UK A477 Trunk Road Improvement wins major collaborative Working Award

The £47m A477 improvement scheme between St Clears and Red Roses in Carmarthenshire, South Wales has just triumphed in the Integration and Collaborative Working category at the Constructing Excellence in Wales (CEW) Awards 2014.


One of the biggest events in the Welsh construction calendar, the awards showcase projects that have taken Wales forward and demonstrate that collaborative working is the best way of meeting Government targets and delivering a first class infrastructure for Wales.

The new A477 route, which was officially opened in April this year, forms part of the Trans European Road Network (TERN), a strategic route linking mainland Europe with West Wales and Ireland. The 9.6km section consists of 8.8km of off-line new build and 0.9km of on-line improvement. Construction features included 15 new structures and improvements, alterations to two existing structures, including the Grade 2 listed Pont Newydd (bridge) and three sections of wide single 2+1 carriageway (forming more than half the length of the route), plus two significant rock cuttings.

Ramboll undertook a significant role in the delivery of the scheme following appointment as Contractor’s Designer in 2009 for Key Stage 3 which was constructed under an Early Contractor Involvement (ECI) contract.

Throughout our involvement, we worked closely with the main contractor, SRB Civil Engineering UK Ltd, the client Welsh Government and key stakeholders, developing the scheme sufficiently to bring it to Public Inquiry and gain approval for construction. We also ensured that environmental commitments were met and enabled constructability of the detailed design, providing highways, structures and geotechnical design together with environmental design and management.

Describing the A477 improvements as “an exemplar project for the whole industry on how to deliver a landmark scheme collaboratively” the CEW judges were also particularly impressed by its partnership charter. This not only enshrined “a non-confrontational approach and open door policy that allowed the client to work as closely as possible with its supply chain partners” but also “embedded a culture that supported integration and collaboration.”

The scheme has also recently secured a CEEQUAL (Civil Engineering Environmental Quality Assessment) Excellent Whole Project Award with a score of 90.4%.
