RECOMMENDATIONS: That the Board of Public Utilities: 1. Reject the bid of Pacific Industrial Electric as non-responsive; and 2. Approve the award of a contract for the Casa Blanca Substation demolition and site preparation, Bid No. 6956, to the lowest responsive bidder, Genesis Construction of Hemet, California, in the amount of$676,211. BACKGROUND: The Casa Blanca Substation was identified for expansion as part of Riverside Public Utilities' (RPU) Electric System Master Plan (ESMP) in order to keep pace with growth and maintain reliability of the RPU's electric system. Subsequently, the Casa Blanca Power Project (CBPP) was initiated to carry out the ESMP's recommendation for expansion of the Casa Blanca Substation. The CBPP includes the replacement and upgrade of the existing Casa Blanca Substation located at 7615 Evans Street. Furthermore, the CBPP includes the extension of 69 kV sub-transmission lines and the installation of new 12 kV feeders. Ultimately, the CBPP will provide necessary infrastructure for the existing service areas of Casa Blanca, Freeman and Harvey Lynn Substations, as well as outer fringe areas of Orangecrest and Plaza Substations. On February 17, 2011, bids were received for demolition and site preparation work. Out of 30 prospective bidders, only one responsive bid was received. That bid, from International Line Builders, Inc., was $266,000 higher than the Engineer's estimate. Staff was confident that clarifying the bid specification and rebidding the project would improve the number of bids received and would most likely result in pricing more consistent with the Engineer's estimate. On March 18, 2011, the Board of Public Utilities approved the rejection of the bids received on February 17, 2011. The bid specification was clarified, and the project was rebid, On April 14, 2011, four (4) bids were received for the Casa Blanca Substation demolition and site preparation work. The scope of work for demolition includes existing substation structures, buildings, foundations, and overhead and underground utilities. The site preparation scope of work includes the initial grading of the site and construction of a block wall around the perimeter of the substation in addition to the installation of driveways, sidewalk, motorized rolling gates, and some underground utilities.
