Abstract
Effective collaboration between the client, contractor, and engineer is a crucial element in the successful completion of a construction project. This article analyzes the key aspects influencing the coordination of project participants, including organizational, economic, and communicative factors. The study examines theoretical models, illustrating the impact of communication quality, financial transparency, and adherence to contractual obligations on the implementation of construction projects. Examples of successful project management practices are analyzed, along with common challenges that hinder effective interaction among stakeholders. Based on the identified patterns, recommendations are formulated to optimize processes and reduce the risk of conflicts.
