STAFF RECOMMENDATION:
Adopt the Resolution Approving the Plans and Specifications and Awarding a Contract to
Suulutaaq, Inc. for the Green Stormwater Infrastructure Project, CIP Nos. ST0121 and ST0517.
FINANCIAL IMPACT:
The bid submitted by Suulutaaq, Inc. is $2,501,546. Staff recommends a construction contingency
of $250,000 (about 10%) to facilitate change orders for unforeseen construction issues, bringing
the total potential construction cost to $2,751,546. Sufficient funds are available in the approved
budgets for CIP Nos. ST0121 and ST0517.
The bid includes two major components, Base Bid #1 Storm Drain and Bioretention Area, and
Base Bid #2 Amador Valley Boulevard Improvements. Costs for Base Bid #1 are covered by CIP
No. ST0121 Green Stormwater Infrastructure, which includes funding from a General Fund
Designation as well as a reimbursement from Alameda County Transportation Commission
(ACTC) in accordance with a cooperative agreement approved by the City Council on April 16,
2024 (Resolution 27-24). Per the agreement, ACTC will reimburse the City for 75% of the Base Bid

DESCRIPTION:
The 2022-2027 Capital Improvement Program (CIP) includes Green Stormwater Infrastructure,
CIP No. ST0121, and Citywide Bicycle and Pedestrian Improvements, CIP No. ST0517.
Green Stormwater Infrastructure, CIP No. ST0121, provides for planning, design, and construction
of various citywide projects that will improve water quality and provide other environmental
benefits in accordance with the Green Stormwater Infrastructure Plan, which was approved by the
City Council on June 18, 2019. One of the projects included in this CIP is the Green Stormwater
Infrastructure - Iron Horse Trail, South of Amador Valley Boulevard project (GSI Project) to treat
stormwater runoff from the adjacent neighborhoods prior to discharge into South San Ramon
Creek and Alamo Creek. The GSI Project is being done in cooperation with Alameda County
Transportation Commission (ACTC).
ACTC is the lead agency implementing their SR84 Expressway Widening and SR84/I-680
Interchange Improvements project, including the improvements to meet stormwater treatment
and flow control requirements specified by the San Francisco Bay Regional Water Quality Control
Board (RWQCB). Caltrans and the RWQCB have approved off -site stormwater flow control for the
ACTC project. The City's GSI Project has been modified to accommodate the requirements of the
ACTC project by incorporating changes to increase the tributary area of impervious surface and
incorporate flow control. In exchange for accommodating the ACTC project requirements, the
additional project costs will be reimbursed by ACTC.
On February 7, 2023, the City Council approved a cooperative agreement with ACTC (Agreement
No. A23-0012) for the preliminary engineering, environmental clearance and permitting, and final
design. The agreement assigned responsibilities for each agency, including ACTC's responsibility
to fund 75% of the costs associated with the first phase of the project.
On April 16, 2024, the City Council approved a cooperative agreement with ACTC (Agreement No.
A24-0014) for the construction phase of the combined project, which includes construction
capital, construction management, and inspection. The agreement assigned responsibilities for
each agency, including ACTC's responsibility to fund 75% of the costs for the construction phase of
the project, which was estimated at $2,800,000. Staff will return to the City Council with
subsequent agreements for the long-term operation and maintenance.

Citywide Bicycle and Pedestrian Improvements, CIP No. ST0517, provides for planning, design,
and construction of various pedestrian and bicycle facilities throughout the City, including
sidewalks and improvements related to the Americans with Disabilities Act (ADA). On June 4,
2024, the City Council approved a request to the Metropolitan Transportation Commission for the
Allocation of Fiscal Year 2024-25 Transportation Development Act Article 3 (TDA)
Pedestrian/Bicycle Project Funding for two projects, one of which is the pedestrian improvements
along Amador Valley Boulevard that will be constructed with this project. Additional funding for
the pedestrian improvements is provided by various transportation funds allocated in the
approved CIP No. ST0517.
The GSI Project will install a bioretention basin for stormwater treatment and hydromodification
management, including storm drainpipes, inlets, landscaping in the basin, asphalt concrete trail,
seating, and interpretive signage. The GSI Project will also remove the existing sidewalk and
construct a wider sidewalk along Amador Valley Boulevard, from the Iron Horse Regional Trail
intersection to Stagecoach Road, and will improve curb ramps and the median refuge at the trail
crossing.
Bid Process and Results
The City of Dublin issued a bid package for the GSI Project on April 24, 2024. The bid package
consisted of two required components, Base Bid #1 Storm Drain and Bioretention Area, and Base
Bid #2 Amador Valley Boulevard Improvements. The required components together total 54 base
bid items. An Additive Alternate component, consisting of two additive bid items, was also
included in the bid package. The two additive -alternate items were for installation of empty
conduit and pull boxes along Amador Valley Boulevard for potential future fiber optic
communications for City use.
Two sealed bids were received on May 30, 2024, with the base bids ranging from $2,501,546.00 to
$2,792,997.60, and additive alternate bids ranging from $210,236.00 to $242,104.00. The lowest
base bid, which is the total of Base Bid #1 Storm Drain and Bioretention Area and Base Bid #2
Amador Valley Boulevard Improvements, of $2,501,546.00 was submitted by Suulutaaq, Inc. A
summary of the bids is provided as Attachment 4.
Staff reviewed the bid results, checked references and necessary licenses, and recommends that
the City Council award the construction contract to Suulutaaq, Inc. as the lowest responsive and
responsible bidder. Staff is not recommending awarding the additive -alternate bid items because
the low bid exceeds the engineer's estimate by approximately 13%, there are no near -term plan to
install fiber optic lines in this location, and there is no funding currently approved or allocated in
the City's operating or capital improvement plan budget for this work.
To facilitate the approval of contract change orders and avoid construction delays, it is requested
that the City Manager be authorized to approve change orders up to the contingency amount of
$250,000. The resolution will authorize this change as it relates to the project. If the construction
contract is awarded to Suulutaaq, Inc., Staff expects work to begin in late July 2024 and complete
in late 2024.

Community Workforce Agreement
On January 11, 2022, the City Council approved a Community Workforce Agreement (CWA) with
the Building and Construction Trades Council of Alameda County and its Affiliated Local Unions.
The CWA is applicable to public works projects valued at over $1,000,000, ensures that there are
no labor issues related to said projects, and bolsters local efforts to connect residents with careers
in the building and construction trades. The CWA includes a Local Hire Goal where 20% of all
hours on a project are worked by Local Residents, which are defined as individuals that reside
within Alameda County or within a 15-mile radius of City limits. The CWA also requires
contractors to hire one new apprentice for the first $1,000,000 of construction costs, and an
additional new apprentice for every $5,000,000 construction costs, based on the engineer's
estimate. Apprentices must work a minimum of 10% of the total craft's work hours, but the CWA
allows that apprentices may be deployed to another project to ensure the minimum number of
hours are met.
Staff worked with a consultant, Workforce Integrity and Training Solutions, to prepare bid
documents and solicit bids for the GSI Project that comply with the provisions of the CWA. The
provisions include the requirement that responsive bidders include an executed Agreement to be
Bound to and by the CWA, and that all subcontractors of the successful bidder also execute the
Agreement to be Bound within 14 days after Notice of Award.

PROJECT DESCRIPTION
This project provides for the planning, design, and construction of various citywide projects that will improve water quality and provide other environmental benefits
in accordance with the Green Stormwater Infrastructure (GSI) Plan, which was approved by the City Council on June 18, 2019. The GSI Plan and associated
implementing projects, as well as trash load reduction requirements, are mandated by the Municipal Regional Stormwater Permit (MRP). Projects include: stormwater
full trash capture device installation throughout the City, and construction of GSI along the Iron Horse Trail corridor, south of Amador Valley Boulevard. GSI
planning and planning for the installation of trash capture devices began in FY2021-22. The installation of the trash capture devices is anticipated in FY2023-24.
Construction of GSI along the Iron Horse Trail corridor, south of Amador Valley Boulevard, is anticipated in 2024.
This project is funded by a General Fund Reserve set aside for this purpose. The City and Alameda CTC entered into a Cooperative Agreement on February 7, 2023
to partner on the design and environmental permitting phase for a bio-retention and hydromodification management facility along the Iron Horse Trail corridor,
south of Amador Valley Boulevard, that satisfies a portion of the City's GSI requirement and Alameda CTC's project, SR84 Expressway Widening and SR84/I-680
Interchange Improvements. Alameda CTC's share of the costs is 75% of the total, which will be reimbursed to the City after expenditure. Both agencies will enter
into a subsequent agreement for the construction phase.
The "Other" funding is from Alameda County Transportation Commission.
ANNUAL OPERATING IMPACT: To be determined. On -going operations and maintenance (O&M) expenditures for installed facilities are required, but may be
equal to current maintenance expenditures, particularly for retrofit and replacement projects. For completely new projects, O&M costs are estimated at 1.3% of
construction cost for parcel based GSI or regional stormwater controls, and 3.6% of construction costs for green street projects. Alameda CTC will enter into a long-
term maintenance agreement with the City for the GSI along the Iron Horse Trail corridor, south of Amador Valley Boulevard, to account for the on -going
maintenance costs of the portion of the facility that satisfies their project.
