The open-source software attracts the engineering society with the accessibility, the chasing of processes, the flexibility and the possibility of making changes to the interface or in the program code processes. This paper presents the results of a comparative review of several groups of open-source software (OSS) for modelling and analysis of constructions. The advantages and challenges of working with OSS in comparison to the use of widespread products with commercial licenses are analyzed. Software products of two categories are considered: (a) geometrically/graphically modelling/drawing of the structures - 2D, 3D CAD; (b) calculation and analysis of building structures under different load conditions and geometry including geotechnical problems. The software products selected for the purpose of the report are compared based on the performance of a simple engineering task from practice. The sufficiency of the results, the options for presenting the data and other additional characteristics of the products are commented.
