Joint venture Balfour Beatty CLG is celebrating after being honoured at the recent annual Construction, Quarry & Recycling Awards for one of its major and challenging project undertakings.
It was presented with the Construction Project of the Year award, sponsored by Sleator Plant & Mecalac Construction Equipment, during a glittering ceremony, compered by television and radio sports presenter Adrian Logan, at the Crowne Plaza Hotel in South Belfast.
Organised by the publishers of Plant & Civil Engineer, 4SM (NI) Ltd, it was attended by hundreds of guests and leading figures from the plant, construction, quarry and waste management sectors. With 20 separate categories, the event is widely regarded as Ireland’s premier platform of recognition for those operating across all sectors of the industry.
The event heard that the winning Project of the Year was a complex undertaking, involving a broad range of skills and exceptional management expertise. Covering 15,500 manhours, accident and injury free, the project was carried out ahead of schedule and seamlessly provided an Above Ground Installation for Gas Networks Ireland.
The new AGI was built on a brown field site and included all civil, mechanical and electrical works. Subsequently, 700m of 315mm PE outlet pipe was installed to connect the new AGI to the existing network, providing a critical boost to the existing gas infrastructure in Dublin.
This included a HDD underneath the busy M50 motorway at one of its widest points across the main carriageway and both slip roads and was approx. 250m long through brown granite. The solution developed jointly between Balfour Beatty CLG and Gas Networks Ireland was to install a 450mm carrier pipe across the motorway and install the PE through the pipe.
This involved a substantial site set up and site investigation prior to drilling and also the excavation of shafts either side of the motorway in excess of 8m deep in order to “pick up” the pipe once crossed over and return it to normal trench depth as quickly and compact as possible in order to return to normal trench depth; this included extensive trench support and development of temporary works designs.
Balfour Beatty and CLG Developments established the joint venture in 2011 to support Ireland’s world class infrastructure by providing emergency response, maintenance and construction services to Gas Networks Ireland; the contract covers all aspects of gas activities for the whole of the Irish network.
