Technical approval guidance
The purpose of this leaflet is to provide guidance to developers (private developers and others) and their designers on the technical approval procedures for highway structures.
DfI Roads require that technical approval shall apply to all proposed highway structures including private development i.e. to construct, assess, strengthen or demolish structures within or up to 6m of the highway boundary.
It shall also apply to other structures outside these limits which through failure could have consequences for the road user within the highway boundary.
