III. DESCRIPTION/BACKGROUND
Project Purpose
This project will abandon and replace nine (9) Pressure Reducing Valve Stations throughout Redmond. The majority of these should be replaced in the same location, but a few will need to be relocated due to difficulties of construction or maintenance access. The construction will provide for installation of new vaults, valves, piping and restoration of all street, sidewalk and landscape within the limits of construction.
Background
The City uses approximately 84 PRV stations to manage water pressure in the City’s distribution system. Many of these PRV stations were built in the 1960’s and 1970’s and are in need of refurbishment. The MOC staff inspected and evaluated all of the City’s PRVs and generated a list of 27 PRVs that needed to be rehabilitated or replaced. These PRVs have aged and degraded to a point that they no longer meet the City’s standard due to pipe corrosion, age, type of materials used, and environmental conditions. Corrosion is the main cause of degradation, but other issues include vault drainage and safe access. Ten (10) of the 27 valves were replaced under Phase 1. An additional nine (9) will be replaced with Phase 2. Attachment 1 shows the location of these 9 PRVs. Attachment 2 shows an example of an existing PRV installation.
Consultant Selection Process
A Request for Qualifications (RFQ) was issued in November 2019 for a consultant to develop preliminary and final designs, prepare permitting documents, provide support to staff in the acquisition of utility easements, prepare plans, specifications and cost estimate for bid advertisement, and provide construction support for the project. Two firms responded to the RFQ - BHC Consultants and RH2 Engineering. After a review of proposals by staff from construction, utility engineering and utility operations, BHC was chosen for the project. The scope and fee for the Consultant was negotiated in December and January. Attachment 3 shows the resulting Consultant Agreement with BHC.

B. Fiscal Note:
Estimated costs for this project are shown below:
Current Project Budget:

Estimated Project Costs
Design and Permitting $733,000
Easements and other property rights $695,000
Final Design $890,000
Construction $4,830,000
Total $7,148,000
VI. ALTERNATIVES TO STAFF RECOMMENDATION
The City Council could choose not to approve this Consultant Agreement at this time and direct staff to continue to negotiate the scope of work and the fee estimate with the Consultant. This would delay the start of the project.
VII. TIME CONSTRAINTS
This project is scheduled to begin construction in the summer of 2022 due to the long lead time needed to acquire utility easements from private property owners on several of the project sites. The project may be able to begin earlier if the acquisition process goes more quickly than expected.
