WH Canon played an integral role in creating the new world headquarters for General Motor's Powertrain division in Pontiac , Michigan .  We consulted on product and construction feasibility, value engineering and helped establish the construction budget.  WH Canon hand selected the thirty-three specimen Ginkgo trees, shade and numerous flowering trees that were strategically placed throughout the site.  We also constructed 625 lineal feet of free-standing, vertical concrete walls.  To complete the site we installed 10,600 square feet of concrete pavers and site furnishings, including benches and trash receptacles.
