Following successful work on several other power station projects, M.R. Site Services has just completed another installation of its Quantum Walkway system at EDF Energy’s West Burton Power Station in Nottinghamshire.
The new power station comprises three identical new buildings housing Combined Cycle Gas Turbines (CCGT) generating a total of 1300MW of electricity, in a major capital project.
The walkway was required to allow servicing of 100 rooflight
and ventilators on each of the three building roofs which are 100ft high with parapet walls on all sides.
Before M.R. Site Services was called in, the original concept was a galvanised mild steel system of raised walkways on a heavy steel support framework containing numerous penetrations through the roof sheets which would have been almost impossible to seal.
lightweight aluminium walkway from M.R. Site Services was quickly seen as the solution to the problem. It provides a trouble-free installation with stainless steel fixings to the steel roof sheets
. For this project, some 800 metres of Quantum
Walkway was installed on each roof, so totalling 2,400 metres complete with tubular handrails.
Joe Hendry, Project Manager at contractors Hertel Technical Services Ltd is delighted with the results of the walkway installation. “We have saved a massive amount of work in being able to attach the walkways to the Corus Trapezoidal sheets which also ensures effective sealing.” He continued, “M.R. Site Services have been involved in three previous power stations and their walkway system is ideal for the time saving benefits to Hertel. The company installation team completed their work very efficiently, and their quality and safety standards are extremely high.”
Walkway system supplied was in mill finish aluminium with special step fabrications and cable tray supports to accommodate power cables. The high quality system is designed and fabricated to BS5395 and BS6399 in 6082-T6 aluminium.
Before carrying out the work, M.R. Site Services submitted all calculations, designs and drawings verified by consulting structural engineers to EDF Energy in France for checking and approval prior to manufacture. The project was completed to a tight schedule and was on time and on budget.
Walkway systems have been successfully installed at many prestigious locations including Heathrow Terminals 3 and 5, Edinburgh Airport and the Diamond Light Source Synchrotron in Oxfordshire.
