Client :                 Murphy Group

Location :           Radlett, Hertfordshire

Value :                   < £250,000

Remarks :            Project works were undertaken in two blocks across a period of 6-7 weeks in order to complete the installation of a new bridge, on time and to budget.

The key element of the project was the overhead line works. MECX had to ensure that existing overhead lines were decommissioned and removed and then – after the installation of the bridge itself – MECX had to ensure that the overhead lines were renewed, reinstalled and handed back.

Putting the bridge in was a standard engineering project, however it had to be managed in a specific way to ensure the project met all the requirements that overhead line works demand.

The details of the project included:-

  • The removal of the existing overhead line masts and support structures.
  • De-wiring the system and supporting the installation of the new bridge.
  • Re-wiring the overhead line.
  • Installing new overhead line structures.
  • Major cable diversions and temporary works to facilitate the main works.
  • Moving signalling equipment.
  • Drainage works.
  • Creating numerous access points and subsequently decommissioning the access points after completion.

Mainline closed to complete the works

The location of the site meant the mainline had to be closed to complete the works, which resulted in a challenging timescale. The series of interfaces that had to be managed – such as the TOCs, FOCs and third parties such as the highways, local farmers and local residents – made for further complexities. However, MECX provided all the support that was required and therefore the challenges were overcome and the works were delivered successfully, on time and to budget.
