Body
DEPARTMENT RECOMMENDATION
Community Development Services (CDS), Department of Transportation (Transportation), recommending the Board consider the following:
1) Approve and authorize the Chair to sign the Notice of Acceptance with Trinity River Construction, Inc., for the Starkes Grade Road Slipout Project, CIP 78715/36102014, Contract 2354; and
2) Approve and authorize the Clerk of the Board to release the Payment and Performance Bonds to the Surety upon notification from Transportation, after the one-year guarantee period.
DISCUSSION / BACKGROUND
The contract for the Project was approved by the Board on January 23, 2018, (Item 21). The roadway was opened to motorists on June 5, 2018. Recordation of the NOA will start legal time frames for guarantees, a lien period, and return of retention monies. Recordation of the NOA will also start the one-year time frame for releasing the Payment and Performance Bonds to the Surety.
Direct Construction Cost Summary:
Original Bid Price $ 901,854.45
Contract Item Cost $ 887,286.10
Contract Change Order Cost $ 158,229.49
Total Direct Construction Cost $1,045,515.59
Direct Construction Budget $1,086,000.00
Major Contract Change Orders on the Project dealt with the following:
• Removal of unsuitable material including significant revisions to the drainage system. The site contained a large amount of unsuitable material due to oversaturation and due to the presence of excessive amount of non-earthen materials, such as old timber, root balls, and other organic matter. In addition to unsuitable material, there was far more groundwater present than could have been anticipated prior to excavation. The County issued Contract Change Orders 2 and 2.1 to pay the Contractor to remove the unsuitable material and haul it off site. Contract Change Order 2.1 was approved by the Board on May 22, 2018 (item 47). These change orders also changed the drainage design and added subdrainage to mitigate the excessive amount of groundwater at the site.
The final costs listed are estimates. Transportation will be closing out the Project with the Contractor and finalizing costs over the coming weeks. Any significant deviations from the estimates above that exceed Transportation’s allocated authority will be brought back to the Board for review and approval in a subsequent agenda item.
ALTERNATIVES
The Board could choose not to approve the NOA. Transportation staff would make modifications as directed by the Board and return for Board approval of the NOA. This would delay the release of the Payment and Performance Bonds and extend the Contractor’s warranty period.
