Transforming Dublin City
Stonepave went the extra mile on the logistically challenging Luas Cross City project
One of the most complex and significant projects to have been undertaken in Ireland for several years, the Luas Cross City has completely transformed Dublin’s transport system. Running along 13 stops over 5.9km, the linking up of the Luas Red and Green Lines cost €368 million to build and was delivered on schedule, running for the first time towards the end of 2017.
Such a challenging project required a contractor well used to tackling projects of this magnitude. Construction was carried out through a joint venture between John Sisk and Son and Steconfer, a Portuguese-based global railway construction company while O’Connor Sutton Cronin was the architect on the project. Landscape architects Brady Shipman Martin also assisted in the delivery of Luas Cross City.
With the largest granite supply contract in the history of the Irish State specified for the project, materials of the highest grade were a necessity for the build. The stone utilised on the project was specified by Transport Infrastructure Ireland (TII) and was chosen to satisfy the requirements of the local heritage encountered throughout the length of the scheme. Materials were approved over a six-month period to ensure the stone blended in with the surrounding environment.
Stonepave, a part of the outHaus Group, provided the huge and varied amount of stone that was required for Luas Cross City. Over 1,200 containers were shipped into outHaus over a two year period, a contract that included 5,000sqm of Spanish Azul Platino granite in a mix of pavings and carriageway setts. This particular material was chosen for its similarity to the existing Azul Platino which was supplied through the same source about 10 years previously. Praised by TII as ‘a perfect match’, the new granite blends perfectly with the existing material and proved an excellent choice. Stonepave sourced 20 stone types from China North and South, India, Portugal, Spain, Finland and Ireland (Irish Granite). The contract included 1,200 linear metres of Azul Platino kerbs, 9,000sqm of European 120mm deep Mid Grey cropped carriageway setts and Eagle Red & Rosa Porihno granite pavings and tactiles. Approximately 16,000sqm of 65mm silver granite flags were also supplied by Stonepave, along with 5,000 linear metres of oversized roadside kerbs and black granite tactile paving’s, to mention just a few. As the project had very low storage capabilities, orders were despatched daily to ensure it stayed on track with as many as 10 deliveries across a multitude of stops taking place per day. All materials were offloaded, stored and distributed in as little as one-tonne consignments by Stonepave. Installation of some Portuguese carriageway setts were also undertaken by the company. An extremely logistically challenging project, Stonepave proved why it’s the go-to provider of hard landscaping solutions to the local authority, commercial and domestic markets across the globe.
With the completion of Luas Cross City, passengers can now travel from St Stephen’s Green right through the city centre and onwards to the north‐west inner city suburbs, terminating at an interchange station on the suburban railway line at Broombridge. The new line has provided a much-needed transport route for the city, with reports estimating that almost 25% more passengers have used the Luas green line since it opened in December 2017. The scheme was delivered ahead of time with handover to the client and the operator achieved on the 8th of September. This allowed for driver training which meant the first passengers could climb aboard on the 9th of December 2017. Hailed as a triumph, completion of Luas Cross City has demonstrated just what can be achieved when collaboration between all teams is at the heart of a project.
