A redevelopment of the Hornsby Ku-ring-gai Hospital and the MLC Centre in central Sydney are among the five projects the union has visited for safety checks in recent weeks,which building industry sources have suggested were not legitimate.
In a furious letter to the Master Builders Association seen byThe Sydney Morning Herald,the union rejected suggestions it sabotaged toilets at the MLC Centre to shut down the site and encourage its primary builder,Probuild,to agree to the union's agreement.
"The CFMEU would not,and certainly does not have to resort to sabotage,"the union's NSW construction state secretary Darren Greenfield said.
"Builders,including MBA members,do a very good job themselves with substandard safety standards,of putting workers at risk of injury and death on site.
"The suggestion by you is offensive to the CFMEU,its officials and its members."
Master Builders Association NSW chief executive Brian Seidler,who argues the CFMMEU's agreement is unaffordable,has not yet responded to the letter,but said there was a"heightened awareness in the industry of the use of amenities to stop jobs".
"If this is true[that the toilets were deliberately blocked],that it is wanton sabotage,then there will have to be a very detailed investigation to identify who was behind this issue,"Mr Seidler said.
