As required by the agreement, the .Owner received three bids for the work on January 13, 2003 for $224,369, $386,438 and $402,200. The low bid is about $100,000 higher than. the Owner's previous estimate. A re- authorization by the City Council is needed to increase the previously authorized expenditure to cover the bid increase and contingency. 2. BACKGROUND In 1938, the City of Petaluma installed a 12 -inch sewer pipeline from the end of Water Street to the intersection of and Second Street. This pipeline travels beneath the wooden decking of the Great Petaluma Mill and was originally installed under an easement granted by the owner of the Mill. The pipe is attached to the retaining wall located beneath the wooden decking. Over the years, the bank beneath a portion of the deck (near the Apple Box) has been slipping towards, the river, pulling the deck with it. Studies conducted by the owner of the Great Petaluma Mill (Owner) have concluded that the existing concrete sea wall under theL deck is in good condition,_ This conclusion is primarily based on &physical condition of the wall. No drawings or records of its construction. exist. The problem occurs where the existing retaining, wall ends (near the Apple Box). A wooden retaining structure at this located has deteriorated to the point it can no longer hold back the riverbank. Therefore, the Owner plans to replace the wooden, retaining wall with a new concrete retaining wall that will extend from the existing concrete retaining wall, plus repair of the deck and walkway. With repair of the wooden decking and construction of a new retaining wall set to occur, this is an opportune time for the City to remove and replace the 112 -inch sanitary sewer pipeline. ® Under the proposed. agreement, the City will contract with the Owner for removal of the existing 12 -inch sanitary sewer pipeline, installation of a new 12 -inch sanitary sewer pipeline, and 50% of the cost for construction of the new concrete retaining wall. The location of the pipeline is shown on Exhibit A. The new 12 -inch sanitary sewer pipeline will be mounted on the existing and new "retaining walls. The Owner will also grant an easement to the City for routing the pipeline in the Owner's property and for operation and maintenance of the pipeline. The proposed reimbursement agreement is provided under Exhibit B. Contracting with the Owner to perform the sewer main replacement in conjunction with the Owner's planned improvements has a number of benefits: 1'Y Cost. Reduction. All the work will be performed by one contractor, which should reduce costs: 2) Minimize Public Impacts. Replacing the.sewer pipeline with the Owner's project eliminates the need for the City to. remove and replace the deck and walkway, which the City would _have to do if it were to replace the sewer pipeline in the future after the completion,of the Mill's improvements. This approach minimizes`publicimpacts and reduces project costs. During the. process, without: the availability of the complete construction plans, the Owner obtained :a preliminary cost estimate from his contractor for the replacement of the existing: sewer. line for $126 The reimbursement agreement presented to the City Council on November 18, 2002'was based on the Owner's preliminary cost estimate. After the final, construction plans and specifications for the sewer line were completed in December 2002, the Owner received three bids for the work for $224,3:69, $386. . 438 and $402,000. The bids were higher than the preliminary cost estimate because no detailed plans and specifications were available , for the contractor to base his original cost estimate on. During the bid process, the contractors examined the plans and specifications closely, and realized that they had to perform more work than they originally thought. ALTERNATIVES Alternatives for this project include: 1: Reject the reimbursement agreement.and take no action at this time. Replace ary the sanit _ sewer main . at a fu ture, date. 2. Approve lhe, resolution re- authorizing the City Manager to execute the reimbursement with G&W/ Great Petaluma Mill, LLC for the replacement of the.sanitary sewer main along the wharf between Western Avenue and B Street. 4. FINANCIAL IMPACTS The revised estimated construction cost for the.sanitary sewer main replacement including project contingency and. 50 of the. cost of the new retaining wall is $3.98;564. The previous cost estimate in November 2002 was $301,000. The project will be funded by°the Wastewater Enterprise Funds under Project 9869. A comparison of1he prior authorization and.the new authorization is shown on Exhibit C. This project is 2 programmed in the Department of Water Resources & Conservations FY 02 -03 budget. The total FY 02 -03 budget is $450,000 (this includes design, construction, construction management, and contingency), which is sufficient to cover the re- authorization amount of $418,564. 5.. CONCLUSION Following there- authorization, the City Manager will execute the reimbursement agreement with G &W/ Great Petaluma Mill, LLC: 6. OUTCOMES OR PERFORMANCE MEASUREMENTS THAT WILL IDENTIFY SUCCESS OR COMPLETION: Successful replacement of the sanitary sewer pipeline and construction of the new retaining wall. 7.
