(vi) Pass a cord around the perimeter of joint as well as wing wails as 1, 2, 3, 4, 5, 6, 7, 8 and mark the overview of the foundation with lime and by nicking i. e. cutting a narrow trench along this line. (vii) Similarly fix the corners Click This Link of other abutment and also wing wall surfaces and also note the synopsis of the foundation (setting out survey).

Indicators on Setting Out Engineer You Need To Know

(ix) The catchment area. (x) The maximum rate and also discharge at the bridge site. (xi) The detail and also outcomes of trial pits and also borings etc. The length of the bridge is needed to be determined along the centre line. If the bridge is short, the length may be measured directly with a steel tape however that of a big bridge is gauged by technique of triangulation.
