Ever wonder how to design systems for atriums, large open spaces, mechanical rooms full of ductwork and process piping? How about high tech fab rooms with exposed ceilings? Technology in the construction industry continues to introduce new materials and construction techniques and with it comes new challenges for providing adequate automatic sprinkler system coverage and installation. NFPA 13 contains the majority of the rules and requirements for providing proper coverage, however, as long as there are architects with imaginations, there will be buildings with spaces and areas that will force sprinkler designers to make judgments that are not found in the text of NFPA 13. It requires decisions that are sound in principle and practice. This seminar is designed to focus on these gray areas. This includes the spacing and obstruction sections as well as other important sections within NFPA 13. In depth discussions include several real life situations and actual designs and solutions. Recommended for third year designers or estimators, or NICET II certified.
