Notice of piling works St James Place

What we are doing

Upcoming piling works

We will be starting piling works on our site in St James Place in mid-March and expect to complete these works by the end of August.

We need to install bored piles to stabilise the ground whilst we build the new Curzon Number 2 viaduct on the site. This viaduct is part of a suite of viaducts which will carry the new HS2 line to the new purpose-built Curzon Street Station. Piling works are therefore the start of the permanent construction works on the site.

What we will be doing

We will start by preparing the piling platform. We will do this by excavating the ground up to 1.2m deep. The excavation will then be backfilled with up to 40cm of soil and compacted using a vibration free roller. We will then start installing bored piles in May.

Bored piles are used to form a foundation that provides support for structures by distributing the weight of the structure evenly across the ground. To install the piles will use a piling machine to drill a vertical hole deep into the ground. We will then lower the reinforced steel into the hole using a crane before filling the hole with concrete and finally capping them at ground level with a beam.

As we carry out this work you may notice deliveries of materials, construction equipment and machinery.

Noise and dust will be carefully managed throughout. Noise and vibration monitoring will be in place throughout these works. We will also use water sprays to reduce dust generated by construction activities.
