Surface Water Fund — Stormwater Outfalls Water Quality Retrofit Program
Project No. 91241202
Contract 22-134, Amendment No. 3
ISSUE
Request approval for Amendment No 3. to Contract 22-134 in the amount of $98,268.
BACKGROUND
The goal of the Stormwater Outfall Water Quality Retrofit program is to improve the water quality of
stormwater discharges to the Green-Duwamish River from city roads. This project will retrofit four city
street discharge points out of eight that were prioritized by City staff. In a prior contract, Psomas
analyzed and ranked these eight discharge points based on seven criteria and also developed designs
for these four priority sites to 90% Plans. The first two sites were constructed in the fall of 2024 and
summer of 2025, one on Interurban Avenue S and the other on Tukwila International Blvd. The first
contract amendment was a time extension only, and the second amendment added final design and
construction management funding for the next two sites to be built in 2026, one on East Marginal Way
and the other on Fort Dent Way.
DISCUSSION
Amendment No. 3 includes additional funding for construction management services ($56,268) for the
first two sites and funding for utility potholing ($42,000) for next two sites.
FINANCIAL IMPACT
This amendment totals $98,268, 85% is reimbursable through two Department of Ecology (DOE)
Stormwater Financial Assistance Program grants. The first DOE grant (WQC-2023-Tukwil-00073) will
fund the construction management services ($56,268), and the second DOE grant (WQC-2025-Tukwil-
00039) will fund the utility potholing ($42,000) for the second two sites. Budgeted CIP Surface Water
revenue in the amount of $63,171.15 will cover the required 15% match for both grants.

Stormwater Outfall Water Quality Retrofit Project
Construction Services Supplement
Psomas Project Number: 9TUK010300
June 19, 2025
Psomas is providing construction management services for the construction contract to complete the City
of Tukwila Stormwater Outfall Water Quality Retrofit Project. The City of Tukwila has been selected to
receive funding through DOE Agreement No. WQC-2023-Tukwil-00073 ("Grant Agreement") in the State
Fiscal Year 2023 (SFY23) Funding Cycle. The work includes:
Site 1: Tukwila International Blvd at SR 599 Off -Ramp
Install two new modular wetland units, storm conveyance pipe, and restoration of gore area to treat
stormwater runoff before it outfalls to Riverton Creek.
Site 2: Interurban Ave S at 58th Ave S
Install new modular wetland unit, storm conveyance pipe, and street trench restoration to treat
stormwater runoff before it outfalls to the Duwamish River. This location will also be replacing
existing signalized intersection loops with permanent video detection.
A detailed scope follows:
I. INTRODUCTION
Shortly before construction began for the project it was discovered there were additional requirements for
completing the work at the SR 599 Off -Ramp due to the work being in WSDOT Limited Access Right -of -
Way. The Contractor intended to start work at this site, but had to shift work to the Interurban site until the
requirements of WSDOT were met. This caused a delay in the project starting and forced the project into
splitting the work into two construction seasons. A complete list of items that extended the project scope
and time to completion are as follows:
• Unexpected WSDOT coordination caused scope and time increases
o Structures installed within the WSDOT ROW had to be stamped by the Materials Lab,
requiring additional coordination time.
o The 35 working days were split between Fall 2024 and Spring 2025 creating additional
time administrative items required by the Contract.
o WSDOT coordination continued through the winter months to resolve their requirements
for the WQ vault yet to be installed within their limited access right-of-way.
o Certified payroll tracking continued through the suspension period.

EXHIBIT A-5
• The Contractor's vault supplier had delays in shipping the items to site. This forced the Contractor
to pave on two days instead of one for the Interurban site. Increasing the amount of testing required.
• New crushed rock and HMA materials were submitted for the work to be completed in the spring,
which required additional conformance testing.
• An unmarked conduit was discovered running through a section of the project. There were four
non -working days associated with this discovery as the Contractor lost efficiency and was working
on non -critical items during this time.
• Additional non -working days were granted for weather. Some work continued on these days but
was inefficient.
General Assumptions:
• There are 15 working days remaining in the Contract. Work is expected to wrap up within this
time, except for punchlist items.
• Coordination with WSDOT will continue as work progresses within their ROW.
• The proposed project team will include a part time Resident Engineer (10 hours a week), one full
time Construction Inspector, a part time Documentation Specialist (20 hours a week), and one part
time Project Engineer from Psomas's design team to review submittals and interpret Contractor
inquiries, as needed. The team also includes a sub -consultant to provide services for materials
testing and construction site observation to satisfy Tukwila Municipal Codes for work within
certain soil classifications.
• Consultant will coordinate during audits or traffic control operations related to project impacts and
help the City to complete any other required correspondence with outside agencies.
• Psomas design engineers will be available during construction to answer questions and review
RAM's, shop drawings, and answer RFI's.
• Consultant services will be performed in accordance with the WSDOT Construction Manual,
Contract plans & special provisions, and City of Tukwila engineering standards.
• The franchise Utilities will provide field inspection for all work surrounding the construction or
relocation of their utility systems if necessary.
• Coordination of construction with franchise utilities, if any, will be done by City Contractor.
Consultant will help facilitate coordination between utilities and Contractor as needed or requested
by City.

v. Interpret Contract Documents in coordination with the City, Contractor, and Psomas.
vi. Resolve questions which may arise as to the quality and acceptability of material furnished,
work performed, and rate of progress of work performed by the construction contractor.
vii. Support the Contractor's communication and responsibilities to answer questions from
property owners and the general public as needed.

"normal" work week may occur at night. Psomas does not differentiate day shift from night shift.
However, if the City's Contractor works a double shift (both day and night) within a single 24-hour
period this will constitute two working days. Consultant's hours for inspection are based on one
shift for number of working days allowed per Contract.
• The Consultant's monitoring of the construction contractor's activities is to ascertain whether they
