My sentiments exactly. We did notify the "design team" of the dilemma (tail vigorously wagging dog), politely. We didn't tell them that they couldn't build it because there is no specific sprinkler designed to fit the exact circumstance.

Maybe they bought that expensive rated glass? Maybe they got an exception? Or maybe they made a mistake? You've no way to know which at bid time, so if it turns out they screwed up, that's what their E&O insurance is for. When you say smart Architect, my stomach get's all tight. Let's be kind, and call them "The Design Professional Team" under the architects leadership. The team may have elected not to involve a FPE, usually for financial reasons. As a result they are liable for that decision, and any resulting "Extra's" unless of course you were required by spec. to supply a FPE, and even then if you were, your scope was limited to NFPA 13, 14, 24 (Spec. section --------) you still would not be liable for the design of the "Rated Window Wall". You don't have to tell them "What to Do" only that their design doesn't work as drawn. If they ask how to correct it, you can give your opinion as a "Non-Design Professional" and suggest they have an FPE help with the final design. Yeah I know this just endears you to the Owner and the "Team", but it sure beats taking it up the shorts! Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O. Box 882136 Steamboat Springs, CO 80488 Tel: 970-879-7952 Fax: 970-879-7926 A smart architect would have known there are limitations on windows and glazing in rated construction. He should have been asking some questions before just "drawing up a drawing" and saying "make it so". Craig L. Prahl, CET It's permitted this way so what's a fellow to do? Tell the Architect/Engineer, Building Department, Fire Department and owner that they have to eliminate the doors and horizontal mullions from 80 ft. of glass wall? And by the way, the next time you want to use a glass wall you have to check with Tyco? By the time we find out about the rated glass wall all the permits are issued and construction has begun. It's probably a little too late to architecturally redesign the entire lobby area.
