In response to an increasing parking demand on the Concord Hospital Campus and in anticipation of proposed expansion to the ER and OR departments, Waterfield Design Group was selected to provide design and construction management services for a new 450 space parking structure. For this design-build project, our work included conceptual sizing and layout, surface parking and circulation design, grading and drainage, and landscape and foundation design. An underground detention basin was used to maximize parking capacity and prevent increased runoff. Our innovative approach saved the owner nearly $2.2 million in construction costs.
