UK Power Networks roadworks this spring/summer

We've been advised of a major mains laying scheme that UK Power Networks will be undertaking in the Borough as follows:
UKPN, as part of a £360million investment into the networks they own and operate in London, South East and the Eastern region are carrying out a £6.6million scheme in the Borough to install a new high-voltage underground cable between the sub-stations in Whytecliffe Road North in Purley and Court Wood Lane in Forestdale as shown on the attached route here (this takes you to a larger version of the small image map illustrating this post).
The first phase of the works is due to start on 3 March 2014 on the section of the route from Whytecliffe Road North to Sanderstead Road. This will be undertaken with 2 gangs working simultaneously from Whytecliffe Road North and Penwortham Road. Works will then start on the remainder of the route in June 2014.
The process starts with excavation in up to 100m lengths, which can take up to five days depending on what is found under the ground in the form of other utilities, sewers etc. Ducts are then laid and the road will be progressively reinstated. A maximum length of 100m will be excavated at any one time. Approximately every 500m a joint pit will be constructed at convenient locations. This will either be done as the ducts are laid or by a return visit ensuring the excavations are left open for the minimum time. A concrete base will be laid in the joint pit which will take 3 days to cure. Cable is then pulled through the ducts, the cables jointed and the road reinstated.
UKPN will be issuing a press release and delivering the general letter attached to all properties on the route and to Resident’s Associations over the course of next week. They will also offer to give presentations to the Residents Associations if required. A site-specific letter will be delivered to properties in each road 2 weeks before the works are due to start in that road and will give more details of the traffic management to be used, which will typically be temporary traffic signals and parking restrictions. Advance warning signs will also be placed in each road 2 weeks before works start.
Information will also be posted on the Council web site and be regularly updated as works progress. I will update this blog as more information becomes available about the impact on Sanderstead roads.
