We make buildings work better.

MacDonald-Miller Facility Solutions is the top choice, full-service, design-build, mechanical contractor in the Pacific Northwest.

We want to make your facility run the best it can.

With over 1,000 talented professionals, 10 locations and our own fabrication shop, no project is too small or too big. Whether you simply have a service call, or are planning a 40-story office building, we have the right team of system experts – for you and your buildings’ needs.

Experience your project before it's built.

This 750 sq. foot space provides our customers with the ability to explore a project in Virtual Reality, make real-time adjustments to a building model and immediately see the results in VR. Connecting capabilities to access design files, make live adjustments, and get team involvement instantaneously, we are fast-tracking the way projects are built. Go beyond drawings and shared files. Now you can walk through your building and interact with the systems before it’s built.
