DISCUSSION: At 2:00 p.m. on October. 12, 2006 the City Clerk opened and read the following bids for this project: BIDDER Low G.C.I. Construction, Inc. BIDDER Low G.C.I. Construction, Inc. BIDDER Low G.C.I. Construction, Inc. BASE BID AMOUNT '$359,350.59 Corrected Bid Amount is $359,305.50 ADDITIVE BID AMOUNT $ 20,000.00 TOTAL BID AMOUNT $379,305.50 The corrected low total bid amount is 287% above the Engineer's Estimate of $122,000. The disparity between the estimate and the actual bid price reflects the specialized work involved, limited number of contractors able to bid, and concerns about how construction might be impacted by the rainy season. The low bidder, G.C.I Construction, Inc., possesses a California State Contractors License Classification "A° as required by the project specifications. The Contractor has satisfactorily completed similar projects for the City of Newport Beach. Project Description: A maintenance access road leads into Buck Gully near the intersection of 5t' Avenue and Poppy Avenue. At the canyon bottom, there is a roadway crossing a creek that is severely degraded and the crossing must be used cautiously. Immediately upstream and downstream of the roadway crossing, the streambed has experienced significant Buck Gully Wetlands and Maintenance Road Repairs ale Street— Reject Bids for Contract No. 3778 October 24, 2006 Page: 2 erosion due to the overall erosion of Buck Gully that has occurred over the past 15 years. The proposed design includes installation of gabion drop structures to stabilize the creek bed and to create wetland areas. The design calls out for roadway headwalls, roadway cap and storm drain culverts to be replaced or refurbished. The project requires permits from the Army Corps of Engineers, Regional Water Quality Control Board and California Department of Fish and Game. These permit applications have been submitted, however, agency permits and approvals have not yet been received. The' project falls outside the jurisdiction of the California Coastal Commission. The area does fall within the Natural Communities Conservation Planning (NCCP). area and the NCCP administrator, the Nature Reserve of Orange County, has been notified about this proposed project. The project is broken down into two phases as described below: • Phase 1 includes repair of the existing concrete "Arizona" roadway creek crossing, repair of the culverts running under the crossing, stabilization of the creek bed with gabion drop structures, and creation of wetland areas upstream and downstream of the crossing. • Phase 2 includes installation of a temporary irrigation system, planting of native California wetland and upland plant species, including trees, shrubs, cuttings; hydroseeding and providing and all other landscaping and revegetation tasks as required to complete the project. The roadway and wetlands construction tasks pose some difficulties as much of the work Will occur in the creek bed necessitating surface water control and dewatering. Water quality protection measures will need to be implemented during the duration of the project In addition to difficulties that could be triggered by the approaching rainy season, construction prohibitions exist from April 1 to September 30 to accommodate the nesting season for certain endangered bird species. Therefore, October 151 would have been the best time to begin this construction to try.to avoid these impacts. Per the Contract Specifications the Contractor would have 75 consecutive working days to complete the work. Funding from the Buck Gully Restoration grant provides $85,000 for this project: $17,000 has already been spent on engineering design services. It is likely that the grant funds will be lost as the project will now not be built before the grant deadline of March 31, 2007. Staff will recommend that construction funding be included in next fiscal year's CIP. The project would be rebid in July 2007 so that construction could begin on October 15r. Staff expects that more contractors will bid on the project if the construction is less likely to be impacted by the rain season, and that the cost for the project will be significantly below the GCI bid.
