Construction began in May and is essentially complete, with only minor remaining work to be completed in the Spring of 2022.
The County Board delegated the authority to award CP 91-25 by Resolution No. 21-044 on January 19, 2021. The contract was awarded administratively by the County Manager to Mathiowetz Construction Company on March 24, 2021, in the amount of $5,780,346.04. Note that the Engineer's estimate for the reconstruction was $7,548,000, nearly $1.8 million over the low bid.
Construction costs have increased by $382,392 or 6.6 percent due to additional excavation, aggregate surfacing, bituminous, box culverts, drainage, fencing, erosion control, pavement joint adhesive, and incentives. A list of item overruns and contract changes is summarized in Attachment: Cost Increase Summary.
