Explanation

1. BACKGROUND: This Ordinance authorizes the Director of Public Utilities to renew the professional engineering services agreement with CH2M HILL Engineers, Inc. for the Parsons Avenue Water Plant Hypochlorite Disinfection Improvements Project, Capital Improvements Project No. 690487-100000, Division of Water Contract No. 2133.

The overall project will convert the PAWP disinfection process from the current gas based chlorine system to a liquid sodium hypochlorite disinfection system. CH2M HILL will provide Professional Engineering Services for the project.

The original agreement provided preliminary design services.

Renewal No. 1 (current) will provide detailed design and bidding services.

The Parson Avenue Water Plant serves multiple planning areas so this project is coded as “99 - Citywide”.

1.1 Amount of additional funds to be expended: $1,632,300.00
Original Contract Amount: $ 589,800.00 (PO050804)
Renewal #1 (current): $1,632,200.00
Renewal #2 (future): $1,342,000.00
Total (Orig. + Renewal #’s 1-2): $3,564,000.00

1.2. Reason other procurement processes are not used:
This renewal was planned and identified in the original contracting legislation Ord. 2896-2016, which called for detailed design services and engineering services during construction.

The current consultant is familiar with the project and has completed all the preliminary design work to date. Bidding the work to another consultant will delay the project and will result in higher costs due to bringing the new consultant up to speed on the project and delay the timeline for replacing the existing chlorine gas system.

1.3. How cost of renewal was determined:
The Consultant prepared an estimate based on the scope of work for the detail design renewal. City Project Manager and associated staff reviewed and approved these cost summaries.
