The Castle Group

In 2015, Castle completed work as a sub-consultant of G.W. Management on a design/build job at the Nimitz Library on the US Naval Academy. The work consisted primarily of the assessment, repair development, and rehabilitation of 27 concrete pile caps that support the library, which exhibited signification deterioration due to exposure to the brackish tidal waters of College Creek and the Severn River. Castle completed the design of the repairs and Hydro-Marine completed the construction.

Atlantic City Electric Project

On March 16, 2006, the Quay Pier along the Delaware River located in Penn’s Landing was struck by a tanker causing extensive damage to the pier. Since Castle had previously performed the inspection and repair of several piers for DRWC, Castle was requested to perform an emergency underwater inspection of the pier to determine the extent of the damage. Hydro-Marine performed the emergency underwater repairs required to stabilize the pier. These repairs were completed by July 2006.[3][4][5]

Roebling Bridge

In January 2010, Hydro-Marine divers assisted Atlantic City Electric in locating and repairing a damaged submarine power cable. There were approximately 500 to 600 feet of damaged 25K submarine cable lying under the ground. To locate the break in the cable, Atlantic City Electric had to send a high-frequency sound through the cable, while Hydro Marine divers used a Cable Finder to locate the exact point of the break. For each break that was found, workers repaired it by cutting out the faulty section and then splicing in a new section of cable.

Once the cable was fully repaired, it was then placed back on the channel bottom and reburied by jetting. The entire project was completed by late February 2010.[6][7]

Castlewas retained by WRS Infrastructure & Environment, Inc. in October 2008 to perform an in-depth inspection of the Roebling Bridge, in Roebling, New Jersey. Once the analysis was complete, Castle designed a new bridge utilizing the existing main steel beams and the concrete substructure with modifications and repairs. Hydro-Marine performed the actual construction of the bridge. Removal of the existing structure began in November 2008, the deck was poured the first week in January 2009, and the bridge was open to traffic by January 23, 2009.[8]
