What is the ideal approach for fire sprinkler pipe to enter a building?
I find many engineer details show either an in-building riser (by Ames) or a ductile iron pipe with restrained pipe and fittings come under the building foundation and up into the building.
While this approach is acceptable, if we have the ability to coordinate with the structural foundation during design, would it not be better to drop the footing so that the fire sprinkler pipe can be sleeved through the vertical portion of the foundation wall?
I would think that running through the foundation wall would put far less pressure onto the pipe and joints itself. I understand when most installation/design work is completed is usually well after structural design, but when we do design upfront wouldn't this be the best-case scenario?
