I got excited reading about using Techno Metal Post screw piers for deck foundations ("Building a Freestanding Deck," 12/11). This seems to be a simpler alternative than using a concrete pier. I did some research but could not find a prescriptive code for helical piers nor any listings with the ICC Evaluation Service for the technology. While the method looks viable, I wouldn't want to consider it if I can't get a permit and pass inspection. What are the additional costs for soils reports and engineering?
