Project Overview

PC’s work for Green Mountain Power includes specialty dam and spillway improvements to address deterioration issues at six distinct sites across Vermont. Work included refacing existing deteriorated concrete dam, replacing concrete crest to enable the installation of an Obermeyer inflatable crest gate system, and refacing existing concrete base slab and walls for the primary spillway.

PC self-performed concrete demolition, dam installation, piping, rigging, equipment start-up, spillway face access construction, and cast-in-place concrete structures.


PC’s four-decade collaboration with Green Mountain Power began with the construction of the Bolton Falls Hydroelectric Plant in 1985. Today, our Special Projects Group continues to provide key construction services on over 200 contracts in Vermont, New Hampshire and New York.
