Amendment No. 6 to CAG-17-050
City of Renton
Lift Station and Force Main Rehabilitation Group 1 Facilities
Preliminary (Group 2) and Final (Group 1B and Group 2) Design for
Rehabilitation Improvements and Services During Bidding
August 2021
Background
In 2017, the City of Renton (City) retained RH2 Engineering, Inc., (RH2) for the predesign, design, and
services during bidding and construction for improvements to 17 wastewater lift stations (LS) and
associated force mains to be completed in multiple phases over several years. The project started
with the City breaking down these facilities into Phase 1 and Phase 2 based on rehabilitation priority.
However, a few of the Phase 1 LS projects required property acquisition and other permitting
requirements. In an effort to prevent delaying the improvements to the remaining lift stations, the
City decided to divide the Phase 1 lift stations into Groups 1A and 1B. It is anticipated that the Phase
2 lift stations will be divided into different groups as well. The following provides a detailed
breakdown of the lift stations by phases and groups:
PHASE 1 (COMPLETED)
Group 1A
Valley. The rehabilitation improvements for these facilities have been designed, bid, and
constructed as part of Amendments Nos. 2 and 4.
PHASE 2
Group 1B: Cottonwood, Devil
preliminary 60-percent design has been completed for these four lift stations. Continuing
property acquisition efforts likely will result in addressing further design for the Cottonwood
Lift Station separately from the other three Group 1B facilities. Completion of the final design
and advertisement for bidding is slated to occur by the end of 2021.
o Group 1C: At the time this Scope of Work was prepared, the required easement for
the Cottonwood LS was still being negotiated to accommodate the proposed electrical
building and generator. The timeline of when the City will be able to obtain an
easement from the property owner is uncertain. Therefore, this lift station will be
improved later, under a separate group number, as part of Phase 4.

PHASE 3
Group 2: Liberty, Wedgewood, Lake Washington Beach, Lake Washington No. 2, Lake
Washington Flushing Station, Talbot Crest, Long, Westview, and Kensington Crest. These lift
stations have been assessed initially for anticipated improvements in coordination with City
staff. RH2 will start with conceptual design to 30-percent design and evaluate anticipated
construction costs, as well as progressing to preliminary 60-percent design for all 9 of these
facilities. Due to Kensington Crest likely requiring acquisition of an easement, it will be
deferred to Group 2B at the 60-percent milestone, along with any other facility that is
determined to require an easement.
o Group 2A: Liberty, Wedgewood, Lake Washington Beach, Lake Washington No. 2,
Lake Washington Flushing Station, Talbot Crest, Long, and Westview. Plans for
rehabilitation of these lift stations will be developed from the 60-percent preliminary
design level to 90-percent final design, and finally proceed to bidding and
construction.
o Group 2B: This amendment will determine the easement requirements for the
Kensington Crest improvements for the City to begin the acquisition process. The
timeline for securing an easement is unknown; therefore, this lift station and any
other Group 2A facilities that necessitate easement acquisition will be improved
under a separate group number and as part of Phase 4.
PHASE 4
Group 1C: Once easement negotiations are finalized for the Cottonwood LS, improvement
plans will be developed from 60-percent to 90-percent design, and subsequently proceed to
bidding and construction.
Group 2B: Once easement negotiations are finalized for the Kensington Crest LS and any
other facilities that need easements, improvement plans will be developed from 60-percent
to 90-percent design, and subsequently proceed to bidding and construction.
Currently, RH2 is under contract to complete the design for the Group 1B and 1C lift stations: Baxter,
Cottonwood, the remaining portion of East Valley. RH2 also is under contract to
provide one (1) round of services during bidding (SDB). As part of Phase 2, RH2 will complete the
design for improvements to the three Group 1B facilities, to be advertised for bidding by the end of
2021.
Phase 4 will be completed on an independent schedule and design track, depending upon time
needed to resolve any property acquisition and permitting needs.
Table 1 identifies the Groups 1B, 1C, 2A, and 2B projects included in this amendment and the
anticipated types of improvements involved.

Update the Groups 1B and 1C
to reflect current labor and material prices, as well as any revisions in approach to the four
(4) Groups 1B and 1C projects.
Assumptions:
It is assumed that the initial scope of improvements for Groups 1B and 1C have not changed.
This Task is meant to ensure a smooth design process as Groups 1B and 1C progress to final
design.
RH2 Deliverables:

assumed that Kensington Crest LS will be deferred to Phase 4 (Group 2B)along with the Cottonwood
LS (Group 1C).
This Task will determine whether any of the remaining eight (8)Group 2 projects, now classified as
Group 2A facilities, should be combined with Kensington Crest and deferred to Phase 4. Otherwise,
they will be part of Phase 3 (Group 2A)to be designed and advertised for bid sometime during2022.
Refer to Table 1 in the Background for anticipated project phasing.
Property acquisition for the Cottonwood LS and FM project likely will require a later completion of
final design for that facility, postponing this work into a separate Group 1C set of projects, as
described in the Background portion of this Scope of Work.
Due to the expected property and easement acquisition for the Kensington Crest site and the
unknown schedule that will be incurred, it is anticipated this facility will be included in Group 2B and
scheduled to be bid later in a separate Phase 4 set of projects that can be completed concurrently
with Group 1C.
Upon finalization of this site and group organization, the remainder of the design work will progress
in the following phases.
Phase 3 includes tasks associated with advancing the Group 2A facilities from their current design
level to bid-ready design, as well as providing SDB.
Phase 4 includes tasks associated with advancing the Groups 1C and 2B facilities from their current
design level to bid-ready design, as well as providing SDB.
Approach:
Discuss with City staff which Group 2 projects can advance to preliminary and final design
(Group 2A) and which can be addressed later (Group 2B) with Group 1C facilities.
Assumptions:
Geotechnical investigations are anticipated for the Group 2 lift station and force main
improvements, but this assumption will be validated during Phase 3 or 4 design work.
Provided by City:
Attendance at one (1) meeting to discuss project phasing.
RH2 Deliverables:

at 30-percent design and ready for updating to the60-percent design milestone. The tasks that follow

Task 27 Geologic Exploration and Surveying (Groups 2A and 2B)
Objective: Perform engineering geology site investigations and reporting as needed for final design
of the Group 2 facilities that warrant this effort, as well as property boundary surveying.
Approach:
Perform a limited geological investigation to observe, characterize, and document earth and
groundwater conditions of the sites. Identify potential geologic hazards and alternatives to
mitigate the identified geologic risks and evaluate potential constructability issues for the EG
foundationsand associated retaining walls. RH2 will coordinate with City staff to perform test
pits for geologic investigation as warranted.
Prepare an engineering geologic report for the two (2) sites that follow, which will include a
summary of geological and groundwater conditions and provide recommendations to design
and mitigate construction geologic hazards, the EGfoundation,and associated retaining wall.
The engineering geology report will include a figure showing exploration locations,
photographs, and logs from each test pit performed.

It is assumed that surveying will be performed by a professional land surveyor (PLS) retained
by RH2 to provide horizontal and vertical survey control and topographical information,
including surface features, underground utilities, roadway and utility alignments,
rights-of-way, and property lines.
