HS2 Notification: Breakspear Road South lane closure from 30 November 2020 to March 2021;
Posted on Nov 13th 2020 by HS2 in Hillingdon
We are building a crossing point for our internal haul road across Breakspear Road South to reduce the number of lorries using local roads. This will be located just to the north of the Chiltern Line Bridge and will be controlled by automated traffic signals.
What to expect
The lane closures will be controlled by automatic signals supported by operatives during the busiest parts of the day.
We will be using the current kerb areas to keep the open lanes as wide as is possible whilst the works take place, with the verges hardened to prevent damage.
What we will do
We will ensure that the need for pedestrians to cross the road is included in our light phasing.

Piling works in Hillingdon from West Ruislip Portal to Harvil Road from 30 November to Spring 2021.
Piling works will begin in late November throughout Spring 2021 to make way for the foundations of:
o the new road bridge at Harvil Road (over the Chiltern Line and the new high speed railway)
o the new rail bridge at Breakspear Road South
o the reconstruction of the footpath bridge over the river Pinn
o the new railway embankment at West Ruislip
Piling work is crucial to the stability of the ground and to distribute the weight of a constructed structure evenly. It is an effective approach to combating corrosion and is proven to significantly improve the life expectancy of a structure. Several different types of piles will be installed, such as bored piling and sheet piling.
Bored piles are a commonly used form of foundation that provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.
Bored piles require the removal of earth to form a hole for a reinforced concrete pile which is poured in situ. Bored piles are drilled using buckets and driven through rotary boring (twisting in place).
Sheet piles are commonly used for retaining walls, land reclamation and underground structures. These are sections of sheet metal with interlocking edges that are driven into the ground to provide earth retention and excavation support.
Sheet piles are installed in sequence along the planned excavation perimeter. When arranged together, they form a wall for permanent or temporary earth support, along with anchors to provide extra lateral support.
Hours of work
Standard construction hours are Monday to Friday from 8am to 6pm and Saturday from 8am to 1pm.
Specific work activity may occur outside of these hours, including concrete works and works along the
Chiltern Line during rail possession. When work is due to occur outside of standard hours, we will notify you.
Noise, vibration and dust
To reduce the impacts from piling works, noise generating activities are scheduled after 8am during standard construction hours where possible.
Noise and vibration monitoring will be conducted to ensure works are within project approval limits.
Sheet piles will be pressed into position. In the event that we find hard ground or obstacles, a vibro-hammer will be used for a short period of time to disturb the ground and drive the sheets through the hard areas.
Water carts will be in used to reduce the amount of dust generated by construction activities.
There will be some temporary traffic changes to ensure the work zone is safe. Lane closures will be in place and may affect travel times on Harvil Road.
There will be no changes to any of the other roads as you travel through the rest of the area. However, there will be heavy vehicle movements and deliveries of equipment to the work sites prior the beginning of the piling activities.
Large machines, workers and heavy construction machinery will be visible in the area during these works.
Equipment and machinery used will include piling machines, piling rigs, trucks, excavators, cranes, lighting towers, concrete equipment and trucks, light vehicles and hand tools.
