Developer St George West London is transforming the Old Kings Mall car park in Glenthorne Road into 418 luxury one, two and three-bed apartments in a multi-storey complex called Sovereign Court. The site includes a two-storey basement excavated by JGL and with the help of Groundforce Equipment, we were able to support the secant-piled retaining wall during the process.
The hydraulic props were installed at ground floor level to support the RC capping beam and due to the shape of the excavation, most of the 17Nr. hydraulic props were not perpendicular to the capping beam and special steel brackets were cast into beam to accommodate the angels.
The props are all high capacity units, mostly MP250s with a load capacity of 250T. Unually - and due to the very long spans involved, most of the propers were combined with 1.20m dia. 'super-tubes'. These large-dia. tubes (twice the standard dia.) provide the necessary section modulus to prevent any risk of deflection over the long spans.
