CBD Sewer Repair Phase 413
Lining and Open Trench Repair Design and Construction Management
January 2023
Background
The City of Tukwila (City) has programmed yearly upgrades to the wastewater collection system in
its Central Business District (CBD). The sanitary sewer pipe in the CBD, has been especially prone to
failure because of its 50- to 60 -year age, material (asbestos cement), and submergence below the
groundwater table. The City conducted four major cured -in-place pipe (CIPP) projects in 2014, 2016,
2018, and 2021 to repair aging sewer pipe. Design of the Phase 413 project began in December 2021.
A review of the pipes originally scoped for CIPP lining found additional pipes needing lining. The
following additions to the original scope of work have been made:
1. CIPP lining of approximately 1,198 linear feet (If) of sewer main along S 180th Street
(Exhibit D).
2. CIPP lining of approximately 4,269 If of sewer main south of the Green River (Exhibit D).
3. Open -cut replacement of approximately 40 If of sewer main on 58th Avenue South (Exhibit E).
Deliverables will be provided in electronic VIS Word, PDF, and GIS formats as appropriate and
requested by the City.
It is assumed that all meetings will be attended via videoconference, unless otherwise noted.
Task 1— Prepare Plans, Specifications, and Bid Documents for CBD Sewer
Rehabilitation Phase 4B — CIPP Lining (Amending Fee Only)
Objective: Amending fee for the original task to include an additional 5,467 If of sewer main.
Approach: No change from original task.
Assumptions:

originally scoped in Task 1. A separate set of plans, specifications, bid documents, or estimate
will not be prepared for this additional sewer pipe.
Participation or Information Needed from City:
0 No change from original task.
RH2 Deliverables:
0 No change from original task.

Scope of Work
City of Tukwila
CBD Lining Project Phase 4B — Lining and Open Trench Repair
October 2021
Background
The City of Tukwila (City) has programmed yearly upgrades to the wastewater collection system in
its Central Business District (CBD). The sanitary sewer pipe in the CBD has been especially prone to
failure because of its 50- to 60 -year age, material (asbestos cement), and submergence below the
groundwater table. The City has conducted four major cured -in-place pipe (CIPP) projects in 2014,
2016, 2018, and 2021. For this Scope of Work, RH2 will design the fifth round of pipeline
improvements to be performed in 2022, which includes approximately 2,360 linear feet (If) of sewer
main in the areas identified in the table that follows for the CBD Sewer Rehabilitation Phase 4B —
CIPP Lining project as outlined in Tasks 1, 4, and 5.

Additionally, one sewer main along Andover Park West was not lined during the most recent CIPP
project due to a noticeable sag in the sewer main identified during construction. For this Scope of
Work, RH2 will design the replacement and/or repair of approximately 430 If of sewer main along
Andover Park West nearTukwila Pond Parkforthe CBD Sewer Rehabilitation Phase 413—Open Trench
Repair project as outlined in Tasks 2 through 5. If additional utility design is needed for this sewer
repair, Task 7 will be utilized.
Additionally, the City awarded a contract to Michels Construction using the design -bid -build process
to construct the CBD Sewer Rehabilitation Phase 4A— CIPP Lining project. Construction started in the
summer of 2021. RH2 was selected to perform the construction observation and administration for
the CBD Sewer Rehabilitation Phase 4A — CIPP Lining project under the direction of the City's Project
Manager (PM). For this Scope of Work, RH2 will provide on-site construction observation and
construction administration to the City for the CBD Sewer Rehabilitation Phase 4A — CIPP Lining
project as outlined in Task 6.
Deliverables will be provided in electronic MS Word, PDF, and GIS formats as appropriate and
requested by the City.
It is assumed that all meetings will be attended via videoconference, unless otherwise noted.

CBD Lining Project Phase 413 - Lining and Open Trench Repair Scope of Work
Task 1— Prepare Plans, Specifications, and Bid Documents for CBD Sewer
Rehabilitation Phase 4B — CIPP Lining

50 feet plan scale, based on City -identified sewer pipelines that need CIPP lining. Plans will note
pipe runs to be lined and will use GIS files provided by the City as the base map. It is assumed
that the selected contractor will submit traffic control and temporary wastewater bypass plans
for approval during the construction phase. Specify flow rates to be bypassed based on
information from the City. Estimate the quantity of required bid items to construct the project
and write payment descriptions for each item. Prepare a preliminary Engineer's Estimate of

Engineer's Estimate, for City review.
1.3 Prepare 95 -percent review sets of plans, technical specifications, bid documents, and Engineer's
Estimate of probable construction cost based on City review comments. The CIPP lining will be
split into two (2) parts: 1) base bid; and 2) bid alternate. The bid alternate is to include work to
be performed if the total bid prices for both the base bid and bid alternate are within the City's
budget. A schedule of pipe size, length, and material will be prepared for the pipes identified in
the base bid and bid alternate. Assemble PDFs of technical specifications, plans, bid documents,
and Engineer's Estimate of probable construction cost for the CIPP lining. Technical
specifications are to be based on the Washington State Department of Transportation/American
Public Works Association (WSDOT/APWA) format. Technical specifications are to be based on

construction cost based on City review comments.
1.5 Perform limited coordination with King County regarding the CIPP lining near the intersection
of Strander Boulevard and Andover Park West for the sewer mains that connect to King
County's sewer interceptor that is located along Strander Boulevard.

Task 7 — Management Reserve
RH2 has specified a contingency as part of the Fee Estimate to accommodate for changed conditions,
unforeseen complications, or additional utility design (such as water main or storm main
improvements) that may arise during the project. In this event, RH2 will notify the City's PM of the
time and expense warranted to address the new issue(s) that arise and will request to authorize use
of the contingency funds. RH2 will only attempt to address these issues with the City's prior
authorization. RH2's PM will contact the City PM via email to request access to these funds should
the need arise. Additional utility design could include the design of water main or storm main
improvements to accommodate the sewer main repair along Andover Park West.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2021 to 2026
PROJECT: CBD Sanitary Sewer Rehabilitation Project No. 91140203
DESCRIPTION: The asbestos concrete pipe in the CBD (commercial business district) is approximately 45 years old and
becoming soft. Slip lining the pipe will reinforce the strength with little impact to roadways and minimal excavation.
JUSTIFICATION: If the pipe collapses, the street will have to be excavated and the cost of the repairs will be significant. We have
had four major pipe failures on Andover Park West and Andover Park East.
STATUS: In 2014 and 2015, over 10,500 feet of asbestos sanitary sewer pipe were relined. In 2020 through 2024,
15,000 feet of asbestos sewer is scheduled to be relined.
MAINT. IMPACT: Reduced maintenance and repair costs.
COMMENT: A Public Works Trust Fund loan was successfully obtained in 2012 for $750k.
