MBCI IMPs, standing seam roofing complete wastewater treatment facility in eastern Washington

April 28, 2021

When the City of Spokane, Wash., was making plans for a major upgrade of its water treatment facility that would treat an average wastewater flow of 50 million gallons a day, it was important to choose construction materials that would stand the test of time. Insulated metal wall panels and standing seam roofing from MBCI were selected for the new Membrane Filtration Building at the Riverside Park Water Reclamation Facility to help the city with its $126 million project.

“The insulated metal panels were also selected for compatibility with the pre-engineered metal building superstructure,” Kirsten says. “Last, the MBCI insulated metal panels offered the advantage of having the ribbed profile integral with the panel that matches the AMP. This allowed for a cost savings from the approach used on a previous project at the facility, which used a built-up cladding system that was much more labor intensive.”

Two MBCI insulated metal panel profiles were installed as wall panels on the water reclamation facility, 5-inch thick 7.2 Insul-RibTM panels in Medium Bronze (14,250, square feet) and 2-inch thick Striated panels in Slate Gray (9,000 square feet) and Classic Green (9,500 square feet). All have a 22-gauge Galvalume exterior panel. The canopy roofing is MBCI’s BattenLok HS, a 12-inch wide mechanically field-seamed structural standing seam roofing system, also in Classic Green (3,000 square feet).

Halme Builders handled the erection of the metal building framing, assembling framing on the ground outside the building and then craning it into place with a large boom. Halme also installed some IMP roofing, translucent wall panels and skylights, overhead doors and walk-through doors.

Halme Builders recently achieved AC478 accreditation for metal building erectors. The Metal Building Contractors & Erectors Association (MBCEA) introduced the program in 2016 with the goal of recognizing metal building assemblers who are devoted to excellence. Achieving that accreditation provides proof that companies like Halme Builders have the experience and commitment to correctly assemble metal building systems.
