1. Civil-Systems Interface Management

- Combined 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 Systems
- E&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 transparent 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 Integration
- Interface 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 Compliance
- Ensuring 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.
