Renovations for Oregon’s Providence St. Vincent Hospital

Tetra Tech’s High Performance Buildings Group designed renovations to Providence St. Vincent Hospital in Portland, Oregon, resulting in a sustainable and modernized healthcare facility.


  • Size: 296,000 square feet
  • Construction Cost: $19.1 million
  • Client/Owner: Providence Health System
  • Architect: McBride Architects
  • Contractor: Andersen Construction
  • Completion Date: 2013

Needing a renovation that would fully integrate modern, efficient systems without shutting down the hospital, Providence St. Vincent tasked Tetra Tech with performing mechanical, electrical, and plumbing (MEP) renovations. Because there is no downtime in a city hospital, Tetra Tech worked with the hospital to assure the critical needs of patients were taken care of by the medical staff and the facility itself.

Contained entirely within the interstitial areas between floors three and four of a nine-floor patient tower, the hospital’s mechanical systems needed an upgrade. Tetra Tech provided MEP engineering for the project, replacing the existing mechanical air handling, chilled water, domestic water, heating water, steam, medical gas, and electrical infrastructure. Tetra Tech’s decade-long relationship with Providence, along with its collaborative design approach, is what allowed the hospital to remain fully operational during the renovation. A series of controlled shutdowns of existing systems that Tetra Tech previously installed allowed for the successful modernization of the hospital’s MEP systems with no downtime in hospital services. Additionally, more than 27,000 square feet of concrete was removed and replaced with waterproof flooring.

The upgraded, energy-efficient systems resulted in an estimated $500,000 per year in energy-related cost savings. The Oregon Daily Journal of Commerce named the Providence St. Vincent M-Floor Upgrade its project of the year in 2014.
