Project Overview

Design and construction of 1.5km of new highway along with a four arm roundabout, cycle and footpaths, drainage, service diversions, environment protection and remediation.

Works included: 

  • 5km of 7.3m wide carriageway and 3.0m wide foot/cycleway
  • Four arm roundabout
  • Accommodation works
  • Diversion of Publicly Owned Services
  • Drainage
  • Remediation of Contaminated Land
  • Landscaping
  • Traffic Management 

During the design stage the whole team worked together to identify value engineering opportunities as well as managing innovations in terms of cost effectiveness, environmental impacts and local benefits. We also involved Constructing Excellence prior to construction, who provided advice on the possible use of waste materials particularly PFA.  

Several design changes were instigated which contributed greatly to buildability, sustainability, cost and time. This included value engineering drainage solutions to minimize fin drains, a value engineering pavement design to minimise sub-base thickness and replacement of conventional RC headwalls with sand bagged solutions. We also changed the design to maximize the use of PFA as fill which vastly improved sustainability and carbon footprint. 

The project was completed three months early, delivered to tendered cost, despite significant changes. We also delivered significant community benefits, in line with Welsh Government targets, including employment and training for long term unemployed. 

The project was registered as a Constructing Excellence Exemplar project and was a finalist in the 2013 Constructing Excellence Integration and Collaborative Working Award. The project also received the 2013 ICE Roy Edwards Merit Award.
