The project scope included the demolition and replacement of the walk bridges and support piers that provide access over the dam spillways.  Local cofferdams were built to facilitate the phased removal of the walkways and piers.  23 new concrete piers were installed.  31 existing walkways were removed and replaced with new.  This work covered a total of four sites along the lower Fox River in Northeast Wisconsin.  We were able to deliver this project one year ahead of schedule by leveraging Lunda’s marine construction resources to work on as many as three sites at the same time.  Lunda partnered with USACE on this project and used the USACE RMS/QCS software to implement and control the Contractor Quality Control program that this project required.
