JPLomeo Posted April 6, 2015 Report Share Posted April 6, 2015 Has anyone ever inspected a floor system that utilizes 4x4s as a combination beam/floor joist, (no real joists and no beams) and how do you think this system performs? They are spaced 48 inches on center. I inspected a home a little while ago (built in 1980) that had this unusual floor system. The floors inside the home were very uneven and lots of cracked -loose floor tile and grout, and some areas had excessive deflection underfoot. I have seen a handful of these floor systems over the years and the floors are usually uneven. Someone (probably the home owner) decided to stiffen the floors and installed additional supports in between the original structure, using more 4x4 posts but with lots of 2x4's and 2x6's poorly installed. The structure is just a royal mess. I recommended evaluation by a qualified framing contractor or an engineer. Now a contractor is telling my buyer that he wants to remove all the extra, poorly done re-enforcements and just restore the floor structure to its original configuration. He maintains that the re-enforcements alone have caused the floor issues. He may be partially correct, and I agree with removing all the crap, but I seriously doubt that the original floor structure will not feel like a trampoline. After all, why did someone go through all the effort to try and re enforce the floors, if they were fine to begin with? Any opinions much appreciated.
