INTERFACE COORDINATION FRAMEWORK FOR OCC BUILDINGS IN METRO RAIL

Metro rail projects involve complex coordination between civil, electrical,
signaling, and telecommunications systems. The Operations Control
Center (OCC) building acts as the operational hub of the metro network
and therefore contains a large number of engineering interfaces. Lack of
clearly defined responsibilities and improper construction sequencing often
leads to coordination failures, schedule delays, and cost overruns. This
Chapter presents a structured methodology for developing an Interface
Responsibility Matrix (IRM) and evaluating the impact of construction
sequence on OCC building coordination in metro rail projects. The
proposed approach identifies interface owners, defines responsibility
boundaries, and integrates sequencing analysis with interface
management. A sample IRM structure and sequencing framework are
presented to demonstrate how coordination can be improved during
construction and system integration phases.
