    I draw electrical prints, but I'm in need of a concrete pad layout.

    Any size will do, just need general idea of how to draw a 12" thick pad to
    hold a large generator.

    Any help is appreciated!

    Me too...
    Is the Generator Outside (earth)? Inside (on concrete?)

    Any Local requirements regarding Seismic and the attatchment of the pad to an
    existing/new concrete slab?

    Do you need the pad to be re-inforced (ie: Re-Bar)?

    But given all that, you would be better off getting a Local Structural
    Engineer to do the design of the pad as there is the weight of the generator
    to also consider (12-inches is a thick pad by any means - but if you are
    talking 1500 Kw generator... may not be enough).

    I'd call for chamfered edges (personal tast).

    And if you have Seismic considerations, then there is a minimum amount of area
    around the physical dimension of the genrator base to allow proper seismic
    bolting down of the generator.

    Other than that, I'm also a bit unclear to exactly what you are asking. As
    far as a plan view is concerned, a rectangle with a note to it informing the
    contractor that a concrete pad is required is usually what we do here
    (Vancouver, Canada). We have in our Spec that the Contractor is responsible
    to have a local Seismic Engineer design the pad. We just call for that one is
    required under the contract.

    And in some areas hurricane considerations have to be accounted for....a
