Diamond Materials is undertaking the 366 Shell Road project in Carneys Point, New Jersey, on a time-and-materials basis for Pierson Materials. The purpose of this project is to perform all necessary site work for the construction of a new concrete plant. Originally anticipated as a six-to-eight-week project, the schedule has been extended due to unforeseen subsurface conditions and utility conflicts encountered during construction. Diamond Materials is currently targeting completion by the end of the summer while continuing to address these site challenges and maintain progress.
The scope includes development of a 6.35-acre site, including approximately one acre of clearing, 3,861 cubic yards of cut-to-fill earthwork, and 11,207 cubic yards of imported fill material. Utility installation consists of approximately 1,200 linear feet of storm drainage and 100 linear feet of sanitary sewer. Paving and concrete operations include placement of 3,850 tons of asphalt, 1,150 cubic yards of concrete, 1,789 square feet of sidewalk, and 1,138 linear feet of curb. The project also incorporates three stormwater management facilities, including two infiltration basins and one bioretention basin designed to support site drainage and regulatory compliance.
A number of unforeseen challenges have significantly impacted the project. During excavation, crews encountered extensive concrete deposits extending to the water table that required removal to facilitate construction of the infiltration basins. In addition, an aging storm pipe system serving a neighboring golf course was discovered beneath the site, with multiple collapsed sections requiring repair at the direction of Carneys Point Township. The pipe alignment also conflicts with the site's septic field zone of influence, necessitating design modifications and coordination among project stakeholders. Further complicating operations, an existing utility installation crosses directly through the pipe corridor, creating additional constraints on repair efforts. Through ongoing coordination, adaptive planning, and field problem-solving, Diamond Materials continues to overcome these unforeseen conditions while advancing construction toward project completion.
