A barrel-vault roof serves as the focal point of the new Western Health Center in Midfield, Alabama.
The two-story, 7246-m2 (78,000-sf) building consolidates three older health clinics into a new facility more centrally located to serve the patient community.
The roof features approximately 929-m2 (10,000 sf) of proprietary mechanically seamed 50-mm (2-in.) red panels installed on a self-adhered underlaying membrane that sits on 150-mm (6-in.) polyisocyanurate (polyiso) insulation. This assembly was installed on an exposed acoustical metal deck on sloped bowstring trusses.
“Being mechanically seamed is important to me in a standing seam roof because of the water resistance and durability,” says Tom Kidwell, senior associate and project architect at Birmingham-based Birchfield Penuel & Associates, which created the design.
The roof features nearly 140 panels, the majority of them being 24 m (80 ft) long, which crews roll-formed and curved onsite. According to CSC Roofing in Birmingham, which installed the roof, the greatest challenge was getting the panels in place, requiring banding them together and building a crate system to lift them to the roof.
The panels are also featured on the canopy at the building’s main entrance, as well as on the roof of a gazebo in a pecan tree grove on the site. Additionally, the design team incorporated standing seam panels and masonry veneer into the interior of the two-story reception area.
The building’s exterior walls also feature 743 m2 (8000 sf) of proprietary panels in tan.
“The materials play together in a fun way to make the project interesting and inviting,” adds Kidwell. “There’s an attractive interaction of the lines on the project. You have the irregularity of the stone veneer interacting with horizontal lines of the metal panels, which are at 90 degrees to the standing seam lines, all of which plays against the precast concrete.”
