Metro, rail and tunnels
Linear projects with hundreds of interfaces.
Metro projects are run by joint ventures with several designers, systems contractors and an Engineer for each package. Documents must follow the interface matrix, and every change has to be traced across stations and tunnels.
Our team delivered electrical works for four tunnel boring machines on 16 km of the Riyadh Metro, and brings that interface discipline to every document.
What we prepare
- TBM and tunnel power method statements
- Station MEP submittals
- Interface letters with systems contractors
- Temporary works and ventilation submittals
- Joint venture correspondence registers
- Programme updates by section
