Test piling for Simplex on the M40

Simplex Foundations is installing preliminary test piles and working bearing piles for the construction of a new road bridge spanning the M40 Motorway as part of the M40 J15 bypass currently underway in Warwickshire.

The works on the Highways Agency job, with Morrison the main contractor, included installation and testing of 750mm and 1050mm rotary bored piles in a contract valued at around £360,000.

Orientation of piling rig and cranes was planned on a pile by pile basis to allow continuation of the main contractor’s programme and a safe working radius.

Ground conditions, variable between the north and south abutments, are generally made ground over sands and gravels, over Mercia mudstone. 

All piles are founded with specific penetrations into mudstone and tested to 1.5x safe working load.
