When the Bosch Corporation of Farmington Hills needed to install an access bridge at the main entrance of their new headquarters building, they turned to The Premarc Corporation. The challenge was turning a fairly nondescript pond, which extends across the front of the building, into a major focal point of the new office complex.

The twin-cell CON/SPAN® structure connected the main road over the pond to the entrance of the Bosch Research and Development Center. A CON/SPAN was chosen because it best combined the aesthetics the architects desired with the economy and flexibility the owner and the contractor were looking for. The MurEbal® retaining wall system was erected along the sides of the pond, 256 feet in either direction from the bridge.

The MurEbal walls were manufactured in 8-foot wide panels and installed on a 1,248-foot radius. Chamfered relief strips were added to the retaining walls and headwalls to match the facing on adjacent buildings. Retaining walls and headwalls project above grade and serve as parapet walls for the entrance and parking lot. The CON/SPAN - MurEbal combination was part of a total design/build package provided by Premarc.
