Oak Tree on Building

[swinny]

can you not do something similar to this thread?

That was the other option. The only problem I can forsee is the anchoring of the top for when it is freed off the building. The root plate is still semi attached to the floor but only in the direction of the lean. Working from a MEWP would make the job a safer proposition than being on the stem when its tethered. The tree is 3 feet diameter at the base and then split into 3. Two limbs we've removed already its the main central one that remains. This is this is a good two feet diameter and where on the roof is down to three stems at about 8-10 inches each.

 

I suppose the worse that could happen if the tether was to not be as good as it should would be it would end up hung a bit lower down the building. This would probably cause less damage than winching the trunk off in one. I'll probably make a final call when its been stripped of all its branches from the upper crown.

guy the tree to a ground anchor (possibly from one of the main branches which are now pointing "up") situated in line with, and several meters behind, the stem? then release from roof using mewp, and release tension on the ground anchor while winching/ pulling the stem away from the building with a second line.

 

just an idea although i have never done anything like that before!!

[detritus21]

There is another tree not far behind the tree in question which could be used as a likely anchor point. My worry will be regarding rope breaking strains and the weight of the tree.

i'd remove as much weight as possible before tensioning the guy line, but yea i see your point you'l still be left with a hefty bit of wood!

 

i've got some 4 ton polyprop you could borrow?

it simply isnt resonable to drill or picus all trees, and its only due to very wet soggy ground and extremem weather/wind that these recent ones have occured.

 

but could the use of using thermal imaging not be practable to all tree surveys? where a picus can take hours, and core sampling imo old skool and invasive, and both only offer a specific view of the inside of a tree in the specified survey point, the thermal imaging takes minuites, highlighting potential demons in the whole tree.

i think thermal imaging could be deemed reasonable . . .

I liked it 'Urban camouflage' covers up those horrible flats. Looks like it's going to be a mare of a job to get it down tho.

[detritus21]

It may be a mare of a job but it should be well worth it

 

My biggest issue is the main trunk. Its coming down one way or another. I've been told extra damage won't matter but I'd prefer it to be fairly neat (the building that is)

when a tree like this is sat on a building it is usualy stable enough to clean off all none supporting materials, preferably cutting out hefty props as you go, three being ideal one for the wieght downward, and one at each angle to stop side ways movementand possible in this instance, the props are added to support the trunk as tightly as possible supported on a ring/cord if on grass to stop them pushing in.

 

once all free material AND its wieght has been relieved as much as possible if it hasnt lifted at all it is then a case of slowly methodicaly making back cuts on the supports till it is sat on the props, thenm bobs your uncle, fannies your aunt and its chogs away.

 

that is if YOUVE GOT TO, and have no MEWP, BOBCAT, CRANE etc etc

Am finishing it next week. Its in a secure position at present. Mewp to strip it out and close to edge of roof and then its sever the butt end from the root plate and winch it off like a hung up tree.

 

 

You could end up with a few more windows on that side of the building!

 

If your going to do that I wouldnt bother with the MEWP and just try to winch it off sideways with a gob in the base, maybe.
