Yes, unless you want a spaghetti mess. Since it's a pharmaceutical facility, you probably won't have very large bore piping so you might get away with a 24" top of steel differential.

See http://www.pipingdesign.com/designpractical.html, go to "A.J.'s Offset Page" and click "Layout". There's info there on elbow cutbacks.

I recommend The Piping Guide and the Piping Handbook. The former is a great reference for doing layout work and the latter is heavier on the engineering side. Definitely worth the money. Both can be found via http://www.pipingdesign.com/books1.html, or just do a Google search on the titles above.

Have you noticed that piping layout is a lot like puzzle-building?

Good luck,
