Fiscal Impact/Change to Net County Cost:
There is no cost to the County General Fund. The funds from this Amendment I to Contribution Agreement No. 03-0284 will be used to fund Caltrans' share of the construction engineering and construction of the Silvertip Phase 2 Erosion Control Project improvements within Caltrans' right-of-way.
Background:
The Silvertip Phase 2 Erosion Control Project (Project) provides treatment of storm water from both the County's and Caltrans' rights-of-way. The Project includes constructing a larger capacity culvert across State Highway 89, removing the existing culvert crossing, and installing a concrete vault to direct highway runoff into the Silvertip Phase 1 Erosion Control Project treatment basin. Since this Project was of mutual benefit to the State and County, Caltrans agreed to participate financially through the subject Contribution Agreement and originally contributed $75,000.00, which represented the State's estimated share of the construction engineering and construction of the improvements within the State's right-of-way.
Reason for Recommendation:
The purpose of this Amendment I is to increase Caltrans' contribution to the Project by $38,000.00 to reflect the higher than originally estimated construction bid amount for the Project. After reviewing the bid received for the Project from Herback General Engineering, DOT determined that the bid was responsive. There were no irregularities in the bids. The Engineer's construction cost estimate for this Project was $215,366.00. The low bid was $322,056.49, which was higher than the Engineer's estimate. The largest discrepancies between the Engineer's estimate and the low bid were for those bid items related to concrete work and pipe. DOT has seen significant increases in these construction costs this season. Because the bid came in higher than expected, an increase in Caltrans' contribution is necessary.
Action to be taken following Board approval:
1. The Board Chairman will sign the four (4) originals of the subject Amendment I to Agreement 03-0284.
2. The Board Clerk will forward the four (4) originals of the Amendment, along with an original minute order, to DOT for further processing to Caltrans.
3.Upon receipt of the fully-executed original Amendment from Caltrans, DOT will forward it to the Board Clerk's office and retain a copy for DOT's files.
