RT Group, Inc. (RTG) was retained by Modern Continental Construction Company (MCC) to prepare select engineering submittals associated with the construction of the Narragansett Bay Commission (NBC) 032 Facilities Project (NBC Contract No. 01:302.10-C). This project included excavation support design for several below grade structures ranging from about 30 to 40 feet deep, the design of a 220- foot-deep drop and vent shaft, dewatering design, support of excavation design, and construction claims support.
There were two (2) below grade structures that RTG was responsible for. Each excavation support system consisted of an internally braced steel sheet pile wall.
Dewatering was accomplished using internal sumps and pumps and collected water was discharged through a sedimentation basin designed by RTG.
RTG utilized Embedded and Lined Cylinder Pipe (ECP and LCP) for the 220-foot-deep drop and vent shafts. This innovative design was developed by RTG on NBC Contract No. 01:302.08-C, and required special connection and lifting details to allow the pipe to be installed in the “wet” and in a vertical position. This was the first time this technique had been utilized in the United States, and RTG’s design was selected by MCC after observing its success on the other NBC Contract. RTG’s design not only saved MCC time and money, it resulted in a product that is superior in the opinion of the NBC (the Owner).
