About this file

This is an addendum template document issued by the City of Phoenix Office of the City Engineer for design and construction procurement projects. The template provides a standardized format for issuing amendments to bidding and contract documents, with sections designated for questions and answers (Q1-Q4 with corresponding responses A1-A4) and organized categories for modifications including general provisions, technical specifications, and plan sheets. Bidders are required to acknowledge receipt of any issued addendum by referencing the addendum number and date on the proposal form (P-1). The template accommodates three types of document modifications: additions of new sections, deletions of existing sections in their entirety, and deletions followed by replacements with revised sections, with spaces provided to specify the document section, subparagraph, and page numbers affected by each change.

The document serves as a procedural tool to manage changes to contract documents prior to bid submission and does not contain specific pricing terms, contract award information, or project funding details. This template would be utilized for any City of Phoenix design and construction procurement project requiring clarifications or modifications to the original bidding documents. The related contract opportunity for Lift Station 66 and Lift Station 77 Wastewater Infrastructure Modifications—Construction Administration and Inspection Services, for which qualifications are due by 12:00 pm on Friday, April 3, 2026, through the City's Procurement Portal, represents an example of the type of project for which such addenda may be issued.
