Organizational and technological modeling as applied to the processes of reconstruction of buildings of higher education institutions is based on the division of models into structural and functional components - a model of the spatial and technological structure and a functional model of the process of reconstruction of a building of higher education institutions. The article discusses the organization of the work site with the technological sequence of the flow of work processes. Taking this into account, graphs of works were compiled by stages, showing the possibility of parallel production of works, as well as showing the necessary work preceding them. Based on this, a conclusion was made about the effectiveness of the application of the methodology of organizational and technical modeling to increase organizational efficiency.

With information modeling of buildings, the time and money spent on creating a building project is significantly minimized, and it also becomes possible to make changes to the project, reducing the likelihood of a designer making a mistake. However, building information models have a number of disadvantages expressed at each stage of the object's life cycle. In this article, the main stages of the life cycle of a building were highlighted, according to regulatory documents. The drawbacks of using information models at each stage are highlighted and their influence on the work in the information modeling environment is considered. Ways to minimize these shortcomings, taking into account the prevalence of BIM-models of the building at the present time, are proposed. The general problems of transition from the classical design method to information models are highlighted.

Technical progress makes humanity create new technologies and methods in all spheres of life. Evaluation of property also in there. In current moment there are several methods, which are badly obsolete. For example, there are some cases, when building in decrepit or emergency condition were able to buy in cost several times higher than objective cost. These cases aren't unique. New method of evaluation of property could possibly help if not to stop in all appearing of this cases but less their amount. New method is based on Building Information Model (BIM). This model allow take all needed information about building in the currnet moment of time and see in dynamic, how change different indicators of building. This system can be more useful if it associates some amount of building, which differs indicators of interest building and reflecting effects of that building on themselves. This technology can be looked as Extented BIM. Consideration of implementing BIM in evaluation of property has very perspective vay - this can accelerate the time building can be evaluated, and also it let potential client to see all information about building which he need. This makes process of purchase-sale of property more clear, which, by turn, help avoid conflicts when property being researched before purchasing.
