In Jersey the slab can run from 350 to 500 on average site conditions and size and strength of cement will vary the price, I like to use a highway mix for equipment, but some guys try to save a few bucks and pour a cheap slab.

Quite a few bags of Quickcrete, you will quickly learn to make it 2x4's instead of 2x6's:grin:

I call the local mix as needed truck and have them mix up a just what i need on site and the strength needed for the job at hand. price is right and less work.

Contractor, one who contracts.

2 other options ..

sub it out. look in the paper for a service directory with someone that does driveways/concrete and let them do it and tack on a 10% to 25% fee.

or

Find a precast place and let them make deliver and set the slab. They can even put bolt holes exactly where you want them.


I figure I'm an Electrical contractor and not a concrete worker...

the easiest way to do this is to get a cement truck very rarely do i have to mix concrete by hand. i cant imagine mixing all those bags of concrete by hand
just figure lumber, cost to dig out the area and cement cost. a few hours is probably all thats needed. not much hard work. if you have the cement tools you can smooth it out yourself its pretty easy. just make sure the frame is level and your pad will be too

i think larrys idea of pavers sounds nice. i would like to see one of his generator installs:smile:

Never did a generator pad, I have made a few housekeeping pads. I just rent a small mixer from HD when I get the bags of redi-mix.

I do include wire mesh and rebar pin them to the existing slab, I round over the edges and provide a broom finish.

The last one I did stated with 2 x 8 s just so the thinest area was 4", the floor had a heck of a pitch.

If the pad is on a slope it will eat a lot more concrete . The cement trucks may have a minimum charge that excedes the cost of the cement. But it is still the way to go. My guess is the cost of 30 bags, a mixer rental, and extra time at the store, your not going to save that much.

If you do it your self don't forget a wheel barlel to go from the mixer to the pad. You may need to make a path out of plywood or lumber if there are small obstructions that a full barlel won't jump or to protect the landscaping from tire marks. If it is not off a main road truck weight limits may be an issue to check out or ask the cement co.
