- Each well designed project, related to digital modelling for the needs of assessment of conditions of an engineering structure, contains comparison of results of numerical calculations with results of surveying, Usually, results of levelling, which determine differences of elevation of controlled points of the structure, are the subject of such comparison. Results of measurements of a horizontal network may be presented in a similar way. In the course of comparison, functional, structural and accuracy differences of digital models, as well as models based on results of surveying monitorine should be also considered. Comparison of modelling results with results of surveys may be performed for various purposes. Besides the diagnosis of current conditions of the structure, emergency or non-standard situations, such comparison may be performed for specific demands of geodetic services, and, in particular, the needs of modernisation of the geodetic control oetwork or in the process of the initial control of surveys. Such comparison may be performed in order to asses the digital model, developed basing on archive geological reconnaissance and/or verification of values of parameters of materials. The paper discusses the demands of verification of digital analysis by means of back analysis, as well as possibilities to utilise the results of geodetic monitoring for the needs of calculations. It should be noticed that the geodetic control network should be consulted with designers of the particular structure and with the entity which performed numerical analyses. Those issues are illustrated by means of the example of development of the control network and the numerical model for a building, which is jocated in the densely built-up area, within the direct neighbourhood of the Warsaw underground.
