I'm a learning sprinkler designer and I have a question that's more about design efficiency.
When you lay out sprinklers in large Ordinary Hazard areas (assuming there's ceilings or unobstructed construction), what is the first step you take to drop sprinklers in the space?
Do you calculate the area of the room and then determine, at a minimum, how many sprinklers you need? Do you use drafting tools to automatically optimize the layout? Do you have circles around the sprinklers for approximate coverage and repeatedly shift until you like the layout?
I typically start with the area of the room and divide by 130 to determine the minimum quantity of sprinklers, then dimension each wall to start with an "optimum" spacing. I feel like this takes longer than it should, so I'm curious if there's a better approach I could be using. Any help is appreciated.
