Civil engineering project with access bridge by David French Partnership

Civil Engineering Projects

Earthworks, level design, access roads and structures over live public highways.

Civil engineering schemes live or die on the earthworks. Our ground investigation service and in-house soils laboratory feed straight into the level design, which is what keeps the muck shift balanced and the budget intact.

Vauxhall Car Park Extension

This car park project comprised 29,000 square metres of new car park with access road and included a new pedestrian access bridge over a public highway. It extended an existing car park adding 1200 more parking spaces. The land is a narrow strip of derelict land along the face of the chalk escarpment, running approximately North-South adjacent to Vauxhall Way in Luton.

The original ground levels varied by over 30 metres and the formation was achieved using cut and fill with a muck shift in the order of 35,000 cubic metres. There were considerable amounts of tree and shrub growth, together with rubbish, on the site, and some contaminated ground. The whole site was modelled with PDS Ground Modelling Software.

The levels were designed and, allowing for the rubbish that had to be taken off site, we were able to arrange a cut and fill balance of the muck shift to within about 3,000 cubic metres of the net import.

David French Partnership initially designed the car park as a project for a private client. The scheme was taken over by Vauxhall Motors, and the area of the car park was increased to include other land. An Architect was also appointed who acted as Project Supervisor, while the engineering design was prepared by David French Partnership.

Ground modelling and level design

The whole Vauxhall site was modelled in PDS Ground Modelling Software, which is how we were able to balance a 35,000 cubic metre muck shift to within roughly 3,000 cubic metres of the net import on a site with over 30 metres of level variation.

That same approach applies to any scheme where earthworks drive the cost. Getting the levels right on the model first is far cheaper than moving material twice.
