Our work

Work examples

As a subcontractor, our work sits inside our customers’ contracts with their clients. Each example states the programme, who our customer is, what we do on it and where it stands now.

Fibre network civils for SIRO and National Broadband Ireland

Fibre civils across Dublin and the neighbouring counties, carried out street by street from the main contractors’ work instructions. Much of the work put new sub-duct into existing ESB and eir ducts, with blockage clearance, new duct and chambers where the route needed them, and reinstatement behind every opening. It included duct routes for data-centre connections and work inside business parks.
