Case Study


Brewery Wharf

Client: St. James / Berkeley Group

Location:  Brewery Wharf, Twickenham

Contract Value: £516,000

Dunton Environmental successfully carried out the installation of a temporary working platform to enable installation of deep foundations together with the management of all surplus arisings to facilitate residential development.


  • Initial site investigation encountered hydrocarbon contamination within the made ground in the vicinity of an underground fuel tank.
  • The working platform required a bearing capacity of at least 500kPa with minimal settlement.
  • A surplus of 8,000m3 of potentially contaminated construction soils.
  • Site access and traffic management constraints.


  • A temporary working platform was provided from site won material. The platform was engineered to line and level incorporating a cut and fill operation over the site.
  • Management and separation of waste and classification in accordance with the EA Technical Guidance WM2.
  • Ex-situ bioremediation of hydrocarbon impacted soils by application of our Bio-AcceleratorTM to reduce waste classification and disposal costs.
  • Close liaison with local haulage companies and waste management facilities to ensure project programme delivery.
