Category: Engineering
Status: Open


The City of Dubuque adopted the Statewide Urban Design and Specifications (SUDAS) program, which consists of a construction specifications manual and a design manual, as the City’s standard in 2014. Also In 2014, the City developed and adopted the City of Dubuque Supplemental Specification which modifies and supplements the SUDAS Specifications manual, to better accommodate the City’s current payment methods, material preferences, installation methods, and testing requirements. The City revised and updated the original Supplemental Specification in 2020, but continued to utilize and apply three additional standalone specifications:

  • 2011 City of Dubuque Water Distribution Division Standards & Specifications for Water Mains and Appurtenances
  • 2019 City of Dubuque Street Lights & Traffic Signal Supplemental Specifications
  • 2021 City of Dubuque Minor Wastewater Lift Station Supplemental Specifications

The City of Dubuque recently adopted the 2023 Edition of the City Supplemental Specification to coincide with the 2023 Edition of the SUDAS specifications manual. The City’s Supplemental Specification only shows the changes that differ from the SUDAS standard specifications manual and also now incorporates the requirements from the previously standalone specifications. Additional minor changes, deletions, clarifications, details and formatting were also made throughout the new supplemental specification document. The City highly encourages all users of the SUDAS program and the City’s Supplemental Specifications to become familiar with the newly adopted 2023 Edition of the City Supplemental Specification manual.

The City understands that there are projects in various stages of design and development. The application of the 2023 SUDAS program and Supplemental Specifications will be applied as follow:

  1. All projects that have been formally submitted thru the City’s Development Review Team (DRT) Process, prior to this notice being posted, will be permitted to continue utilizing the 2020 edition of both the SUDAS Specification manual and the City Supplemental Specifications along with the standalone specifications, if the professional of record chooses to do so.

All Projects submitted thru the City’s DRT Process on or after the date of this notice will be required to apply the 2023 edition of both the Statewide Urban Design and Specifications (SUDAS) Program and the City Supplemental Specifications.
