Part 4 – Case Example: Bangkok MRT ProjectsKey Points:• Building Services• Some access-related issues for M&E works remain incomplete and need to be addressed once the M&E project begins.• System designs, such as the TVS, are not fully aligned across all contracts prior to M&E contract access.• Architectural Works• These issues occur mainly in M&E-only contracts, as they do not fully accommodate operational requirements or the M&E contractor’s needs.• Trackwork• The extension phase must be compatible with the existing line to ensure smooth through• All third rail gaps must be inspected to ensure compatibility with the rolling stock.• M&E-only contracts may not fully meet operational needs.Part 5Discussion
Part 5 – DiscussionSummarise key messages from earlier parts:• M&E is the backbone of railway system safety, reliability, and operation.• Lifecycle thinking (EN50126) ensures consistent quality from concept • Subsystem integration is critical — requires continuous interface coordination.• Bangkok case studies show gradual localisation and stronger project governance.• Knowledge sharing supports sustainability and local expertise growth.Part 5 – Discussion
