- Construction Date: November 2019
- Location: Westerly RI
- Category: Cofferdam
In mid-2019 NSI was awarded a contract to construct a cofferdam for an elevator shaft at the Westerly Amtrak station. The high tension overhead catenary wire required work proximate to the lines to be run overnight after the line was de-energized. A passenger conduit -15’ also required special beam anchoring and baffling to shore around the curved bulkhead structure.
