Just a hint; This is where I buy around 90% of my books, it is usually the cheapest inside Europe and has a fast delivery:

Amazon.com has the book also available at quite more affordable price, and might be easier to use for you in North America. I have no idea how annoying it is to deal with your local customs.

Ferrocement forms are rather drawed "out skin", so there is a subtle diference and you have to provide for it.
To know where the frames, bulkheads, stringers, etc. have to be located, you need to perform structure calculations for ferrocement first. As Bito says you should contact an NA with experience in that material.

hi guillermo-yes I have seen the light on that issue and it didn't cost me much at all..and in fact ill have the frames nested and cut too. regardless of the material..i should have looked into that earlier-they are going on a dxf file for cnc cutting.-- costs and time savings are substantial.
