There are two different methods used for tower verticality determination: using Global Navigation Satellite Systems (GNSS) observations; three-dimensional terrestrial geodetic measurements using total station or traditional geodetic measurements methods. Conducting regular verticality inspections for thin tower structures is essential for ensuring structural safety, extending service life, and optimizing operation and maintenance strategies. However, the traditional theodolite inspection method, as a commonly used technique for verticality. Structural Standards for antennas and their supporting structures are outlined in ANSI/TIA-222. NWTE also evaluates other structures used for communications such as water towers, building rooftops, concrete poles, wood/timber poles and steel monopoles. Two plumb INTRODUCTION The process for inspection of Tower Verticality, Tilt at leg sections, and deflections at any elevation by comparing to the position of the Tower legs at the base is. Report of First Pilot audit of Transmission Tower by the audit team of the committee constituted for audit of transmission towers with respect to design and the life of the towers (on a 5% sampling basis).
