1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify (Mod #1) an existing engineering agreement with Brown and Caldwell for Professional Engineering Services (Design Professional, or “DP” services) for the SWWTP Digestion Process Expansion project, CIP 650353-100003. This contract will provide Preliminary Design Services (Step 1), Detailed Design and Bidding Services (Step 2), and Services During Construction (Step 3) for this project. The initial phase of this contract provided Professional Engineering Services for Preliminary Design (Step 1) and Professional Engineering Services for Detailed Design and Bidding Services (Step 2).

This modification is for a redesign of the original SWWTP Digester Process Expansion and will keep the design for the Digester 6 cover, Digester 7, electrical building, digester boiler system rehabilitation, and rehabilitation of Digester 1-5.

A future renewal will be requested for Step 3, Engineering Services During Construction, which will include technical project representation (TPR) duties, construction-phase engineering, start-up and commissioning assistance, and record documentation. Construction Management Services will be performed by others.
