The City of Portland Standard Construction Specifications apply to all public improvements and work in the City rights-of-way. The book is a collaborative effort between BES, PBOT, PWB, Procurement Services and the City Attorney's Office. The City Standard Construction Specifications are patterned after the 2018 ODOT/APWA Oregon Standard Specifications for Construction with modifications to accommodate the issues typical to the urban city environment.  Special Provisions are updated on a regular basis and posted on this web page when a standard specification needs to be modified or updated.

 If you have comments or questions regarding the specifications, please contact Jason Grassman at 503-823-8669 or
