ISSUE
On August 16, 2023, (#) 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
$200,000 and transfer funds over $500,000 within the Capital Improvements 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.
August 14, 2023 EOPS Regular Committee Meeting Agenda Packet - Page 52 of 64
Page 2 of 11
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 the Project map, Attachment No. 1.
Last November, 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 back 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 force main near the discharge structure,
including the failed pipe location, and determined based on the video and external inspection 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 the services of 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 a 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 the 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 replacement of the aerial crossing.
Due to the urgency of the situation, staff reached out to Carollo Engineers (Carollo) to advise and provide
engineering 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. Coordinating and obtaining permits with UPRR has been a long and difficult 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 make 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. 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. The Project is also offering incentives for the Contractor to complete any portion of the permanent
installation, especially the aerial crossings, to save time and costs for the temporary work and overall
project costs. An incentive of up to $200,000 is being proposed in the Contract.
Based on the Project complexity, Central San conducted a formal pre -qualification review of General
Contractors, receiving Statements of Pre -Qualifications from five (5) interested General Contractors. The
solicitation was publicly advertised on Planetbids 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.

Page 3 of 11
Upon review, all five General Contractors consisting of Cratus, Inc., J MB Construction, Inc., McGuire and
Hester, Mountain Cascade, Inc., and Steve P. Rados, Inc. were approved to participate in the bidding
process.
Staff and Carollo prepared the plans and specifications for the Project. This Project was again advertised
on August 2, 2023, with the final bid plans and complete list of specifications for the vendors and sub-
contractors. XXXX sealed bids ranging from $X,XXX,XXX to $X,XXX,XXX were received and publicly
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 XXXXX (XXXX) is the
lowest responsive and responsible bidder. A summary of bids received is shown in Attachment 2.
Capital Projects staff will provide oversight and construction management of the Project. Carollo will
provide technical support and engineering services, and inspection may be supplemented by one of
Central San's as -needed consultants. Operations staff will support the Project as required to coordinate
shutdowns and testing.
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 Improvements 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 by 70 percent. The proposed funding source is a program budget used for sewer renovation
projects that currently has adequate cashflow for the sewer renovation project planned and for the
force main work.
FINANCIAL IMPACTS
The total estimated project cost is $3,700,000 million which includes staff time, consultant costs,
construction contract, contingency, construction management, and other costs detailed in Attachment No.
3.
The Project was initiated under the General Manager's delegated authority for contingency projects at
$200,000. The remaining $3,500,000 million needed to fully fund the Project will be transferred from the
Collection System Sewer Renovation - Phase 2, which has adequate funds in Fiscal Year (FY) 2023-24 at
$18,500,000 million as detailed on page 231 of Central San's Budget.

Project Background
Martinez pumping stating has dual 20-inch,
approximately 1-mile long force mains, that
discharge into a gravity structure at the Refinery.
November of 2022, Staff was notified of a small leak
on one of the force mains on Union Pacific Railroad's
(UPRR) right-of-way. The force main was
immediately repaired with a carbon fiber wrap.
CCTV on both force mains as well as visual
inspections showed various stages of corrosion on
the aerial and exposed pipelines, especially
internally.
Staff hired Carollo Engineering (Carollo) to advise on
how to fix the force mains since they are currently
working as Construction Manager for the Martinez
pumping station projects.
Staff recommends to permanently replace the last
650 feet of both force mains within a year, of which a
portion is related to work with UPRR permits.
Work may include temporary repairs and pipelines
prior to the wet weather season.
