My favorite example of this conundrum goes back to the transition to the requirement in 13 for the use of QR sprinklers in Light Hazard, and the reduction in design area allowed by their use. I believe this occurred in the '96 edition - whatever, our local codes were following earlier editions of 13. So when the engineer specifies to design to the latest edition of NFPA 13 and follow state and local codes, what do you do? QR sprinklers at the time were more expensive; but you could get the reduced design area, which could save money. Meanwhile, since the most recent edition of 13 called for their use, it was implied that QR was superior protection to standard response in Light Hazard occupancies.
Galen's response make the most sense, but in my example, we were a contractor competing for a job as a sub-contractor to mechanical - or maybe sub- to a sub- of the general. No one cared about such an issue during bidding. If you won the job, no one was going to listen to your esoteric discussion about the benefits of QR sprinklers unless you were willing to give a deduct change order. It was more difficult after receiving my PE, when I became professionally obligated (not just morally) to provide the best system for our customer. The QR issue was relatively minor and I am certain no one suffered injury because our local codes didn't adopt the latest version of 13 at that time. But it highlights the challenge and emphasizes a common point on this forum: engineers of record need to be more engaged in and take more responsibility for the fire suppression aspect of their job. And if the opportunity is available to contractors (with or without PEs on staff), they should take Galen's advice and propose alternative designs based on the latest standards. Mark A.

How does the forum feel about ignoring the more stringent requirements of the most current NFPA standards all because the AHJ hasn't adopted the latest year? As the standards have evolved with each new addition, they typically try to clarify murky wording of past standards, expand on topics, or add/change requirements based on the latest and greatest tests. So should we be purposely designing and installing and inferior product that more times than not is less safe just because the AHJ hasn't adopted the latest design guidelines. I've heard sometimes the AHJ doesn't adopt the new standard simply due to the financial impact of republishing their amendments and not merely because they don't agree. To me it seems morally/ethically wrong but I may just be on my high horse today. Thoughts?
