This 126-acre site was the largest brownfield in the United States with an industrial history dating back to 1861. It was a mix of mill buildings, blast furnaces, offices, cranes, trestles and historic structures. Scope of work included preservation of some of the most significant Bethlehem Steel buildings and construction of a casino, 3,231 space parking, and retail mall. New construction reflects the architecture and industrial heritage of the former Bethlehem Steel. Structures are composed of steel trusses, steel frames with brick infill, concrete, corrugated metal sheathing and gabled roofs with clerestories and light monitors. Interior spaces employ wood block floors, exposed skeletal steel, backlit perforated metal screens and soaring transparent glass monitors. Sitework involved demolition of unused structures, removal of existing concrete foundations, building site preparation, erosion control and landscaping. Development required new roadways, on-site paving, pedestrian sidewalks and site lighting. Highway improvements included the addition of a new turning lane to a PennDOT bridge traversing the site. Site utilities included sanitary and domestic water service tied into local utilities. Stormwater control measures used during construction included a large retention pond at the northeast corner of the site.
