I've just put together my first quote for a SUDS compliant driveway since the new 'legislation' came in. The client is a really nice bloke and I'm already doing the landscaping he wants in the back garden.
I've explained about the implications and risks of compliance/non-compliance (such as I understand them) and told him that I will only build a compliant drive. I've worked out my costs for a 'normal' drive and the additional price for putting in 12no. Wavin Aquacell traffic in membrane in a 4 x 3 array at 700mm depth from the invert to the surface. Wavin technical help did the calculation. The subgrade is excellent; free draining and firm with little or no clay. The water will be collected in a 5m linear drain at the kerb to the pavement.
My normal method of pricing (including a couple of steps and some kerbs, recess tray, etc.) comes out at a little under £5000, roughly £75/m, which has been par for the course recently.
The price for the collection and snazzy soakaway comes out at £1800! The crates are list @ £86/ea but I've got a price from my bm of £40/ea which still seems like a lot for a fancy beer crate. I've then got an additional skip/small grab plus the acco, drain pipes and couplings, geotextile membrane, sharp sand, shingle, etc., plus the labour to dig out, install, back fill and prepare ready for the driveway sub-base.
What do you think?
