Friends mourn tradie Nicholas Mackenzie killed in renovation tragedy Nicholas Mackenzie who died in wall collapse today. FRIENDS have described a tradie killed in a renovation tragedy this morning as a "superstar" who would be greatly missed. Nicholas Mackenzie, 21, was just two months from finishing his apprenticeship when he plunged eight metres to his death on a Caulfield South building site. A second man suffered fractures to his arms and legs in the accident on Hawthorn Rd in Caulfield South just before 10am as colleagues desperately tried to get to the pair buried beneath debris. Two electricians on the ground floor managed to jump clear of the wreckage as timber beams and equipment fell to the ground. Close friend and former workmate Jason McConville said the 21-year-old was a popular larrikin who was loved by everyone that met him. "He was just a superstar," a shaken Mr McConville told the Herald Sun. He was one of the most genuine blokes I've come across. He was always there for me, he was one of my best mates. It was a massive shock to get a phone call to find out my old boss was in hospital and my mate had passed away. Sam Clements, 21, said Mr Mackenzie would "give his own clothes off his back just to help a mate." He was someone who always had a smile on his face and brought out the best in you. Never had a bad word to say and is going to be greatly missed by everyone," Mr Clements said. MFB Commander Frank Besanko said that the electricians were fortunate to escape. "The roof as part of the structure has actually collapsed on to the flooring on the first level and the flooring has subsequently collapsed again," he said. The people that were on the scene assisted. Nick Love, who got off a tram shortly after the collapse occurred, rushed to help. He pulled debris off the men, but he said one of them was not moving and could not be helped. Then I got out of there; I was just getting in the way. WorkSafe is investigating the incident. with Wayne Flower and Anthony Dowsley
