Although Jim Miles (JM Construction) said that some of the plywood is in good shape, there are places where the plywood has been rotted by water intrusion. The black spots in the photo above are examples of the rotted wood. In the photo below can be seen more rotted wood in an inside corner. That is a common site of water intrusion and resulting wood-rot, said Jim Miles.
Apparently the bidding process has evolved so that the contractor now includes the cost of replacing all the plywood in his bid, and then credits back to the owners the amount that is not replaced. This is a procedure that hopefully will reduce the need for change orders and unanticipated cost over-runs. In the past several construction jobs on buildings there has been multiple special assessments due to cost over-runs that were the result of an imprudent bidding procedure. This building will be a good test to see if that problem has been corrected.
FYI - The contractors bids are based on worst-case scenarios, as if all the plywood is bad and has to be replaced. This way the uhjit owners do not get assessed multiple times. For Building 27, JM Constructin has just issued a change order giving a credit back (reducing the costs) for much of the plywood - while there are dark stains on it, it does not mean it is bad or rotted out and it does not have to be replaced.
