The project was a design and build development of Oakleigh Road South Vehicle Depot to create a Barnet Council vehicle depot and a base for their fleet of 46 household recyclable waste collection vehicles.

The Challenge

There were several challenges faced throughout this project. There was restricted access on a long and narrow site which caused difficulties when trying to overcome other challenges such as dealing with the below ground water, removing underground drainage structures and the buried hazardous waste.

The Solution

To overcome the narrow site, the Willmott Dixon team worked in a ‘patchwork’ fashion, sectioning off the works and moving operations around to keep the access road fully open throughout the build.

Willmott Dixon found existing sewers and then got permission from Thames Water to use them instead for the below ground water. They found a solution using a land drain pump to drain the ground water which was causing surface water.

The Results

Now built, the depot will allow Barnet Council to operate its vehicle maintenance and recycling collection fleet from single coordinated site, ensuring the most efficient service for residents across the borough. The construction also consisted of a tractor barn and car parking, together with associated ancillary facilities, a recycling waste transfer building and bulking facility, a two storey office and welfare building.
