demolishing a chimney and doing some fairly major bathroom
alterations. This is all formally priced up and contracted
through the parent firm. Whist they are here I have
thought it would be really handy if they could use the tools they
already have been using for the main job in the bathroom
alterations (ie a big core drill) to drill me a suitable hole for
a tumble dryer exhaust. This is undoubtedly "out of scope"
so I was hoping to offer one of them a few drinking
vouchers to do a bit of overtime for me. If I have to DIY
I will have to buy or hire kit or "chain drill" the hole.
Can anybody suggest a sum that would be reasonable for this job as a
"little extra" for someone who is already on site with all of the
right kit? It is on the first floor so if it cant all be done from
inside work will have to be done from a ladder.
Thanks in advance for any pointers.

What size of hole?

110 shurely?

117 of course.




Id or od?

I should say that the o.d. of a hole in a wall is, at best, undefined.
