What's covering the 1' under the beam? If you can cover that from the next bay over within the bounds of the obstruction rules then you are fine. Once a beam get so deep you can't so you are stuck with the 5 lines. If a relatively shallow beam there is a chance.

I need to design a sprinkler system, and I want to know if the following will be "ok" The hazard category per <FM> is HC2, distance that I have between 2 I-beans is 48.56' (center to center) and the distance from the botton of the I-beams are 47.57'. In HC2 the maximum distance is 12'. This mean that if I use center to center I need 5 branch (48.56/12=4.046)for sprinklers, but if I use the distance in the botton of the I-bean, I need just 4. Can I use 4 branches using the distances between the buttons of the I-Beam? Regards ________________________________ Este año estamos enfocados en mejorar nuestro servicio.
