Setting up profiles on site (Step by step)

  • Set up first peg on site.
  • Measure 7.2m with tape. (8.2m: Start 1m from tape for accuracy)
  • Place peg two.
  • Measure 15.5m from peg two. (16.5m)
  • Place peg three.
  • Measure 7.2m from peg three. (8.2m)
  • Place peg four.
  • Measure 15.5m from peg four to peg one. (16.5m)

  • Place three pegs per corner.
  • Measure 1m from pegs one, two etc...
  • Form a three-point 90 degree angle with profiles.
  • Set up dumpy
  • Adjust bubble to center.
  • Use 8m tape measuse to find mark 110mm for concrete level (FFL).
  • From (FFL) 110mm mark, use tape measure.
  • Find horizontal line via dumpy on tape measure.
  • Use the same measurement for all profiles i.e (931mm).
  • Mark the FFL
  • Set up batter boards and bracing for profiles.
  • Set up string line for the first two profiles.
  • Square up all four profiles with string line.
  • Use 3,4,5 technique to confirm measurements/squaring of site.
  • Confirm measurements of 7.2m, 15.5m and diagonal 17.091m. 
  • Replace the four house site pegs to the final measurements from the string lines.
  • Site is ready to be boxed for concrete.
