HomeMy WebLinkAbout17 - Grand Canal Dredging, Eelgrass Transplant, and Rock Buttresses Contract No. 3154 - Reject All Bids RecievedJanuary 11, 1999 CITY COUNCIL AGENDA ITEM NO. 17 TO: MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: PUBLIC WORKS DEPARTMENT SUBJECT: GRAND CANAL DREDGING, EELGRASS TRANSPLANT, AND ROCK BUTTRESSES, CONTRACT NO. 3154 REJECT ALL BIDS RECEIVED RECOMMENDATIONS: 1. Approve the Plans and Specifications. 2. Reject the sole bid received. 3. Direct staff to re- budget and re- advertise the project for bids during FY 1999- 2000. DISCUSSION: At 11:00 A.M on December 22, 1998, the City Clerk opened and read the following bid for this project: TOTAL BID PRICE Low AIS Enterprises of Carpinteria, CA $212,975 The low total bid price is 12% above the Engineer's Estimate of $190,000. The low bidder, AIS Enterprises, is a newly - licensed General Engineering "A" Contractor. It appears that AIS has not completed a similar project. In addition, AIS' unit prices for dredging and material placement appear to be higher than previous projects. The Grand Canal was last dredged and the seawall embankments rebuilt in the mid 1980s. At that time, the entire length of the Canal was dredged using the clam -shell method. During the bid advertisement period, staff sent bid invitations to nineteen contractors that bid dredging projects for other Southern California agencies during 1998. Of the nineteen contractors, only AIS submitted a bid. Their total bid price is $83,000 above the $130,000 budgeted amount. Due to the lack of competitive bid response, staff contacted all of the noticed contractors that did not bid on the work to obtain an SUBJECT: REJECT THE BID RECEIVED FOR CONTRACT NO. 3154 - GRAND CANAL DREDGING, EELGRASS TRANSPLANT AND ROCK BUTTRESSES January 11, 1999 Page 2 understanding of the lack of bids. Of the seventeen firms contacted, seven contractors did not respond; three contractors were clam -shell dredgers and could not perform the required hydraulic dredge work; three contractors were busy with other commitments; one contractor had difficulty with sub - contracting the eelgrass transplant portion of the work; and the work was either too small or too big for the remaining three contractors. From the information obtained from the non - bidders, it appeared that the specified hydraulic work method desired by the Canal residents and the lack of readily available contractors contributed to the lack of bids for this project. Due to State and Federal requirements that limit all eelgrass transplant work to be performed between the months of October and February; that the re- advertisement of the project at this time for more favorable bids will not provide the contractor with sufficient time to complete the eelgrass work prior to the February 28th transplant completion deadline; that the Corps of Engineers Permit will not expire until August of year 2001; and that the California Coastal Development Permit will not expire until October of year 2000, staff recommends the project to be rebugeted and re- advertised for more favorable bids during FY 1999 -2000. BACKGROUND: Last year, while preparing the contract plans and specifications for this project, 1.5 acres of eelgrass was discovered growing along the entire canal bottom where dredging was originally planned. Although staff maintained that the work is maintenance in scope, the City is required by the US Corps of Engineers, the National Marine Fisheries Service, the California Coastal Commission, and the California Department of Fish and Game to develop and implement a preliminary and a final mitigation plan to mitigate /transplant all eelgrass disturbed and/or removed by the dredging work to the extent that there will not be any net loss of eelgrass 5 years after the mitigation work has been completed. Since the cost of eelgrass transplant and maintenance is substantial, staff negotiated with the State and Federal agencies to explore alternatives to reduce the scope and cost of the required and unbudgeted eelgrass removal and transplant work in the Canal. Subsequently, staff re- surveyed the Canal after the 1998 El Nino storms and found the canal bottom from the first alley south of North Bay Front to just north of the Park Avenue Bridge already has acceptable depths and therefore will not require any dredging nor eelgrass transplant work. The proposed work include the hydraulic dredging of 2,700 cubic yards of existing Canal material from the most northerly 100 feet of the Canal and approximately from the Park Avenue Bridge to South Bay Front; the rebuilding of seawall embankments along both sides of the Canal using the dredged material and 2,300 cubic yards of imported sand provided at no cost by the County of Orange from their Bayside Drive HarborMaster Lifeguards Station beach; the transplanting of 27,500 square feet of eelgrass impacted by the dredging work; and the import and placement of 650 tons of f:\ users\ pbw \shared\council \fy98 -99\ an -11 \grand canal c- 3154.doc 0 SUBJECT: REJECT ALL BIDS RECEIVED FOR CONTRACT NO. 3154 - GRAND CANAL DREDGING, EELGRASS TRANSPLANT AND ROCK BUTTRESSES January 11, 1999 Page 3 rock to reconstruct and construct rock buttresses at all four Canal seawall corners and at Crab Point.
