Measurements of Horizontal and Vertical Movements of Buildings, Embankments and Infrastructure

Because of a methodology of construction and/or surface or even rock instability some buildings must be monitored during construction, what means vertical movements between new building and surroundings objects must be measured during the constructions.

The goal of geodetic (elevation) measurements is to identify possible vertical movements of a building, which could cause serious damage on a building itself. Vertical deformations are calculated from measurement’s results, acquired in at least two different time periods.

Terrain elevations are obtained by surveying techniques that determine vertical differences between points among vertical control networks. Our experts are specialized for following methods:

• differential leveling with I. and II. level of accuracy with precise digital level Leica DNA03 (0.3 mm standard deviation per km double leveling)
• trigonometric leveling (exceptionally for I. level of accuracy) with electronic total station Leica TC1800.

In both cases we declare enough supernumerary field observations needful for mathematical adjustments of geodetic network, what is the basis for evaluation of elevation accuracy which enables further evaluation of vertical movements

Network adjustments are generated by software VIMWIN. Movements measured between two time periods are generated with software PREMIKWIN1 with capability of statistical evaluation of particular movement regarded to its accuracy. If there is an interest we can present results in appropriate graphical forms, most often with some kinds of iso-lines.
