end
PURPOSE/ACTION REQUESTED
Authorize execution of an amendment to the contract with Asphalt Surface Technologies Corporation, dba ASTECH Corp, for County Project 98-52 for crack sealing and amend the adopted 2025 Transportation Capital Improvement Program (CIP) budget.
SUMMARY
To provide a safe and efficient transportation system throughout the County, Dakota County undertakes pavement preservation projects on an annual basis to maximize pavement life and minimize pavement life cycle costs. The Transportation Department utilizes a pavement management program to identify pavement segments and the most appropriate pavement preservation treatments on an annual basis.
ASTECH Corp. has contracted to perform the crack sealing in 2025. The number of cracks needing sealing exceeded the County's original quantity, and this has increased the cost of the project.
The original contract amount is $334,392.00. The final cost for actual work is $575,304.00. The difference between the original contract and the final cost is $240,912.00.
To calculate the cost of the project, staff looks at what a representative section of the road and measures those cracks. By extrapolating that section to the entire length of the road, the final quantity is calculated. This process takes place in the fall before the construction year. If the winter is exceptionally cold or if there are several freeze/thaw events, the number and size of cracks can increase which results in extra work and increased costs.
