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.
