Recommended Action Adopt a Resolution approving the plans and specifications and authorizing the Secretary to the Board to advertise and receive bids for the Bolero Pressure Reducing Station Replacement, Project No. 5020. Executive Summary The Bolero Pressure Reducing Station is one of Carlsbad Municipal Water District's (CMWD) 74 pressure reducing stations for the potable water distribution system. The buried concrete pressure reducing station was built in 1977 and has reached the end of its useful life and is in need of replacement. The defects include cracked and spalling concrete and exposed rebar. To coordinate distribution system upgrade efforts, the pipe and appurtenances inside the concrete vault will also be replaced due to age. Service to customers will be maintained during construction. Staff recommends approval of the project plans and specification, and authorization to advertise for construction bids of Project No. 5020. Discussion CMWD's water distribution system is divided into 17 pressure zones. A pressure reducing station is located between two different pressure zones. The station contains valves and appurtenances which maintain a downstream pressure in the system. The Bolero Pressure Reducing Station is located on Bolero Street, within the public right-of-way. The demolition of the existing vault and construction of the new vault will require a shutdown of the 12-inch Asbestos Concrete Pipe (ACP) for the duration of construction.In order to prepare for this work, CMWD has installed an insertion valve to isolate the vault location and will allow water service to customers to be maintained during construction. The project will require the existing vault and appurtenances to be removed. A new cast-in- place concrete vault will be poured and new appurtenances and concrete mortar lined and coated (CMLC) steel pipe will be installed. All existing electrical and SCADA connections will be reestablished after the installation of the new equipment. The existing 12-inch ACP will be removed and replaced with 12-inch polyvinyl chloride (PVC)pipe to the nearest joint upstream and downstream of the vault. New appurtenances will be procured and installed under this project. Fiscal Analysis The engineer's estimate of the construction cost of the Bolero Pressure Reducing Station Replacement, Project No. 5020 is $216,000. The project will be funded by the Water Capital Replacement Fund. A summary of estimated construction costs and available funds is shown below. BOLERO PRESSURE REDUCING STATION REPLACEMENT, ESTIMATED COSTSPROJECT NO. 5020 Construction Contract (Engineer's Estimate)$216,000 Construction Contingency)$30,000 Construction Management, Inspection, and Material Testing $32,000 TOTAL ESTIMATED CONSTRUCTION COSTS $278,000 Current Appropriation-Pressure Reducing Station Program,CIP No. 5020 $661,732 Current Expenditures/Encumbrances-Pressure Reducing Station Program, CIPNo. 5020 $0 'TOTAL FUNDS AVAILABLE PHASE III PIPELINE PROGRAM, CIP NO. 5208 $661,732 ADDITIONAL APPROPRIATION ANTICIPATED FOR CONSTRUCTION $0 'Engineering staff typically recommends that an allowance of 10 percent of the construction cost be budgeted for potential change orders on projects of average size and complexity. Since this is a smaller than average project,staff recommends using a fixed dollar amount to ensure that adequate funds are available to address unforeseen issues that may be encountered during construction. The fixed dollar amount results in a contingency budget that is greater than 10 percent. Next Steps A Construction Contract Request for Bids will be advertised on the city bid site. Staff will then return to the Board to recommend awarding a contract to the lowest responsive and responsible bidder.
