Departures from Standard

Standards in DMRB prescribe the technical requirements that have to be met in the design Roads Service schemes. Where these Standards cannot be met and there is no provision in the Standard for a lesser requirement (a Relaxation), a Departure from Standard must be sought.

Only the Director of Engineering has the authority to authorise Departures from Standard. The procedures to be followed are:-

1. Departures from Standard must be highlighted by Design Organisations and approval obtained.
2. Requests for Departures shall be completed in detail on the attached pro-forma and submitted to Divisional Project Managers. Submissions shall be signed by a Chartered Engineer within the Design Team.
3. If the Director of Engineering approves the request, the application will be signed and returned.
