ADVISE THE BOARD OF THE CLOSE OUT OF THE PREAERATION ODOR CONTROL PROJECT (DP 7108) DATE November 7, 1995 TYPE OF ACTION SUBJECT INFORMATIONAL SUBMITTED BY Munawar Husain, Associate Engineer INITIATING DEPT.lDIV. Engineering Department/ Plant En ineerin Division ISSUE: All work has been completed on the Preaeration Odor Control project, and this project can now be closed out. BACKGROUND: Work completed under this project provides odor control in the primary area for the preaeration tanks, distribution channels, effluent channels, and the chemical feed building. A new Calvert scrubber unit has been added along with associated tanks, equipment, fiberglass ducts, and piping. The tanks and channels have been provided with removable flat aluminum covers that contain the foul air beneath the covers. The foul air is conveyed in fiberglass ducts to the scrubber unit where the odors are removed prior to release to the atmosphere. Details of the project were included in the Fiscal Year 1993-94 Capital Improvement Budget (CIB). The construction contract was awarded to Monterey Mechanical Company of Oakland, California, on July 15, 1993, by the District Board of Directors. The contractor was issued a Notice to Proceed on August 18, 1993. The contract completion date was August 31, 1994. The contract work was completed on time, with the District taking beneficial occupancy of the new facilities on August 26, 1994. Monterey Mechanical Company's original construction contract was for $850,000. There were 15 change orders issued on the project totalling $36,285. The total contract amount paid to Monterey Mechanical Company was $886,285. The total budget for the project was $1,343,000. The total completed project cost is $1,273,000. Staff is closing out the project account, which will result in $70,000 being returned to the Treatment Plant Program. RECOMMENDATION: This item is presented to the Board of Directors for information. No action is necessary. RE~EWEDANDRECOMMENDEDFORBOARDAcnON MH RAB 1302A-7/91 RSK {);[iJ WEB ~ ~ PAGE OF 2 BOARD MEETING OF November 14, 1995 NO. 6. BIDS AND AWARDS a. SUBJECT DATE November 3, 1995 REJECT All BIDS FOR PURCHASE OF REDUNDANT CASCADE TYPE OF ACTION UNINTERRUPTIBlE POWER SUPPLY (UPS) REJECT BIDS SUBMITTED BY INITIATING DEPT./DIV. Cheri Arstani, Principal Buyer Ad m in istrative/Purc hasing ISSUE: On October 18, 1995 sealed bids were received and opened for the purchase of one redundant cascade uninterruptible power supply (UPS) for Capital Improvement Project No. 6110. The Board of Directors must award purchase or reject all bids within 60 days. BACKGROUND: The District treatment plant's main UPS supplies continuous electrical power to critical process control equipment, radio and telephone systems, MIS computer equipment, and the new network server even during a complete power failure. The UPS has been well maintained and has operated continuously for nearly 20 years with minimal downtime. However, replacement parts are now obsolete and no longer available, and the last of on-hand spare parts have been used. Recent UPS failures have caused subsequent failures to many of the critical loads. Because of this, the UPS is no longer redundant or reliable, and it is necessary to replace the UPS. Bids were sent to four suppliers. Two bids were received and publicly opened on October 18, 1995, as follows: Cyberex International Power $102,728.60 91,952.00 Technical evaluation revealed that by proceeding with the purchase and installation of the UPS as bid, an unanticipated construction expense and a potential safety hazard would result. Technological changes in the UPS industry have favored reducing the input current requirement, which increases the input voltage and the number of batteries required. In our case, the number of batteries increased from 20 to 108 cells. The size and configuration of the battery racks would create a safety hazard for maintenance personnel if installed in the existing battery room. Expansion of the battery room would be a costly and impractical solution. By reducing the emergency backup time requirement from four hours to one and one half hours, the battery size (physical dimensions) can be reduced such that modification of the battery room would be unnecessary and safety would not be compromised. With the availability of cogeneration and standby power, the backup time would be sufficient even at full load. This change should result in an approximate equipment savings of $20,000, and more bidders may ~ GEN5f{fHIEF ENG. /fJJ5 )L ROGER .

ENGINEERING a. SUBJECT ADOPT A RESOLUTION APPROVING DIRECTIONAL DRILLING DEMONSTRATION PROJECT AND AUTHORIZE THE GENERAL MANAGER-CHIEF ENGINEER TO EXECUTE A CONTRACT WITH UTI LX CORPORATION FOR THE MARTINEZ DOWNTOWN TRUNK SEWER PROJECT, DISTRICT PROJECT NO. 4950 DATE November 8, 1995 TYPE OF ACTION AUTHORIZE RESOLUTION/ AUTHORIZE AGREEMENT SUBMITTED BY Curtis W. Swanson Principal Engineer INITIATING DEPT./DIV. Engineering Department/ Infrastructure Division ISSUE: Board authorization is required for the General Manager-Chief Engineer to execute construction contracts over $10,000 and to exempt projects from public bidding for field testing purposes. BACKGROUND: The trunk sewer serving the eastern part of downtown Martinez is deteriorated and undercapacity. The sewer was installed in the 1920's. Overflows from this sewer occurred during the winter of 1995 near Court, Jones and Pine streets. Currently, the District is designing a new 3,500-foot-long trunk sewer that will be constructed during 1996. However, staff is concerned that additional overflows may occur during the 1996 winter season. Staff feels an urgency to protect the neighborhood and proposes to install a 550-foot- long section of new parallel sewer to alleviate a hydraulic bottleneck before the rainy season. Staff determined that installation of a new sewer along a new alignment using a trenchless technology construction method called directional drilling is the most practical alternative for this project because of the potential for minimizing construction and traffic impacts on the neighborhood. The new parallel sewer will be installed in two phases. An 8-inch sewer will be installed by directional drilling during 1995. (An 8-inch sewer is the maximum size that can be installed by directional drilling.) This sewer will be enlarged to 12-inch diameter by pipe bursting during 1996. This approach provides near-term overflow protection, eliminates open- cut construction, and allows an opportunity to use newer directional drilling technology. The project location is shown in Attachment 1. In 1988 and 1989, the District conducted demonstration projects with Flow Mole Corporation involving directional drilling. While the results of these demonstration projects were generally favorable, there were problems maintaining vertical alignment using the directional drilling technology. During the last six years, there have been significant improvements and developments in the UTILX (successor to Flow Mole Corporation) directional drilling technology. Staff is proposing to conduct a new and separate demonstration project using improved directional drilling technology developed by UTILX Corporation of Kent, Washington. REVIEWED AND RECOMMENDED FOR BOARD ACTION INIT8'\r; ~DIV 1302A-7/91 141 ~ CWS JSM RAB ADOPT A RESOLUTION APPROVING DIRECTIONAL DRILLING DEMONSTRATION PROJECT AND AUTHORIZE THE GENERAL MANAGER-CHIEF ENGINEER TO EXECUTE A CONTRACT WITH UTILX CORPORATION FOR THE MARTINEZ DOWNTOWN TRUNK SEWER PROJECT, DISTRICT PROJECT NO. 4950 SUBJECT PAGE DATE 2 OF 5 November 8, 1995 Earlier this year, the District conducted adirectional drilling demonstration under the Knox Drive Sewer Project, DP 4602. This demonstration project used proprietary directional drilling equipment and methods developed by Underground Construction Company, Inc. Although this project was eventually successful, there were installation problems associated with differing site conditions and the drilling fluid system. Staff has made changes or improvements to the proposed project to address these types of problems. These improvements include more extensive specifications and shop drawing requirements for pipe materials, reaming operations, and monitoring and operation of the drilling fluid system. The directional drilling system now used by UTILX Corporation is different in several aspects from the directional drilling systems used in the previous demonstration projects, including the project conducted earlier this year. The principal differences are: 1) a different shaped boring head, and 2) an enhanced control system within the boring head. The new control system allows installation of sewers on a 1 percent slope. Previously, District staff has used directional drilling only on sewers with slopes greater than 2 percent. Demonstration projects, in general, have risks associated with them. The directional drilling technology has advanced to a point where the risks associated with this project have been minimized. The proposed method has a significant installation advantage by limiting impacts to the travelling public and neighborhood businesses. Staff concludes that there is sufficient justification to try this improved method of installing gravity sewers by drilling, rather than open cut. Staff conducted a review of potential firms capable of performing this project and has determined that only UTILX Corporation has the capability to perform the proposed work with directional drilling. Other firms use directional drilling equipment with less sophisticated control and guidance systems. These firms are not able to install a gravity sewer with a 1 percent slope. Exemption from bidding for this project is allowed under Public Contract's Code, Section 3400. Staff believes that this project is exempt from bidding as a field test or experimental project because: 1) sewer pipelines have not been installed at the District using the improved directional drilling technology, and 2) one of the primary objectives of the project is to demonstrate the applicability of using directional drilling technology on future sewer construction projects. 13028-7/91 ADOPT A RESOLUTION APPROVING DIRECTIONAL DRILLING DEMONSTRATION PROJECT AND AUTHORIZE THE GENERAL MANAGER-CHIEF ENGINEER TO EXECUTE A CONTRACT WITH UTILX CORPORATION FOR THE MARTINEZ DOWNTOWN TRUNK SEWER PROJECT, DISTRICT PROJECT NO. 4950 SUBJECT PAGE DATE 3 OF 5 November 8, 1995 A unit price contract with a cost ceiling of $49,500 has been negotiated with UTILX Corporation. The scope of this contract includes mobilization and demobilization, installation of approximately 550 feet of 8-inch sewer by directional drilling, modification of two manholes, and temporary bypass pumping. The total estimated construction cost for the demonstration project will be $83,000. This estimate includes the work by UTILX Corporation, staff labor for public information, construction management and inspection, and a contingency for unforeseen conditions. A summary of these project costs is presented in Attachment 2. Construction of the Martinez Downtown Trunk Sewer Project is included in the fiscal year 1995-96 Capital Improvement Budget (CIB) on pages CS-51 through CS-53. The total project cost included in the CIB is $1,986,000. This demonstration project is a part of the Martinez Downtown Trunk Sewer Project. This project has been evaluated by staff, and it has been determined to be exempt from the California Environmental Quality Act (CEQA) under District CEQA Guidelines, Section 18.2, because it involves only minor alterations of existing facilities with negligible or no expansion of dry-weather flow capacity. Board of Directors' approval of this project will constitute a finding that the project is exempt from CEQA. RECOMMENDATION: 1 . Adopt a resolution finding that pursuant to Public Contract Code, Section 3400 (b) that entering into a contract for use of UTILX Corporation's directional drilling technology is required so that the District may perform a field test or experiment to determine the suitability of the technology for future District use. 2.

ENGINEERING b. SUBJECT DATE November 8, 1995 AUTHORIZE THE GENERAL MANAGER-CHIEF ENGINEER TO ALLOCATE $35,000 FROM THE COLLECTION SYSTEM PROGRAM CONTINGENCY ACCOUNT FOR THE LAS TRAMPAS CREEK STORM DAMAGE REPAIR PROJECT, DP 5080 TYPE OF ACTION AUTHORIZE ALLOCATION SUBMITTED BY Curtis W. Swanson Principal Engineer INITIATING DEPT./DIV. Engineering Department/ Infrastructure Division ISSUE: The Board must authorize allocations greater than $25,000 from the Capital Improvement Program contingency accounts. BACKGROUND: The interceptor sewer serving Orinda, Moraga, and Lafayette is located along the former Sacramento Northern Railroad right of way in Lafayette and Moraga. The interceptor sewer is reinforced concrete pipe ranging in size from 27 inches to 45 inches in diameter. Certain reaches of the interceptor sewer are located next to Las Trampas Creek. During the winter of 1995, high flows in Las Trampas Creek caused erosion of the creek bank at three locations. Continued erosion at these three locations threatens to undermine the interceptor sewer. Under an initial allocation of $25,000 from the General Manager-Chief Engineer, preliminary engineering and interim stabilization of the erosion areas have been accomplished prior to the upcoming winter. An additional allocation is necessary to complete geotechnical engineering and design of the long-term creek bank stabilization to protect the District interceptor sewer. An allocation of $35,000 from the Collection System Program Contingency Account is requested for this effort. A summary of the estimated design costs is listed in Attachment 1. The estimated total project cost will range from $160,000 to $200,000. RECOMMENDATION: Authorize the General Manager-Chief Engineer to allocate $35,000 from the Collection System Program Contingency Account for the Las Trampas Creek Storm Damage Repair Project, DP 5080.

HUMAN RESOURCES a. SUBJECT DATE November 3, 1995 DIRECT STAFF TO SECURE THE SERVICES OF AN ARBITRATOR IN ACCORDANCE WITH THE DISTRICT'S GRIEVANCE APPEAL PROCEDURES TYPE OF ACTION HUMAN RESOURCES SUBMITTED BY Paul Morsen, Deputy General Manager INITIATING DEPT./DIV. Administrative ISSUE: In accordance with the Memorandum of Understanding (M.O.U.) between the District and the Central Contra Costa Sanitary District Employees' Association, Public Employees' Union, Local No. One, the Board of Directors shall employ an arbitrator to render a recommendation when grievances are appealed to the Board level. BACKGROUND: Mr. Russell Leavitt, Planning Assistant, applied for a promotional reclassification under the M.O.U., Article III, Section 7.1, Emolovee Reclassification Reauests. Following staff review, Ms. Chris Casey, a consultant for Shannon & Associates specializing in classification and recruitment, was engaged to make a recommendation regarding Mr. Leavitt's request. After considerable study, Ms. Casey found: (1) Mr. Leavitt was working within the scope of his classification; (2) the salary of the Planning Assistant is appropriate for the assigned duties and responsibilities; and (3) the title of Planning Assistant is outdated and could be modified. Mr. Leavitt filed an appeal under the relevant grievance procedures of the M.O.U. to the General Manager-Chief Engineer. The General Manager-Chief Engineer conducted a hearing and upheld the recommendation of the consultant. Consequently, Mr. Leavitt is now appealing this matter to the Board in accordance with the M.O.U., Article III, Section 2.4. In matters that are appealed to the Board, the M.O.U. reads as follows: A. "In the event such differences are not settled and the grievant desires the grievance.to be considered further, it shall be presented, in writing, to the Secretary of the District within five (5) days of receipt of the General Manager-Chief Engineer's decision. The Secretary shall calendar the agenda item at the next regularly scheduled Board Meeting in keeping with established guidelines for calendaring an agenda item." B. "The Board shall employ a neutral third party to hear the appeal and to recommend action to the Board." C. "The Board may adopt, reject, or modify the recommendation of the Board-appointed neutral third party. The decision of the Board is the final action of the District." RECOMMENDATION: Authorize staff to secure the services of an arbitrator in accordance with the District's appeal procedures in the grievance of Planning Assistant Russell Leavitt.
