Is there anything extra-tricky about doing an Amdeck that would prevent doing it myself? I'm asking because when I got a price on Amvic forms from the local dealer, they gave me pricing on wall forms, but gave me an installed price for the Amdeck.

Haven't installed the Amdeck system but I have used Insul-deck, It was quite straight forward. That being said, I am an experienced ICF installer with lots of concrete placement and finishing work under my belt.
I looked at the Amdeck system in Vegas and thought it to be a pretty user-friendly product. My only suggestion would be to get a pro floor finisher to do the pour, and if the Amdeck spec's say put in 1 support here, use 2. You can never really over brace when pouring concrete. I would rather have 10 more braces than necessary that 1 to few!!

Good Luck

Amdeck, although I either have used it; is the same principal as Lite Deck and Insul Dec, both of which I have used. Bracing is of the upmost importance as Paul points out, you cannot over brace this stuff, and also keep in mind the bracing remains in place for 21 days after initial pour..so is this going to affect the projects timeline?

Other systems are available on the market which don't require the bracing system, what is the reason behind choosing and insulated floor system, is it above a crawl space? If the space is conditioned both above and below the floor system look at alternatives.

I have used Amdeck. There is an installation manual on their website. The bracing requirements are far less than for other systems because of the 10' steel studs you set them on. The price of steel has gone up drastically so check this out when deciding which product to use. With 16 ga steel studs you can go about 12 1/2 feet between bracing rows. Get the bracing info from Amvic. I used 4x4 posts with Ellis brackets spaced every 4 feet in the row with no problems on several pours. You pay for the steel studs but save on the bracing and labor to put up the bracing. The Lite deck distributor wanted $12,000 to put up bracing for a roof. With Amdeck it was far cheaper even with the steel figured in. This might not always be the case. It is very easy to install. If you end up with 1/2 a block resting on only 1 steel stud make sure you put plywood under that section so it can't rotate when you pour. Amvic also has an excellent computer program to figure the rebar for your design loads. I just poured a 1000 sf roof with a 24 foot span. One row of bracing down the middle. It helps to use screed rails so you don't put to much concrete on the forms.
