STRATEGIC INTERFACE RESPONSIBILITY PLANNING FOR
SEAMLESS EXECUTION OF UNDERGROUND METRO
PROJECTS

Abstract:
Underground metro rail projects involve complex construction environments
where multiple contractors, engineering disciplines, and system packages operate
simultaneously. Effective interface management is therefore essential to ensure
seamless coordination among civil, architectural, mechanical, electrical, and
system works. This study presents a strategic framework for Interface
Responsibility Planning (IRP) to improve coordination and reduce construction
conflicts in underground metro infrastructure projects. The research analyses the
interface management practices implemented in the Chennai Metro Rail Phase-II
project, focusing on tools such as the Interface Management Plan (IMP), Interface
Coordination Sheets (ICS), Master Interface Matrix (MIM), and BIM-based
coordination models. These tools help define responsibilities, track dependencies,
and monitor interface risks throughout the project lifecycle. The proposed
approach integrates BIM-based coordination with interface responsibility
allocation to improve communication among stakeholders and minimize clashes
during construction. The results indicate that systematic interface responsibility
planning significantly enhances construction efficiency, reduces rework, and
ensures timely project execution. The framework can serve as a practical guideline
for managing complex interfaces in large-scale underground metro infrastructure
projects.
