KTL successfully delivers on PSCS role and the project management of Great Island-Kilkenny
KTL were awarded the Great Island-Kilkenny 110kV Uprate in 2021 and took on the role of PSCS (Project Supervisor Construction Stage) and were responsible for the programme of construction and management of multiple contractor duties and for the overall safe delivery of the project.
The overhead 110 kV line spans between Great Island 220 kV substation and Kilkenny 110 kV substation, passing through Counties Wexford and Kilkenny – the line was 49.04 km in length.
The project took 20 weeks and was successfully delivered during the following months - June 2021 to October 2021 and May to June 2022.
The nature of works managed by KTL included:
Replacement of 10no. Steel Tower including foundations
Reinforce 2no. Tower foundations
Assemble and Erect 10no. Towers
Replace 68no. Pole sets complete with hardware
String 121 (1-121) span of 430ACSR conductor
Access to 12no. Tower locations
Installed bird divertors over the river Barrow
The placing and removal of 500 bog mats/trackways
KTL as PSCS were responsible for the development of the construction health and safety plan, in line with reviewing the preliminary health and safety plan
Bernard Downey, Project Director KTL said, “We were responsible for identifying and including all relevant risks on site into the Construction Health and Safety plan, inclusive of access, security, interfacing with sub-contractors, public interaction, traffic management and site welfare. The completion of all temporary safety measures was put in place ahead of all stringing over roads, streams, LV/MV lines and HV lines.”
There was one Special Area of Conservation (SAC) in the vicinity of the route of this line, namely the River Barrow SAC and there were two masts located in this area.
Neil Coles, Project Planner KTL commented, “KTL is an ISO 14001 accredited organisation, and we are committed to the protection of the environment and the prevention of pollution via our planning process, service delivery process, waste management process and employee training and awareness.”
“The use of aluminium trackways and over 500 bog mats were laid to get all plant into the towers for the tower reinforcement. The ecologist employed by KTL provided valuable advice on where to install numerous silt traps and silt curtains to protect watercourses and drains where spoil piles from excavations were placed. We ensured there was a limited amount of plant taken on site to help with minimising our footprint.”
There was an archaeologist employed by KTL to be on site when needed to check any excavations for historical artifacts before being allowed to procced with the replacement of poles.
“KTL’s long-standing expertise coupled with its proven procedures on the deployment of numerous diggers, cranes and the use of a tesmec winch and tensioner for re-conducting supported the robust delivery of this project,” said Downey.
