Indicators of Directive Change Consequences in Construction Projects

The article presents a methodological framework for formalizing and quantitatively assessing the consequences of directive changes in investment and construction projects. The relevance of the study stems from the absence of regulatory and methodological tools that objectively measure the impact of client-issued directives on project schedules and resource networks. The aim of the research is to develop a system of formalized indicators that capture calendar, network, and resource consequences of directive interventions. The methodology is based on the classification of directive changes through six attributes (Stage, Source, Scale, Form, RI, CI) and the development of three interrelated metrics: ΔT (schedule shift), CP-Impact (critical path influence), and OZ (resource overload zone). The proposed formulas and structure enable integration into digital project environments such as PMIS and BIM. The results establish a methodological basis for further predictive modeling of delays and evaluation of phase vulnerability across the project lifecycle. The scientific novelty lies in introducing a formalized system of quantitative indicators for directive change consequences, bridging an existing institutional and digital gap in project management. The practical value consists in the potential use of these metrics for analytical monitoring and improving time and resource controllability in complex construction projects.
