I do not know of any free site survey tools for predictive surveys. If you have a few APs to use, you can do a physical survey with some manual work. It would involve starting in one corner and placing APs. Then you see how far coverage reaches with your required RSSI. If you have a cisco card they have a site survey tool to help with this. Then you move the APs to the next possible spot and make sure you have enough overlap in your cells.
If you decide that this is a bit more than you bargained for, I highly suggest looking at prices for trained site surveyers, because it will cost more putting APs in the wrong place and re-doing it than a good site survey should cost.
If you want to look at predictive tools, I suggect looking at Ekahau and Airmagnet. They each have products to do predictive.
As for the firewall, I know cinder blocks that thick will drastically impact signal, but I have not seen them fully block it. Buildings with that as the internal construction type tend to require many more APs than stick construction.
If you decide to do the site survey, consider looking at this book..

Thanks for all the replies.
We will probably engage datacraft to do the site survey for us. they are suggesting us to get controllers and WCS, is WCS a must have?
IMO, WCS is most useful when you have multiple controllers, or when you are doing location tracking. I am not as happy currently with the reporting, but the next version will improve that. I think if cost is an issue, you can hold off with 1 controller. once you get more you can always add wcs.
WCS is not required but will certainly make your life much easier. Things such as RF heatmaps, the Planning Tool, config backups, controller templates, rogue detection, alerting, and much more make it worth its weight in gold.
WCS is needed if you wish to use location based services such as RF fingerprinting for precise location of rogue access points, clients, and RFID tags.
Thank you Brad.
We will be getting controllers for our sites located at different part of the world, may be in future we will get one copy of the WCS to place it at a central site.
Just to clarify, with multiple controllers you will definitely find WCS useful. My point was that with only one controller it may not be as worthwhile, but with multiple controllers tasks like code upgrades or even small changes can take a lot of time. I do not sell multi-controller solutions to customers without WCS. As an engineer I am not motivated by a bigger sale, but rather I have tried managing multiple controllers individually and it is not fun. I have had no regrets yet from anyone who has purchased it.
I just wanted to clarify my stance since I did not know you were looking at multiple controllers. If you haven't purchased yet, I definitely encourage you to reconsider WCS since I now know you are planning for multiple controllers.

Is any one having site survey manual for setup new cisco unified communication service for new site
It's best if you get someone to do a wireless site survey and you hang around and learn how it's done.
Following the few for the free site survay tools
NetSurveyor (good tool)
Xirrus WiFi Inspect
Heatmapper from Ekahau
