“…The basic element of geodesy is the acquisition of spatial data of the earth's surface and objects with the help of various geodetic measurement techniques and instruments. The applicability of non-contact methods for determining displacements and deformations is described in [1][2][3][4][5]. In addition, the analysis of various geodetic methods is carried out to determine displacements and their applicability and suitability for detecting displacements of smaller values.…”

Determining the displacements and consequent deformations of structures is a demanding branch of engineering. Displacements are most often determined by geodetic methods, among which high-precision non-contact methods have recently taken the lead. Engineering geodesy is an indispensable part of construction projects. In the desire for efficient and fast measurements, the technology of terrestrial laser scanning (TLS) and the use of robotic total station (RTS) and other geodetic methods are becoming more and more useful for engineers. In the presented study, we focused on the measurement and comparison of vertical displacements with various mentioned equipment and the determination of the influence of meteorological conditions on the displacements of timber beams that we used to perform the experiment. Measurements were performed both in the laboratory and outdoors. A novelty in the work was the use of a TLS scanner to determine the evaluation of small value displacements and the analysis of the usability of geodetic measuring equipment. In the Materials and Methods section, we describe the equipment used and the characteristics of the beams. The Results section describes the experimental outcomes, which include the performance of experimental analysis of vertical displacements of timber beams under different meteorological conditions. Altogether, the results consist of geodetic measurements and the processing of measured data. The results of measurements of vertical displacements with a terrestrial laser scanner were compared with the results obtained with a robotic total station were evaluated and compared with the displacements calculated from static analysis and the results of other methods used.

“…Traditionally, great size constructions are monitored through techniques and high precision and accuracy geodetic equipment, including precision levels, total stations, laser scanner and photogrammetric equipment (Mills and Barber, 2004) (Costantino and Angelini, 2014) (Sabuncu and Ozener, 2014) (Beshr, 2015) (Capra et al, 2015) (Mill et al, 2015) (Lienhart, 2017) (Lienhart et al, 2017) (Kovačič and Motoh, 2019). More recently, these techniques have been implemented with the use of satellite positioning, GNSS technology (Global Navigation Satellite System) (Acosta et al, 2018).…”

“…On a smaller scale, more specifically of elements which make up a structure (beams, columns, foundations, slabs etc. ), monitoring has been carried out by employing structural instrumentation techniques with the use of deformation sensors, displacement transducers, accelerometers, inclinometers, extensometers, etc., (Erol, 2010) (Detchev et al, 2011) (Díaz et al, 2018) (Kovačič and Motoh, 2019).…”

Monitoring and control of large size civil works was an important and well known application area for topographical and geodetic methods, with a wide range of articles published. However, documented experiences applying precision geodetic methods in monitoring in a smaller scale (structural elements: beams, columns, slabs, etc.) are sparse. The main objective of this study is to evaluate and compare the use of precision geometric levelling technique with instrumentation with displacement transducers (structural instrumentation method) in vertical displacement control in a concrete beam with excessive deformation, being subjected to recovery processes and reinforcement. Although precision geometric levelling is not considered a modern technique in the structures monitoring, it is cost-effective feasible, accurate, and highly precise, with acceptable uncertainties and results, considering procedures normally followed in the processes of recovery and reinforcement related to this type of works. The results have shown that precision geometric levelling is an effective alternative, with remarkable advantages in assembling times and installation, as well as in monitoring post-recovery process of structures (medium and long term), and as the possibility of establishing a correlation between the behaviour of the monitored points. In addition, precision geometric levelling is a valid alternative to be implemented jointly with structural instrumentation techniques, especially where redundancy needs to be obtained in the observations.
