Subject: QUESTION re: Grouting Equipment bases

1) Do you do foundations for equipment such as pumps, compressors, engines, vessels, etc.?
Yes
 
2) Do these typically feature grouting of some arbitary space between the base of the equipment (base plate, base angle, base frame, etc.) and the foundation?
Yes and no.  Some large equipment (steam powered electric turbines) uses a sole plate.  The sole plate is grouted in place and the equipment is placed on the sole plate.  Smaller equipment (some can weigh 160 tons) is placed on shim stacks that are shot in place.  The space is then grouted. 
 
3) Are you responsible for instructions for the people doing that grouting, and how do you instruct them if so?
Yes, in general.  We provide the materials accepted, and the general procedures.  It is more of a performance specification with some boundaries.  The millwrights know how to do it much better than we do. 
 
An argument between a colleague and myself is pending.
