A 21-year-old electrician died at the scene, while a 48-year-old man, a subcontractor, was taken by ambulance to the Alfred hospital. The incident occurred on Hawthorn Road, Caulfield, shortly before 10am. Victoria Police spokesman Marty Beveridge said the two men had fallen the full two floors. Ambulance Victoria spokesman Paul Bentley said both men were initially pinned under rubble. "They were freed by paramedics working along side of the MFB," he said. One of those men has unfortunately died and the other man has been treated for injuries to his arms and legs and is in a serious condition. Police forensics experts and workspace are currently on the scene and roads in the area have been cordoned off. Nearby resident Nick Love, 25, had just got off a tram on Hawthorn Rd and was walking home when he heard a call for help from paramedics at the scene and risked his life to try to help the men. "There was one guy that was all right and had two broken arms and a few bruises and cuts but then once we got to the other guy he was under a lot of stuff and I just stepped back and let the paramedics jump in and do their thing," he said. Mr Love said the building materials involved were predominantly timber framing. It is understood the building was being converted into offices and apartments. Roads in the area have been closed to traffic and WorkSafe has been notified.
