Innovations

The Eliminator Waterproofing System was applied to the bridge deck which allowed the works to be completed in sections for highway vehicle use. 

 

Matterport 3D visualisation system was used as a pilot project. These visualisations were used to provide dilapidation surveys, weekly progress reports and handover files.

 
Benefits / Project Outcome
  • The repairs and remediation works were carried out successfully to the bridge deck which ensured the structure could be used and fit for purpose for the next generation.

  • Additional safety features were also installed by introducing highway impact barriers to the structure where previous vehicle crashes had occurred.
