Large residential development in Whetstone, London
Site inspection showing the progress of the ground works for this extension in London.
The site is being excavated with a digger, the depth of the footings need to factor in the impact of an Oak tree that is located within 6m of the nearest footing. At this distance, according to NHBC standards the stability of the soil requires us to excavate 3m below the base of the tree. Due to the natural slope of the site (property is located on a hill) the effective depth of the footing can be achieved with a 2m dig, as the slab level is set 1m below the base of the tree.
In order to preserve the roots of the tree and also to implement cost efficiencies in the formation of the footings, the foundation adopts a pad and beam design, to minimise costs.
The building control inspector has visited the site today and confirmed the depth of the footings and condition of the soil is acceptable. The site is now ready for the concrete pour.
