McKenzie-Willamette Medical Center


To better meet its goal of giving the community great healthcare, the McKenzie-Willamette Medical Center was renovated and expanded — nearly doubling the size of the facility and renovating about 25 percent of the existing building.


Through BIM and innovative processes, Southland performed mechanical, plumbing, and piping services for the construction of a new four-story patient tower and powerhouse replacement along with 40,000 square feet of major interior renovation and 26,000 square feet of minor interior renovation. Utilizing careful collaboration, the facility remained open during the entire construction period.

Additionally, innovation and extensive planning was used to build a new central energy plant around the existing plant. One of the greatest challenges of the project was to keep the hospital operable during construction, requiring acute efforts to sequentially demo, install, and commission new boilers, chillers, and pumps without causing lag in facility operations were required.


Southland successfully provided full mechanical, plumbing, and medical gas on the 153,000 square foot addition to the hospital which added patient beds, additional operating rooms, and doubled the size of the emergency department.

The 56,000 square foot renovation to the existing hospital included work performed on the hospital’s existing central sterile, emergency department, Post-Anesthesia Care Unit (PACU), and operating rooms. This included 9 air handling units, 3 boilers, 2 chillers, 3 cooling towers, 37 exhaust fans, and a medical air compressor and vacuum system.

Overall, approximately 16 miles of plumbing and medical gas piping was installed in addition to 130 tons of HVAC sheet metal to renovate and expand the McKenzie-Willamette acute care hospital.
