MLM were commissioned by National Grid to carry out inspection and report on 3 high pressure gas main pipe bridges in Sheffield. National Grid were concerned that the pipe bridges had suffered damage in the severe flooding of northern England in 2007.

A number of defects were noted, the worst of which was a large tree of historical interest that had grown around one of the gas pipelines. The tree had exerted a force on the pipeline that had been exacerbated in flood conditions, causing the pipeline to move at its bearings.

Key Features

  • 3 pipe bridges in Sheffield, thought to be damaged during an extreme flooding event.
  • The 3 pipe bridges were the subject of a structural inspection.
  • Reports produced outlining the defects, likely causes, ongoing vulnerability and providing recommendations for remedial works.
