Lower Marsh Street

London

VolkerGround Engineering was awarded a £50,000 contract by Deconstruct UK Ltd to design and build a sacrificial retaining wall for a basement development on Lower Marsh Street, London.

The team installed 35 linear metres of sheet piling with a 5m retained height using a Movax SP 500KN vibratory hammer, handled by a 25-tonne excavator.

The willingness of the client to accept vibratory installation within a central London site enabled the design to be refined as penetrating the clay, which is generally required when pressing, was not necessary.

VolkerGround Engineering carried out soil loosening to aid drivability and minimise noise.

This offered both cost and programme savings, even when taking into account the proximity of Network Rail’s head office and the fact that the VolkerGround Engineering team had to reduce working hours during lunch periods to minimise disruption to Network Rail.

Nonetheless, the works were completed in a quick and safe manner.
