Bids & Awards 2b. 2/4/82 DATE February 2, 1982 SUBJECT AUTHORIZE AWARD OF CONTRACT FOR THE LANDFILL GAS UTILIZATION PROJECT, DSP 3639. APPROVE EXPENDITURE OF FUNDS TYPE OF ACTION AUTHORIZE CONTRACT APPROVE FUNDS SUBMITTED BY Steve McDonald INITIATING DEPT./DIV. Engineering Division BAC KGROUND Bid advertising for construction of the Landfill Gas (LFG) Project began January 15, 1982. Four bids were received February 1, 1982. A low bid of $96,502 was submitted by Amos and Andrews, Inc. The engineer1s estimate is $148,000. A tabulation of bids is attached (Exhibit A). Unless otherwise indicated all followinq $ figures are expressed in 1,000. District staff estimates the total cost of the LFG Project at $281.0 (Exhibit B). This includes a potential maximum bonus of $10.0 to the contractor for early completion. Additional funds required for comple- tion of the LFG project, including construction management; equipment, and District forces are estimated at $105.0. However, approximately 29% of the current LFG project is work originally planned for the IISo1ids Conditioning Building (SCB) Repair - Phase II Projectll. Because the LFG project will be completed earl ier, it was determined expedient to bring forward the work that improves safety and that helps optimize boiler operations. Costs that can be directly assigned to the SCB repair work total $114.9. The SCB repair funds have been previously authorized. The original feasibility study for the LFG Project estimated a project cost of $200.0 (+40 to -30%). Based on the revised project total of $281.0 , the average yearly savings in using LFG is $140.0 /Yr (1982$). The total present worth savings are $1.4 million, based on a 10-year project life. RECOMMENDATION Award contract to Amos and Andrews, Inc. for the Landfill Gas Project DSP 3639. Authorize $105.0 to complete the LFG Project. and authorize expenditure of $114.9 from previously approved SCB funds.

DOLAN POSITI N ~PER General Manager-Chief Engineer SUBJECT AUTHORIZE DESIGN OF THRUST BLOCKS AND VACUUM REL1EF VALVES FOR PROTECTION OF THE OUTFALL AND AUTHORIZE $30,000 FROM SEW~R CONSTRUCTION FUND, DP 3637 NO. IV. Engl neen ng 1 2/4/82 1/18/82 DATE TYPE OF ACTION AUTHORIZE FUNDS SUBMITTED BY Lloyd Smith INITIATING DEPT./DIV. Engineering Division ISSUE Thrust Blocks and vacuum relief valves are required to protect the treatment plant outfall under pumped flow conditions. BACKGROUND The treatment plant outfall is capable of discharging up to 150 MGD under pumped flow conditons; however, the present gravity flow capacity is 60 to 70 MGD depending on tidal conditions. Presently the higher discharge rates would be used only during peak flow events after the holding basins are full. In the near future peak daily flows will require pumping to the outfall. The thrust blocks are required at each of the bends in the outfall to restrain the pipe during high flows. The vacuum relief valves are required to protect the outfall in the event of a pump/power failure under pumped flow conditions. These two requirements have resulted from work by Metcalf & Eddy. The design will be completed by the District staff. This project is not a line item in the 5-year capital expenditure plan; however, it can be accommodated using the allowance for treatment plant projects. It will be included in the next revision to the plan. RECOMMENDATION Authorize $30,000 from sewer construction funds for the design of thrust blocks and vacuum relief valves for protection of the outfall, DP 3637.
