People: architect, Landry + Newman Architecture, Birmingham, Mich.; project manager, Plante Moran CRESA, Southfield, Mich.; civil engineer, NF Engineers, Pontiac, Mich.; structural engineer, Paradis and Associates, Rochester, Mich.; mechanical/plumbing engineer, Sellinger Associates, Livonia, Mich.; electrical engineer, Berbiglia Associates, Farmington Hills, Mich.; general contractor, The Wieland-Davco Corp., Lansing, Mich.; and structural steel fabricator and erector, Builders Iron Inc., Sparta, Mich.
Products: The project utilized 54 pieces of bow string joists, 450 squares of 2-inch-deep composite floor deck and 340 squares of 1.5B roof deck from Nucor Vulcraft Group, St. Joe, Ind.
Fine points: The architects designed a headquarters comprising three sections. Each has curved metal roofs that resemble the curved roofs found in many of Michigan’s farm buildings. The roof has a clear span with no interior columns, giving GreenStone more flexibility with its office space, and a custom-curved roof joist. A series of 54 bowstring trusses cantilever out to form 5-foot overhangs that emphasize the roof and its curve while preventing standing water.
