Project Details
The Mt Tom Power Site was the location of an obsolete coal power plant on the CT River dismantled in 2016. NSI was contracted to build two coffer dams (125’x60’x125 and 50’x25’x50) to allow the excavation and removal of the facility’s water intake and discharge piping in the river. This effort required extensive obstruction removal during sheet installation. Fifty foot sheets and two sets of steel bracing were installed to permit the dewatering and structure removal. A 250ton crawler crane was required to provide the 170’ reach for the sheet pile installation.
