BRS lane closure 30 November to March

HS2 Notification: Breakspear Road South lane closure from 30 November 2020 to March 2021;

Posted on Nov 13th 2020 by HS2 in Hillingdon

Lane Closures:

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 description

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 pilling

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 piling

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.

Construction work

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.

Local roads

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.

HS2 – Imminent Traffic Impacts

Fancy a detour?

We are creating two new site entrances and building crossing points for a haul road on the A412 near Denham Water SkiClub on Moorhall Road. This work is in preparation for the creation of a new haul road to support the construction of the Colne Valley Viaduct.

In order to carry out this work we need to put in place a full road closure on the A412 road over two weekends:

  • Closure between 21:00 30th October and 05:00 2nd November
  • Closure between 21:00 6th and 05:00 9th November

What to expect
Signed diversions for traffic on A412 traffic Weekend closures
Some additional traffic on local diversion route
Marshalled access for residents affected by the closure
The diversion route shown above

Sheet piling works in West Ruislip from 19 October for three weeks

Sheet piling works in West Ruislip from 19 October for three weeks
Sheet piling works will begin at the West Ruislip site on 19 October. The works are expected to last three weeks.

What we are doing
From the week commencing 19 October we will carry out sheet piling works inside the construction site at West Ruislip. This work will help us to install a temporary tank to be used as stormwater drain to prevent flooding in the work area.
Sheet piles will be installed in sequence along the planned excavation perimeter to provide temporary walls within the ground to support our water tank. A mechanical machine will be used to push steel sheets into the ground.

How this work might affect you
A piling rig, cranes and construction machinery will be visible in the area
during these works.
The project team will take every measure to reduce noise impacts, however
you may notice some construction related noise and vibration.
Sheet piles will be pressed into position. In the event that we find hard
ground or obstacles, a vibro-hammer will be used to disturb the ground and
drive the sheets through the hard areas. Should this method be required, it
will be used for approximately one hour per day.

Duration of works
The activity will take place from w/c 19 October for three weeks.
Hours worked will be Monday to Friday 8am to 6pm and 8am to 1pm Saturdays.
We may be on site for an our before the start and/or end of each shift.

What to expect
Delivery and set up of equipment, cranes and piling rigs.
Our piling methods may involve vibrating piles into the ground.

What we will do
Conduct noise and vibration monitoring to ensure works are within project approval limits.
Use water carts to reduce the amount of dust
