Going underground with Dublin Metro

LBA Dublin Metro

Generating key connections in the Irish capital, LBA was pivotal in the planning of the Dublin Metro, an all new, city-wide transport plan.

The Dublin Metro North will be a high capacity light rail system connecting the outer northern suburbs to the city centre. It will connect a number of key destinations including Dublin Airport, universities, hospitals and retail centres.

Integrated Transport System

The scheme is being developed by the Rail Procurement Agency (RPA) as part of the Irish Government’s Transport 21 development plan and will provide a fully integrated transport system, linking with existing heavy rail and tram stations, creating new interchanges.

Segregated Light Railway

The scheme includes a fully segregated light railway with both surface running sections and underground sections constructed in cut and cover and bored tunnels. There are 17 new stops along a route length of approximately 18km. There are two sections of bored tunnel, approximately 5.5km in the city centre and 2.4km at the airport. There are 6 city centre stops constructed in deep underground structures and a new deep stop at the airport.

The Railway Order planning enquiry is being held in 2009 and 2010 and Public Private Partnership tenders are being procured.

Specialist Technical Support

London Bridge Associates (LBA) have provided specialist technical support on the project since 2006 on the scheme definition, reference design and planning submission stages for the technical designer, Jacobs, and more recently the RPA directly.

Project design and planning management

During the development of the reference design and Railway Order documentation, LBA provided project management, design management and coordination, construction planning and concept design work within the integrated team This included design of tunnels and shaft structures, coordination of structural design work and architectural services, and overseeing traffic management requirements. Construction planning input was provided into the scheme design and planning.

Detailed Design Work

LBA provided the Project Manager and engineering supervisory staff overseeing the extensive ground investigation programme carried out for the project.

LBA in working directly for the RPA have provided project management and technical support for the Railway Order Inquiry and design coordination for the detailed design of the Mater Hospital stop that is to be constructed in advance of the main works.
