Job Description

1. Civil-Systems Interface ManagementCombined Services Drawings (CSD): Coordinating the creation of drawings that show all systems (piping, ducting, cabling) in a single view to ensure they do not physically collide in the limited space of an underground station or tunnel.Structural Requirements: Ensuring the Civil team provides necessary openings (cut-outs), sleeves, and foundations for electrical panels, transformers, and signaling equipment.Space Management: Managing the allocation of space in the "Technical Rooms" and tunnel walkways for various contractors.2. Technical Coordination for SystemsE&M (Electrical & Mechanical): Coordinating the integration of tunnel ventilation systems (TVS) and environmental control systems (ECS) with the tunnel structure.TPS (Traction Power Supply): Managing the interface for Overhead Equipment (OHE) or Third Rail mountings and the grounding/earthing systems throughout the underground stretch.Signaling & Telecomm: Ensuring that signal equipment and antennae locations have a clear line of sight and are protected from electromagnetic interference (EMI).SCADA: Overseeing the integration of remote monitoring systems that connect all mechanical and electrical assets to the central control center.3. Operational IntegrationInterface Control Documents (ICD): Developing and maintaining the ICDs, which are formal agreements between two contractors (e.g., Tunneling vs. Signaling) regarding who provides what at the boundary point.Conflict Resolution: Leading meetings to resolve technical disputes when one system's requirements (like a large fire pipe) block another's (like a cable tray).Testing & Commissioning: Coordinating "Integrated Testing" to ensure that when a fire alarm goes off (Systems), the fans start (E&M) and the trains stop at the correct location (Signaling).4. Safety & Standards ComplianceEnsuring that all interface designs comply with international metro safety standards (like EN 50126 for RAMS).Verifying that fire-stopping measures are implemented at all points where cables or pipes cross between different fire compartments in the underground station.
