Project Name: Welling Way

 
Project Reference Number: SOE15368
Project Network: SGN

Scheme background: The Chaucer Road and Wickham Street project was a coordinated effort between Thames Water and SGN to minimise disruption to residents, businesses, and road users within the London Borough of Bexley. By working collaboratively, both organisations were able to deliver essential infrastructure upgrades while reducing the overall impact on the local community.


Thames Water's Contribution:
Thames Water carried out works along a 786-metre section, installing a new 250mm PE water main. This new pipe enabled the decommissioning of an existing 200mm ductile iron main. In addition all customer connections were renewed.

SGN's Contribution:
SGN completed significant gas network upgrades, which included Iinsertion of:

  • 360 metres of 75mm PE pipe
  • 3.5 metres of 125mm PE pipe
  • 501 metres of 180mm PE pipe

Abandonment of:

  • 250.5 metres of 200mm ductile iron (DI) main
  • 338.5 metres of 8-inch cast iron (CI) main
  • 192.5 metres of 6-inch CI main
  • 420 metres of 4-inch CI main

Collaborative Approach
The project was delivered through close cooperation between SGN and Thames Water, along with their respective contractors, JDT Utilities and J Browne. Both organisations operated within the same working area, which required proactive coordination.

In addition to scheduled planning meetings, supplementary discussions were held involving the Greater London Authority (GLA), Thames Water, SGN, and their contractors. These sessions focused on key topics such as:

  • Cost sharing arrangements
  • Traffic management planning
  • Division of responsibilities for excavation and reinstatement

This joined-up approach ensured the smooth progression of the project while minimising disruption for those affected.
