Spanish-based engineering firm IDOM are providing design services for the MetroLink.
The project includes 19 km of new metro from Estuary north of Dublin Airport to Charlemont south of the city centre.
It will involve the construction of 16 stations and contains a significant length of tunnel.
The project will also offer connectivity to Dublin Airport, Irish Rail, DART and Luas services.
A preferred route was launched in March - which will see the MetroLink run from Swords to Charlemont, and not Sandyford as originally suggested.
During the original consultation process, the National Transport Authority (NTA) and Transport Infrastructure Ireland (TII) said "issues came to light" and the revised route "addresses the concerns raised."
Among the major changes, construction in the Mobhi Road area no longer required the acquisition of a pitch belonging to Na Fianna.
A second significant change was the arrangement around Charlemont.
The route published last year included a proposal to upgrade the Luas Green Line to Metro standard.
It is projected that the number of people seeking to travel on the Green Line in future years will exceed the capacity of the Luas system, requiring an upgrade.
But the new plan has said that upgrade is not expected to be needed for some time - perhaps 20 years or so.
The NTA and TII held five public consultation events between April 8th and April 16th.
They expect to apply to An Bord Pleanála for planning permission in 2020.
The construction phase is set to begin in 2021.
