I build schools and hospitals. Many engineers are hard headed idiots. I'll give two examples. 1/2 " × 6" hilti concrete anchors for #12 slack wires and 2 hole stainless steel industrial rigid conduit straps rated at 1000s of pounds for emt which doesn't fit in the strap, on roof blocks. We can't convince engineers to change straps. Engineers commonly can't understand that you can't fit 10 gallons in a 5 gallon bucket. And Electrical, mechanical, and plumbing engineers never talk to each other. You guys should serve internships in you chosen fields.
