CIP Monthly Status Report – March 2017

Construction at the RWF
In March, the Tunnel Rehabilitation Project advanced through the first stage gate (Approve Project Scope) in the Project Delivery Model. This project will rehabilitate and repair critical portions of the 4.7 miles of tunnel infrastructure beneath the RWF.

The City rejected all bids received in December 2016 for the Headworks Critical Improvements Project to make clarifications to the Statement of Bidder’s Experience specification. The project has been readvertised in March.

The alternatives analysis work for the Aeration Tanks Rehabilitation Project kicked off this month. Alternatives analysis efforts also continued for the Filter Rehabilitation, Nitrification Clarifier Rehabilitation, Facility-wide Water Systems Improvements, and Digested Sludge Dewatering projects. Conceptual design continued on the Advanced Facility Control and Meter Replacement Project. The Blowers Improvements Project reached the 30 percent design milestone. The Headworks Improvements and New Headworks project team advanced the basis of design and procurement documents.

Testing and commissioning continued successfully on the Digester Gas Compressor Upgrade and Emergency Diesel Generators projects. The new emergency diesel generators passed a key “black-start” test to verify correct automatic operation when the RWF is isolated from PG&E-supplied electrical power. Major construction continued for the Digester and Thickener Facilities Upgrade Project. Staff continued to coordinate process shutdowns, isolating sections of the RWF to allow the contractor to reroute utilities necessary to allow construction to progress.
