The Silver Creek Township Board of Supervisors voted unanimously June 26 to approve additional chipseal work, authorizing an Allied contract add-on and a separate intercity add-on despite maintenance staff advising the intercity segment carries the highest risk of cost overrun.
Maintenance staff summarized Allied’s bid for a 4-mile chipseal loop and an option to add 20% to the contract to include additional segments, including 156th Street north of the freeway. Staff said the 20% add-on for 156th Street would be approximately $14,693 and that the township’s total quoted road projects would be about $605,349 if all items proceed.
Staff cautioned that township contracts are priced so the township pays for materials actually used rather than a fixed sum, and that final costs can vary from engineer estimates. Water for the 150th and intercity projects was estimated to add roughly $3,000. Maintenance estimated maximum overages for the two additional projects at about $35,000, or about $40,000 including water. Maintenance recommended not adding the intercity Silver Creek segment because it presented the highest overage risk.
The board moved to approve both additional projects; Vice Chairman Geyen made the motion and Supervisor Nelson seconded. The motion carried 5-0. Minutes record that the township previously decided about four years ago to have maintenance monitor construction rather than hire an external engineer; the minutes note the township can choose to hire an engineer if it prefers.
With the contract add-on, Allied was scheduled to begin work Monday, June 29, per the minutes. The board did not specify additional budget amendments in the minutes; recorded figures are estimates and the minutes state that final costs depend on actual material use.
