Completed Project: Asbestos Roof and Panel Removal, Installation of Fire Protection Boards and Aluminium Composite Panels– Electricity Substation
SCOPE OF WORK
The works included the removal and disposal of asbestos roof shingles situated on 4 steep 50 degree pyramids and the removal/replacement of the flat pitched areas.
Colorbond Ultra, both in Kliplok and custom orb style were used as the building was situated within a 5km radius of the ocean. Large industrial box gutters were removed and replacement with new 316 stainless steel material and flashings. New sarking and galvanised steel safety mesh was installed to standard underneath all roof sheeting. As a safety requirement fire retardant lining boards (calcium silica) were laid under the roof sheets in certain areas to prevent fire spread.
Around the building, large panels were removed and replaced with a more modern design and material. The new panels were aluminium composite panels with all of its fixings concealed to form more of an attractive appearance.
Aluminium custom designed louvres which were manufactured on site were also installed to give extra ventilation to the 132kv switch room.
Air ducting was also incorporated within the scope of works and the project was finished with a complete Height Safety Fall Arrest System to allow for future maintenance.
The project was crucial that work progressed under close monitoring and supervision from the site manager due to the transformers, switchgear and live exposed equipment being of high significance.
To ensure the risk of rain entering the building was eliminated the works were programmed so that all existing asbestos roofing removed, decontaminated, safety wire mesh and insulation laid and the new roof sheeting reinstated in that same working day.
