The Cavan Town and Environs Development Plan, along with the Cavan Town and Environs Integrated Framework Plan 2020: Transportation Study, outlined the objective to alleviate traffic congestion while improving accessibility to the Town Centre. By commissioning the support of Cleantech Civils, the client aimed to fulfil the missions of both plans by improving pedestrianisation and traffic management while refining the local infrastructure.
Key Features of our Scope of Works
- The provision of 1.2km of new single carriageway road, cycleway, footway facilities and the realignment of approximately 310m of the existing L6624 Cock Hill Road and demolition of part of existing road.
- Demolition of the existing crèche, farm and waterworks buildings and associated tanks, pipe work and fencing etc.
- Site clearance, bulk dig, and cut and fill earthworks operation.
- The construction of 2No. roundabouts and 3No. road tie-ins on existing trafficked roads and the installation of a 2.1m diameter reinforced concrete culvert.
- The construction of over 1,000m of precast concrete piles and CFA piles with permanent sleeve and concrete beams beneath the intermediate roundabout in boggy conditions adjacent to Killymooney Lough.
- Associated civil engineering works such as design, preparation and construction of temporary works piling platform (3,000m2 in area) and construction of retaining walls.
- The provision of all traffic management including maintaining local access/egress to existing properties.
- Installation of road drainage, including storm attenuation ponds, petrol inceptors and outfalls, including the installation of ducting and services such as water main and sewer.
- The provision of permanent macadam surfacing, fencing, crash barriers, pedestrian guardrails, street lighting, hard and soft landscaping, road signage and markings and the provision for service providers.

How Cleantech Civils Added Value
Drawing on our years of experience and local knowledge, we rose to the unique challenges presented through this Irish infrastructure project. Our permanent design in poor ground conditions incorporated precast piles, which were to be driven in a grid formation – followed by caps on the pile arrangement. From here, geogrids would need to be rolled out over the caps. It was intended with the geogrids in place, the team could spread the site material over this in layers and up until the road subsurface.
The ground characteristics adjacent to the lake were extremely poor. To rectify the situation, we formed an assortment of precast and auger bored piles, topped with pile caps, ground beams, and a reinforced concrete slab. With this well-designed concrete structure, we could manage building the road over the area of concern with confidence. During the project, it came to our attention that a resident Smooth Newt species inhabited the wetlands area. To make sure the project did not impact the area’s newts in any way, we implemented site-specific conservation methods along Killymooney Lough, such as newt fences with observation programmes and continuous maintenance processes.
Another challenge was mitigating construction costs wherever possible, which is why we leveraged geogrids and site won material for road structure construction. Once all the structures reached their appropriate levels and aligned with acceptable standards, our team formed the road base with the specified aggregates in mind for the capping and creating of all drainage requirements.
Construction of this new road network meant we would need to divert the existing ESB line and install a new power supply. We installed a temporary power line which called for 12,000m of 125mm of HDPE pipework. Once our work was complete, the ESB swiftly decommissioned the temporary line – and the new infrastructure was powered permanently.
In an effort to reduce the amount of site material to be exported, we put our thinking caps on and formulated an innovative solution. After speaking with local landowners, it came to our attention that we could enhance the low-lying land by depositing excavated site material. Following successful liaison with both the landowners and Cavan Council’s Waste Management Department, we received the green light to create a licensed waste facility. This operated over two seasons to give the material ample time to dry out.
As always, Cleantech Civils is devoted to carrying out all work to the highest industry standards. This even added value to the local agricultural land in this particular case. We were also able to lower the haulage of multiple vehicles throughout the process, omitting unnecessary extra traffic throughout the town. This further lowered our carbon footprint while opening the door for sustainable solutions that could benefit the communities in which we worked.
