The construction of Dublin’s ambitious MetroLink project will require approximately 8,000 workers, with the majority needing to be recruited from abroad, officials revealed at a parliamentary transport committee hearing.
Project director Sean Sweeney told the committee that no Irish companies possess the facilities and expertise required for such a massive undertaking. Consequently, all major contracts will be awarded to international firms, which will bring workers from overseas during the construction period.
Accommodation Challenge
Sweeney acknowledged that finding accommodation and facilities for the incoming workforce presents a significant challenge. He confirmed that the MetroLink team has been in discussions with the Land Development Agency to address housing needs for the international workers.
Full Re-Costing Underway
A comprehensive re-costing of the project will be published early next year, Sweeney explained. The original cost estimate of €9.5 billion was based on data from the 2014-2019 period and was updated in 2022. However, that figure is now considered inadequate and does not reflect significant inflation in the construction industry.
The revised tender designs will only be completed next month, meaning the re-costing will be based on previous MetroLink designs. An independent pricing firm will examine the updated figures to provide accurate cost estimates.
Sweeney, a New Zealander who previously served as CEO of Auckland’s City Rail Link underground rail project set to open in 2026, was appointed program director in June of last year.
Project Timeline and Costs
Transport Infrastructure Ireland chief executive Lorcan O’Connor told the committee that the project cost needs revision to account for inflation, new requirements and other commitments. Once the review is completed and verified, it will be submitted to the government.
O’Connor expressed hope that the metro could open by the mid-2030s.
Dublin’s Game-Changing Project
Dublin’s long-awaited MetroLink made a major breakthrough last month when it was finally granted planning permission after years of delays.
The approximately 19-kilometer rail line, mostly underground, will connect Swords to Charlemont near St Stephen’s Green and extend from the airport to Sandyford. Current estimates place the project cost at around €11 billion.
The project features 16 proposed stations and will use fully automated trains running every three minutes, officials said. The government is preparing to establish a special “MetroLink Delivery Body” and invite tenders for building contracts in 2026, though experts suggest actual construction may not begin until 2027 or 2028.
While no official opening date has been announced, government officials and construction experts are describing the MetroLink as a “game changer” that will dramatically reduce traffic congestion in Dublin and provide faster connections between homes and workplaces along the corridor.
The project represents the single largest public transport investment in Irish history and is seen as critical infrastructure for accommodating Dublin’s growing population and reducing the capital’s reliance on private vehicles.
