(Grigolla & Sons) for the Total Bid Price of $475,370.00 and authorize the Mayor and the City Clerk to execute the contract. 3.

Construction Company $793,843.00 Note: Total bid amount does not reflect Additive Bid Item No. Al * As -bid amount is $478,435.00 ** As -bid amount is $554,575.00 * ** As -bid amount is $516,910.00 2010 -2011 Sidewalk, Curb & Gutter Reconstruction Project Award of Contract No. 4561 January 11, 2011 Page 2 The low total bid amount was approximately fourteen percent (14 %) below the engineer's estimate of $540,500.00. The current competitive construction market most likely contributed to the disparity between the received low bid and staff's cost estimate. The engineers estimate was developed based on the unit prices received from last year's concrete reconstruction project. An additive bid item to replace existing handrails at San Miguel Park was included in the bid package. After review with General Services Department staff and evaluation of the bid pricing, Staff recommends including the Additive Bid Item, Al, to the contract at a cost of $13,000.00, resulting in a total contract of $475,370.00. The low bidder, Grigolla & Sons, possesses a California State Contractor's License Classification "A" as required by the project specifications. A check of their references indicates they have satisfactorily completed similar concrete projects in past few years. Public Works' staff believes Grigolla & Sons can successfully complete this year's concrete reconstruction project. Given the favorable project unit prices by Grigolla & Sons, staff recommends Council to establish a twenty percent (20 %) contract contingency to be included in the contract award, totaling $95,000.00. Those added funds will provide an opportunity for the City to take advantage of the low unit prices to perform additional concrete repairs at other locations. This project consists of existing sidewalk, medians, driveways, curb and gutter, alley approaches, curb access ramps; replacing concrete stair cases; pruning tree roots; and installing new tree root barriers per City standards primarily within the Eastbluff Community and Balboa Island. Pursuant to the Contract Specifications, Grigolla & Sons will have 85 consecutive working days to complete the construction. ENVIRONMENTAL REVIEW Staff recommends the City Council find this project exempt from the California Environmental Quality Act ( "CEQA ") pursuant to Section 15302 (Replacement or Reconstruction) of the CEQA of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential to have a significant effect on the environment. PUBLIC NOTICE The Notice Inviting Bids was advertised in the City's official publication and in construction industry publications. Prior to starting work, two City prepared notices will be distributed by the contractor to the nearby residents. The first notice will be distributed ten days before starting work and the second notice 48 hours prior to starting work. 2010 -2011 Sidewalk, Curb & Gutter Reconstruction Project Award of Contract No. 4561 January 11, 2011 Page 3 Geotechnical, Materials.
