Since December 2013, Stacey Surveying has been monitoring fine movement in the historic Banana Alley Vaults on the corner of Flinders Street and Queensbridge St, Melbourne.

The survey is completed every 3 months to measure 60 control points spread throughout the 16 westerly vaults.

We can achieve millimetre precision and have been able to accurately track fine movements throughout the vaults since beginning this project.
