2 Determining the Building Line A building square is positioned against the rear of the kerb, beyond the corner mark indicated on the kerb.The dimension is then taken from the back edge of the kerb keeping the tape running parallel with the builders square.A wooden peg is then driven into the ground and the exact dimension is marked by a nail in the top of the peg.Corner of building marked on kerbXEnd of tape against back edge of kerbX
3 Determining the Building Line Positioning peg Z can be done in the same way as peg X making sure that it is positioned beyond the length of the building.ZX
4 Determining the Building Line Once pegs X and Z have been positioned a Ranging line is fastened to the two nails in the pegs. The ranging line needs to be pulled taut between the pegs as this indicates the Building Line.ZX
5 Establishing the corner of the building. A line is then extended along the edge of thebuilders square and beyond the building linewhere the two lines intersect determines the frontcorner of the building.ZBuilder's square positionedagainst kerb and aligningwith the corner of thebuilding mark on the kerb.X
6 Establishing the corner of the building. A peg (A) is driven in at the intersection of the lines anda nail in the top of the peg identifies the exactposition of the intersection.This denotes the front corner of the building.ZAXA
7 Establishing the width of the building ZThe dimension for the width of the buildingis measured from the nail in the top of peg A.Peg B is driven in at the required measurement.The exact measurement is identified by a nail inthe top of the peg B.BAXNote. For accuracy keepthe tape taut.
8 Setting out a right angle (corner of the building). YZBAPositioning Peg YA builders square is positioned against thebuilding line and lined up with the nail in thetop of peg A a line is then pulled out to peg Ythe line is to run parallel with the square creatinga right angle.Peg Y is positioned beyond the required measurement of the building.X
9 An alternative method of setting out a right angle is to use the 9004m3m
10 Identifying the dimension for the side of the building ZCBAA measurement is then taken to identify the width of the building a peg (C) is then driven in the exact measurement is then identified by a nail in the top of the peg.When peg C is positioned pegs X, Y and Z can be removed.X
11 Identifying the position of the final corner BCheck the dimensions of the side of the building ( A-C).Transfer the measurement to the other side to (B-D) Drive in a temporary peg.A
12 Identifying the position of the final corner BCheck the dimensions of the front of the building(A-B) then transfer the measurement to the rearthis allows peg D to be positioned a nail can then be put in at the required measurements.A
13 All four corners of the building are now positioned
14 Checking the diagonals BMeasure and note the diagonal measurement(A-D). Now measure diagonals (B-C) and checkagainst the (A-D) measurement.If the dimensions match this indicates that thecorners are at right angles and the building issquare.A
15 Checking the diagonals If one of the diagonals is longerthan the other, the back two pegpositions (C-D) will to be adjusted.Note large adjustments may requireadditional pegs to be located adjacent to pegs (C-D).BA
16 Checking the diagonals Small adjustments can be made by moving the nail/screw in the top of the peg.Move nails/screws by the same amount, in the same direction, to maintain the overallDimension.
17 Checking the diagonals Correct setting out willindicated by identicaldiagonal dimensions.Check all dimensions arecorrect.All surplus pegs are removed,leaving the four corner pegsindicating the building position.BA
18 Building PositionFour corner pegs indicating the buildingposition.
19 Profile Boards Foundation Walling Overall widths of foundation trenches andwalls are identified onprofiles.The pegs are positioned on the inside of the profile board cross pieces. This prevents the line tension pulling the cross piece from the pegs.
20 Profile Boards Partly driven nails in the top of the cross piece Identify the wall and trench marks. But as an alternative to this saw cuts can be made into the cross piece.
21 Position of Corner Profiles Profiles should be positionedapproximately 1.500m minimumaway from the edge of the trench.The distance may need to be increased if a mechanical excavator is to be used for the excavation.1.500MinThe cross pieces shouldbe kept level.Future Foundation Excavation
22 Profile Boards Once the profiles are set the ranging line needs to be extended from the corner pegs and marked on to the profile.
