The article is dedicated to explaining how communication efficiency in construction project networks forms through interaction-driven structural change. Relevance emerges from the growing mismatch between rigid coordination models and the fluid nature of communication in distributed project environments. Scientific novelty is associated with interpreting communication networks as adaptive systems in which efficiency depends on internal transformation rather than static structure. The work describes how interaction parameters reshape network configurations and how these configurations alter coordination regimes. Special attention is paid to threshold conditions under which communication patterns reorganize. The work sets a goal to explain the mechanisms linking interaction rules with structural outcomes. Analytical synthesis, comparative examination, and conceptual modeling are used to address this problem. A set of recent studies and empirical configurations has been examined to identify recurring patterns of interaction and transformation. The conclusion describes how communication efficiency depends on structural adaptability and alignment between interaction conditions and network configuration. The article will be useful for researchers and practitioners working with complex coordination systems.
