CDOT Releases New 2019 Edition of Construction Specifications

06-Aug-2019 to 19-Nov-2019

On July 31, the CDOT Standards and Specifications Unit published a new 2019 edition of the Standard Specifications for Road and Bridge Construction. This supersedes the 2017 edition and is to be used on all CDOT construction projects advertised for bid after October 1, 2019. It is available as a PDF download from CDOT's website. This marks the first annual publication of the "Spec Book." Future years will follow the same publication schedule which is a much more frequent schedule than past years. 

One notable change is that beginning with this edition, the page size will be formatted to 8.5"x11" to allow for easier printing. Previous versions were 6"x9" page size. Additionally, page numbering is now specific to each Division of the book. For example, in the 2019 book, Division 100 is numbered 1-1 through 1-119. Division 200 is numbered 2-1 through 2-89. If kept in a three-ring binder, this allows users to swap out a single Division if that content has changed in the future. Unchanged Divisions can be kept in the binder and will not need to be reprinted, as page numbering will not be affected. Significant changes from the previous 2017 edition, can be found at
