The client鈥檚 team is led by Turner & Townsend and WSP, supported by O鈥機onnor Sutton Cronin, Mace and PwC.
The firms have been appointed to a framework that will be in place for the duration of the design, procurement and construction phase as the project client seeks to nail down costs on the project.
Running for 18.8km, much of it underground, MetroLink will be a high capacity, high frequency metro railway with 16 new stations running from Swords to the north of Dubline to Charlemont in the south.

MetroLink project director Aidan Foley said: 鈥淲e believe the terms of engagement through the NEC4 professional services contract represents a real opportunity to work collaboratively and productively towards achieving our shared project goals. We are looking forward to working closely with our new colleagues to advance the project through the next stage of its development.鈥澛犅
Turner & Townsend has acted as commercial advisor on the programme since 2018. Its infrastructure lead, Gary Easton, said: 鈥淢ajor programmes like MetroLink offer a once-in-a-generation opportunity to transform the way people travel across the capital, connecting communities both inside and outside Dublin with an efficient, low carbon public transport service鈥β By closely engaging and collaborating as one team, we will be fully realising this project鈥檚 goals with as minimal disruption to the public and local business as possible.鈥
The public accounts committee of D谩il 脡ireann, the lower house of the Republic of Ireland鈥檚 parliament, expressed concern in a report last month about the wide range of cost estimates for Metrolink. It said: 鈥淭he most likely cost for the construction of the Metrolink system was estimated at 鈧9.5bn 聽by the Department [of Transport] in April 2023, with the most credible capital cost ranging from 鈧7.16bn to 鈧12.25bn, although some estimates for the project allow for a cost as high as 鈧21.5bn.
