MacDonald-Miller Facility Solutions

At MacDonald-Miller Facility Solutions, we make buildings work better. Period.

We are a full-service, design-build mechanical contractor in the Pacific Northwest. With over 1,000 talented professionals, 10 locations, and our own prefabrication shop, no project is too big or too small. We’ve helped shape the local landscape for over half a century with buildings that operate in the most efficient manner possible. We like to think we’re saving the planet one building at a time.

Facility managers, owners, and tenants can all rest assured that our experience as industry leaders lends itself well to tackling the complexities of their industries–healthcare, biotech/labs, industrial, marine construction, commercial office buildings, and residential projects. We’ve done it all. And if we have our way, we’ll keep doing it for the next 50 years.
