Scope of Work
Amendment No. 2
City of Pasco
PWRF Irrigation System Improvements
Additional Work
September 2025
Background
The City of Pasco (City) has selected RH2 Engineering, Inc., (RH2) to provide professional services to
design and permit upgrades to its Process Water Reuse Facility (PWRF) Irrigation Pump Station (IPS),
as well as extensions and upgrades to the transmission and distribution of its treated and clean water
pipelines for its land treatment system (LTS). These upgrades are hereby referenced as the PWRF
Phase 4 Irrigation System Improvements.
During design, funding availability changed, and alternate sites for LTS expansion were chosen by the
City based on purchase/sale negotiations with landowners and comments from the Washington
State Department of Ecology (Ecology). Available funding and alternate sites affected the pipe sizing
and alignments for the LTS expansion. This amendment captures the level of effort necessary to
accommodate these changes and to provide limited support during construction. Subtask numbering
is continued from the original contact and previous amendments.
Task 3 – Analysis and Preliminary Design (30 Percent)
Objective: Determine the flow capacity of the IPS and the diameter of distribution mains and IPS
mechanical piping, and incorporate design elements into the preliminary design. Prepare a
preliminary Engineer’s opinion of probable construction cost (OPCC). RH2 will coordinate with Valley
Science and Engineering and Geophysical Survey as subconsultants to support this Task.
Approach:
Remove the U.S. Bureau of Reclamation (Reclamation) South and future Washington State
Department of Natural Resources parcels from the process water and fresh water hydraulic
model, and add future demands for parcels adjacent to the NE Reclamation parcel. Resize
proposed pumps and force mains to accommodate reallocated demands.
Revise the predesign reports (process water and freshwater) based on updated hydraulic
modeling efforts. Prepare a preliminary OPCC.
Assumptions:
•Piping to the NE Reclamation parcel (Circle 14) will be upsized to accommodate future acreage
to the east.
•City South (Circle 17) will remain in the hydraulic model.
•The SE Reclamation parcel (Circles 16a and 16b) will remain in the hydraulic model.

Provided by City:
• Input on future parcels and acres that could be incorporated into the LTS.
RH2 Deliverables:
• Updated predesign reports in electronic PDF.
• Preliminary OPCC in electronic PDF.
Task 5 – 60-Percent IPS and Pipeline Design
Objective: Prepare updated 60-percent design plans, specifications, and OPCC reflecting revised site
work, distribution system improvements, electrical and structural work, and updated
communication strategies.
Approach:
Remove the Reclamation South and City South parcels from the process water and freshwater
LTS distribution system design plans per City direction.
Upsize distribution piping going to the NE Reclamation parcel to serve adjacent parcels as
identified by the City.
Provide up to eight (8) hours of ground penetrating radar to locate buried utilities.
Incorporate utility linework into plans.
Conduct a site visit to evaluate the feasibility of using radio communication for three (3) new
pivots. Revise the design to incorporate radios in lieu of fiber, if feasible.
Prepare design for power and controls to the booster pump station (BPS) near Circles 13
and 14.
Update the OPCC based on proposed design updates identified in this Scope of Work.
Assumptions:
• The 60-percent review comments will be constrained to details that were developed
subsequent to the 30-percent review submittal, or that were revised or unresolved during the
30-percent review process.
• Fiber communication will be stubbed at the IPS and routed through the Blasdel easement.
• Radio communication will be used at the three (3) new pivots if determined feasible during
the site visit.
Provided by City:
• Timely review comments as markups on the 60-percent design plans and specifications.

RH2 Deliverables:
• 60-percent plans and details that identify the major site, structural, mechanical, and electrical
layouts, and related details in electronic PDF.
• 60-percent OPCC in electronic PDF.
Task 6 – 90-Percent IPS and Pipeline Design
Objective: Update the 90-percent design plans, specifications, and OPCC to reflect the updated
communication improvements, including the transition from fiber to communication at the pivots.
Approach:
Develop 90-percent design drawings incorporating the revised communication layout to
replace fiber with radio systems at the three (3) new pivot locations.
Update the technical specifications to reflect the radio communication equipment,
installation requirements, and integration with existing infrastructure.
Revise the 90-percent OPCC to account for changes in communication system components,
including removal of fiber-related costs and addition of radio equipment and installation.
Provided by City:
• Timely review comments as markups on the 90-percent design plans and specifications.
RH2 Deliverables:
• Updated 90-percent plans and details in electronic PDF.
• Updated 90-percent technical specifications in electronic PDF.
• Updated 90-percent OPCC in electronic PDF.
Task 15 – Services During Construction (Limited)
Objective: Provide limited engineering services during construction to support the City. As the
engineer of record, coordinate with the City, its designated utilities, and special inspector to respond
to technical questions and issues. Services will include reviewing limited technical submittals,
responding to requests for information (RFIs), performing on-site observations, and assisting with
change proposals and change orders.
Approach:
Review limited technical submittals, as requested by the City, for general conformance to the
project specifications. Provide written comments to the City.
Respond to contractor RFIs, as requested by the City. Document and transmit responses to
the City.
Perform limited on-site observations, as requested by the City, in coordination with the City’s
designated inspector(s). Provide brief field notes summarizing observations.

Assist with change proposals and change orders as requested by the City.
Provide programming and integration services for the controls installed during construction.
Programming will include programmable logic controllers (PLCs), operator interface screens
(OIS), and the computer-based supervisory control and data acquisition (SCADA) system. It is
assumed that the programming will be based on standard programming developed for the
City by RH2’s subsidiary, Control Systems NW LLC. Integrate the programming upgrades with
the existing City system, including connecting the existing Historian system to the SCADA
system programmed as part of this project. It is assumed that the City will purchase all
licensing and hardware needed for the SCADA portion directly from the vendor.
Observe the remote telemetry unit (RTU) components factory testing at the contractor’s
panel shop prior to installation in the field, as requested. Perform initial testing of the PLCs
and OIS on the RTU prior to installation in the field.
Provide observation and support during startup activities, including the final operation of the
project hardware/software components.
Review field records provided by the contractor and prepare construction record drawings
based on the changes.
Assumptions:
• It is anticipated that the City will be the lead inspector, lead construction contract
administration, and be responsible for day-to-day activities. A maximum of 1,105 hours have
been included in this Task to review technical submittals, respond to contractor questions,
provide limited on-site observations, assist with change orders, and provide programming and
startup services as shown in the attached Fee Estimate. If additional effort is needed, that
extra work will be mutually determined by the City and RH2.
• RH2 is not responsible for site safety, or for determining means and methods or directing the
contractor in their work.
RH2 Deliverables:
• Technical submittals in electronic PDF.
• Applicable RFI responses in electronic PDF.
• Field notes summarizing on-site observations in electronic PDF.
• Change order proposals in electronic PDF.
• PLC, OIS, and SCADA programming.
• Attendance at RTU factor testing.
