Abstract: Building Information Modeling is the concept of a digital presentation of the physical and functional properties of an object. This paper presents proposal of use of terrestrial laser scanning technology to complement and verify created three-dimensional models of objects. The issue of the article focuses on the technical aspects of data collection from terrestrial laser scanning and its use in the information system of the building. During the field work authors carried out an experimental measurements of office space by phase laser scanner Z+F Imager 5006h. These data were treated as experimental material to test common methods of calculating the transformation parameters of three-dimensional systems, which are used in the calibration of individual scans and fitting them into the given coordinate system. This step is have a significant effect on the accuracy of the spatial model. The measurement experiment confirmed the need for calibration point clouds based on the largest possible number of tie and enabled to propose an inventory technology of long and slender buildings. It uses the connection between terrestrial laser scanning and conventional tacheometric measurements. This solution will reduce errors transferred to another position in the construction of the traverse. The article also deals with problems related to inventory of architectural and construction aspects of buildings and vectorization integrated point cloud in order to develop plans for the buildings or the measurement of specific surface areas. Creation of the models, on the basis of spatial point cloud built from the line of discontinuity is difficult due to: the impact of calibration errors, causing the displacement between cans and blur single scan points belonging to the same surface. Based on the performed studies it was found that the most important advantage of terrestrial laser scanning is possibility to collect in a short time a large number of points representing the actual state of the object, not the design intent. Using laser scanning we can significantly reduce the time spent directly at site, and perform measurement in dark areas. This technology also has a particular application for creating BIM for the modern buildings with complex geometric form, for which the accuracy and timeliness of the created model can be crucial for cost, speed and ease of execution of  individual works. In this paper authors will attempt to assess the effectiveness of the application of the presented technology for building information modeling.
