EXHIBIT A-4 — Scope of Work
Amendment No. 4
City of Renton
Highlands 435 Pressure Zone Reservoir Improvements
Phase 1 — 6.3 MG Reservoir and Transmission Main
Final Design
Professional Engineering Services
October 2019
Background
RH2 Engineering, Inc., (RH2) is currently providing engineering services for the design and bidding of
a new 6.3 million-gallon (MG)reservoir and 24-inch transmission main to replace the City of Renton's
(City) existing Highlands 435 Pressure Zone (PZ) reservoirs and transmission main, as well as other
associated improvements. While originally it was assumed that the project would be bid as a single
project, the City has decided to separate the project into multiple phases that will be bid and
constructed separately. Other changes have also occurred during the final design stage which have
affected the project schedule and increased the project complexity which has resulted in additional
design and engineering costs. Design for the Phase 1: 435 Zone and 565 Zone Water Main
Improvements was completed in June 2019 and documents submitted to the City. Design for the
Phase 2: Highlands 435 Zone Reservoir is at approximately 90-percent completion and is expected to
be completed and submitted for permits by Winter 2019/2020 to facilitate a Summer 2020
construction season. This Amendment is an authorization to revise the project Scope of Work and
Fee Estimate (Exhibit C-4) as described below to provide additional services necessary to complete
design and permitting efforts associated with Phase 1 and to provide professional services during
construction for Phase 1.
The estimated level of effort to complete the Phase 1 design was not commensurate of the level of
complexity associated with the installation of the proposed improvements within the NE 12th Street
corridor. Specifically, the full extent of the congested/constraining nature of the utilities within the
NE 12th Street corridor was not identified until after the topographic survey and follow-up
geotechnical and subsurface utility investigations were completed as part of the final design scope
of work. Further, the construction phasing and water system operational limitations further
compounded the efforts needed to complete the design for the off-site and frontage improvements.
Finally,the City has requested that RH2 provide additional design and permitting services to support
the utility coordination, construction permitting, and traffic control planning efforts currently
underway by City staff. Work associated with these tasks is expected to be performed as requested
by the City and on an as-needed time and expense basis, not to exceed the fee estimated in Exhibit
C-4.
The Scope of Work is amended to include the following amended and additional tasks.

SCHEDULES B AND C— OFF-SITE WATER MAIN AND FRONTAGE IMPROVEMENTS
Task B-3 .Off-site Water Main Final Design (Amending Scope and Fee)
Objective: Expand the scope of the final water main design tasks to include additional design services
to adequately detail the proposed improvements and to develop comprehensive phasing plans to
address operational limitations associated with the water system, the sequencing for construction
of the proposed improvements, traffic impacts, and timing for restorative efforts. Additional tasks
included the development of additional design drawings including details, upgrades to Highlands
Booster Pump Station (BPS), a pressure reducing valve (PRV) station, and construction phasing, as
well as the supporting advancements to the technical specifications and cost estimate and associated
quality assurance/quality control (QA/QC) reviews.
Approach
B.3.8 Prepare Additional Utility Design Documents — Provide additional design drawings as
necessary to address the proposed improvements and the associated challenges inherent
with the congested utility corridor and the operability of the water system during project
phasing. Update project specifications to address construction phasing requirements and
added design elements to facilitate water system operations.
B.3.8.1 Prepare design drawings for an added PRV Station and Highlands BPS electrical
improvements needed for construction phasing/operations.
B.3.8.2 Prepare ten (10) Detail Drawings for water system connections, temporary water
service, phased repurposing of existing water mains and roadway/corridor
restorations.
B.3.8.3 Prepare four(4) Construction Phasing and Staging Plans to outline the construction
requirements to maintain water system operations, minimize traffic and community
impacts, and timing for restorations.
B.3.8.4 Further develop Technical Specifications to address construction phasing ,
requirements and added design elements.
B.3.8.5 Perform QA/QC review of added plans and updated specifications.
