Swanswell Viaduct project, Coventry

As part of the Coventry Ring Road Improvement scheme, our Balvac team strengthened and refurbished Swanswell Viaduct, reducing the ongoing maintenance costs and extending the lifespan of this critical asset.

Commissioned through the SCAPE Civil Engineering framework, Balvac was engaged at pre-construction stage to develop the designs to upgrade the original 1960’s concrete cladding panels and edge beams with an enhanced stringcourse detail, using both pre-cast units and in situ reinforced concrete.  

After many years of heavy use and exposure to the elements, the original post-tensioned concrete box beam structure required extensive refurbishment. We installed a new modern Trespa cladding panel system, a new vehicle restraint system, complying to current standards, along with bridge deck waterproofing and re-surfacing works.

Other works involved:

  • Removal of existing ‘white spar’ fascia panels and reinforced concrete edge beam
  • Replacement of bridge deck and sub-surface drainage including connections into surface level drainage network

Positively impacting the local community

Balvac's project team worked closely with the local community and two social enterprises to generate social value and leave a positive legacy. This included a summer placement for a local student and held sessions on CV writing and interview techniques for The Princes Trust in Coventry. In addition, the team donated food and volunteered at Coventry Foodbank, who provide emergency food for people in crisis.  

The team also diverted over 99.8% of 610 tonnes of waste materials from landfill.
