There are 4 no 220mm Bottom Driven Steel Cased Piles , with a 450x450mm ground beam spanning between then, Claymaster and Cellcore have been fitted to the ground beam to resist heave. Pile Rebar is 1No Full Length H16, Concrete is RC35, Casing Spec is BS10218/5235. A set of 5mm was reached on site. No Slip Sleeves were installed.
NO SI has been done, UK Post code is CM16 4PT Easting, 546205, Northing 201855
Top 4 meter of ground was wet clay, foreman who as installed the site has said the foundation is good.
The ground has been described to have a high plasticity soft clay and there are trees nearby,
We need calculations to prove that the piles have sufficient anchorage to resist the effects of heave, due to changes in water movement in the year and also if the trees were removed
Calculations to be done to British Standards or Euro Code
P1 - Load - 59kN Factored - Length - 3.5m
P2 - Load - 109kN Factored - Length - 4m
P3 - Load - 129kN Factored - Length - 4m
P4 - Load - 92kN Factored - Length - 4m
"Can you please explain to me how a pile that is only 3 metres deep regardless of whether it is a driven steel pile or a cast in situ bored pile is able to resist the upward forces created by clay heave" This is a query from the client engineer so the calcs need to satisfy this."
"engineer has not addressed the issue of the potential damaging effects arising from the vertical forces caused by the clay heave that would develop following the removal of all or indeed some of the trees, most notably the large tree in the front garden and the row of cypress trees along the boundary line.
I would be grateful therefore if you would please confirm that should any or all of these trees be removed for whatever reason, then your foundations will not be disturbed as a result." This also needs to be addressed
