Northern Ireland Electricity Networks has awarded two contracts for transmission tower foundation assessments and ground investigation to Power Grid Civils, which have a combined value of £3.8M.
Under the deals, Power Grid Civils will assess the foundations on electricity pylons between Coolkeeragh in Londonderry to Magherafelt as part of a plan to upgrade the 275KV line, as well as foundation assessments on pylons supporting more than 1300km of power lines.
According to Northern Ireland Electricity Networks, the Coolkeeragh to Magherafelt lattice tower power line was built in 1963 and is the oldest on the network in Northern Ireland. The power company wants to upgrade the route to carry more current but the capacity of the foundations of each tower on the line much be determined.
Power Grid Civils will undertake intrusive ground investigations to determine the foundation type, size and condition, as well as the capacity, of each tower foundation on the Coolkeeragh to Magherafelt.
Work on the second contract will be formed by similar work elsewhere on the network.
