Race Street Pier (Pier 11) Rehabilitation Design & Construction
Penn’s Landing, Philadelphia, Pennsylvania
In 2010, Hydro-Marine Construction Co., Inc. was awarded the contract to perform the structural repairs the Race Street Pier located just south of the Ben Franklin Bridge. The Delaware River Waterfront Corporation planned to transform the 80’ wide by 540’ long abandoned pier into a community park. The pier was originally constructed in the early 1900s and the superstructure later rehabilitated in the 1930s. Extensive repairs and/or modifications were required to ensure the structure was strong enough to support the additional loads.
Areas of heavy section loss in the steel were repaired using new steel channels and/or plates to reinforce the weakened sections. The timber piles were reinforced using shims and clamps. Pre-fabricated steel z-channels were installed along the pier edge as formwork for the proposed deck.
Additional steel reinforcing was required in the large holes cut in the deck for the tree boxes. The original open wharf areas were covered in a steel grid allowing an open view to the water below. Steel plates were anchored in the concrete seawall to prevent further deterioration and to provide formwork for the elevated deck. All work was completed by 2011.
