Duffield Associates’ Projects Win Awards

The second project “Lumberyard No Longer Hammered by Flooding” won the Outstanding Civil Engineering Small Project Award from the American Society of Civil Engineers, Delaware Section.  On this project Duffield Associates conceived and designed a flood proofing project for the Shone Lumber Company’s sprawling, flood-prone showroom/warehouse facility in Stanton, Delaware.  Additionally, Duffield Associates: assisted in preparing and applying for a FEMA flood-proofing grant; conceived specially designed flood “gates” to protect 11 overhead and personnel doors; provided engineering/permitting and preparation of construction drawings and specifications; and, provided construction management services.  Using a number of innovative approaches to integrate flood wall construction with building elements, Duffield Associates achieved a cost-effective solution which was implemented while not disrupting Shone’s ongoing retail and shipping operations.

These awards continue Duffield Associates’ 35 year legacy of receiving recognition for excellence in engineering.
