Kaukauna Dam Tainter Gate Replacement

Kaukauna Dam Tainter Gate Replacement

Scope

Michels repaired and replaced 8 tainter gates and 9 existing concrete piers at the Kaukauna Dam. The dam was last rebuilt almost 90 years ago, and was severely deteriorating. Michels installed a cofferdam around the pier nosings along the upstream portion of the 9 concrete piers, performed select demolition, installed newly fabricated pier nosing, and formed and poured new concrete surface from river bed to the top of the concrete pier.

Crews removed the existing 8 tainter gates and demolished the tailwater portion of the existing piers. Nine new piers, 16 feet and 3-inches long by 5-feet wide by 15 feet tall, were formed and poured. Michels also procured tainter gates that were 20 feet wide by 14 feet tall.
