London: St Johns Wood King Post Wall
Challenge
DAWSON-WAM was contracted by Brennan B&CE and Bouygues UK to design and construct a king post retaining wall for a new education facility in North London. The steeply sloping boundary of the site was formed of generally stiff clays that got stiffer with depth.
Solution
The king post wall consisted of steel column sections installed within a 450mm diameter concrete pile. Piles were installed using DAWSON-WAM’s Cased CFA to depths of up to 11m.
Result
Fabrication of corners and junctions to the king posts was completed off-site to minimise on site hot works and precast concrete panels were manufactured off site to exact dimensions to avoid cutting on site.
