BIM-TECHNOLOGIES FOR MONITORING AND DYNAMIC ADJUSTMENT OF THE IMPLEMENTATION OF THE CONSTRUCTION CALENDAR PLAN

Statement of the problem. The subject of the research is information models of a complete life project in the sector of architecture, design, construction and operation of buildings and structures. The purpose of the study is to build a model that implements the forecasting of the progress of the calendar plan and optimizes management decisions aimed at minimizing the negative consequences of external stochastic impacts. Results. An information model of construction based on a vector description of basic structures and hierarchical construction of derived structures is constructed. All model structures are divided into static and dynamic components. Based on the information model, optimal algorithms for monitoring the implementation of the calendar plan and optimizing management decisions in the conditions of external stochastic influences are formulated. Dynamic indexes are obtained that allow optimizing both strategic and operational management decisions. The optimal monitoring frequency in terms of the cost/return ratio has been determined. The software implementation of the algorithms proposed in the work in the shell of the relational database management system has been performed. Conclusions. The results of the study allow us to conclude that in the conditions of external stochastic impacts, information technologies significantly simplify the dynamic monitoring of the implementation of the construction schedule and the development of management decisions. The introduction of a vector description of the information model of the full life cycle into the practice of the construction industry makes it possible to optimize both local models and mechanisms of interaction between project participants.
