Arup and Atkins will work in a joint venture along with RPS Environmental and Knight Architects to provide design development services to CVC.
As we reported last week, the Welsh government has signed up the Costain Vinci CVC joint venture on an early contractor involvement (ECI) basis for the scheme.
The scheme envisages improving the M4 Corridor around Newport. It includes construction of 24km of new motorway and a 2.5 km long cable-stayed viaduct crossing of the River Usk, as well as major remodelling of M4 junctions 23 and 29.
Scheme development work has now begun, leading up to an anticipated public local inquiry in winter 2016/7. Assuming statutory processes are completed, construction could start in spring 2018.
