Cost of core drilling?

[Alan Ambrose]

Anyone have some ballpark costs for core drilling? In particular, some 150mm holes for MVHR ducts through a 365mm RC wall?

The ones that do site  work charge £30-40 per 159 hole

I had 3 x 180mm holes drilled, about the same length. IIRC it was about £250.

Whatever size you think you need drilled add 10mm, then foam the gaps after fitting the pipe. Don't ask why I know.

For a small number you might be best paying a day rate. 5 holes (from 63mm up to 200mm) half a day, two guys was £250.

Those all sound very reasonable given the kit and skill involved.
