LOPEZ, CAPITAL PROJECTS DIVISION MANAGER GREG NORBY, DEPUTY GENERAL MANAGER - OPERATIONS Roger S. Bailey Kenton L. Alm General Manager District Counsel ISSUE On August 16, 2023, three bids were received for the construction of the Martinez Urgent Force Main Replacement, District Project 100066 (Project). The Board of Directors (Board) must consider award of the construction contract or reject bids within 50 days of the bid opening. Board authorization is also required for the General Manager to amend a professional engineering services agreement above September 7, 2023 Regular Board Meeting Agenda Packet - Page 57 of 160 Page 2 of 8 $200,000 and transfer funds over $500,000 within the Capital Improvement Program for individual project budgets. BACKGROUND The existing dual 20 -inch cement mortar -lined and coated steel force mains from the Martinez Pumping Station were constructed in 1968 and convey raw wastewater to a discharge structure located within the Martinez Refining Company's (MRC) property. Each force main is roughly a mile in length and situated on easements just North of Marina Vista Avenue in Martinez and along the Union Pacific Railroad's (UPRR) right-of-way prior to entering the MRC secured facility as shown in Attachment 1 -Project Location Map. I n November 2022, Engineering staff was notified of a small leak at one of the force mains on the UPRR right-of-way. Operations staff quickly responded and stopped the leak by shutting down the force main and draining the sewage within the pipeline back to the Martinez Pumping Station wet well. While the force main was empty, staff CCTV'd the upper portion of the pipeline near the discharge structure, including the failed pipe location. Based on the video and external inspection, staff determined that the force main has various levels of corrosion with the most severe being observed internally at the top of the pipeline for the last 300 feet. This type of corrosion is common for force mains that experience hydrogen sulfide gas pockets or are not fully filled with wastewater, causing sulfuric acid build-up that deteriorates the cement lining and steel pipe. Capital Projects obtained a contractor to make an urgent repair that involved steel mesh, mortar, and a carbon -reinforced fiber wrap. The repair was successful, and Operations returned the force main to service before several large winter storms. Operations will routinely open both force mains during the wet weather season for purposes of redundancy and to reduce flow velocities within the pipelines. The force mains can experience a large range of flows from 1.0 million gallons per day (MGD) during dry weather to over 12 MGD during peak wet weather events. After the repair and additional inspection of the aerial crossings, staff identified a second failing location that has severe corrosion on the exterior of the pipe. This second location could not be easily seen on the initial inspection due to difficulty in accessing the aerial crossing in the refinery. Therefore, the force main has been turned off again until a contractor can be hired to perform a more extensive repair and/or a full temporary replacement of the aerial crossing. Due to urgency of the situation, staff reached out to Carollo Engineers, Inc. (Carollo) to advise and provide engineering services to permanently replace the corroded force main sections. Carollo is currently working at the Martinez Pumping Station and at the MRC refinery for the Fairview Pumping Station replacement as the construction manager. After reviewing several project alternatives, staff decided that the best alternative was to remove and replace the last 650 feet of both existing force mains. This option will remove the medium to more severe corroded sections and replace all of the force mains on UPRR's right- of-way and MRC's property. The new pipeline is designed using PVC, and will be installed within steel casings for the aerial crossings. Coordinating and obtaining permits with UPRR has been a slow process, and staff has been diligent with providing notifications and anticipates getting final conditions once a general contractor is hired and on site to investigate the field conditions and utilities. The location of the force mains adjacent to the railroads and nearby utilities makes the replacement work very complicated and poses various construction challenges and risks. These challenges include limited access for replacing the aerial crossing and building the new pipe supports. The risks include working near high-pressure gas lines, Kinder Morgan pipeline, and other utilities. Staff has been coordinating with the utilities and pipeline owners to safely perform the construction activities. A careful and highly qualified pipeline contractor with relevant experience is needed to perform the construction work and within the Project timelines. Staff is recommending the Project to be completed in two milestones. The first is for repairs or a temporary pipeline to be installed so that the force mains care is reliable this upcoming wet weather season. And the second milestone is to complete the permanent replacement by July of next year September 7, 2023 Regular Board Meeting Agenda Packet - Page 58 of 160 Page 3 of 8 Based on the Project complexity, Central San conducted a formal pre -qualification review of general contractors, receiving statements of pre -qualifications from five interested general contractors: Cratus, I nc., J MB Construction, I nc. (J MB), McGuire and Hester, Mountain Cascade, I nc., and Steve P. Rados, I nc. The solicitation was publicly advertised on PlanetB ids and shared with bidder exchanges, meeting the notification requirements for public bidding and included a draft of the plans and specifications to allow contractors to understand the challenges within the Project scope. Upon staff review, all five general contractors were approved to participate in the bidding process. Staff and Carollo prepared the bid plans and specifications for the Project. This Project was again advertised on August 2, 2023, with updated bid plans and complete list of specifications for the vendors and subcontractors. Three bids, ranging from $2,342,000 to $3,740,000, were received and opened on August 16, 2023. The Engineer's estimate for the construction is $2,500,000. Capital Projects conducted a technical and commercial review of the bids and determined that J MB is the lowest responsive and responsible bidder with a bid amount of $2,342,000. A summary of bids received is shown in Attachment 2. JMB has been pre -qualified and meets the experience, safety, and other requirements. An additive bid item was included in case temporary piping was required under the project. The Engineer's estimate for the additive item is $300,000. The additive bids ranged from $180,000 to $500,000 and JMB priced the work at $180,000. Staff recommends to include the additive item to the Project. Capital Projects staff will provide oversight and construction management of the Project. Carollo will provide technical support and engineering services, and inspection is planned to be conducted by staff or may be supplemented by one of Central San's as -needed consultants with relevant experience. Operations staff will support the Project as required to coordinate shutdowns and testing. Additional site investigations, including geotechnical work, utility locating, and potholing, are required by the contractor to finalize the design. These investigations will assist in determining the proper backfill requirements and pipeline alignment needed for the new forcemains. This activity will also help and will be coordinated with the refinery, UPRR, and all nearby utilities. California Environmental Quality Act (CEQA) Staff has concluded that this Project is exempt from CEQA under Central San's CEQA Guidelines Section 15302, since it involves replacement of existing public facilities at the same location and with the same purpose. Approval of this Project will establish the Board's independent finding that this Project is exempt from CEQA. ALTERNATIVES/CONSIDERATIONS The Board could consider the following alternatives or provide other direction: 1. Reject all bids which is not recommended. This Project will address the urgent need to replace critical sewer infrastructure. 2. The Capital Improvement Contingency account has adequate budget and could be used to fund the Project; however, it is not recommended since its early in the fiscal year and would deplete the account significantly. The proposed funding source is a program budget used for sewer renovation projects that currently has adequate projected cashflow for the sewer renovation projects planned this fiscal year and for the urgent project. FINANCIAL IMPACTS The total estimated project cost is $3,962,000, which includes staff time, consultant costs, construction contract, contingency, construction management, and other costs detailed in Attachment 3. September 7, 2023 Regular Board Meeting Agenda Packet - Page 59 of 160 Page 4 of 8 The Project was initiated under the General Manager's delegated authority for contingency projects at $200,000. The remaining $3,762,000 needed to fully fund the Project will be transferred from the Collection System Sewer Renovation - Phase 2, which has adequate funds in Fiscal Year 2023-24 at $18,500,000 as detailed on page 231 of Central San's Budget. Carollo was hired under a separate project consisting of similar work and services to the urgent force main replacements. The existing Carollo agreement is currently valued at $2,500,000, and with the proposed $400,000 revision, will increase the total value to $2,900,000. The costs will be tracked and billed separately to each individual project. COMMITTEE RECOMMENDATION The Engineering and Operations Committee was unable to discuss this subject in detail on August 14, 2023 and set a special meeting for August 21, 2023. The committee met and reviewed the item and recommends approval of the Project. RECOMMENDED BOARD ACTION Staff recommends the following Board actions: 1. Find that the Project is exempt from CEQA; 2. Award a construction contract in the amount of $2,342,000 to J MB Construction, Inc., the lowest responsive and responsible bidder, for the Martinez Urgent Force Main Replacement, District Project 100066. 3. Include additive bid item for $180,000 for temporary pipelines; 4. Authorize the General Manager to amend an existing Carollo Engineers, Inc. agreement for $400,000 to include engineering services; and 5. Transfer $3,762,000 from the Collection System Sewer Renovation -Phase 2 to fund the Project.
