A contract worth €2.5m for a 'concept architect' who will work on Dublin's MetroLink project has been advertised.
In a clear sign that the project is moving ahead, Transport Infrastructure Ireland (TII) is seeking submissions from architects who want to work on the development for nine years.
The MetroLink will be a north-south urban railway service that will run between Swords and Charlemont, linking Dublin Airport, Irish Rail, Dart, Dublin Bus and Luas Services.
In their notice TII said it will create "fully integrated public transport along the 19km route".
There will be a total of 15 new stations, 3,000 extra park and ride spaces and a journey time of approximately 25 minutes from Swords to the city centre.
It is intended that construction work will begin in 2021 and the first passengers will be on board in 2027.
The final cost of the project is still in dispute, with initial estimates of €3bn now believed to be at the lower end of what is likely.
The €2.5m figure for an architectural company is an estimate based on "assumptions, notional hours and information to hand".
"TII does not commit to any amount, any retainer and all projects are subject to approval," the tender notice states. It adds that price is not the only award criterion.
The architect will be responsible for applying "value management techniques" to ensure value for money from public funds "without reducing service quality".
A key requirement of this role is to work with the engineering designer in ensuring that the developed concept design and architectural vision is consistently followed throughout the project from preliminary design stage through to project completion.
They will provide advice on station construction methodologies to ensure designs are developed with an integrated approach and integrity of concept design is retained.
The successful applicant will also be in charge of reviewing designs for cycling facilities as well as new and existing routes.
TII said: "Tenderers should note service duration is for nine years, or for the period including the planning and consultation, construction and testing of the system leading up to the operation of MetroLink."
