Qualified Manufacturers List

This Standard specifies requirements and procedures for a certification system that shall be applicable to all referenced manufacturers, as well as suppliers and contractors within certain industries. Certifying a Manufacturer’s Quality Management Plan is not an automatic acceptance of any particular product, but an acknowledgement that the Manufacture has taken steps to ensure that their quality controls meets the applicable Industry standards. Manufacturers whose Quality Management Plans are acceptable will be placed on the Qualified Manufacturers List (QML).

1. Scope

1.1  The Standard Practice for Quality Management Plans and the Qualified Manufacturers List is also referenced as Colorado Procedure (CP) 11.

1.2  This Standard specifies requirements and procedures for a certification system that shall be applicable to all referenced manufacturers, as well as suppliers and contractors within certain industries. Certifying a Manufacturer’s Quality Management Plan is not an automatic acceptance of any particular product, but an acknowledgement that the Manufacture has taken steps to ensure that their quality controls meets the applicable Industry standards.

1.3  The complete document CP 11 duplicates in its entirety the information presented in the most recent CDOT Field Materials Manual (FMM).
