For over 30 years, across many sites, Duffield Associates has maintained a longstanding relationship with Christiana Care Health System (CCHS). Changing demographics necessitated CCHS to expand its main level 1 trauma center hospital campus from 1.4 million-square feet to 2.7 million-square feet to meet the needs of the community. The company naturally trusted Duffield for assistance. Duffield coordinated communications with the public, regulatory officials, and legislators, and provided the requisite engineering services. A major issue for the expansion was traffic congestion so Duffield’s traffic engineers examined 15 intersections in a traffic impact study, while our civil engineers designed and managed the construction of a 700-car surface parking lot to support patients before and during the construction of the expansion. The construction is being completed over many years, on which Duffield continues to serve in multiple capacities. Through this work, Duffield enabled thousands of patients to be served safely and efficiently as they navigate through the main CCHS campus, even as construction and expansion continue.
