Rip open any building short of a nuclear reactor complex and you will find such differences. Nothing, ever, gets built exactly as planned. We have only a few photos, blurry ones at that. Hold off on the conclusions until reasonable evidence emerges.

Sure, changes often are required when plans come to a practical implementation, but they (should?) have to be documented and re-verified by the engineers/architects at least for structural components, and the plans should get updated to match the on-site modifications.

Are you suggesting it’s ok for the contractor to not follow the plans?

[Czarcasm]

Of course it’s not ideal, but in the real world the designs are often impossible or impractical to build. If work halted every time construction workers came across a design that didn’t work, instead of tweaking the design onsite and keeping going, nothing would get built.

So in the case of a tructural support columns or foundations, How does the contractor insure they are still safe and capable of performing?
