These condos were built in 1980, and investigated in 2003. The nominal water intrusion took 23 years to manifest itself in the form of a minor deck surface collapse which alerted the owner to investigate.
Needless to say it was well beyond the ten year statuette of limitations; this was not a restoration that was litigated. This was a 280 unit complex of high end condos, ranging in square footage from 3000 square feet to 6500 square feet.
The repair requirements included, re-framing the deck to current structural engineering codes, replacing guard railings, replacing waterproofing and flashing on the wear surface, replacing stucco and adding fresh air vents at the reconstructed underside of these decks. The decks varied in sizes, but this particular unit cost approximately $6000 to replace.
The overall restoration cost would have been approximately = 280 x $6000 = $1,680,000.
