FROM: Tim Weidner, P.E., Engineering Coordinator
DATE: August 24, 2023
SUBJECT:
A Resolution to approve Change Order #1 with Geneva Construction Co. in the amount of $160,000.00 for the Spruce Street Watermain Repair and additional City-Wide Resurfacing Project costs.
PURPOSE:
To approve Change Order #1 to the 2023 City Wide Resurfacing Project.
BACKGROUND:
Due to a large watermain break, the pavement along Spruce St between Lake St and River St has heaved and been significantly damaged. Additionally, as the City-Wide Resurfacing Project has worked through several wards, it has been determined that more concrete deterioration has occurred over the previous winter than initially anticipated.
DISCUSSION:
Geneva Construction Co. is currently under contract for the 2023 City Wide Resurfacing Project. Bids for this project were opened and publicly read on April 5, 2023, and Geneva Construction Co. was determined to be the lowest responsible bidder. Construction on the project has been ongoing throughout the summer. The current contract value of the project is $9,471,220.17.
A large watermain break occurred along Spruce St earlier this year. The resulting water release caused significant structural damage to a section of Spruce St as evidenced by pavement heaving. See the pictures in Exhibit 'A'. The area was temporarily patched, but a more significant long-term repair is needed for the middle of the block which is still damaged.
City staff recommends completing this repair work under the 2023 City Wide Resurfacing which would allow for less expensive repair compared to bidding as a separate project due to benefitting from economies of scale and already mobilized work forces. A number of the pay items required are pay items in the 2023 resurfacing project, and Geneva Construction has provided reasonable agreed unit prices (AUPs) for the work not in the contract. This work is estimated to cost $60,000.00 which was under the value we estimated. The attached Exhibit 'B' is an estimate of cost and Exhibit 'C' is the proposed scope of work and limits.
As a separate issue, as work has been completed throughout the first several wards, construction efforts to fully repair deteriorated streets has proved more excessive than anticipated at the time of bidding. In particular, concrete curb and sidewalk replacement quantities have been trending higher than expected. Some additional cost may be required to finish repairing the deteriorated streets in the program to City standards throughout the remaining wards. Staff is asking for additional moneys to complete the project in case they are required. This work is estimated to cost $100,000.00, see Exhibit 'D'. The items in Exhibit 'C' represent a 1.06% increase in contract value.
The 2023 City Budget provides funds for this project in the following accounts with money to be transferred and/or unencumbered as necessary:
|
Repairs and Maintenance |

510-4063-511.38-38 |

|
Capital - Neighborhood Imp |
GB097 |
340-4060-431.73-91 |
$100,000.00 |
IMPACT STATEMENT:
Spruce Street will be temporarily closed to complete the pavement repairs. Remaining City Wide Resurfacing streets will be constructed in accordance with City standards requiring occasional lane closures.
RECOMMENDATIONS:
Please forward this resolution to the Finance Committee for their review and recommendation for approval.
