there's a difference between the world 'can' and 'should'.
Agreed.
I do not get your question:
you reckon they are both saying the same thing?
engineering reports should be correct and same within engineering standards.
However, the representatives of each company will use the engineer's reports to their companies benefits where the economics, risk, and profitability comes into the picture.
So, saying the "same things"? - engineering reports (yes, within limits) or the business proposals (no)?
we'll see..the reports are due tomorrow.
