Public Works Standards & Specifications Manual
This version of the Missoula City Public Works Standards & Specifications Manual (MCPWSS) is in effect from December 1, 2021, until its next update. All projects that have not yet submitted Stage 3 of the Public Infrastructure Review Stage Process must follow the standards and specifications, stage checklists, and standard drawings for the manual version shown below.
All projects with Stage 3 submitted between November 18, 2020, and November 30, 2021, may continue to follow the standards and specifications, stage checklists, and standard drawings for the 2020-21 PW Standards & Specifications Manual version (link also at left), or the project engineers may follow this newest version of the manual if they so choose.
Projects with Stage 3 submitted before November 18, 2020, will continue to follow the previous standards and specifications versions and stage checklists in place before the MCPWSS was in effect. They can be found on the Development Services web pages here.
