Project Highlights

Moxy Hotel

Our full design-build scope of work includes mechanical HVAC sheet metal and piping, Plumbing, and Controls. The hotel floor plumbing fixtures are served by a Sovent combined waste and vent system. Sovent is an engineered, single-stack plumbing waste system that provides increased flows and lower installation costs than traditional waste and vent plumbing systems.

Polyclinic & Swedish Health Services

Full design and installation of a complete HVAC, plumbing, medical gas, and Honeywell Tritium open protocol controls system. Plumbers ran over 6,000 lineal feet of medical gas piping. To accommodate the added medical gas system, a new equipment room was built in the parking garage to house the medical air compressor and vacuum.

Lincoln Square Expansion Phase

The new 1.5 million square feet, mixed-use development in the heart of downtown Bellevue. The MacDonald-Miller team adeptly addressed the unique needs of a mixed-use facility, providing an innovative concept and design, purchasing millions of dollars in equipment, fabricating tons of steel pipe and supports, and engaging thousands of man-hours to install one of the largest commercial central plants in the Pacific Northwest.
