  Take the reading of the steel tape through the telescope. Take the readings of two positions at the same level on both top and bottom levels of the formwork. By taking two readings at the same level any curvature on the surface can be identified.

    Thank you for your time. The probleme here is the reading at the TOP how did i get to the TOP to take my reading?

    I have the same idea is to take two shot on the column one shot at the Bottom and another at the Top at each shot i will take the Vertical Angle and the Slope Distance

    So I will have two rectangles triangle to solve and Calcs two Horizontal Distance (DH) that I will compare. If  DH1 = DH2 at +/- 3mm this mean the column is vertical...

      Solving those triangles for distance will tell you if the column is vertical in only ONE direction, forward and away from the robot. To check the vertical, left and right, you need to sight the vertical crosshair on one side of the column and turn direct and reverse horizontal angles down low and then up high.If all 4 angles are equal then the column is vertical, left and right, from the robot.
