Zenit Probor – Modern equipment for controlling the status of formwork
Analysis of observations by plumbing shows that along with an average random error of ± 8 to ± 30 mm of observation, the plumbing is given a systematically lowered result due to the fact that the plumb line is placed at the points of the operating floor that do not receive the highest displacement relative to the design position. Systematic underestimation of formwork deviations ranges from 0 to 30 mm.
Consequently, the anti-aircraft industry, compared with plumbs or theodolites, ensures significantly more accurate results of control over the position of formwork. When using the anti-aircraft type, the complexity of work and the time spent on measurements are sharply reduced.
