Approve Change Order #1 to the 2021 Sanitary Sewer Lining Program
COUNCIL ACTION REQUESTED
Council is requested to approve Change Order #1 to the 2021 Sanitary Sewer Lining Program which modifies the
scope of areas planned for improvement.
BACKGROUND INFORMATION
Following the original scoping and bidding of the 2021 Sanitary Sewer Lining Program two key factors
influencing the proposed improvement areas changed:
1.The originally planned lining areas along portions of Highland Drive, Brittany Road, and 17th Street West
were identified as needing street reconstruction within our 5-Year Capital Improvement Plan. As to avoid
disturbing these areas twice in a short window of time, staff concluded that the sanitary sewer in these
areas can be delayed for improvement until the CIP program reaches these streets in the near future.
2.To take advantage of good bid pricing and maximize the available budget for 2021 sanitary sewer lining,
staff identified the trunk sewer line that loops from 15th Street West through the Hastings Golf Club as
the the preferred alternative. This loop has historically been difficult to maintain as any cleaning or
maintenance must be closely coordinated with golf course operations. Also, this loop is in close
proximity to the sewer lining already planned for in the golf course between Hilltop Lane and Valley Lane
making this a cost-effective time to complete lining operations in this area.
FINANCIAL IMPACT
If approved by Council, the net cost to the City to modify the improvement areas as described is $19,735.22.
This additional cost is well within our project budget and still leaves sufficient contingency for other unforeseen
costs if they occur during construction. A summary of the 2021 Lining Program’s current budget outlook:
• Total Project Budget: $332,000
• Original Bid Amount: $272,855.90
• Net Increase Change Order #1: $19,735.22
• Revised Bid Amount: $292,591.12
• Remaining Project Contingency: $39,408.88 (13.4%)
