RECOMMENDATIONS: That the Board of Public Utilities. 1. Reject the bid submitted by Emad Nabih in the amount of$140,891.29 as non-responsive; 2. Award a contract for the Permanent Trench Resurfacing for California T- Bel Air 8-inch Water Distribution Main Replacement Project, Bid No. 6862, to the lowest responsive bidder, Laird Construction Co., Inc., of Rancho Cucamonga, California, in the amount of$141,525.93; and 3. Authorize the issuance of change orders to the purchase order of up to twenty-percent of the original amount for Bid No. 6862. Such changes will be reported to the Board of Public Utilities at the conclusion of the project. BACKGROUND: The construction of the California—Bel Air 8-inch Water Distribution Main Replacement Project as part of the on-going water main replacement program was approved by the Board on March 5,2010, including all costs for engineering,construction,and paving. The construction of the water pipeline is currently underway by the City's field forces, and the anticipated completion date for the pipeline work is mid-September 2010. The Work Order that was previously approved by the Board includes$300,000 for pipeline trench resurfacing. The bid documents for the paving work entailed trench resurfacing, including grinding each side of the trench areas and applying new asphalt concrete flush with the existing asphalt per Public Works standards within the affected streets as shown on the attached project site map. The work would also include the application of new traffic striping and pavement delineation as needed. In an effort to fully restore the roadway surface and avoid large overlays of the lateral trench crossings, as required by the Public Works Department trench resurfacing standards, staff is proposing to flush pave the trenches and slurry overlay of the full street. Although slurry seal was not a part of the original bid,the Public Works Department has agreed to this approach. Staff recommends augmenting the customary ten-percent change order amount by increasing it to twenty-percent. This will ensure that the project will continue on schedule and will avoid unnecessarily inconveniencing the residentswithin the project vicinityfor an extended period.
