Civil Engineering

RPS has a track record of working closely with a range of clients including Public Sector Highway & Drainage Authorities, Private Developers and Contractors to deliver sustainable schemes which meet the needs of all stakeholders.

Our teams have expertise across wide ranging business sectors including: airports, highways and transport interchanges, manufacturing & distribution, food, rail depots, waste & renewable energies, education & housing, retail, leisure & mixed-use.

The services offered by RPS to these clients include:

Planning

Environmental impact

Building architecture

Civil Engineering design

Structural Engineering design

Mechanical and electrical services design

Highway design

Coastal engineering and modelling

River and estuary engineering

Our civil and structural engineering teams work closely and collaborate with other team members and other disciplines whether within RPS or separately appointed by the client to provide design solutions that are fully coordinated.

Typically, these teams will be required to provide input to a project at the following stages:

Masterplanning

Environmental impact assessments

Transport Assessments

Preliminary design

Detailed design

Value engineering

Design support during construction

Construction supervision

Our engineers have a pro-active design philosophy giving careful consideration to economics, health and safety and the environmental impact of the design solution and we use the latest design techniques such as Building Information Modeling.

A1 / N1 Newry to Dundalk Design Build

A1 / N1 Newry to Dundalk Design Build

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.

Corrib Onshore Gas Pipeline

Corrib Onshore Gas Pipeline

Shell E&P Ireland Ltd. (SEPIL)

RPS provided a range of detailed engineering services in the delivery of the project including extensive work on the tunnelling compound.

Detailed design activities required the coordination of a range of engineering disciplines including geotechnical, pavement, traffic, drainage, surface water management and treatment, as well as structural design of complex water retaining structures, buildings, retaining structures and security fencing. There were many environmental, geotechnical, planning and technical constraints that had to be considered during the design. RPS found innovative solutions to these challenges and delivered designs within a very tight programme. Our activities included:

Design of various structures

Civil elements of the pipeline including stone road and temporary sheet piling works

Tunnelling compound including 3D model

Civil elements of Landfall Valve Installation (LVI)

Development of ‘For Construction’ design documentation comprising Scope of Work, Specifications, Schedules of Materials and engineering drawings for issue to SEPIL’s contractor on-site

Surface water management design for all elements

Ongoing design support to SEPIL’s construction team

Construction began in July 2011 and was completed in December 2015. The Corrib Onshore Gas Pipeline won the Engineers Ireland Outstanding Project of the Year Award in 2016.

Dublin Bay Contract - North Dublin Drainage Works

Dublin Bay Contract - North Dublin Drainage Works

Dublin City Council

Ireland

The Dublin Bay Project was the largest urban drainage project ever undertaken in Ireland, providing for integrated networks and treatment at Ringsend for the whole Greater Dublin Catchment.

RPS oversaw all stages of planning, design, procurement and construction supervision for the North Dublin Works, comprising network sewers, Sutton Pumping Station and 11km subsea pipeline to Ringsend. These works service up to 400,000 population and cater for the medium term needs of the region including Dublin Airport and the North Fringe (Fingal / DCC) development areas.

The works include state of the art pumping and storage management, odour treatment, tunnels and the largest wastewater marine pipeline in Europe. It integrated the new works to the existing infrastructure of the area and eliminated a major untreated sewage discharge at Howth.

Bord Gáis Eireann

Ireland

RPS delivered this award winning national project for Bord Gáis Eireann on time and within budget in 2002.

RPS managed the large, complex project through the entire project cycle from pre-feasibility through design & planning approvals, contractor procurement and construction supervision. The comprehensive Environmental Impact Statement was also completed by RPS. The €400m project provided 300km of 750mm dia 85bar gas transmission pipeline and included over 450 road, rail, canal and river crossings including crossings of the River Shannon at Athlone and the Shannon Estuary (approximately 2km, max. depth 44m).

Crossing techniques employed ranged from open cut to thrust and auger boring to directional drilling and mini tunnelling. Construction was completed successfully through difficult ground conditions (bog and rock) and environmentally sensitive areas with minimum impact. This at times required the use of specialised and innovative techniques to enable construction to proceed on programme. Automatic welding of gas pipelines was first used successfully in Ireland on the Gas Pipeline to the West.

N11 Arklow Rathnew & N7 Newlands Cross Upgrade PPP

N11 Arklow Rathnew & N7 Newlands Cross Upgrade PPP

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.
