GMP were approached to undertake the design and installation of the Continuous Flight Auger (CFA) piles for the office block development on Cranwood Street in the outskirts of central London. The site was in-between two roads which ran parallel to each other with a level difference of approximately 2.00m. The piling platform was circa 14.00m x 20.00m. Due to the basement requirements of the development, the piling platform was 3.50m below the existing ground level of the site access. Due to the continual communication between GMP and the Contractor, an effective ramp was constructed for the GMP rig. The mobilisation of the piling plant and equipment ran smoothly, and without disruption of the surrounding area – critical in this busy part of London.
The 40 No. piles were 600mm in diameter, ranging between 18.00m & 23.00m deep, depending on their vertical capacity requirements. All piles were founded within stiff London Clay at depth. Although site logistics were a challenge, plans were put in place and communication between all involved made sure that the project was completed safely and two days ahead of the Contractors required programme.
