Past Performance - Building Construction, Renovation, and Repair

Coronado Visitor Center Modifications

Project Description

This project consisted of the modifications to the park’s historic visitor center in preparation for the installation of new interpretive exhibits. The historic building is approximately 1,610 square feet constructed of brick with a clay tile roof. The foundation is slab on grade, housing the visitor center exhibits, bookstore, information desk and administrative offices. The building constructed in 1958 and has had minor alterations since it was originally constructed. The portion of the building that was renovated was approximately 850 square feet. The design efforts required WPC to work with the exhibit subcontractor to ensure that upgrades to the visitor center would meet the electrical and space requirements to the new exhibits.  WPC subcontracted with GLHN Architects & Engineers, Inc. as our subcontracted AE firm to provide the design and engineering for the new space, working closely with the client to ensure that current deficiencies in workspace and design were fixed during the renovations.
