The site of last Thursday's wall collapse, pictured in 2012, has seen a procession of failed developments since being cleared. Credit:Glenn Wilson ''The government has asked today the Building Commission to write to all councils, and indeed every builder in the state of Victoria, to be a part of identifying any other similar structures that may need to be checked as soon as possible,'' he told the ABC on Tuesday night. His announcement came after the French consulate named the third person who died as a result of the wall collapse. The woman's name is Marie-Faith Fiawoo, 33, a post-doctorate fellow in the engineering faculty at Monash University. Her parents were notified on Friday and are now en route to Melbourne. Bridget Jones and her brother Alexander, of Melbourne, also died in the incident, which is being investigated by the Coroner as well as by the Melbourne City Council, Worksafe and Victoria Police.

It is unclear that the hoarding had any purpose other than advertising Grocon's Swanston Square precinct. When Grocon bought the site from RMIT University in 2006, chief executive Daniel Grollo said construction would start the following year. Almost seven years later, only demolition and archaeological work has been done. RMIT University has since built a design hub on the south-east corner of the site, which it had retained. Alexander Jones. For the investigators, there is growing interest in the advertising board and its sail-like effect in a high wind. On Thursday, a freak and powerful gust of wind hit inner Melbourne around the time of the wall collapse.

Building union officials who occupy a building opposite the site say the board advertising the website www.SwanstonSquare.com.au was as much as one metre taller than the brick wall, which was about 2.5 metres. Peter Johns, a Carlton architect familiar with the site, estimated the board to be about 45 centimetres taller. Bridget Jones. Engineers Australia structural college chairman Richard Eckhaus said that if a hoarding was significantly higher than the wall it was attached to, it could interfere with the wall's safety. ''If you attach something to it to make it significantly higher, then it could lead to a collapse,'' Mr Eckhaus said. ''If you erect a sign that is higher than the wall it is attached to, it acts exactly like a sail.''

What remains unclear is how planning approval was granted for such a hoarding - if it was - and why no checks were made. Engineer and former Melbourne lord mayor Trevor Huggard has had an association with the site since 1980s, when CUB decided to consolidate its brewery operations in Abbotsford. He raised doubts about the legality of the brick wall, which appears to have been built in the late 1960s or early 1970s. The wall was not heritage-registered. Mr Huggard said that a building regulation dating back to the 1930s, but still in place, dictates that such external walls must not be more than 6 feet, or 1.8 metres, high. The wall was two brick courses thick with a cavity in between, a standard approach for an external building wall.

Mr Huggard has studied the photographs and concluded that the wall had been poorly constructed with a grossly inadequate number of metal ties holding the two courses of bricks together. He said there appeared to be little, if any, buttress or other supports. ''It appears to contravene every rule in the book,'' he said. Over three decades the site has been bought and sold like a Monopoly board property, with smart developers and real estate agents making millions along the way. Visions of casinos, corporate headquarters, bank offices, student housing and even internal winter gardens have come and gone without a brick being laid, while heritage structures such as the Malthouse on Swanston Street and CUB's original bluestone building have deteriorated. For years councillors and others concerned about the city's fabric have argued that sites such CUB should not be cleared - or, in this case, part cleared - until proposed projects are approved and financed.

The older structures on the site could, and should, have been maintained and made use of. "I'm quite concerned it would have blossomed and been very attractive to the student community that contributes so much to the life of that area," Mr Huggard said. He said the problem with such sites was they were cleared as bombsites, and neither developers nor authorities were obliged to ensure they were made use of or kept safe. "A bombsite is 10 times more dangerous than a finished building." In recent weeks property industry insiders have raised doubts about Grocon's capacity to realise its vision for the site.

But on Tuesday night Grocon insisted that work on the Swanston Square apartments would begin no later than April 8. Loading The company said in a statement: ''Our thoughts remain with the families of the three young people who died.'' With Benjamin Preiss
