Vorelco -------------------------------------------------------------------------------- Duffield Associates was retained by Vorelco to provide value engineering for a proposed 42,000 square foot post-production automobile preparation facility at the Port of Wilmington in Delaware. This facility, which prepares and modifies imported automobiles for dealers in the United States, had to be constructed on a fast track design and construction schedule within tight budgetary constraints. Due to the presence of approximately 100 feet of soft compressible soils beneath the proposed site, a previous design of the facility prepared by another engineer had recommended construction of a pile-supported foundation system. After reviewing available information and performing supplemental investigations, Duffield's team of geotechnical and structural engineers designed a method of stabilizing the subgrade to allow this almost one acre structure to "float" over the underlying soft soils. This innovative design, utilizing cement stabilized fly ash and crushed stone, eliminated the need to constructed five hundred, 100-foot long piles and associated pile caps. Because of the cost and time savings realized, the Vorelco project was successfully constructed well within budgetary and scheduling constraints. The Duffield design team's recommendations resulted in a cost saving to the owner of over $1 million and allowed acceleration of the project's construction schedule by over two months. This design received the Grand Conceptor Award at the Consulting Engineers Council of Delaware's Engineering Excellence Design Competition. |
