White City Phase 3
Ground Stabilisation
In-situ stabilisation of the upper 300mm of soils to achieve 15% CBR for pile mat construction.
Earthworks & Site Preparation
Site strip, hardstanding breakout, superstructure removal and bulk cut and fill operations.
Pile Mat Construction
Geo-grid installation, imported 6F2 placement and pile mat construction to support future development works.
Project Overview
Dunton was appointed by St. James to undertake ground stabilisation and earthworks for Phase 3 of the White City redevelopment in London. The project formed part of a major mixed-use regeneration scheme that will deliver approximately 1,800 homes alongside commercial and leisure facilities including a cinema, gym and café.
The works included site clearance, hardstanding breakout, demolition of superstructures, bulk earthworks, ground stabilisation and pile mat construction. Due to the site’s location within a highly constrained urban environment, careful planning and close stakeholder coordination were required throughout the project.

The Problem
The site presented a number of logistical and engineering challenges due to its proximity to key transport infrastructure and the requirements associated with a large-scale city-centre development. Ground conditions required improvement to support future piling operations, whilst operational constraints demanded detailed planning to avoid disruption to surrounding infrastructure.
Challenges Faced
- Site located adjacent to infrastructure owned by Network Rail, Transport for London and London Underground.
- Large-scale redevelopment programme requiring robust earthworks and ground preparation solutions..
- Reported medium risk of unexploded ordnance (UXO) across the site.
- Temporary sheet piling required to facilitate access to proposed basement areas.
- Pile mat design, methodology and piling equipment specifications required review and approval.
- Detailed coordination required with multiple stakeholders prior to commencement of works.
The Solution
Dunton established dedicated soil treatment zones to facilitate screening, processing and removal of asbestos-containing materials. The programme combined remediation, enabling works and environmental management measures to safely prepare the site for redevelopment while protecting surrounding environmental receptors
Techniques Used
- Site strip and hardstanding breakout.
- Removal of existing superstructures.
- Bulk cut and fill earthworks.
- Off-site material removal and disposal.
- D-Found soil stabilisation of the upper 300mm of soils.
- Stabilisation to achieve 15% CBR for pile mat construction.
- Supply and installation of geo-grid reinforcement.
- Importation of 6F2 material and pile mat construction.
- Piling attendance and support services.
The Result
Dunton successfully delivered the earthworks and ground stabilisation package, creating a development-ready platform for the next phase of one of London’s largest regeneration schemes. Through effective stakeholder management and technical ground improvement works, the project progressed safely within a highly constrained urban environment.
