(used on projects referencing 2013 ODOT C&MS in the Contract Documents)
A significant modification to ODOT’s concrete specifications has been adopted in the 2013 Construction and Material Specifications (C&MS) book. Projects bid under the 2013 specification will be identified as either concrete with or without QC/QA (pre-determined by designer based on quantities) for new QC class designations. New supplemental standards as well as a new specification items have been added to reflect and adopt these revisions and are listed below. Note that small quantity, miscellaneous concrete will not require full QC requirements.

Note: Any updates/changes occurring on items in the 2013 C&MS specifications book are identified in Supplement Specification 800 while updates to individual Supplements are modified separately with the new effective date which all supersede the existing specifications.
