I’ve got a 4m2 (porch) and 16m2 timber framed extension that I am planning. I want to pay fine one else to do the ground works up to dpc, what sort of ball park should I be looking at? I know a lot depends on spec etc, but I would appreciate a rough guess from those in the know. 
thanks

Help us to help yourself.

Clearing the area. What is there now?

How accessible is it.?

 

Clear site and  prepare. 2 days?

Dig trenches. 1 day?

Pour concrete 1 day

Block or brick walls 2 days.

Stone base 1 day 

Concrete slab 1 day

Clear up and leave. 1 day

1 day float 

 

Does that sound right?

 

10 days x 2 men at £250  = £5k.

Materials about £4k

Add 20% for overheads 

 

About £11k

Add 20% vat.

13k

 

More if tricky access, biggish firm ,  anything you havent  mentioned, drains, insulation if required,  London or SE.

Thanks. The first is a porch, only 2x2. Ground is currently a concrete path for the first meter, then gravel. You can get to the whole thing with a mini digger. 
 

Second is 4x4, currently a conservatory with a suspended floor and patio area. Again, full access with a digger.
