The project also included crack filling and slurry seal work but these items were deleted from this contract and added to the American Asphalt South, Inc. contract (2011 -2012 Citywide Slurry Seal Project, C- 5087). The contract has now been completed to the satisfaction of the Public Works Department. A summary of the contract cost is as follows: Original bid amount: Actual cost of bid items constructed: Contract change orders: Final contract cost: $ 1,886,120.00 $1,441,386.99 $ 84,354.25 $ 1,525,741.24 The disparity between the contract award amount and the final construction cost was the result of deleted bid items noted above and alternative measures to reconstruct deteriorated pavement sections. After a field meeting with the contractor to review these areas, it was determined that there was no apparent failure with the base material and that a deep grind and thicker asphalt overlay would suffice. The final contract cost was 19.1 % below the original contract amount. There were two change orders totaling $84,354.25. The change orders were for the deletion of the slurry seal bid items (bid item no. 8 & 9) and additional street repair work for Dorchester Drive in the Cameo Highlands community. In an effort to coordinate with the Irvine Company's construction of a new intersection at Newport Center and Center Drive and the new Pimco 22 -story high -rise building, the City delayed the start of our paving operations until after Memorial Day. City staff also requested that EBS bring in extra equipment and additional workers to complete the work in a more expedited manner. The schedule for all the paving and slurry work around Newport Center allowed 50 working days based on past paving and slurry projects. The project was substantially completed July 13, 2012, but the Dorchester Drive work required additional time extending the completion date to July 31, 2012. 2 of Fashion Island Area Streets Overlay and Slurry — Notice of Completion and Acceptance of Contract No.4813 August 28, 2012 Page 3 A summary of the project schedule is as follows: Estimated Completion Date per July 2011 Baseline Schedule: June 29, 2012 Project Awarded for Construction: April 10, 2012 Completion Date from Award with Approved Extensions: July 31, 2012 Actual Substantial Construction Completion Date: July 13, 2012 ENVIRONMENTAL REVIEW: City Council found this project exempt from the California Environmental Quality Act ( "CEQA ") pursuant to Section 15301(c).
