I volunteer as a Gardener for a charity locally.
I have been asked to plan and cost up materials required to construct a concrete hardstanding for a 7.5 tonne wood chip delivery lorry to use when delivering wood chip for a boiler system. It visits every ten days or so, arrives and spends some 15 minutes standing whilst delivering the wood chip.
The area that needs to be concreted is 3.5 meters wide by 9.25 meters long. The assumptions I have made for estimating purposes are:
1. we need 150mm of MOT compacted as a base using a standard whacker plate.
2. we need to use steel mesh to strengthen the concrete
3. we need a 150mm layer of ready-mix concrete strength C20 and a 25mm slump laid on top of the MOT.
It would be great if my assumptions above could be confirmed or corrected as appropriate.
Also should the concrete pad be laid as one mass or should it be a series of 3.5m by 3m slabs?
I have laid domestic drives and slabbed paths before with no issues of collapse or subsidence. However, I have not had to tackle anything of this scale before.
