UKSTT award winners for best high value pipeline renovation project of 2017

No-Dig experts gathered on 18 October to hear the results of the 2017 awards from the UK Society for Trenchless Technology (UKSTT) at its 23rd annual awards dinner.

Over 200 guests were welcomed by UKSTT chairman Matthew Izzard to the Met Hotel in Leeds for an entertaining evening, where awards were presented for renovations and new installations as well as innovation and environmental performance.

And the winners were …

Pipeline Renovation Award – over £250k (sponsored by Source One Environmental)

Winner: McAllister Group
Project: Bank Station – Low Level 2 Sewer Articulation.

Description: To facilitate the construction of a 570m tunnel as part of the Bank Station Capacity Upgrade Project, the McAllister Group working for Dragados had to control flows and articulate 11 joints inside Low Level 2 sewer beneath the station to allow it to move without being damaged when tunneling commenced.

Commendations:
  • Thames Water, Eight20 & McAllister Group – Forest Hill void emergency works
  • Lanes Group plc – Thames Water pipe repair rate increased with patches

Pipeline Renovation Award – under £250k (sponsored by RSM Lining Supplies)

Winner: UKDN Waterflow (LG) Ltd
Project: Culvert 799 set up for another 100 years.

Network Rail commissioned UKDN Waterflow (LG) to install a structural liner in a 35-metre-long, 1200mm-diameter, circular, brick-lined culvert under the railway in Kent. The team had to guarantee a 100-year lifespan for the liner — double that normally required. Access to the remote location of the culvert provided a further challenge.

New Installation Award (sponsored by Lanes Group plc)

This award recognises companies who can demonstrate their key roles in successful new installations of cables, ducts or pipelines using trenchless techniques

Winner: Severn Trent Water/BNM Alliance
Project: Elan Valley Aqueduct

The Elan Valley Aqueduct (EVA) was built over 100 years ago to serve the growing population of Birmingham.
