Highway Engineering

SIAC/ Ferrovial (Northroute JV)

Ireland

This 13.5km Dual Carriageway scheme forms a vital link in the main Dublin-Belfast corridor.

The €100m project, through difficult topography involves the design and construction of 13.5km of all-purpose 2-lane dual carriageway, three grade separated junctions, 11 principal structures (road, river and rail bridges), soft and contaminated ground geotechnical solutions and the realignment of approximately 6km of associated regional and county road.

As sole Contractor’s Designer, RPS was fully responsible for conceptual design, value engineering, detailed design & specification, traffic management design, landscape design, construction supervision, certification of design and construction.

Limerick County Council & National Roads Authority

Ireland

The 675m tunnel under the River Shannon is one of the largest and most complex infrastructural projects ever undertaken in Mid-West Ireland.

RPS, in a joint venture with COWI, were Project Consultant/ Client Representative since 1999 and has worked with its JV partner, Limerick County Council and the National Roads Authority (NRA) on delivering this key piece of infrastructure that forms a critical link in the Government’s proposed Atlantic Corridor running along the western transport spine of the country.

Prior to 2004, RPS led and project managed the JV team for the route selection, preliminary design and Environmental Impact Statement (EIS) phases leading to the granting of permission by the national planning board, An Bord Pleanála. Since 2004, RPS has been responsible for providing technical advice and assistance to the NRA for the tender phase and provided technical advice, design review and contract monitoring services during the construction phase of the project.

Galway County Council and the National Roads Authority

Ireland

The M6 Galway to Ballinasloe PPP scheme was the first inter-city motorway to be completed in Ireland.

RPS worked with the National Roads Authority and local authorities since 1999 to deliver the impressive project which opened six months ahead of schedule in December 2009.

The €750m scheme consists of 56km of dual carriageway from Galway to East Ballinasloe along with a 7km link road to Loughrea and 32km of other side and link roads. It includes over 30 road bridges including five grade separated junctions, three rail crossings, one 100m river crossing and one footbridge crossing. RPS provided consultancy services on the initial route selection and environmental matters, and preparing the CPO, EIS and preliminary design; then carrying out the design, procurement and supervising substantial advance contracts. RPS also implemented environmental monitoring and mitigation measures for the project and conducted the detailed design review stage, as well as assisting with technical aspects of the PPP procurement process.

Transport Infrastructure Ireland

16.5km of motorway in County Wicklow and major urban interchange in Dublin delivered on budget and ahead of programme.

RPS is Transport Infrastructure Ireland’s Representative on this €282m PPP project since 2009. The project includes the M11 Rathnew to Arklow motorway which opened in July 2015, the N7 Newlands Cross Junction Upgrade which opened in November 2014 and a motorway service area on the Gorey Bypass due to open shortly.

The M11 project was completed seven weeks ahead of programme and will reduce journey times by between 10 and 20 minutes, depending on traffic conditions. It comprises 16.5km of toll-free 2 lane motorway, two grade separated junctions, eight bridges, realignment of sections of the old N11 and link roads to tie into the existing road network.

Newlands Cross grade separated free flow junction on the N7 Dublin/Cork road has replaced the last signal-controlled junction between the Northern Ireland border and the Dunkettle roundabout in Cork. The N7 at this location carries approximately 90,000 people daily and the junction upgrade, with three lanes in each direction, will reduce journey times.

The flyover element has a two-span bridge structure with extensive embankments on the east and west sides of the junction. The materials used for the embankments were all sourced locally and environmentally friendly cement was used to reduce CO2 emissions. The Newlands Cross Flyover was awarded the Irish Concrete Society Award for Infrastructure in April 2017.

Lagan / Ferrovial JV

Ireland

RPS was appointed Designer by Lagan Ferrovial JV on the Northern Ireland DBFO project, which involved the design and construction of 12km of dual carriageway in Northern Ireland between Cloghogue Roundabout south of Newry and Beech Hill, north of Newry.

The project connects to the A1 / N1 scheme, also designed by RPS, at Cloghogue. The scheme includes the design of four grade separated junctions, soft ground geotechnical solutions, the realignment of 15km of associated side roads, three river bridges, one rail bridge, eight road overbridges, three underbridges and two accommodation works bridges.

Titanic Quarter Ltd

Northern Ireland

The new Titanic Signature Building is a centerpiece and key catalyst in the regeneration of Belfast's Titanic Quarter, and the economic recovery of Northern Ireland.

RPS was commissioned to provide civil, structural and fire engineering services in relation to the project. As a phase of the overall Titanic Quarter project, the Titanic Signature Building links together key Titanic heritage sites on Queen’s Island in the Belfast Docklands.

RPS was involved in the detailed design of the site civil engineering infrastructure works which included ground decontamination. These works are essential components in the development of the site and they have been designed to accommodate the future development that is anticipated to take place. These works include new roads, signalised junctions, upgrading of the existing carriageways adjacent to the site and public realm areas along with the site drainage infrastructure.
