ELK GROVE VILLAGE, Ill. — Founded in 1952, the original master plan for Indian Springs School in Birmingham, Ala., called for campus development to maintain focus on the lake at the center of the school’s wooded 350-acre property.
During the past 30 years, however, focus was lost at the school that enrolls 280 students in grades 8-12.
As a result, a new plan — complete with a unique metal roof — was made to demolish then construct buildings that re-establish a connection to the lake.
Oversight of design and construction was handled through a partnership of Lake Flato Architects in San Antonio and ArchitectureWorks in Birmingham.
Phase one of a three-phase construction plan consisted of constructing three new cypress-clad, single-story classroom buildings and a new administration building, plus a reroof of an existing library building.
The first phase utilized 45,000 square feet of Petersen Aluminum's 18-inch wide 24-gauge Snap-Clad and Tite-Loc roof panels in Cool Color Zinc. The new buildings, which added 18 classrooms and 18 administrative offices, achieved LEED Silver status.
Installation of the PAC-CLAD roof was completed by Quality Architectural Metal and Roofing in Birmingham. The combination of Snap-Clad and Tite-Loc was explained by Eddie Still, vice president and project manager.
“We used the mechanically seamed Tite-Loc panel on a few areas with pitches that required that profile, which amounted to less than 2,000 square feet.”
Some of the buildings feature monitors, which provide daylighting to each classroom, onto which QAMR installed PAC-CLAD flush panels for both the vertical and horizontal sections.
This was a big job, Still said.
Dealing with Challenges
“Installation went smoothly, but finding manpower to get it done was the problem. The job was big with multiple buildings, and I wasn’t able to stop all of our other projects for this one job,” he said. “So we approached it like four small jobs. This sounded good in theory but there were delays with the work in front of us, which impacted my schedule. This meant I had to put two crews out there to catch up. And then I had to call one of my friendly competitors and put one of his crews out there to help out. I’ve never done that before but it worked out. Plus, these architects were good to work with. We had no issues at all on this project. We worked smoothly together.”
Using the right materials— Petersen’s Snap-Clad panel — helped the project roll along, too, Still said.
“The panel performs well and we’ve never had problems with it. You don’t need to reinvent the wheel, you just need a product you can depend on. We have a 30-plus year relationship with Petersen and they’re great to do business with,” Still said.
The design team sought to respect the school’s original structures’ simple forms and materials while opening the new buildings to nature.
“Our notion was that 21st century schools could actually feel more like 19th century schools,” said Greg Papay, FAIA and partner at Lake Flato, referring to the firm’s back-to-basics approach.
All new buildings feature a roof that extends over covered walkways, Papay explained.
“The roof shape allowed us to create transition spaces around each building that blur the lines between indoor and outdoor areas. We chose a metal roof for longevity, attractiveness and efficiency properties. Plus, Birmingham used to be the steel capital of the south, so to have it on the buildings was a subtle reference to that local history,” he said.
Because of the school’s southern U.S. location, “It was important to find balance between heat gain and glare inside from reflectivity off a neighboring roof, so we had to find the right color that addressed those issues. In the end we chose PAC-CLAD’s Cool Color Zinc.”
Lake Flato’s approach to building materials is to allow each to express its nature, where steel and wood in this application remain light in appearance.
“We want a metal roof to look thin at the edge, so we don’t use heavy fascia. Some people wrap roof edges with fascia and don’t care if its appearance is thick or heavy, but fascia is not part of our approach; we were mindful of the details,” Papay said.
Papay added that these buildings have subtle geometry shifts to accommodate natural rock groupings on the land. Therefore, “there was some roof detailing required where it was not turning at 90 degrees with a simple ridge/valley, so there was some metalworking trickery required at that point. Also we created roof monitors, which are smaller elements that required refined metal work. The roof looks great thanks to a great installation job,” Papay said.
General contractor on the project was BL Harbert International in Birmingham.
