2023 Proposed Public Works Standards & Specifications Manual

2023 Proposed Updates to the Missoula City Public Works Standards & Specifications Manual

The Public Works & Mobility Department has been refining and updating the Manual since it went into effect on November 18, 2020. We would like your feedback on the changes proposed to go into effect January 1, 2023, so below we've included a redline version of the current chapter with the changes indicated by strikeout or underline in red. We've also included a "clean" copy that has the changes incorporated in the text. For an overview of the changes in a chapter, see the Summary of Changes document. Also included is a redline version of each appendix or other document that has proposed updates. Documents with only minor changes (corrected typos, formatting changes, etc.) are included below but do not have redline and clean versions.
