An Excerpt from The Australian National Construction Major Project Review:

Equipping Tower 4 Collins Square with all electrical wiring services and communications cabling was not a job for the faint-hearted. It required technical competence, experience and a commitment to safety, budgets and the building schedule.

Ion Electrical was selected for this major contract as it has an excellent performance record in highrise electrical contracting. To add to the size of the project, Ion Electrical simultaneously completed the electrical work on Tower 2 Collins Square.

Project Manager for Ion Electrical, Rom Testa, said the tight time frame on the Tower 4 project required a solid commitment of personnel to meet deadlines. “We had up to 70 of our 140 total staff numbers on site at peak times. This enabled us to maintain progress without calling in extra shifts.”

Ion Electrical installed all electricals, fibre optic data cabling and mobile antenna system cabling. “The biggest challenge was setting up the lighting for the huge green wall in the Atrium,” Rom said. “It is reputed to be the biggest green wall in the southern hemisphere so it naturally took some careful design and planning to get it right.”

Ion Electrical was established in 2009 and has grown to become a market leader in commercial electrical projects and maintenance. Developing total electrical solutions for its clients is what Ion does best. It has recently completed major electrical works on Melbourne One, UOM Building of Architecture and South Bank Grand. Some of Ions current projects also include the Australis and Southbank Central Residential Towers as well as the Monash University Learning & Teaching Centre.

Rom Testa said that apart from the technical expertise of the directors and senior staff at Ion Electrical, the company employs only fully-qualified and ticketed staff with a retention rate of over 95%. “As a result we have a staff which totally aligned with our objectives, quality standards and commitment to exceeding our clients’ expectations. Our team is very proud of its contribution to the Tower 4 project.”
