Profile boards: set them once, trust them all job.
Profile boards (sight rails) hold your lines and levels long after the pegs have gone. But if they're flimsy, too close to the dig or not checked, they can move without anyone noticing.
Getting profiles right on Greater Manchester jobs:
• Set them well back from the excavation so they don't get knocked
• Brace the posts properly so the boards can't twist or sag
• Mark each board clearly: which line, what offset, what it's for
• Check the lines between boards against your control before footings go in
Stockport to Bolton, Salford to Oldham, a solid set of profiles saves a lot of re-marking later.
Do you still use profile boards on your jobs, or have you gone over to pegs and paint?
