Works out 170 euro per day per man, not sure lad to be honest. What does a chippie charge per day now 200-250 euro per day.
There is a hell of a lot of work involved.
Do u provide the Senco screws if they are using screw guns for the plasterboard, they are dear feckers per box. If not then I suppose for the amount of work it is decent money, but take 2 weeks for 5 men, hard to know, the euro per day rates seems ok, the fact it will take them 2 weeks I may question.
The slab the ceilings, if I am correct in thinking that it is ONLY ceilings and not dormers or walls, I would say that it would take probably take 3 days for 5 men who are used to slabbing, say very max 4 days.
The insulation of rafters and roof pitch again 2 days with 5 men should fly it.
Thats 5/6 days.
What exacltly are they doing with the EXT walls? Is it cavity?
