Redevelopment plans for the former Swanston Street CUB site have been on the drawing board for decades with numerous designs and owners.
The wall that collapsed was retained at the bequest of the City of Melbourne Urban Design department headed by architect, Professor Rob Adams.
The CUB site was the subject last month to an archeological dig prior to work on the new construction which was scheduled to commence in April 2013
Building company Grocon payed $1 million for the six-week dig, which ended on March 1. The dig was a Heritage Victoria requirement before Grocon
redevelops the land.
Sadly the wall which collapsed on Thursday had been standing in a dilapidated state and was scheduled for demolition as part of the new approved design.
There is speculation that the recently attached hoarding to the left of the wall may have caught the wind which then levered the masonry wall to collapse
The site is subject to a coroner and work safety structural report
