Hazard

Pieces of masonry break off or the entire balustrade collapses.  

Potential structural strengthening project

Use a similar technique as for securing parapets - fit ties horizontally, with an emphasis on fixing the balustrades back to the deck structure (diaphragm).  

Possible first steps with a structural engineer

They assess the structural capacity of the balustrade and provide specifications for the required strengthening work.
