2. Early Works Design Phase Modifications
2.1 RWPS Driveway Stabilization (Overall Task 8E)
Following the 30% Design Workshop and site visit in June 2025, it was identified that the existing ecology
blocks lining the sides of the driveway have started to erode away. Following the workshop, Jacobs
completed an alternatives evaluation to look at short-term and long-term options to stabilize the driveway
and provide support to the security fence installation along the driveway. Results and a recommendation
were shared with the City at the 60% Design Workshop in September 2025, including driveway stabilization
using grade beams and walls along the edge of the driveway to replace the ecology blocks as a bid
alternative to the Early Works project. Ground penetrating radar (GPR) was completed in February 2026 to
verify the location and depths of the raw water pipes along the driveway.

This amendment includes detailed design of the driveway stabilization developing 90% and final (100%
complete) design documents consisting of technical specifications and drawings. It includes a 2-day site visit
for a civil engineer to verify site conditions for the final design.
City will provide review comments for each design milestone in a Bluebeam Revu Studio Session coordinated
by Consultant. City will internally adjudicate its review comments to provide clear direction for Consultant.
Consultant will provide a written response within the Bluebeam Revu Studio Session to each written review
comment provided by City and incorporate the comments into the subsequent design documents
accordingly.
Assumptions:
· Additional works included in this amendment will be bid as part of the Early Works Project
construction contract.
· Results of GPR utility locate will be used for driveway stabilization design and must be completed
prior to finalization the design of the driveway.
· Level of effort is based on the addition of two (2) drawings:
o Civil Site Plan
o Structural Details
2.2 RWPS HVAC Design (Overall Task 8F)
During the 60% Design Workshop in September 2025, the City noted that there are issues with control
panels overheating in the RWPS due to a lack of ventilation. Two larger pump motors will be designed as
part of the raw water pump replacement in Early Works base scope. These larger motors will generate more
heat and any existing ventilation issues within the RWPS can worsen. An evaluation of HVAC requirements
will be performed as part of Amendment 5. Following this evaluation, the City will decide on an alternative
to carry forward to detailed design.
Consultant will complete a detailed design of the selected HVAC system by developing 90% and final
(100% complete) design documents. The completed design documents will consist of technical
specifications and drawings.
City will provide review comments for each design milestone in a Bluebeam Revu Studio Session coordinated
by Consultant. City will internally adjudicate its review comments to provide clear direction for Consultant.
Consultant will provide a written response within the Bluebeam Revu Studio Session to each written review
comment provided by City and incorporate the comments into the subsequent design documents
accordingly.
Assumptions:
· Additional works included in this amendment will be bid as part of the Early Works Project

o Plan and Air Flow Schematics
o Sections and Details
2.3 Transformer and Levee Conduit Design (Overall Task 8G)
A National Energy Code (NEC) analysis completed by Jacobs suggests that the RWPS is currently
overloaded. During initial coordination with Franklin PUD on the RWPS improvements, PUD indicated that
they’re at capacity with existing transformers and a new pad-mounted transformer is required to provide the
increased power capacity to the RWPS. Further investigation by Jacobs and the City showed that the existing
conduits between the current transformer and RWPS are not large enough for additional lines to be added. A
new conduit will need to be routed between the new pad-mounted transformer by PUD to the RWPS. It is
assumed that the transformer pad and conduit construction will require USACE, rather than railroad (BNSF)
coordination. Coordination with Franklin PUD and USACE regarding the details of transformer placement
and permitting/easement requirements for electrical conduit through the existing levee, respectively, will
occur as part of Amendment 5.
Consultant will complete a detailed design of the project by developing 90% and final (100% complete)
design documents. The completed design documents will consist of a technical specification for the
transformer and associated drawings.
City will provide review comments for each design milestone in a Bluebeam Revu Studio Session coordinated
by Consultant. City will internally adjudicate its review comments to provide clear direction for Consultant.
Consultant will provide a written response within the Bluebeam Revu Studio Session to each written review
comment provided by City and incorporate the comments into the subsequent design documents
accordingly.
Assumptions:
· Additional works included in this amendment will be bid as part of the Early Works Project
construction contract.
· City will coordinate with Franklin PUD on transformer location.
· Construction area is within USACE property. No coordination with BNSF is required.
· Level of effort is based on the addition of two (2) electrical drawings:
o Electrical Site Plan
o Site Plan Details
2.4 Early Works Phase Final Design (100% Design) (Overall Task 8)
A Management Reserve was established as part of Amendment 2, intended to be used for Early Works Phase
final design (100% design). Amendment 6 includes approval for the use of these Management Reserve
funds for the Early Works 100% complete submittal. The use of the 100% design budget in management
reserve was contingent on receiving construction funding for the Early Works project. In January 2026, the
City approved the $14.7M Drinking Water State Revolving Fund (DWSRF) loan to fund the Early Works
construction.
Consultant will prepare a 100% complete submittal of the design, including front end specifications and an
Engineers Opinion of Probable Construction Cost (EOPCC). Consultant will incorporate City’s and agency
Butterfield WTP Improvements Scope of Work
7
review comments from the 90% submittal into the 100% complete design submittal. The 100% complete
submittal will be used to bid the construction contract. The Draft 100-percent complete design package
review comments will be discussed at a subsequent project manager check-in call, as needed. No meetings
to review or discuss the Final 100-percent complete design package are planned or budgeted. Design
changes that impact the cost estimate are not anticipated after 90% design, but the estimate will be
updated based on the 100% design if needed.
Consultant will submit electronically stamped 100-percent-complete contract documents submittal in
Unlocked PDF and CAD format for use by the City for bidding the construction contract. PDF drawings will be
half-size, 11”x17”. A total of 73 drawings will be included in the contract set as shown in the table below.

3. Pilot Study (Overall Task 15)
The Washington Department of Health (DOH) requires pilot testing to design new filters at loading rates
greater than 6 gallons per minute per square feet (gpm/sf). Filters designed with higher loadings rates
reduce overall footprint and construction costs, as more flow can be pushed through a filter. The pilot study
will include ozonation, rapid mix, coagulation/flocculation, and filtration treatment processes to mimic the
new process. The results of the pilot study will be used to establish ozone demand/decay for ozone system
design criteria, evaluate optimal coagulant dose for chemical building sizing, confirm a shortened
flocculation hydraulic residence time (HRT), and confirm an increased filter loading rate (FLR) to reduce
construction costs. The results will also inform chlorine demand post-treatment for on-site hypochlorite
generation sizing and confirm disinfection byproduct (DBP) formation potential.
The pilot study will be split into three tasks:
· Planning and procurement
· Operation
· Data analysis and reporting
3.1 Pilot Test Planning

Deliverables:
· Workshop presentation and minutes documenting treatment scheme decisions.
4.2 Revised Site Plan
The previous site plan developed for the new Butterfield WTP was based on new facilities and treatment
processes being constructed on the existing Butterfield WTP site. Consultant will develop three preliminary
site plans for a greenfield WTP constructed in the empty plot of land to the east of the existing solids drying
beds. Prior to development of site plans, Consultant will verify previously established design criteria
associated with ozonation and disinfection.
Consultant will schedule a project definition meeting with the City to discuss the revised site plan
alternatives and establish agreement on the preferred site plan alternative. Consultant will provide meeting
minutes following review meeting. Decisions made during the project definition meeting will be
incorporated in the revised Implementation Plan.
Assumptions:
· Site plan development to start after treatment process confirmation workshop and decisions.
Deliverables:
· Workshop presentation and minutes documenting revised site plan decisions.
4.3 Revised Implementation Plan
The previous Implementation Plan developed for the new Butterfield WTP was based on new facilities and
treatment processes being constructed on the existing Butterfield WTP site, which necessitated phased
construction to appropriately sequence construction and demolition efforts. A Class 5 (AACE International)
cost estimate will be developed, based on the proposed site plan and treatment process. Consultant will
revise the Implementation Plan, accounting for changes to site location, project schedule and phasing
needs, cost estimate, and funding.
Consultant will provide City with a draft revised implementation plan. City will provide review comments in a
Bluebeam Revu Studio Session coordinated by Consultant. City will internally reconcile its review comments
to provide clear direction for Consultant. Consultant will provide a written response within the Bluebeam
Revu Studio Session to each written review comment provided by City and incorporate the comments into
the final revised implementation plan accordingly.
Assumptions:
· Design treatment capacity remains unchanged. Space for future expansion will be considered for
site plan development, but not cost estimated.
· Ozone and direct filtration will still be utilized and design criteria associated with flocculation and
filtration remain unchanged.
Deliverables:
· Draft and final version of the revised Implementation Plan.

4.4 Revised Hydraulic Profile
Consultant will conduct a hydraulics evaluation to confirm impact of building on the greenfield site on the
raw water pump station capacity. The evaluation will include whether the existing pumps can achieve the
firm capacity of 30 mgd at the greenfield site using the existing design condition of the raw water pumps.
This study will utilize the pump hydraulic model built as part of the early works design. This study will
evaluate the need for the City to upgrade pumps 6 and 7 under Early Works to achieve the higher total
dynamic head (TDH) that is needed to each convey 10 mgd to the existing Butterfield WTP, which has a
grade elevation that is about 14-feet higher than the greenfield site. Pump replacement recommendation
will include consideration of modernization and maintenance schedule on aging infrastructure.
Deliverables
· Revisions to the Raw Water Pump Station Capacity and Hydraulics Evaluation Technical Memo
prepared under Early Works design.
