Is it just me or is engineering (or those who pretend to be engineers) going downhill. Here are examples over the last year.
Hired a company to design and fabricate some components on a project (details left out to protect the guilty). They had one degreed engineer (but not licensed) who couldn't design his way out of a wet paper bag. We ended up doing much of the design work for them which defeated the whole purpose of us trying to unload some work.
Got anchor bolt reactions from a vendor that were low by a factor of two.
Requested reactions from an equipment skid manufacturer for earthquake loads and was told they really don't understand code requirements for earthquakes and we should figure it out ourselves. (How did they design the supporting structure on the skid if they didn't know seismic loads?)
Asked vendor to provide calcs to justify motor horsepower for a system that is supposed to move over 50 tons. Got an email from him with a one line calc that was wrong.
Another equipment manufacturer framed a T support into a wide flange in such a way that the only moment resistance at the base of the T was through torsion in the beam. You could push on the T with your hand and rock it back and forth. (No , it wasn't supposed to do that.)
These are just a few of the many things I've been seeing. I think one of the problems is vendors who either don't have engineers on staff or their engineers are so specialized they can't do the area that I'm looking out for which is structural.
I realize we're all human and we're going to make mistakes but it has got to the point where I just expect the information I'm getting from vendors to be wrong. Anybody else running up against this?
