Subject: moving trees query


Dear All,
I have a case here where there are 12 L.Plane trees along the
centre of a car
park. They are approx. 20ft tall and stem diameter of 8" - 10".
They are
planted in a two - three foot wide grass strip, edged with kerb
stones and then 
tarmaced beyond.
The client wished to put together a footbridge in the car park
using 80 tonne 
22m long pieces of steel girder.
Given their planting location, I am not sure if a tree spade is
feasible, and
am looking for ideas on how to dig them up and move them? or, give
up on them 
completely and ask for money to replant new elsewhere?

any thoughts gratefully received.

Bettina

Hi
Moving with a tree spade isn't an easy option because of the size of
planting bed.
For a 70cm girth tree (9" dm), you really need a 2m tree spade for
peace of mind.
You could only manage an 85cm spade there, recommended for trees up
to 20cm girth.
For the sake of academic interest, the 2m spade would cost around 7.5
K pounds (2.5k per day at 3 days min hire).
It would certainly be a cheaper option than replanting, if it could
be safely executed.
You may find bargain trees in Holland, but you will still need
someone to plant and guarantee them for you?
A typical UK price for 60-70 cm girth plane would be 1.5-2.0k to
buy, free delivery on 12, planting with warrantee at 30% of supply
and a second year warranty for another 30%, plus watering costs, say
50 man hours at 10 pounds/hr. 

If we assume 1.5k for supplying 12 then the maths is as follows:
12(1,500 + 500 + 500 + 500) = 12 x 3,000 = 36,000 (5 times more than
the tree spade value)
You would be better off (less head ache), using this sum as the basis
for compensation and planting smaller (up to say 30-35cm girth stock
in the hundreds of pounds ball park), unless it's a really
prestigious site?
NB 36 K is the cost of replacement, not the actual (CTLA or other)
value of the trees. These would need to be depreciated to reflect
condition, location, suitability etc. to the effect that they may
only be worth say 75% of their replacement cost. Indeed, they may
have 0% of that value and be worthless, if they are in the way of
approved development. 

Regards

Adam
