A Victorian man was killed during a concrete pour on the old Pentridge Prison site at Coburg in Melbourne's north Thursday October 15.

Yet the builder tried to deny access to CFMEU officials attending the site to supervise the safe retrieval of the concrete pump the following day.

The ABCC also phoned the Union, more concerned about the Union presence on the job than the safety matters under investigation.

It is understood that the 46-year-old worker was smoothing concrete on a first-floor building when one of the pump stands sank into the mud, causing the machine to tip. The pump's hose hit the concretor, knocking him into the wet concrete.

Work mates pulled him from the slab and called the ambulance. According to reports, paramedics attempted to revive the man for 45 minutes but he died at the scene. Ambulance officers said the man sustained serious head, chest, abdominal and shoulder injuries.

The CFMEU is concerned about work going on to clean up the site on Friday, ahead of further WorkSafe investigations of the incident.

‘No work should be taking place other than to retrieve the concrete pump which is in a precarious position,’ said CFMEU Victoria Safety Officer Gerry Ayres.

‘A 46-year-old father of two has been killed on this job.  It is morally repulsive that a company should be more concerned about its legal position than ensuring a safe workplace.'

Sixteen townhouses and over 60 apartments are being built on the huge prison site, as well as 14 luxury townhouses in another section, but the builder Westhomes Pty Ltd prefers to class it as a ‘domestic’ project.

The subcontractors working on the job come from both housing and commercial backgrounds. The concretor who was killed was deemed an ABN self-employed subcontractor.
