Multiple Recommendations

Possible action:
a. Approve Contract Change Order No. 1-Final - Capitol Expressway ITS Infrastructure and Sidewalks Project, Contract No. 18-06. Contractor - Granite Rock Company. Net decrease of $145,698 and a decrease of 23 working days.
b. Accept Project as complete and authorize the Clerk of the Board to execute Notice of Completion of Contract and Acceptance of Work on the above.



There is no fiscal impact to the General Fund. The unused supplemental work allowance previously encumbered by Board action when Contract No. 18-06 was awarded will be redistributed to the appropriate Road Fund account.


Contract No. 18-06 was awarded to Granite Rock Company on April 17, 2018. The Notice to Proceed was issued on May 14, 2018. The contract compensation amount was $6,105,336 which included a supplemental work allowance in accordance with the Contract Documents; 200 working days were approved for project completion.


The project Base Bid provided for the installation of Intelligent Transportation System (ITS) infrastructure to support implementation of a state-of-the art traffic operations and management system on Capitol Expressway between Narvaez Avenue and Highway 101. New traffic signals, curb ramp improvements and additional left turn lanes at McLaughlin Avenue were also part of this work. Alternate Bid Item 1 provided for pedestrian improvements on westbound Capitol Expressway providing installation of new sidewalk between Senter Road and Tuers Road, thereby eliminating an existing sidewalk gap. All work authorized by Contract No. 18-06 has been completed in the field and the final inspections have been held. The increases and decreases in the contract items of work represent adjustments from the previously approved estimated quantities to those expended to complete the project. A final balancing change order resulting from monetary adjustments in bid items requires a simple majority vote by the Board as the contract compensation ceiling was not exceeded.


The recommended action will improve expressway operations and safety, positively impacting all roadway users, including children and youth throughout “Every Child Safe” indicator.


The recommended action will improve expressway operations and safety, positively impacting all roadway users, including seniors.


The recommended action will have no/neutral sustainability implications.


The County would be unable to execute the Notice of Completion for Contract No. 18-06 and would not be able to release retention in accordance with the Standard Specifications, 7.43 – “Acceptance of Work” despite project completions. The subject contract would not be closed, and the County would be precluded from making the final payment to the Contractor in accordance with the Contract Documents.


The Clerk of the Board Shall:

1.     Forward the Notice of Completion and Acceptance of Work to the County Recorder for filing.

2.     Send notifications of Minute Traq to: Jamil Salas, Rowdy Pipkin, Albert Eydam, Debra Floresca-Roads & Airports Department – Infrastructure Development Division

Tony Arata, Pam Rebillot, Kelly Roberts – Roads & Airports Department – Administration
