager with Andersen Construction. 鈥淭his building sets off other tenant improvements to improve circulation, and we’re building what we call a bridge even though it’s not really a bridge. There’s a big atrium, and this bridge ties the buildings together and opens up the patient circulation.鈥�

To get to that point, saw crews actually began work almost a year earlier. That allowed for construction of temporary air conditioning and wastewater systems to allow the existing building to continue to operate unimpeded.

鈥淭hey shored the entire structure and saw-cut a six-inch joint between the old structure and where we were going to demo so we weren’t introducing any vibration,鈥� Carlson said. 鈥淭he noise was pretty minimal, but the vibration is the bigger issue.鈥�

Because of this, the structure as a whole consists of a mixture of building types. There are two levels of parking beginning with one at-grade atop a slab-on-grade foundation supported by 211 separate 30-inch-diameter auger cast piles. The second level, a standard post-tensioned concrete deck, is topped by two more post-tensioned decks with cables bonded with grout inside their tubes. The top three levels, including the seventh with mechanical space, are being constructed using a framework of structural steel atop slab-on-deck concrete.

The completed shell space will be able to accommodate 22 operating rooms, seven procedure rooms, up to 40 intensive care rooms, prep-hold-and-recovery rooms, and 34 rooms for the Oregon Burn Center. Legacy Emanuel West will also enhance the health care provider’s treatment capabilities.

A seven-story foyer dominates the entire building at its northwest corner. This features a curtain wall system able to provide large amounts of natural light.

A rooftop amenity space will join a garden to allow patients and guests to enjoy fresh air.
