SC sitting on money raised to replace dangerous common property windows

All,

In 2014 our OC raised money to replace the leaky common property bedroom windows. My share was $35k for two windows.  This money has been sitting in the OC account for the past 4 years and now they say they need another 2 years and more money.  They are yet to commission a project manager and yes, this building is fraught with problems.  I took my $35k out of my mortgage and I calculated that if I had left it there I would be approximately $6k richer now. There is no logical reason why the SC is delaying this especially because 3 windows have fallen to the ground putting people’s lives at risk.

We have quotes and all the supporting technical documents.  We even have a builder.  Four owners lodged with Fair Trading to push the project forward but the SC refused to mediate. 

I take exception to this inefficient use of our money. Can something be done about this?  Has anyone experienced this kind of issue before and do you have any suggestions how we can get our leaky common property windows done quicker? 

Thanks,

Jan
