I had a structural engineer come to my home to do an inspection. This was his findings:
"Based on my visual inspection of the floor framing it appears that the actual framing was done per the plans with regards to spacing, spans, etc. The only notable difference is the floor joist used. The plans call out for a 9 ½” BCI 5000-1.7 DF Joist, but I observed the joists to be Cascade Capital CCI-40 and also noted a Pacific Woodtech 1048 on the joists. The span tables for these appear to meet with the requirements of the actual spans for L/480."
I don't know what any of this means. The flooring sub contractor is prepared to rip the laminate out again and replace it.
This time they want to try a different product. I'm waiting for them to coordinate the tear out and install. Grrrr. So frustrating.
The engineer did say that it's possible that the laminate isn't designed to be installed over such a large area (my entire house is laminate flooring, 1593 sq. ft.) with the exception of two bathrooms and laundry which have vinyl.
I just want this to be over and fixed.
