What do seams look like; will they absorb moisture?
* 1/16" to 1/8" width.
* Filled with clear moisture-proof silicone caulk.
How long are the slabs, and can seams be avoided?
* The average slab size is typically 96" to 100" by 55" to 60"
* Project Manager will work with each customer to place a few seams
as possible in a kitchen. Seams are required based on slab size
and may be needed to maintain the structural integrity of the countertop.
How long are the panels?
* It is typically safe to have panels that are approximately
6' to 8' long, depending upon the stone type and bowl/cook top
configurations.
What type of sink can be used?
* There are few requirements when it comes to sinks. In order
to maintain the structural integrity of the countertop, we require
at least 3" of stone in front and back of the sink cutout.
Additionally, when using a cast iron sink, we will require the
cabinet installer to build a 2"x4" wood frame under the sink to
support it. Additionally, we recommend that if 2cm stone is being
used, and over mount sink should be provided.

"I suggest anything over 8" to have support. Generally that is the homeowner or contractors responsibilty. Over the course of time, something will happen with a large overhang. Not only you may need to replace the counter if it breaks, you or someone else can get hurt"
It is recommended by Tri-State Stone that any overhang beyond 10" is supported by one of the following methods: corbels to match your cabinets, a post or two at corners, a steel plate or an aluminum plate under the entire countertop.
You need to have a subtop to glue the granite to. This will prevent it from cracking when there are larger unsupported areas. Sounds a little sketchy to me that they didn't use subtop.
With 3cm, it is standard procedure to not use plywood decks. I see it done all the time. The downside is that you have to scarf it out and fill it with Bondo where the dishwasher sets or you have to set anchors in your granite to mount the DW. Also, corbels work well for your overhang, but at 10" I don't think you need it. What you might need is some support across the front of the sink, if you build a frameless cabinet.
3/4" (2cm) needs a plywood underlayment for support. This method is mostly used on the West Coast. On the East Coast, 1 1/4 (3cm) is common. 3cm is considered strong enough to not require an underlayment and is not used. As far as cantilever amount, it is generally given that 3cm can go 12" without support, but as the previous poster said, you would need to check with your granite guy as far as how far he's willing to go.
For weight calculations, 2mm weighs about 13 lbs per square foot and 19 lbs/sf for 3mm. The Marble Institute of America guidelines suggest an unsupported overhang for 2mm of 4" max, and 8" for 3mm.
Need to support over the dishwasher and the oven.
Dishwashers should not be attached directly to the granite countertop, but be side-mounted to adjoining cabinets. Special brackets are available from the dishwasher manufacturer for this purpose. Drilling into the bottom of the stone can cause stress cracks and discolorations in the surface of the stone.
