Amended Agreement for Professional Services between Sauk County Land Resources and Environment Department and Ayres Associates Inc.

In January 2020, the Owner retained the Consultant under the original agreement for design, bidding, and construction engineering services for repairs to Hemlock Dam.  Per the agreement, the Consultant completed the design of those repairs and submitted plans and specifications to the WDNR for permit approval.  The Consultant coordinated with the WDNR to respond to their review comments and prepare a final, approvable set of plans and specifications in June 2020.  Later that month, the Owner received a commitment from the WDNR to fund a Municipal Dam Grant for the proposed repairs to Hemlock Dam.

After receiving a commitment from WDNR to fund the Municipal Dam Grant, the Owner learned of several issues which significantly increased the estimated costs of the repairs to Hemlock Dam and for future ongoing maintenance.  As a result, the Owner is now pursuing reconstructing Hemlock Dam to be a smaller structure so that it not longer is required to meet the WDNR's jurisdictional requirements for large dams.  This amendment to the original agreement is for the Consultant to provide engineering services for the design, bidding and construction of a small dam to replace the existing large dam at the site.

Attachment A - Scope of Services

Repeat the Scope of Services included in the original agreement for a proposed replacement water control structure meeting the requirements of a small dam by the WDNR.  Work products resulting from the original agreement will be used to complete the Scope of Services for the amended agreement, as appropriate. 

In addition, amend the original agreement as follows:

• Remove Task 1.4.5 Prepare and submit the WDNR Municipal Dam Grant Application on behalf of Owner.
• Add Task 1.5.8 attend an at-site pre-bid meeting to meet with prospective Contractors and answer questions.

Attachment B - Period of Services

Amend the Period of Services so that Preliminary Design Phase documents are due to the Owner within 120 days of receiving authorization to proceed and Final Design Documents must be submitted to the WDNR with 30 days of the Owner's acceptance of the Preliminary Design Phase documents.

Attachment C - Compensation and Payments

In 5.1.1.1, increase the total Lump Sum compensation by $38,150 from $38,041 to $76,191.

Of the $38,150 increase, the assumed distribution of additional compensation by task is as follows:
