Project Summary
Coffey delivered the Belmayne Main Street and Road Improvement Scheme for Dublin City Council, a key infrastructure development that connects Malahide Road to Hole in the Wall Road via Belmayne Avenue and Parkside Boulevard. The scheme is designed to unlock adjacent lands for development of a new town centre and improve public transport, pedestrian, and cyclist access. The project includes approximately 900 m of new dual carriageway, upgraded drainage, and extensive traffic signal and public realm enhancements.
Project Description
Located on Belmayne Main Street and Belmayne Avenue in Dublin, the Belmayne scheme involved full road construction between Malahide Road and New Priory, providing bus lanes, traffic lanes, cycle facilities, and footpaths to support a new urban centre. The works were in a highly constrained, built-up environment with significant traffic volumes and multiple live interfaces, including nearby residential developments, schools, retail units, and public transport routes. Works required full stakeholder engagement to accommodate overlapping construction and utility activities and to coordinate around delayed third-party land access and ESB diversions.
Scope of Works
The works included:
Construction of approximately 900 m of new dual carriageway, including full road build-up.
Installation of new bus lanes, on-road parking, cycleways, and footpaths.
Construction of new vehicular junctions and access points.
Road resurfacing of Belmayne Avenue and Belmayne Main Street.
Upgrade of seven signalised junctions, including installation of pedestrian and cyclist crossings.
Installation of a bus gate and traffic signal infrastructure at Malahide Road.
Provision of a new drainage system including stormwater and foul drainage, attenuation, gullies, and associated manholes.
Installation of public lighting.
Tree pit installation, landscaping, and boundary works.
Technical Highlights
8,000 tonnes of pyritic subbase removed and disposed of at a licensed facility.
200 m of 1050 mm storm pipe installed as attenuation with hydrobreak and penstock.
250 gullies constructed in accordance with DCC specification.
UV lining used to repair 250 m of storm and foul sewers, avoiding deep excavation.
Full road reconstruction across multiple live junctions and access points.
Extensive traffic management including lane closures, stop-go systems, and pedestrian diversions.
Close coordination with DCC, ESB, emergency services, and developers throughout the works.
Environmental and Community Measures
Vibration, noise, and dust monitored due to proximity to homes and businesses.
Condition surveys completed on Belmayne Main Street.
Tree pits redesigned to better support growth.
Asbestos and contaminated material safely removed.
Regular communication with residents, businesses, and local groups to address concerns.
Added Value
Use of UV lining instead of open-cut excavation saved significant programme time and cost.
Rationalisation of tree pit design improved tree survivability and reduced future maintenance.
Proactive engagement with ESB enabled early works to proceed ahead of diversions.
Integrated planning with adjacent developers ensured minimal disruption to concurrent works.
