SUBJECT
Title
Action on an Agreement with Mott MacDonald Group, Inc. for Annual Sanitary Sewer Condition Assessment Repair Projects (2021, 2022, and 2023 Projects) [Council Pillar: Deliver and Enhance High Quality Efficient Services and Infrastructure]
Report
BACKGROUND
The Water and Sewer Utilities Department manages the Sanitary Sewer Condition Assessment Program using the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP) guidelines.

The Department of Public Works procures outside construction contractors for repairs that are more complex due to factors such as traffic control, pipe size, pipe depth, flow, location, or an alternative type of repair method. Approximately 30 pipeline segments were repaired under Public Works construction contracts in FY 2019/20. Approximately 40 pipeline segments have currently been identified by the Water and Sewer Utilities Department for repair in 2021. In order to prepare the sewer repair construction contracts for public works bidding and due to the complexity of the repairs and resources, the City will need to hire a design consultant to provide engineering services for the 2021 and subsequent years' annual repair projects.
DISCUSSION
