PROJECT

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.

THE CHALLENGE

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.

OUR SOLUTION

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.
