MetroLink’s eSourcing Portal
MetroLink is excited to announce the launch of its new eSourcing portal, designed to make the procurement process simpler, faster, and more efficient for suppliers. This portal will now serve as the central hub for all direct procurement activities with MetroLink, including access to and submission of Pre-Qualification Questionnaires (PQQs) and Invitations to Tender (ITTs).
What does this mean for suppliers?
To participate in upcoming procurement opportunities directly with MetroLink (as a Tier 1 or main contracted supplier), suppliers must register on the MetroLink eSourcing portal. The registration process is quick and easy, taking around 10 minutes to complete. We strongly encourage suppliers to register as soon as possible to ensure they are ready for future opportunities.
What about eTenders and the Opportunity Portal?
In line with legal requirements, Prior Information Notices (PIN), Contract Notices and Contract Award Notices will continue to be published via eTenders.
The Opportunity Portal will be launched during the Spring of 2026 and will sit alongside the MetroLink eSourcing portal. It will provide transparency of subcontracting opportunities in the MetroLink supply chain.

M100 Enabling Works
Transport Infrastructure Ireland (TII) launched a Periodic Information Notice (PIN) on 19th May 2025 for the MetroLink Enabling Works programme.
The Enabling Works are designed to clear a path for the main infrastructure works contracts. This approach will ensure that the site areas are free from risks such as existing utilities, archaeology, heritage items (for storage/ replacement) and buildings currently occupying station locations etc. to the largest extent possible.
The programme of Enabling Works comprises the establishment of a suite of framework agreements and qualification systems to facilitate the procurement of enabling works which will commence in advance of the main infrastructure works contracts (civil engineering, tunnelling and stations).
To deliver the Enabling and Advance Works for MetroLink, TII intends to establish a series of Contracts, Frameworks and Qualifications Systems.
The M100 packaging strategy is detailed below.
Expected Timeframe
The updated procurement programme for M100 contracts is now available, please see the revised timelines and milestones below.
Call-off contracts are currently being developed for each of these frameworks and qualification systems and will be procured as scheduled throughout the lifetime of the MetroLink Programme
The Enabling Works programme is being procured via procedures which will encompass the issue of a Contract Notice and the issue of pre-qualification documents for the frameworks. The qualification system for Archaeology is now live and can access the Contract Notice via eTenders.
