Resolution to Authorize an Amendment to a Contract with Ayres Associates for Engineering Services for the Delton Dam

BACKGROUND: During the 2019 inspection of the Delton Dam, it was noticed that there was a concrete spalling and repairs were necessary.  In June 2022, the County entered a contract with Ayres Associates to engineer the project.  A second inspection in December 2021, noted that a concrete training wall near the edge of the dam shifted.  In discussion with representatives of JF Brennan on-site as well as phone conversations with Ayres Associates, this was not an imminent issue, but did need to be addressed.  The LRE Department amended its contract with Ayres Associates to include this scope of work, which was approved by the County Board by Resolution No. 5-2022 on January 18, 2022. 

Upon submittal of plans to the Department of Natural Resources; and further engineering investigation of the issues at the dam, it was found that the plans need to be amended to address other items that have been identified.  The LRE Department would like to amend the engineering contract to refine the plans to address all issues at the dam.
