We were inspecting a large new construction house that had a fully detailed structural framing plan. The plan had been approved by a structural engineer, and it had been followed precisely by the framer. During our inspection, the framer was finishing up a few small things so we could feel the house bounce while the workers were throwing wood around and hammering walls into place. From our experience being on jobsites these past 20 years, a lot of these movements are normal while the house is still being worked on but we also felt something strange. There was a small sway to the building in the wind. It was a similar feeling to being on a rocking boat but it was very subtle and you could only barely feel it if you stood still. I knew something was majorly wrong! We called the structural engineer and they rechecked their drawings and realized that they forgot to account for the amount of large door and window openings in the house which severely weakened the bracing capabilities of the first floor walls. Worst case scenario is this house collapses in a major storm or best case scenario it develops large cracks in the brick and walls from the house moving in the wind which would have cost over $75,000 to fix (keep in mind this was a $1.5 million house). Because we caught it early, it only costed $2,000 to retrofit anchors and new interior bracing walls.
