Subregional operating group southern avenue interceptor rehabilitation projects 1, 2, 3, & 4

The City of Phoenix is soliciting qualifications for the Subregional Operating Group Southern Avenue Interceptor Rehabilitation Projects 1, 2, 3, and 4, a procurement initiative involving Maricopa County and the City of Phoenix in Arizona. This qualifications-based selection process requires submissions through the City's Procurement Portal at https://procurement.opengov.com/portal/phoenix no later than 12:00 pm on Friday, March 13, 2026. The projects focus on the rehabilitation of the Southern Avenue Interceptor, a critical wastewater infrastructure component, with qualifications being the primary evaluation mechanism for contractor selection. Interested parties must demonstrate relevant experience through reference checks and team qualifications documentation, as outlined in the provided DESIGN-BUILD_TEAM_REFERENCE_CHECK_INSTRUCTIONS and CONSULTANT_REFERENCE_CHECK forms. The procurement documents, including the main project specification (215KB PDF posted February 19, 2026) and the subcontractor selection plan, establish the framework for evaluating bidder qualifications and prior experience with similar infrastructure rehabilitation efforts. Prospective bidders should monitor for any addendums issued through the standardized template format established by the City of Phoenix Office of the City Engineer, with acknowledgment of addendums required on submitted proposals.

The procurement materials indicate a structured evaluation process incorporating design-build team references and consultant qualifications assessments, suggesting potential set-asides or preferences for small business or disadvantaged enterprise participation through the subcontractor selection plan. While specific award values and budget ranges are not explicitly stated in the available procurement summary, the scope encompassing four separate interceptor rehabilitation projects suggests a substantial infrastructure investment. The solicitation emphasizes compliance with the City's standardized procurement procedures, including the requirement that all addendums be acknowledged and incorporated into final proposals. No current incumbent vendors or existing contractor information is specified in the available documentation, indicating this may represent new contract procurement or competitive reselection. Qualified respondents should ensure comprehensive understanding of all technical specifications and requirements contained within the main project document and submit complete reference documentation demonstrating team capability for complex wastewater infrastructure rehabilitation projects.
