St. Catherine’s Medical Center, United Hospital System, has selected Riley Construction of Kenosha, Wis., to provide full construction management services on a new $7 million medical office building at its Pleasant Prairie, Wis., campus.

The Pleasant Prairie Plan Commission voted unanimously to approve site and operational plans for the 32,000-sq-ft, two-story building, located just southwest of St. Catherine’s Medical Center.

Construction is expected be completed June 2011. The design is being led by Eppstein Uhen Architects of Milwaukee.

Riley Construction is also currently leading the massive 322,000-sq-ft, three-story addition to St. Catherine’s Medical Center.

The $65 million project adds three new stories on top of the existing hospital, making it one of the largest and most technically challenging health care construction projects in Wisconsin.

Riley Construction is serving as the construction manager on the project, providing preconstruction, construction management and trades performance services.
