Well, I agree with 11echo.
The piping designer is the one who will be pointed at in the end. They gonna say, you did not checked your foundation size and that happen. 
,
they gonna say the pipng designer is responsible also for erection of stupid pumps selected by the client and will run out of thier duty point.. 
and you just have to agree (while making the official comments that makes you safe and give the calculations which proves your point of view).
and later make the installation and take responsibility of many things you never thought about.
can anybody have a way out of all the above situation, together with the foundation of course, by the way.. I already asked the civil engineer to start pouring the foundation from tomorrow…
Thaaaaaaanks for aaaaaaaallll
