LUAS Line B1-400

  • Lead contractor’s designer for this light rail scheme under an RPA FIDIC D&B contract. 
  • Systems engineering approach through the design to the completion of the works on site. 
  • Bespoke and innovative solutions to civil design.

The LUAS Line B1 project involved a 7.5 km light rail extension to the south of Dublin. 

The project consists of 12 stops over a combination of semi-urban and green field settings. There are over ground and ‘at-grade' sections with four associated sub-stations for power requirements.

Started on May 2007, the project was opened to passengers on October 2010.

Seamless transition

Strong design management was a key feature throughout the project, with the Arup project management team providing a constant and pro-active support to the contractor and RPA.

Arup also provided systems integration support, allowing for a seamless transition from an existing light rail system, to an extended light rail system. An interface management was employed to highlight all inter-related and inter-disciplinary connections, which reduced the risk of conflicts in the construction phase. 

The Arup site supervision role included the management of all physical integration issues between the different design supervision teams.

The project achieved complete integration and interface design management and the optimisation of operational safety and design through visibility assessments and performance studies.

Arup was also responsible for the systems integration, the migration of the central control system and associated systems as well as Line B1 and Line C1 extensions to new platforms.
