Floor Truss Goof
 
3 Attachment(s)

I thought I was approaching this project wisely by paying a strutural engineer 350.00 to consult on the project. After he came to the house and saw the project in person he advised I could box in the trusses by gluing and screwing 5/8" plywood to both sides to stiffen them leaving holes for wires and a hvac duct. I even went ahead and got a building permit describing the project in detail with pictures. Now I understand I've created box girders and have compromised the trusses. The engineer who advised on the project will not return my calls. Below are photos. Any suggestions would be welcome.

Here are the photos. You can see that there are a lot of obstructions that the installers had to work around.

My problem was that the floor trusses were deflected quite significantly (1.5" over 8 ft.). Several of the metal connector plates were failing (peeling off) and at least one of the trusses was cracked.

The engineering firm for my condo designed the fix. Unfortunately, the condo board was not willing to jack-up the floor before the gussets were applied, so the floor is still out of level. Now, I am searching for some way to level the floor that does not involve jacking it up (which would appear to be out of the question now).
