Postma Center, Pine Rest Christian Metal Health Services, Cutlerville, Mich.

The new 15,500-square-foot (1,440-m2) Postma Center is the centerpiece of the 220-acre(88-hectare) campus. The modern and inspirational worship and education center transformed a dilapidated 1960s era gymnasium.

Only a shadow of the former image remains, although a significant portion of the existing structure was re-used. The exterior is highlighted with an undulating wall clad with 5,000 square feet (465 m2) of custom flat lock wall panels using Revere Copper Products Inc.'s EverGreen prepatinated copper supplied by Petersen Aluminum Corp.

Inset in the radius wall at varying heights are vertical colored glass windows. Above and below each window opening are approximately1,800 square feet (167 m2) of PAC Composite Panels finished in Classic Bronze and Platinum fabricated by Petersen Aluminum and installed by Buist Sheet Metal Co.


Buist also fabricated and installed custom copper flat lock panels for the project, in addition to installing standing-seam roof panels fabricated from 0.032-inch (0.8-mm) PAC-CLAD coil finished in Dark Bronze and extensive fascia using Petersen's PAC-3000 CS composite wall panel system.

"Certainly the most complicated part of the job was the custom wall panels," said Don Buist with Buist Sheet Metal. "The architect wanted to maintain a consistent 58-inch (1,473-mm) joint width across the wall including the24 vertical window openings. That meant we had panels ranging from the full 58 inches to as small as 2 or 3 inches (51 to 76 mm) in order to keep the consistent joint locations. The design really required careful layout."

Buist also custom fit 190 feet (58 m) of curved EverGreen coping to cap the radius wall. The top of the coping was hand cut in5-foot (2-m) lengths to fit the curve. Separate face pieces were then soldered to the front and back of the coping while maintaining the curve.
