Cherrywood is a new mixed-use development of residential and retailing situated to the southeast of Dublin city in Dún Laoghaire–Rathdown. Balfour Beatty CLG, working on behalf of Gas Networks Ireland (GNI) commissioned Peter McCormack and Sons to undertake the installation of a new 450mm steel carrier pipe crossing of the M50 motorway by means of horizontal directional drilling (HDD) which will service the new development.
Peter McCormack and Sons Ltd also completed the insertion of the 315mm PE gas main into the 450mm steel carrier pipe post installation with two 5m deep connection shafts constructed either side of the HDD to receive and connect onto the 315mm PE gas pipe.
Award winning project
The success of the HDD and associated works was reflected by the fact that Balfour Beatty CLG won project of the year for the overall scheme at the Plant & Civil Engineer Construction, Quarry & Recycling Awards 2019.
The collaborative approach taken by all partners ensured that this project was delivered safely and ahead of programme for the Client.
The Cherrywood project further demonstrates Peter McCormack & Sons diverse skill set of not only successfully completing complex HDD’s, but also delivering the associated utility and civil engineering elements.
