ISSUE
The Board of Directors (Board) must award the contract or reject bids within 50 days of the bid opening.
Authorization is also required for the General Manager to execute the Contract Documents subject to
submittal requirements.
BACKGROUND
The Pleasant Hill Sewer Renovations, Phase 2, District Project 5991 (Project) is part of the ongoing
sewer renovation within the Capital Improvement Budget (CI B) and Collection System Program aimed to
replace or rehabilitate deteriorated sewer infrastructure that is at the end of its useful life and in poor
condition. The Project has been coordinated with other improvements being completed by the Contra
Costa Water District and the City of Pleasant Hill's paving plans, as well as other utilities, businesses,
private property owners, and tenants.
This Project will replace or rehabilitate approximately 8,700 feet of small diameter sewers, maintenance
access structures, and other related sewer work within public rights -of -way and private easements. Central
San staff prepared the plans and specifications for the Project. Construction methods primarily include
open trench, horizontal directional drilling, pilot tube guided boring, and cured -in -place pipe rehabilitation.
An overview map of all site locations is shown in Attachment 1.

The Engineer's estimate for construction is $4,700,000. This Project was advertised on April 10 and April
17, 2023. Five sealed bids ranging from $5,888,730 to $6,788,000 were received and publicly opened on
April 27, 2023. The Capital Projects Division conducted a technical and commercial review of the bids and
determined that Devaney Engineering, Inc. is the lowest responsive and responsible bidder with a total bid
amount of $5,888,730. A summary of bids received is shown in Attachment 2.
Central San will administer the construction contract and provide construction management, resident
engineering, survey, administration, and submittal review. Consultant inspection will be performed by one
of Central San's consultant inspection service contracts.
CEQA
Staff has concluded that this Project is exempt from CEQA under Central San CEQA Guidelines Section
15302 because it involves replacement of existing facilities at substantially the same locations and with the
same purpose and level of activity as the facilities being replaced. Any capacity increases are for non -
growth inducing, wet weather purposes. The Project also is exempt under Central San CEQA Guidelines
Section 15061(b)(3), since it can be seen with certainty that there is no possibility that the activity in
question may have a significant effect on the environment. This certainty is based on Central San's
experience with numerous sewer construction projects of this nature, the relatively short distance involved,
and Central San's mitigating construction specifications. These specifications are standardized general
and special conditions that are made part of the Project bid documents to address environmental
considerations, such as protecting trees and riparian areas, as well as compliance with applicable federal,
state, county, district, municipal and local laws, ordinances, orders, and regulations. Approval of this
Project will establish the Board's independent finding that this Project is exempt from CEQA.
ALTERNATIVES/CONSIDERATIONS
Central San staff has coordinated the Project with the City of Pleasant Hill, Contra Costa Water District,
private property owners, businesses, nearby residents, and utilities. Delaying or postponing the sewer work
is not recommended. The public sewers are in need of replacement and due to the City's paving plans,
the proposed timeline is recommended by staff.
The planning effort for this Project has been in the Cl B for several years and has been difficult to
coordinate due to the below industry standards for the existing utilities and paving in the neighborhood.
Performing this work along with the other agencies is cost effective for all parties and reduces public
impacts to the residents.
FINANCIAL IMPACTS
The total estimated project cost is $7,958,000 which includes planning, design, bid price, additive bid
items, contingency, construction management, and consultant costs as detailed in Attachment 3.
This Project is included on page 203 of Central San's Fiscal Year 2022-2023 Budget, and the
construction will be funded by the Collection System Sewer Renovation, Phase 2 on page 225. There is
adequate funding for the Project.
Staff is recommending a 10 percent contingency on this Project since additional work may be added to
urgently repair or replace nearby sewers and to cover any expenses due to unknown conditions and
changes associated with renovation work.

COMMUNITY OUTREACH
Central San staff did extensive homeowner outreach to prepare residents for the upcoming construction
work. Initial project letters were sent in the Fall of 2022 informing residents of the design work. Throughout
the course of design, staff addressed email and phone inquiries regarding the Project and conducted in -
person outreach with several easement homeowners. The public was also invited to a public workshop that
was held at the Pleasant Hill Senior Center on April 5, 2023 to address any questions or concerns
regarding the Project.
Additionally, the public was encouraged to reach out with any additional questions or concerns they may
have. To date, all questions and concerns received have been answered and addressed.

The Engineering and Operations Committee reviewed this matter at its meeting on May 8, 2023, and
recommended

Engineer's Estimate
versus Bids
More than half of the price difference is related to
open -trench installation (Costs shown below are $
per feet):
The past 3 years, open -trench prices average
$375 and some bidders provided pricing of
$277.
This project has deeper excavations and added
complexity compared to previous projects.
Engineer's estimate is $400.
Devaney Engineering, Ines bid is $540 and
average of all bidders is $580.
35% increase from Engineer's estimate is also
due to higher costs of materials and labor, and
inflation over the past few years.
