The Grande Ronde Hospital expansion added a 44,000 SF, 5-story wing to the existing hospital, designed to meet the growing needs of patient care in Eastern Oregon. The second floor serves as a surgery floor with five new Operating Rooms, while the bottom floor is dedicated to mechanical systems, and the first, third, and fourth floors are reserved for future clinical build-outs.

MacDonald-Miller’s scope included HVAC, plumbing, and medical gas piping systems, all of which are critical infrastructure in a hospital environment where reliability, safety, and precision are non-negotiable. The project’s tight ceiling spaces required meticulous detailing and coordination, with medical gas lines, mechanical piping, plumbing, ductwork, and electrical systems often routed within inches of each other. Our detailing team led weekly MEP coordination meetings and supported field crews with on-site BIM data vaults, ensuring real-time accuracy and seamless installation.

Through integrated detailing, prefabrication, and logistical innovation, MacDonald-Miller delivered a high-performing surgical facility that expands Grande Ronde Hospital’s ability to serve the community, while showcasing our commitment to precision and adaptability in complex healthcare projects.
