Gas roadworks on A4074 and Woodcote Way

Many have been delayed and inconvenienced by Southern Gas Network’s (SGN's) ongoing mains replacement scheme.  Therefore I thought readers would be interested to see SGN's intended programme of works for the remainder.  The following is from an RBC Highways Network officer:
Upper Woodcote Road – to date:
SGN's initial works and intension in Upper Woodcote Road, was to conduct the works using two different working methods:
  • Section 1 (Shepherds Lane to Hewett Avenue) was to be completed by inserting the new pipe inside the old, with the intension being a quicker progression of works, less scarring of the carriageway surface and less material use/wastage.
  • Section 2 (Hewett Avenue to Woodcote Way) was to be completed by excavating a trench in which the new pipe could be laid, as they would be unable to fit the new pipe within the old. 
Both methods would require the transfer of individual services on to the new pipe, the abandonment/decommissioning of the old pipe and the use of portable traffic signals to safely manage traffic around the working area.
SGN have managed to complete Section 1, but there were a number of engineering difficulties that slowed the progression of work. It was decided that SGN should not continue on to Section 2, as this would have carried the works in to the network’s busiest time, on the lead up to Christmas.

Woodcote Way:
SGN intend to complete the replacement of gas mains, located in both footways between Geoffreyson Road and Upper Woodcote Road, commencing early next week. They intend to insert the new main inside the old, one footway at a time, and hope to avoid the need for portable traffic signals.
Excavation works will stop by 19th December at the latest, with excavations being reinstated and the area tidied over Christmas. The earliest SGN will return to the area is 2nd January, although it is likely that works will not recommence until 7th January.
There is likely to be a further 2 weeks of work in the New Year, with works in Woodcote Way being competed around 21st January 2013.
Upper Woodcote Road – completion:
SGN intend to continue their works (as per Section 2 above) from around 21st January 2013 (following completion of works in Woodcote Way). The works will require the use of portable traffic signals and should be completed within 5 weeks, subject to any engineering difficulties.
