AGENDA REVIEW No changes. PUBLIC COMMENTS None. ADMINISTRATIVE BUSINESS 1. Report regarding Resolution No. 44-2019 awarding a construction contract to Flatiron West, Inc. of Benicia, California for the WQCP Effluent Storage Pond Liner Replacement (Project No. ss 1704) in an amount not to exceed $716,000, authorize a total construction budget of $859,200, and approve Budget Amendment Number 19.048. (Brian Schumacker, Superintendent and Peter Vorametsanti, Swinerton) Peter Vorametsanti, with Swinerton Management & Consulting, presented the report and indicated that South San Francisco -San Bruno Water Quality Control Plant (WQCP) is a critical facility that provides secondary wastewater treatment for the Cities of South San Francisco and San Bruno, Town of Colma, and portions of City of Daly City. The total population served by the WQCP is roughly 110,000. Further, the North Bayside System Unit (NBSU) is a joint powers authority composed of the cities of South San Francisco, San Bruno, Burlingame, and Millbrae, and the San Francisco Airport. Treated wastewater from the NBSU agencies undergoes dechlorination and then disposal to the deep -water channel in San Francisco Bay. Treated effluent discharge rates to the Bay are limited to 64 million gallons per day (MGD) because of pipeline capacity. Due to higher influent flows caused by wet weather, Plant operators temporarily store a portion of the treated effluent in the effluent storage basin. Contractors finished construction of this storage basin in 2004. The effluent storage basin has a capacity of 7 million gallons and a surface area of approximately 145,000 square feet. During construction in 2004, contractors lined the effluent storage basin with a flexible, impermeable geomembrane to control seepage into underlying soils per design specifications. The Water Board requires that that City replace this aging liner because the original liner installed in 2004 has many areas that have begun to show deterioration. The City commissioned a replacement design that consists of providing and installing a replacement reinforced polyester geomembrane liner, and making minor spot repairs to the basin's earthen berm. The construction contract allows 80 working days to complete this work to accommodate completion of the work before the onset of the next wet season when the basin must be returned to service. Mr. Vorametsanti indicated that staff advertised a notice inviting bids for the project on February 28, 2019. To generate interest in this bidding opportunity, staff reached out to 46 potential bidders and fabricators including Anderson Pacific, BTL Liner, Environmental Construction, Flatiron, Fab - Seal, Graniterock, Layfield Group, Seaman Corp., and Western Environmental Liner. Swinerton hosted a non -mandatory pre-bid conference at the job site on March 12, 2019. Three interested potential bidders attended. On April 26, 2019, the City received one responsive and responsible bid from Flatiron West, Inc. of Benicia, California. The low level of response appears to be due to the specialized nature of this work, the relatively small size of the job as compared to the landfill cell lining these firms specialize in, and the difficulty of coordinating construction on an active treatment plant. He indicated that Flatiron West, Inc. is currently on site working on the Wet Weather Digester Expansion Project. Staff expects that Flatiron West will professionally deliver this construction project. Public Works contracts are ordinarily awarded to the lowest responsible bidder whose bid is responsive to the solicitation (Public Contract Code §20166). Staff verified the bidder's qualifications and contractor's license with the Contractor's Licensing Board and found it to be in good standing. The liner replacement project funded from the Sewer Enterprise Fund; therefore, there are no Disadvantaged Business Enterprise (DBE) requirements. The contract budget is $716,000 with a construction contingency (20%) of $143,200 for a total budget of $859,200. The project is included in the City of South San Francisco's Fiscal Year 2018- 19 Capital Improvement Program (Project No. ss 1704) and funded by the Sewer Enterprise Fund. Staff requested the approval of Budget Amendment number 19.048 to transfer an additional $460,000 from the Sewer Enterprise Fund into the project budget to cover this project. The City's adopted sewer rate plan provides revenue to accommodate this transfer. Councilmember Nagales indicated that this project is relatively small and therefore the City received one bid due to the scope of the project according to the staff report presented. Mr. Vorametsanti indicated that projects of this type are normally larger and due to the scope of the project, only one bid was received. Councilmember Nicolas inquired about the number of wastewater treatment facilities in the Bay Area and bids received for similar projects. Water Quality Control Plant Superintendent Schumacker indicated that there are 42 facilities in the Bay Area and due to the current economy; contractors are very selective of project bidding. He is unaware of any similar projects currently out to bid and stated that staff contacted as many contractors available for the project with no response. The bid received is from the general contractor that is currently doing work at the plant. Councilmember Nicolas inquired about the aging facility (15 years) and if measures to control costs SPECIAL CITY COUNCIL MEETING APRIL 10, 2019 MINUTES PAGE 2 were in place. Superintendent Schumacker stated that the repair was planned and budgeted for accordingly. Councilmember Addiego inquired about receipt of the sole bid and asked if other agencies have also struggled with the lack of bids. He confirmed that 64 million gallons could be pushed through the p� mp daily and asked if there were concrete ponds. Superintendent Schumacker stated concrete ponds existed but the decision was based on putting the additional weight in water rather than concrete. He explained the weight and additional cost of concrete. Superintendent Schumacker explained the process of pumping and storing at the storage pond during storms. Councilmember Addiego inquired about the condition of the existing outfall line. Superintendent Schumacker stated it was recently inspected and in good condition. He stated a request for proposals would be issued in two years for additional inspection. Mayor Matsumoto indicated she could support the sole source since the company was currently onsite and doing work. Motion— Vice Mayor Garbarino/Second—Councilmember Nagales: to approve Resolution No. 44- 2019.Unanimously approved by roll call vote. 2. Report regarding Resolution No. 45-2019 awarding a construction contract to Seton Pacific Construction of San Francisco, California for the Antoinette Lane Underground Utility District Project, Phase 1 in an amount not to exceed $2,019,667, authorizing a total construction budget of $2,221,634 and approving Budget Amendment Number 19.049. (Jason Hallare, Associate Engineer and Kathleen Phalen, Swinerton) Kathleen Phalen, Swinerton, presented the report and indicated the contract was for construction of the first phase on Antoinette Lane. She discussed formation of the district and explained that the private development at 988 El Camino had to be constructed prior to completion of this project, therefore the project was phased. The project would clear the utilities to allow the Civic Center project to start. She stated the ordinance specified that the City was responsible for completing the design and construction of this project, with the utilities reimbursing the City for the cost of construction. The City received four responsive bids, with Seton Pacific the lowest bidder. Staff recommends a 10% contingency. She stated all utilities had reviewed the plans and had signed off on their cost share. The budget amendment would transfer Rule 20A funds replacing Measure W funds. Vice Mayor Garbarino asked the start date. Ms. Phalen stated the contract included 80 working days, with lead time, and anticipated the contractor would be working June—August, with clean up in September. She explained the process for connecting utilities. Vice Mayor Garbarino asked if there were anticipated issues around traffic due to construction. Ms. Phalen discussed the requirement for a traffic control plan. Vice Mayor Garbarino stated he wants to ensure minimal disruption to residents. He requested a copy of the Summerhill traffic control plan. City Manager Futrell stated he would provide the plan to Council. Councilmember Addiego expressed enthusiasm that four bids came in below the Engineer's estimate. He asked the total project cost. Ms. Phalen stated the total project was approximately $3 million. She explained the Rule 20 credits,which applied only to the PG&E share of approximately $1 million. SPECIAL CITY COUNCIL MEETING APRIL 10,2019 MINUTES PAGE 3 Mayor Matsumoto discussed SamTrans' bids and the need to rebid projects due to lack of response. Motion— Councilmember Addiego/Second—Councilmember Nicolas: to approve Resolution No. 45- 2019. Unanimously approved by roll call vote. 3. Report regarding a motion to accept the construction improvements of the Avalon -Brentwood Park Neighborhood Traffic Calming Project as complete in accordance with plans and specifications (Total Construction Cost $214,122). (Matthew Ruble, Acting Principal Engineer and Peter Vorametsanti, Swinerton) Peter Vorametsanti, Swinerton, presented the report of speed cushions. He presented images of Alta Vista before and after the project. The work included installation of 20 speed cushions and associated pavement markings and advanced warning signage which were inspected and found to be completed. Therefore, staff recommended the Council accept the project. Vice Mayor Garbarino asked if the restriping was completed. He stated the signage was confusing. Director Kim stated the striping was complete and staff would look into moving the speed limit signs. Councilmember Nicolas asked if the speed bumps were effective. Mr. Vorametsanti discussed the plan to conduct an after survey once the traffic had stabilized. He indicated staff would assess effectiveness in a couple of months. Councilmember Nagales asked if the impact to surrounding streets would be reviewed. Director Kim explained that speed humps reduced volumes and speeds. Vice Mayor Garbarino discussed the impact of hitting the speed pillows at 45 mph versus 25 mph. He stated the project had been very effective and the residents were pleased with the project. Councilmember Addiego stated it was good to hear neighborhood satisfaction and inquired about pavement markings. Director Kim stated the markings were put in after the fact based on residents' requests. Mayor Matsumoto discussed the pilot program and asked if the same process would be used for the next neighborhood, what the next neighborhood would be and how it would be determined. Director Kim explained that, based upon resident feedback and complaints, staff was reviewing Sister Cities, Hillside, and Randolph. Mayor Matsumoto recommended the use of roundabouts. Motion — Vice Mayor Garbarino/Second — Councilmember Nicolas: To accept the construction improvements of the Avalon -Brentwood Park Neighborhood Traffic Calming Project as complete in accordance with plans and specifications.
