Forum: I would appreciate insight into the following questions. If I have a Light Hazard room where the original design set sprinklers in a pattern of 12 x 14 ft, now they have introduced book racks taller than the original proposed thus requiring that this pattern and already installed pipe be altered to accommodate more sprinklers within the shelving units, sprinklers will now be located 6 x 14 ft pattern. The basic change will be achieved by installing 2 sprinklers from each of the originally installed outlets. The AHJ (A/E) is now requiring hydraulic calculations to justify the additional sprinklers. This area is not the most remote area of the project, so the question is; Aside from the fact that the changes do not affect the hydraulically calculated area, we argue that hydraulic calculations are based on area or room coverage and not in number of sprinklers, so since we have proved that we meet the required density with sprinklers that cover 168 Sq. Ft., it is not necessary that we revise these calculations to show density on sprinklers now covering 84 Sq. Ft. instead. Am I right?
