At MacDonald-Miller, 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.
"Safe job sites are a critical part of the MacMiller mission. All of us are proud of our 0.5934 Experience Factor - one of the lowest in our industry."
Lee Pyfrom CHST - Safety Director
MacDonald-Miller’s ongoing focus on safety emphasizes training, education, and personal discipline. With more than a hundred OSHA 30 graduates on staff and two OSHA 30 classes taught each year, our team is constantly improving its ability to recognize and avoid hazards on the job.
Our current EMR is 0.5934 – one of the lowest for mechanical contractors in the Washington State Fund. MacMiller is a member of the Approach “Dream Team” and standing members of the safety committees for MCA and SMACNA. We are also a member of WA Group Retro Program, a comprehensive loss prevention program as well as AGC.
Our safety policy matches an enterprise of our size with over 1,000 employees. It is available to all field hands via our computer network, CDs and in printout form.
Each job has a site-specific safety program developed by our Safety Director and implemented by the field foreman and managers. A site safety person is designated at the start of each project from our OSHA 30 graduates. Our Safety Director also regularly performs on-the-spot safety inspections to review site conditions and practices.
We do incident reviews with panel discussions for upper management of selected incidents to emphasize the seriousness of any mishaps.
