Redstone Dam 2022 Owner Responsible Inspection Program (ORIP)

Project Description

Owners of large dams in Wisconsin are required to have a Registered Professional Engineer, with knowledge of dams, conduct an inspection of their structure. This inspection requires review of existing information, a site visit, completion of an inspection checklist, and submittal of an inspection report to the WDNR.

Ayres Associates has inspected over 150 dams since the inception of the WDNR Owner Responsible Inspection Program (ORIP). All of our inspection have been accepted and approved by the WDNR regional engineers almost exclusively on the first submittal.

Scope of Services

Ayres Associates proposes the following scope of services to complete the County’s required owner inspection to satisfy WDNR inspection requirements.

1. Contact the WDNR to notify the WDNR Water Management Engineer that we will be conducting an inspection at the Redstone dam.
2. Request from the WDNR electronic copies of available information for the dam (last inspection report, photos, database etc).
3. Review the Emergency Action Plan (EAP), Inspection Operation and Maintenance Plan (IOMP) and dam failure analysis for the dam. We will review these reports during the inspection of the dam.
4. Conduct an on‐site dam inspection.
5. Complete the WDNR required checklists, photo documentation, and letter report for each dam and submit to the County for review and approval. Following County’s approval of the reports, forward the final reports to the WDNR Regional Engineer. The letter reports will include a description of any dam deficiencies, any recommended remedial actions and a time line for these remedial actions, as required by the WDNR. Reports will be filed both electronically and in paper copy per the WDNR requirements.

Responsibilities of Owner and Others

The owner will provide access to available documentation about the dam at the time of the inspection. Additional Services

Additional services such as an underwater inspection, setting a benchmark at the dam, and updating reports is not included. If these services are necessary, they would be additional services, and a fee estimate would be prepared.

Time Schedule

We will conduct the inspection in summer/fall of 2022 and submit the report to WDNR within 90 days of inspection.

Fee

We will perform the above services for a lump sum amount of $2,500. Contract Terms and Conditions
