T0593 GD 300 Revision 3

Description

National Highways Safety, Engineering and Standards' Road Design Group (the Client) is procuring technical consultancy services to support the continued improvement of National Highways' all-purpose dual carriageway network via further development of the GD 300 concept. The core objective of this Work Order is the development of a revision to Design Manual for Roads and Bridges (DMRB) document 'GD 300' that omits level 4 (motorway designation) and shifts the focus of the document to enhancements over and above the all-purpose dual carriageway baseline i.e., current levels 1-3. This work order will build upon work done as part work order T0448 that sought to develop the framework and underlying principles for delivery of the above. The ultimate objective of this Work Order will be the production of a major update of GD 300.
