flanagaj Posted 9 hours ago Author Posted 9 hours ago I wasted a weekend and a £100 in timber .. the surveyor chap marked it all out in 2 hours 🙄

Mr Punter Posted 8 hours ago Posted 8 hours ago If you can, transfer the survey markings to just outside the building footprint so you can easily run a string line down the centre of the trenches and re-mark. 2

I think you said the site is sloping. The tapes need to be tight and horizontal. if necessary use a spirit level to bring one point op to the level of the other. Then don't panic if it is a few mm different. the diagonals exaggerate any differences and you have more opportunities for precision as you come out of the ground.

Would you still check even though it was set out with a total station? some of the pins are not vertical, so that will skew the diagonal measurement.

Russell griffiths Posted 2 hours ago Posted 2 hours ago Now you have your pins in place you could set up your profile boards if you want, you can mark external wall and internal then see it all drops onto the foundation. are you going 600 wide or 700. im sure something changed recently regarding regs.

Yes I would, because people make mistakes. Presumably the pins are in the ground at the exact spot, so you measure to that, or to a spirit level up from it. Also check any critical distances, for example to an existing feature or a boundary. I would also do as I said earlier and take references, but it is up to you. This is in case a pin is knocked over. It is simple to place offset pins or pegs. Project the wall lines you have, and put a mark in 1m (typically) beyond, at each end. If using a peg, put a nail in the top. You then have 8 pegs. If you wish , tie an orange stringline between them and you have your rectangle, increased by 1m. Then the digging can all be within that, and you have an immediate check. you may also be saving a visit or 2 from the total station.
