Seems like we have an AHJ not backing down. We had the reviewing engineer for the sprinkler plans write a letter stating that the criteria is in compliance with NFPA and that limited quantities of combustibles are permitted above the ceiling and still classify it as non-combustible. This is data cabling and waste vent piping that the inspector is drawing a line in the sand to provide protection above the ceilings of a large high school. I have been working getting informal interpretations from various entities to support our position.
GC is telling sprinkler contractor it was design build so no change order. But, specs say to put sprinklers above ceiling if structure is combustible or if steel beams are not fire proofed. In this project, the steel beams are fire proofed. The contract “intent” drawings call out to add sprinklers below stairs if combustible but no where else in the project. There is nothing to indicate sprinklers would be required above the ceilings. A similar school built the next jurisdiction over does not have sprinklers above the ceiling. I have been told other projects in this jurisdiction have the same construction and same situation with no sprinklers above the ceiling. One of them referenced is a hospital. I’m sure the data cabling in a hospital is far greater than a high school. This one is going to get interesting. And probably pretty ugly.

Plumber ran ABS drain piping. Electrician has some cabling not in conduit. Inspector is stating the space is now combustible and requires sprinklers above all ceiling areas. Has anyone run into this and how was it resolved? Drawings and specs do not indicate sprinklers required above ceiling spaces. But the GC is trying to force it down the contractor’s throat if it is required and of course it is now holding up the job. <https://linkprotect.cudasvc.com/url?a=http%3a%2f%2fwww.mfpdesign.com%2f&c=E,1,SttrIB9CfFxeMf-7pVmoE0k6_pscjwXmxhUTVEZGWqOrfVv_RPWQIfQUKROuTyjZCm-rOVW8fmWBaZ3y_z2Vqz49Ef7R7Xs_g_pgCVhDupBL3AWdHQD4Ndlu0rU,&typo=1> Travis Mack, CFPS, CWBSP, RME-G, SET Engineering Manager MFP Design 3356 E Vallejo Ct Gilbert, AZ 85298 NEW EXTENSION: 480-505-9271 ext. 700 NEW MOBILE: 480-272-2471 <mailto:tm...@mfpdesign.com> tm...@mfpdesign.com <mailto:travis.m...@ferguson.com> travis.m...@ferguson.com www.mfpdesign.com <https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.mfpdesign.com&c=E,1,rsfoiKZVjp0r4kS3D_wBk7ruQf4VYZLmhmkorPry67P4-UrK2tOI7g7FSH3jptAu9GNB7afW3q5NVVj-jOX4ldaCw1oexbBuMbLfKwuiDVE,&typo=1> Send large files to us via: <https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.hightail.com%2Fu%2FMFPDesign&data=02%7C01%7C%7C1121d49f9e6b4cf248f108d4df580e77%7C14e5497c16da42e69ffa77d19bafe511%7C0%7C0%7C636379016677342180&sdata=eGdMZGu2wXhUupGwgGTrqF3b54OP5%2BAZvlHhABSexWY%3D&reserved=0> https://www.hightail.com/u/MFPDesign LinkedIn: <https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.linkedin.com%2Fin%2Ftravismack&data=02%7C01%7C%7C1121d49f9e6b4cf248f108d4df580e77%7C14e5497c16da42e69ffa77d19bafe511%7C0%7C0%7C636379016677342180&sdata=tT5E7LsZjSmyreKi4gDCa70EWN%2BZodi%2FhbeCbHNRijI%3D&reserved=0> https://www.linkedin.com/in/travismack “The bitterness of poor quality remains long after the sweetness of low price is forgotten.” Need/Want a faster way to check material pricing?
