This document discusses several types of setting out works including: 1. Setting out a foundation plan using a center line plan and batter boards. Batter boards are used to accurately transfer the center line onto the work site. 2. Setting out a sewer line by fixing stakes along the proposed center line and excavating the trench to the desired width and depth. Cross heads and sight rails are also used to maintain proper gradient and alignment. 3. Setting out a culvert involves marking points along the center lines X1 and Y1 based on given distances from the origin point O. Pegs are placed at the intersection of the points using two tapes held at equal distances between assistants. The culvert is then set

- 7. Setting out Sewer Procedure Fix stakes on the ground at the centre line of the proposed sewer at 20m intervals. Set out a parallel line to the proposed centre line of the sewer on one side at a distance apart so that it may not get disturbed during excavation. Excavate the sewer trench of desired width and depth Erect cross heads at 30 m apart and each change of gradient and direction. Set the top edge of each sight rail truly horizontal with the help of a spirit level. Drive in a nail on the top edge at the centre of the sight rail to define the centre line of the sewer.

Now along OY, points 1’,2’,3’ and 4’ are marked at distances y1,y2,y3 and y4 from O. Now two tapes are taken with their zero ends together and held at P1 by the overseer in such a way that when two assistants hold them fully stretched at 1 and 1’, the readings are exactly equal to y1 and x1 (i.e. P1 1 = y1 and P1 1’ = x1). Then the point P1 is marked with a stout peg. Similarly the other pegs are fixed at P1,P2,P3 and P4. The pegs for the right half are fixed according to the data available from the table prepared for the left half. The culvert is symmetrically about
