Hello All
Apologies if this question has already been asked and answered elsewhere in the forum; a brief search didn't reveal anything.
Background:
I'm planning to install a new driveway across a field: the drive will be about 160m long x 3m wide, with a parking/turning area at the end. Total area about 800 sq. m. The route for the drive is generally level (perhaps a gradual slope down between entrance and turning area), with some undulations. Location: Derbyshire.
The installation of the drive will enable renovation/building work on a building at the end of the drive. After the building work is complete, the finished surface will be applied to the drive. The intention is to use a self-binding gravel for the finished surface (e.g. Breedon but without the Breedon price tag!). The recommendation for that seems to be 50mm compacted depth.
The sub-base will be 150mm compacted depth (compaction using a vibrating roller as described on the PE site - but don't know weight of roller yet to determine no. of passes ...).
So the plan is to dig out at least 200mm deep, apply a layer of Terram 1000, install the sub-base (Type 1) and use that during the building work. Spoil from digging out will be distributed around the field - there are plenty of large hollows that can be filled.
After all that the question is, I hope, simple: approximately how much per sq. m could I expect to pay to have a sub-base installed as described above by a competent contractor (excluding cost of Type 1)? Assume no spoil removal necessary.
I realise that's probably impossible to answer this question properly without seeing the site. However, any ballpark figures based on experience are greatly appreciated.
Thanks in advance!
