MBNA America International Headquarters - Wilmington, Delaware As the second largest credit card supplier in the United States, MBNA America undertook an ambitious building expansion program at its International Headquarters in Wilmington, Delaware. This project included the construction of four office buildings totaling over 1,200,000 square feet and four parking garages providing over 2000 structured parking spaces.  The parking garages are located in the lower levels of each office building and are connected by pedestrian bridges. The parking garages use a combination cast-in-place/precast Filigree concrete system. Each structured floor includes a traffic topping membrane for added long-term durability. TimHaahs was retained by Homsey Architects of Wilmington, Delaware to provide functional design, parking control equipment and over-the-shoulder consulting services for each of the parking garages. TimHaahs also provided structural design engineering for the one free standing garage which provides 915 parking spaces.  An interesting aspect of the design was that the owner wanted the column spacing of the building to be dictated by the garages and not the offices above. This resulted in an efficient parking garage layout using a 40'-0" x 40'-0" column grid layout. |
