In May 2017 VolkerGround Engineering completed a £0.75m contract for Marcus Worthington Group, to undertake Continuous Flight Auger (CFA) piling and steel sheet piling works. These works were to enable the development of 280 apartments at Newcastle’s Stephenson Quarter.
The development was separated into three blocks with varying piling platform levels. We utilised a PVE-55R CFA rig to drill 600mm diameter piles to a maximum depth of 31.5m.
We were able to provide a collaborative, problem solving approach to issues that arose on site. The client’s existing retaining wall collapsed due to heavy rain. VolkerGround Engineering developed a solution to install a temporary sacrificial sheet pile wall so works could proceed without major disruption. This required the team to pre-auger the pile line first, because of stiff clays at depth, prior to installing the sheets.
This solution meant the team worked from behind the installed sheets and from a lower level, ensuring that no additional load was put on the unsupported ground.
We value engineered an additional retaining wall offering a sheet piled wall rather than a contiguous bored pile wall, which provided commercial and programme savings to the client.
This project required logistical expertise and collaborative synergy from VolkerGround Engineering.
Director for VolkerGround Engineering, Brandon Ferreira said: “In recognition of the significant programme delivery and cost savings, Worthington have awarded VolkerGround Engineering the piling contract for their flagship development in central Manchester. We look forward to a continued relationship with this prestigious North West based company.”
