Request for Proposals - City of Chandler Sewer Assessment and Rehabilitation Program

• 81100000 - Professional engineering services

Project Description: The City’s wastewater collection system consists of over 935 miles of sanitary sewer pipeline, in addition to lift stations, force mains and diversion structures that collect and convey wastewater to three water reclamation facilities (WRF). The Public Works and Utilities Department administers a Sewer Assessment Program. The purpose of this program is to assess the structural and operational condition of pipelines, structures, and facilities. The results of these assessments, combined with hydraulic modeling and capacity analysis, will be used to prioritize and execute rehabilitation, repair, and replacement projects.

The Program is anticipated to start in early 2026 with a five year budget of approximately $25,000,000.

These prior sewer assessment reports are being provided for reference only and are available upon request. Please contact Kurt Mahoney at kurt.mahoney@chandleraz.gov to request a download link for the following documents:
•           Manhole Assessments 2022 Final Report (WW2209.201)
•           City of Chandler Sewer Pipeline Assessment and Rehabilitation – 2021 (WW2005.201)
•           Manhole 2020 Priority Streets Manhole Condition Assessment - Final Technical Memorandum (WW2004.201)
•           Manhole 2020 Main Line Manhole Condition Assessment – Final Technical Memorandum (WW2004.201)

Scope of Work: The Program Manager may be contracted to provide a range of services, including system-wide program management and project development for sanitary sewer rehabilitation, repair, and replacement projects.  The goal is to develop a program for implementation to address approximately 7,000 sewer manholes and approximately 10 miles of gravity sewer mains, with a focus on ductile iron pipe (DIP) and T-lock systems. This program will be funded over a 30-year period.

The services will also involve sewer system assessment through methods such as closed-circuit television (CCTV) inspection and other applicable techniques, followed by analysis and reporting of the assessment results. Additionally, the scope includes review of prior assessment, hydraulic modeling and capacity analysis, prioritization of repair and rehabilitation activities based on severity, planned roadway improvements, and water main replacement projects.

The Program Manager may also provide engineering design, post-design services, construction management support, stakeholder coordination with other City departments and external entities, and real estate support, including title reports, exhibits, and research. Technical competence, specifically in sewer design and rehabilitation, with expertise in various assessment and rehabilitation technologies or platforms. The intent of this RFQ is to award multiple contracts over a period of up to five years. The scope of work to include pre-design, detailed design, permitting assistance and construction management (if warranted).
