IRELAND: Transport Infrastructure Ireland has launched the tendering process for the M500 contract to design, build, finance, operate and maintain the planned MetroLink automated metro line. It will run 18.8 km through Dublin from Swords in the north to Charlemont in the south.
TII said this is a significant milestone, marking the progression from planning into procurement and delivery.
‘The launch of this procurement process for this contract represents a clear signal of our ambition to deliver world-class, sustainable transport infrastructure’, said Minister for Transport Darragh O’Brien on May 1. ‘This government is committed to delivering MetroLink with quality, value for money and long-term public benefit at its core.’
Contact scope
The M500 contract covers the trains, signalling for GoA4 unattended automatic option, the depot and maintenance facility, a park-and-ride facility, the control centre, trackwork, electrification, power and communication systems, mechanical and electrical systems including tunnel and station ventilation, internal walls and secondary civil and building works within the shell and core structures of the underground stations, the fit-out of 16 stations above and below ground and urban realm enhancements.
TII also proposes to award an early services agreement to the preferred tenderer. The M500 contract does not include enabling or major infrastructure works, including tunnelling, for the mostly underground line, as these are being procured separately.
TII CEO Lorcan O’Connor said the M500 contract ‘has been carefully structured to allocate risk appropriately, encourage innovation and ensure long-term operational excellence.’
The contract would allow seven years for completion of the works followed by 25 years of operation and maintenance. It will be structured as an availability-based public-private partnership contract, with the contractor paid for making MetroLink available and functioning to a high standard for the agreed time period. TII said this approach spreads the cost over many years, transfers construction and maintenance risk to the contractor and encourages long-term service quality.
Procurement process
The procurement process will commence with a pre-qualification stage to assess a bidder’s capability, experience and capacity to deliver.
It is anticipated that the three highest-ranked eligible applicants for the contract will be shortlisted and selected to proceed to the next stage of the competition.
The estimated value in the contract notice is €7.3bn+VAT in net present value terms; however TII notes that EU procurement rules require the contracting authority to indicate an estimated value, but the February 2026 estimate is not binding and actual tender prices may be higher or lower.
National Transport Authority CEO Anne Shaw said, ‘through this procurement, we welcome ambitious and experienced partners to be part of a once‑in‑a‑generation transport project and to play a vital, long‑term role in designing, building, operating and maintaining a system that will reshape mobility across Dublin and beyond.’
