The loss was several years ago and is not the only underground main break below a building I have seen. This one involved a building addition that was placed over the existing main. I don't remember if the owner at the time was the owner when the addition was built, but would speculate they were. Building addition and utilities designed by architects and engineers (strictly a fire main from a dedicated fire pump) and tested religiously to rigid IRI standards at the time (I know you youngsters out there won't believe that, but if you've been around 20 years or more you'll know that FM and IRI were very strict [appropriately so] until the insurance industry changed dramatically [unfortunately] in the early '90's). Approved by, probably everyone, but yet no one.

Futrell Sent: Friday, January 12, 2007 12:05 PM To: [email protected] Subject: RE: Fire Mains I was present when a 10" main running below a building where manufacturing was more than $1Million per day broke. The break, under the loading dock, turned out to be 18 feet deep and backhoes that could reach that deep could not get into the loading dock because the doors weren't big enough. You don't have to know much more to know this was a very expensive problem because the manufacturing operation could not run without fire protection!

NFPA has prohibited this for years but I still Architects and Engineers design underground fire supply mains under the slab to interior mechanical rooms. Fire sprinkler risers should always be installed at exterior walls to prevent what just happened at Sky View High School. Please pass this along to anyone in your firm who specifics location of fire supply mains. NFPA 13 2002 10.6 Protection Against Damage 10.6.1 Pipe shall not be run under buildings. Piping located under buildings is extremely difficult to repair, which is one of the reasons that 10.6.1 prohibits the installation of pipe under buildings. When buildings are built over exist- ing underground piping, the piping should be rerouted around the new building. When piping buildings requires repair, operations in the building must be curtailed, equipment may need to be moved, and the floor must be excavated. Leaks in the buried piping underneath the building can go undetected for long periods, and they can also undermine the building support. The location of system valves in the center of a building also places the system controls in the center of the building, which may not be desirable during a fire event. http://www.billingsgazette.net/articles/2007/01/11/news/local/25-skyview_g.t xt Joe Burtell, SET, CFPS Burtell Fire Protection, Inc.
