I've finally worked out how much we charge per m2. Normally I quote by day for 1 man.
Block paving:
72m2 per day + 4 bags of sand @ £7 x 4 = £28 + 2 hours sanding
Sand: @ £7 x 4 = £28 ÷ 72 = 0.40 per m2.
Labour: £400 ÷ 72 = £5.50 per m2.
Re-sand labour: 2 hours + 1 hour traveling = £150 ÷ 72 = 2.08 per m2.
Total: £7.98 per m2
Everything else:
72m2 per day £400 ÷ 72 = £5.50 per m2.
I seems very expensive what we charge, it would be good to know what others charge as a bench mark.
