News on HS2 in Hillingdon

25 October 2017

Please note that the scope of works for the utility surveys has changed. The works were originally intended to be utility trial trenches. However we have been able to change these works to Ground Penetrating Radar (GPR) surveys and pavement cores, which will be less disruptive as they can be completed in a shorter time span and are less intrusive. The works will still take place within the half term window but from Friday 27 October to Sunday 29 October .

GPR uses radar pulses to create a profile of what the ground looks like beneath the surface, including the presence of voids which indicate the presence of utilities. Pavement core involves coring a small piece of the road and sending it for examination and laboratory testing to determine its make-up.

We apologise for the change to what we previously notified you about and any inconvenience this may cause.

Please note that utility surveys are due to take place on Breakspear Road South on 21 October and are expected to be completed on 29 October .

For the duration of these works, the road will be reduced to one lane (the closed lane will alternate as the work demands). However, access to the road will be maintained and traffic management will be in place.
