Piling and foundations specialist Roger Bullivant has installed a series of continuous flight auger (CFA) piles in the central reservation of the A1(M) near Newcastle to support new stanchions for two existing footbridges. The work was carried out close to Washington motorway services in December 2004 to ensure bridge columns comply with current vehicle impact standards.

Bullivant installed eight CFA piles in the central reservation to support two new uprights on each bridge.

A further 14 supporting piles were installed beneath each walkway beside the southbound carriageway.

The 600mm diameter CFA piles were installed to depths of between 7m and 14m, depending on the location of coal seams traversing the site.

Bullivant carried out the work for Castle Construction on behalf of the Highways Agency.
