How do you find the verticality of a high rise building?

The plumb bob is the most commonly used tool for monitoring the verticality of a building under construction. Two plumb bobs at at the end of each face of a building, Extending up to a fixed height from the base of the tower, so that same reference points are used at all time, can give the best result.

Keeping this in consideration, how do you measure the verticality of a building?

The procedure used to check column verticality includes: 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.

Likewise, how do you check the alignment of a column? We usually take a plumb bob to check the alignment( in this case verticality of the column).
