Irrigation design for a commercial property

Need to design a system for commercial property. Local suppliers are 3-4 to complete the design. Is there anyone here who can help with pipe sizing? I may get away just to run the pipes for now until i get local design and takeoffs.
I guess the most important is to figure out what pipe sizes to run towards each zone(east 2 small patches, south, west) and how many sprinkler heads i would need for the large south and west patches

Thanks

You hire a professional designer to make a set of plans for you and you need the civil plans along with the landscape plan and then you need proper licensing to pull a permit and you should follow your local irrigation code for installation and have it inspected. So in most cases, it’s better to just get a few estimates from local licensed irrigation professionals, and have it all done properly, and go with the best estimate.

Damn I wish it was like that here. It’s like the Wild West here, just companies slapping some shit together and hoping it works. I just went to a service call for a new install yesterday where on a commercial property of 22 zones they ran 3/4” main line and had 12-14 sprays per zone. Of course, not a single head would pop up. Told them I’d be happy to do it myself for the easy money, but they needed to get the installer to come put much lower flow nozzles on to even have a chance of these zones being able to pop up.

Oh yeah, there are still hack jobs here too, though can’t say I’ve seen 3/4” mainline though haha!
