Rock & Alluvium has successfully completed the piling works for a new mixed use development on the site of the Janet Adegoke Leisure Centre in London’s White City.
Work at the site included bored piles and a 350m long secant piled retaining wall to allow a 4m excavation to be completed. To counter lateral forces generated by the dig, each hard mix pile on the secant wall had a large 11m long steel reinforcement cage installed within it. The wall will also support the load of the new building – in some cases up to 900kN – so the piles were up to 19m in length. Over 800 secant piles were installed each with a pile diameter of 600mm.
In addition, a reinforced concrete guide wall was built to ensure the secant wall achieved required constructional tolerances.
The work was completed in less than seven weeks using two 55t Soilmec CM70 piling rigs.
Sister company Galliford Try Partnerships in now working on the main structures that will provide health and social care in the area along with 170 new private and affordable housing units plus retail, office and cafe space.
