Good morning Temeraire

Your first post here, so welcome to the Forums.

If you are going to get helpful responses, I think you need to provide a bit more explanation as to what issues are concerning you. 

In broad terms access problems for groundworkers on housebuilding and other construction sites is usually about things like uneven, soft etc surfaces and getting down into excavations and back out, whilst at the same time not being crushed by moving plant or coming into proximity ontact with overhead, underground and other "services". So whether an individual house has reached the stage of putting in a DPC perhaps not a stage in the process where conditions suddenly change that much. 

However, it seems obvious that some particular aspect is concerning you. What is it?

Hi Temeraire

Let's assume for a moment that the brickwork is all 800mm high at this point in the construction programme. Some workers would attempt to climb or jump over the brickwork - do-able but risky. But usually there would be a doorway, and that would provide much easier access. 

What might be needed for the internal drainage inside the building would be measures to provide a relatively level surface (before e.g. a ground slab is poured) Some boarding?

Would it be possible to set up a single access point for each plot and then simple install a stoned up ramp either side of the sub-structure masonry?

Hi Temeraire

I think you might be overthinking this a bit, as the issues you raise in terms of handrails and "scaffolding" apply whatever the nature of the "working platform" as defined in the Work at Height Regulations.

So, the sensible suggestion of a stoned up ramp falls within the WAH Regs definition of "working platform" but I doubt that anyone is thinking about detailed engineering calculations so as to comply with Schedule 3 of the Regs. 

Hence, depending on the potential fall distance from that stonee up ramp, it might be reasonably practicable to decide that it needs a handrail on one side or both though perhaps not. Technically by reference to British Standards you would want that handrail to be able to withstand a point loading of 0.89kN which in layperson's terms rquates to about two thirds of a not atypical construction worker's weight at 1100mm above the surface on which they are standing. Are they really going to do calculations or erect something based on what they know to work and then give it a good shove to check that it DOES work. Then your "inspection" regime is to check that it remains sturdy! Actually a bit easier using scaffolding components than bits of timber as scaffolders are taught what works.

So, perhaps approach this from a position of pragmatism ahead of fancy engineering?
