    How big is the condenser, how heavy. If its a regular residential, you probably just need WWF (welded wire fabric)

    I’d argue you don’t even need that for residential.

    8 Ton Carrier . Pad must also be larger to incorporate fence cover (vandalism)'.

    I'd grab the install instructions and see how much clearance you need on all sides and above. At a minimum, 3ft all around would make a tech not curse you.

    A related question: what is the pad going to rest on? If it is properly compacted subbase and base -- 90 to 95 percent modified Proctor -- and that base is level and smooth, and the slab is a reasonable thickness, then you probably only need the welded wire. On the other hand, if you aren't going to or aren't able to compact the subbase and base, then you are counting on the rebar to hold the concrete together to spread the load to where the base can sustain it. And at that point, may I respectfully suggest that you get a licensed or registered Civil Engineer to answer your question... since there is no one good answer, never mind a rule of thumb.

    In general make the pad 6" larger than the equipment on all 4 sides. Check clearances. If it's a breathable fence (chain link) you could cheat on the clearance to the fence but you need access for the condenser coil cleaning and service Pad 4" thick with wire mesh set on top of compacted gravel

    If the security fence isn’t removable then 36” all around.
