I would like to introduce our Civil Department to you. As a civil engineer myself I am very proud to showcase some of our schemes and introduce our key people who run this important department for GEDA. We initially formed in the early 1970s as a civil engineering company specialising in water infrastructure and road / bridge construction. Since then we have been providing comprehensive civil engineering services to private and public sector clients across the UK and Ireland. During the 1980s the construction department was developed and now specialize in the educational, residential and community sectors. We have found that the combined skillset of our civil engineering and construction staff bring added value to our clients.

The Civil Engineering team is led by fellow Partner John Coalter and his senior staff Maurice, Seamus and Paul, all of whom are committed and professional Civil Engineers with a passion for the industry. They have successfully delivered numerous schemes some of which are featured in this introductory booklet. Our key markets are Water and Waste water Treatment Works, Pipeline schemes, Reservoir construction and refurbishment, Industrial construction and Public Realm. With expertise across a wide variety of disciplines, we provide our clients with innovative and imaginative solutions that meet their needs in a safe, sustainable and cost-effective way.

Victoria Markets Pumping Station, L/Derry Client: NI Water Contract Value: £4m

Geda were the Civils Contractor and Project Lead on this scheme, which involved the design and construction of a pumping station and outfalls.

Network Improvement Scheme, Holywood, Co DownClient: NI WaterContract Value: £4.5m

The scheme was for the construction of a 7.0m deep pumping station with twin 1200mm diameter pumped out-fall pipes in the centre of Derry. Due to the ground conditions and the close proximity of neighbouring buildings a sheet piled cofferdam 25mx20m in plan was required to construct the pumping station.

Value engineering of the preliminary design allowed us to agree with NI Water the construction of the pumping station in one phase rather than the proposed two. This allowed significant time and cost savings.

A £4.5m sewerage improvements project delivering environmental benefits for the Holywood and Kinnegar areas of North Down and Belfast Lough coastal waters.

Involving the construction of new interceptor sewers and a new pumping station that enables the closure of the existing three CSOs.

The twin 1200mm diameter outfalls crossed a major dual carriageway in the centre of Derry at the location of a roundabout. Through close liaison with all stakeholders, including DRD Road Service, and a comprehensive traffic management plan this was achieved 4 weeks ahead of programme.

A substantial proportion of the sewer construction work involves micro-tunnelling works below and adjacent to the Belfast to Bangor railway line, and within the perimeter of the gas facility site.

A Design & Build project which involved the construction of a new reinforced concrete service reservoir (SR) on the site of an existing reservoir. The new SR was constructed, tested and brought on line prior to the demolition of the existing 0.5Ml reservoir. We were responsible for the full testing and commissioning of the works.

As part of the design, the scheme incorporated a fish pass designed to ensure the safe passage of fish through the turbine. We worked closely with the Council and Environment Agency to plan the works to achieve a successful outcome. Detailed Traffic Management Plans and Delivery Schedules were developed to ensure the safety of pedestrians using the shared access through the leisure centre.

Works included construction of a two compartment, 4.7Ml reinforced concrete service reservoir inlet, outlet and washout pipe work, chlorous dosing, along with associated level and flow monitoring equipment.

A new access road, kiosks and turning head were provided plus demolition of the existing 0.5Ml Service Reservoir and breaking up of significant mass concrete foundations.
