Nick,

No literature I'm afraid just some suggestions:

I'd suggest considering using a tree radar for locating the roots or trial

holes using an air pick. You may find there is nothing substantial in the

way.

Then its a case of considering the temporary protection to the ground to

spread the load of the piling rig, the shearing forces and vibrations on

roots that are in the way, leakage of contaminants and how you're going to

fit the piling rig in beneath the crown.

I should think a lot is going to depend on soil type. If you was on clay

do you think the glazing that might occur as a pile or auger went in would

glaze the pile hole wall enough to stop contaminants leaking laterally?

Here's an interesting piling site

Afraid not Ron, this is for a substantial lighting structure at a

sporting

facility. The tower is some 50m in height with a 6 ton lighting unit on

the

top. It is a substantial engineering project. The detailed design is

still

ongoing however I am lead to believe that it will consist of 6-8no. 450mm
piles of around 20m depth. They are all to be placed in the RPA of 2 no.
TPO'd Lime trees. Space is at a real premium and relocation is not an
option.

Does anyone know where I may find guidance regarding piling in proximity
to trees?
