Repairing Balcony suspended (spalling) slabs

I was asked why does it cost Big Buck$ to repair crumbling balconies



In the above case the slab can't be simply repaired the steel reinforcement and cracked concrete area needs to be cut out, replaced/repaired  & certified by experts.

Cause...Long term water penetration through cracks resulting in concrete cancer

 initial design/engineering factors that could have prevented this are  additional crack control reinforcement, extra concrete cover, lean concrete mix design, proper concrete placement & vibration,  & protective external waterproofing/coatings ,etc,etc

Unfortunately it's too late now  extra prevention is always better than cure.
