Civil Engineering

Our qualified Civil Engineers provide advice and solutions for a wide range of private and public sector clients across a variety of sectors.

Our technical specialists have a proactive design philosophy giving careful consideration to economics, health and safety and the environmental impact of the design solution. Concepts and ideas are quickly realised and developed using the latest techniques such as building information modelling (BIM) and visualisations.

Our teams can provide the engineering input to a project at any point in its lifecycle, from concept and masterplanning, environmental impact assessments, feasibility and preliminary design to detailed design and value engineering. We also provide design support and supervision services during construction.

RPS provides expertise in all aspects of civil engineering and offers a focused comprehensive design service for:

Highways, junctions and linear infrastructure

Sustainable Drainage (SUDS)

Flood and coastal protection

Bridges, tunnels and crossings

Pavements and material specification

Design check certification

Inspection, supervision and assessment

Corrib Onshore Gas Pipeline

RPS provided a range of detailed engineering services to Shell E&P Ireland Ltd. (SEPIL) in the delivery of this 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

The Corrib Onshore Gas Pipeline won the Engineers Ireland Outstanding Project of the Year Award in 2016.

Galway Wind Park

 

 

RPS was geotechnical and drainage technical adviser to SSE Renewables / CGT for the construction of 58 wind turbines with an energy output capacity of 169MW at the Galway Wind Park.

RPS provided a full time on-site team of three technical specialists to advise SSE Renewables on the geotechnical and drainage works. Daily activities included design review, inspection of construction works, implementing the project quality assurance system and reporting of potential issues.

As the project progressed, RPS provided a full time civil site manager for the wind park. RPS was also independently commissioned by Grontmij/Sweco, designers to SSE/CGT, to inspect and certify the construction of the turbine foundations.

The construction of Galway Wind Park includes 35km of new access track, 25km of upgrades to existing track, 58 turbine foundations, two 100kV substations and 25km of 110kV underground cable.

The site is situated west of the N59 in Connemara and is largely peatland and conifer forest. The Connemara Bog Complex SPA and SAC are to the southwest of the site while one of the sites (Uggool) is located within the Oughterard District Bog NHA.

The green energy produced at Galway Wind Park will help to offset approximately 190,000 tonnes of CO2 emissions every year from fossil fuel generation. It will provide electricity for up to 84,000 homes, which is equivalent to almost 90% of the homes in County Galway.

Haulbowline – East Tip Remediation

 

 

Haulbowline Island was the location of Ireland’s only steelworks which operated between 1939 and 2001. From the early 1960s, waste from the steel production process was deposited on an area of reclaimed foreshore, which became known as the ‘East Tip’.

The East Tip predominantly comprises stockpiles of waste slag and mill scale throughout the 9 hectare site. The overall Haubowline Island Remediation Project represents a multimillion Euro investment by the Department of Agriculture, Food and the Marine, through their agent Cork County Council. The island, which is also home to the Irish Naval Service, only has one land-based access point across two bridges and this infrastructure also needed significant upgrades to facilitate the remediation project.

RPS provided environmental and engineering consultancy services for the preparation of an outline remediation design, EIS, waste licence application and planning application for the East Tip. A planning application for the remediation of the East Tip and its transformation into a public recreational amenity was approved by An Bord Pleanála in May 2014 and a waste licence was subsequently granted by the EPA in July 2014. RPS is also providing design, procurement and contract management services to facilitate the delivery of the remediation solution.

Remedial works designed by RPS began in 2014 with the repair of the bridges to the island and the upgrading of the access road. Most recently, RPS has managed a number of advance works contracts (including demolition, site clearance and preparatory works) through detailed design and construction completion. The main remediation works contract commenced construction in July 2017 and is delivering a sustainable design solution through re-profiling of the site, construction of a perimeter engineered structure around the East Tip and installation of engineered capping and surface water drainage systems. The ultimate landscape masterplan which is currently being delivered will comprise a public parkland amenity with picturesque views of Cork Harbour. It is envisaged that construction work will be substantially complete by the end of 2018.

M8 Raith Underpass

RPS acted as the contractor’s designer on behalf of Transport Scotland for this major £400m DBFO project comprising a new M8 dual three-lane motorway section between Bailliestown and Newhouse, with three new grade separated motorway junctions and amendments to two existing motorway junctions.

The Raith Interchange is an extremely complex interchange of strategic importance to Scotland with over 100,000 vehicle movements per day. Designers faced a unique engineering challenge at Raith in developing a new elevated free flow rotary above the existing roundabout and the construction of an underpass beneath it, all in a flood plain adjacent to an area of environmental sensitivity, massive artesian pressures, variable ground conditions and live traffic conditions.

Earthworks for the underpass includes a propped secant pile cutting 600m long and 15m deep in loose sands and gravels under artesian conditions which required complex temporary works design and dewatering. The underpass, located in the Clyde floodplain, presented significant flotation problems requiring a dense array of ground anchors secured into bedrock. The design team of permanent and temporary works designers, structural and traffic management engineers, hydro-geologists and environmental scientists worked closely to achieve the optimum solution.

As part of the production of the GIR, we undertook a detailed desktop study of the available geotechnical information. This included 12 phases of ground investigation for the project, ground investigations from the 1960s for the original motorway construction, as built records, mining records, including coal authority reports, historic maps, contamination assessment reports for adjoining developments and other geological maps and memoirs.

The footprint of the M8/M73/M74 covers an area of dense historic mine workings, with a multitude of shafts/adits and worked out seams at shallow depths that posed a significant risk to the construction works. A programme of remediation, comprising extensive cavity probing and consolidation grouting was implemented prior to construction. The project was awarded the ACEI Design Excellence Award (Overseas) in 2018.
