Lean, Innovative, and Unique Project Solutions

This project was performed during the winter of 2006 and was scheduled to be completed with frozen ground conditions due to the environmental requirements and restrictions. Due to the mild winter temperatures there was very little frost. Bangor Hydro and Cianbro worked together and successfully completed this project on time while appropriately protecting the environment.
