Just got a copy of Spons Landscape pricebook 2024. Thought people might be interested in the following:
Spons prices include 15% contractor profit. That £7 per m3 makes a hectare at .25 deep £17,500.
That tallies pretty well I reckon with the Rory's initial estimate of two weeks for two men with digger and dumper (£1k/day?) to do a hectare at 100mm deep.
If a hectare at 100mm deep takes ten days at £1k a day, that's ten grand. Doing it to 250mm deep will be about double. Obviously
@JD450A estimated the 1ha initially allowing for the ballache of working on a conservation site. So 20k per ha is 3.5k more than the Spons ballpark price.
