Abstract
<jats:p>The article considers methods of combining when performing works and problems with their organization in construction, analyzes the current status of the prevalence of these methods in the construction industry of the Russian Federation. The uncertainty and risk reduction options in processes of parallel execution of works are considered. As part of the study, a systematic analysis of existing methods to improve the system for reducing the duration of construction of housing projects was carried out. Focused on identifying points of potential life cycle reduction by running work in parallel at different stages. Four methodological groups are considered: traditional methods of calendar-network planning (CPM, PERT), methods of optimization of irregular flows (CPM-LOB, Delta-shift, matrix and graphical approaches), information modeling technology (TIM) as a tool for data integration and collaboration, and hybrid models that combine the elements of these approaches. For each of the groups, advantages and disadvantages have been identified and systematized, conditions for their effective application have been defined, as well as limitations that arise when implementing the principle of parallel execution of work. Based on the comparative analysis, it is found that the greatest synergistic effect in reducing the duration of the investment-construction cycle is achieved when integrating critical chain methods, The organization and technologies of information modeling in the framework of adaptive hybrid models of life cycle management of capital construction objects. The results of the study can be used to inform the choice of organizational and technological solutions aimed at reducing construction time and improving resource efficiency.</jats:p>
