Belcher, Senior Engineer INITIATING DEPTIt>IV Plant Operations/Maintenance/Maintenance Engineering ISSUE: On August 7, 1998, sealed bids were received and opened for construction of the Sludge Blending Tank Overflow Drain Realignment Project, DP 6123. The Board of Directors must authorize award of the contract or reject bids within 30 days of the bid opening. Board authorization is required for contingency allocations of more than $25,000. BACKGROUND: The primary and secondary sludge is blended and stored in two tanks. The overflows from these tanks enter a drainage system, which also serves the basement of the new Maintenance and Reliability Center (MARC). The drainage system is not adequate to handle sludge overflows without causing possible overflows in the MARC basement drains. This project will re-route the overflows from the sludge tanks to a drainage system with adequate capacity. Plans and specifications were prepared by Plant Operations Department. The Engineer's Estimate for the construction cost was $60,000. The project was advertised on July 13 and July 29, 1998. Six bids, ranging from a low of $63,764 to a high of $76,546, were received and publicly opened on August 7, 1998. A summary of these bids is shown in Attachment 2. The Purchasing Section conducted a commercial evaluation, and the Plant Operations Department conducted a technical evaluation of these bids, and they have determined that NV Heathorn, Incorporated, is the lowest responsible bidder with a bid amount of $63,764. The allocation of funds required to complete this project, as shown in Attachment 3, is $75,000. The total estimated project cost is $100,000. This project was not included in the fiscal year 1998-99 Capital Improvement Budget (CIB). Staff has conducted a cash flow evaluation of the Sewer Construction Fund and concluded that adequate funds are available for this project.

Approval of this project will establish the Board of Directors' independent finding that this project is exempt from CECA. RECOMMENDATION: Authorize award of a construction contract in the amount of $63,764 for the construction of the Sludge Blending Tank Overflow Drain Realignment Project (DP 6123) to NV Heathorn, Incorporated, the lowest responsible bidder.

Pearl, Plant Maintenance Div. Mgr. INITIAllNG DEPTJDlV Plant Operations Department/Maintenance Division ISSUE: Authorization by the Board of Directors is required for allocations from the Collection System Program Contingency Account in amounts greater than $25,000. BACKGROUND: The existing landscaping at the San Ramon Pumping Station has been in place for more than 22 years. In response to direction from the Board of Directors, a phased plan has been designed to improve the overall appearance of the property, with the focus of the work being on the east, or street side. The common theme is to tone down the institutional appearance of the site, while maintaining the necessary security for the Pumping Station's facilities. An allocation of $35,000 is requested to cover the cost of this work, which will provide improvements in the overall appearance of the facility. The work is presently planned to be done in four phases and includes replacement of the front fencing and gates with an ornamental iron fence and gate, which will be more attractive, while allowing the public and law enforcement to see into the station compound. Planters and walkway improvements are being considered to present a softer, less industrial appearance. Additional work will be done on the driveway, replacing the asphalt with interlocking pavers and constructing the interior paths with a similar material. Again, the effect will be to make the site blend in with the rest of the community. The front plants, which are junipers, will be broken up with large boulders and additional planting, reducing the bareness and providing a unified theme from one end of the property to the other. Additional perennial plants will be added. The work is planned to take advantage of existing landscaping features, which is the most cost- effective approach, and which will meld with upcoming maintenance work at the Pumping Station. We continue to maintain the landscaping currently in place, utilizing both District and specialty contractor services.
