Dealing with concreted cavities

[Shane]

I went to look at a large and poorly oak yesterday.

 

Its between 6 and 7 ft diameter at the base and has, over the years shed 5 or 6 large limbs (up to 3ft diameter). All the cavities I could see have been filled with concrete.

 

About 30 years ago a bungalow was built 20 ft from the tree (in the direction the prevailing wind would take the tree).

 

The customer had a report from an AA consultant last year who recommended its removal, and the LA TO has agreed it can go, or be majorly reduced.

 

The customer wanted various prices -

Reduce massively to about 25 ft (to limit poss damage to bungalow)

 

Remove completely

 

Reduce to 15 ft monolith, or as low as poss above the concrete.

 

I can price up various options excluding the concrete issues but wondered what others do/say when concreted cavities of an unknown depth are involved - for the full removal option.

 

There is absolutely no chance of vehicle or crane access.

The bottom 15 ft looks like its riddled with concrete and I don't fancy knacking up a load of 48 inch chains.

 

The customer can't tell me any more about the concrete as it was done before he moved in.

 

Any suggestions?

Price the chains into your quote.

Use a concrete chainsaw?

The only thing I can think of is get a good sized drill bit and drill a few test holes I know the trees a size but what elsa can you do.

Can't help you but...I watched one of these being used a few days back, quite impressed.

Yea but thats never ending . You could replace chains all day and get no whare if you constantly are in concrete . Got to use a disk cutter with a stone disk .

[Will Heal]

Give them a sensible price for the reduction and monolith and then a crazy high price for complete removal. They are unlikely to go for the fell then but if they do your quids in. No chance of getting a mini digger in with a corkscrew splitter on it and just split it standing? Now that I want to see!

Could run an IS flag up on it then give the USAF a ring.
