Barrier System on Award-Winning Education Building in Fairfield, California
by Amanda Storer, director brand marketing, Metl-Span
Because time waits for no one, keeping enclosure time at a minimum was vital in the construction of the Solano County SB 1022 Classroom and Vocational Training Center in Fairfield, California. Building codes require the building be enclosed before much of the inside work begins, so HPCI Barrier Wall Panels from Metl-Span® were prescribed to keep construction moving along.
The classroom is part of the Solano County correctional program that helps inmates rejoin the workforce. That means all exterior and interior details of the building were inspected by the design team to ensure inmates could find nothing to use as a weapon against an officer or another inmate.
“It was a very successful project,” said Kevin Hallock, AIA, NCARB, senior architect at Kitchell CEM of Sacramento, California. “The metal met the owners’ requirements and we were able to do that with a flexible and economical system. It’s an impressive project that ended up achieving LEED® certification.”
Two buildings using the HPCI Barrier System were erected by Quality Erectors and Construction Inc. of Benicia, California. Building A, the classroom and training center, is 11,791 sq.ft., and Building B, the maintenance building, is 32,907 sq.ft. QEC installed HPCI Barrier Wall Panels on steel framing from Garco® Building Systems to provide a finished interior and an exterior backing support for a brick façade along the lower part of the wall and a single skin metal panel from the brick to the soffits. The single skin metal panels were attached to 1-1/2” galvanized hat channels.
“A quick enclosure was essential to getting other trades in the building and working,” said Ethan Law, lead estimator and project manager at QEC. “This system seals up the building. It’s an air, water, thermal, and vapor barrier in a single component, so it’s a quicker install while providing the project’s required R-value.” Hallock expects Building A to achieve LEED Gold status and Building B to receive LEED Silver certification.
The HPCI barrier panels, with a 2” urethane core, allowed for the use of multiple façade options. Exterior and interior panels were 26-gauge Galvalume®, painted igloo white with a light mesa finish. On Building A, the 7,081 sq.ft. of HPCI barrier panels were a backer for a low-rise brick façade and a horizontal single skin metal panel. On Building B, a single skin metal panel was installed vertically on just more than 19,000 sq.ft. of HPCI barrier panels.
“Conventional construction was considered, but in order to meet LEED certification and to do so economically, the metal building and the HPCI panels were the best option,” Hallock said. “The metal wall system allowed us to add batt insulation required to meet the R-value we were hoping to achieve.”
Hallock explains that the color options of the HPCI barrier panels allowed the design team to match colors on nearby buildings that are part of the Solano County campus. The buildings were topped off with a Double-Lok® standing seam roofing system from MBCI®. This unconventional design was thoughtfully executed and the project was voted as 2018’s best by the Metal Building Contractors and Erectors Association in the Educational and Recreational category.
