Each volume of the DMRB is focused on a particular aspect or group of aspects of highway or highway structures design or assessment. Continuing with this theme the agency has also introduced a new volume of the DMRB bringing together those parts of the DMRB that are generally applicable to all types of design for highway works covered by the manual.

The revised Introduction to the DMRB will be in this new Volume along with the indexes. It will also include standards such as "Quality Management Systems for Highway Design".

Standards and Specification Policy Team leader, Mike Weller, said:

"The changes are in response to feedback from people who use the documentation. They are designed to make general documents in the DMRB easier to find and clarify the requirements for Departures from Standards."
