Most technical specifications for building materials and building systems are available online from the manufacturer's website. The manufacturers provide this information to the public as a way of increasing awareness about certain technologies and giving the public an opportunity to assess the building material and determine whether or not it is suitable for the project at hand. Technical specifications can be given to the builder to assist in project planning, and can be in the form of MSDSs, CAD files, or any other kind of information.

Technical data regarding specific building systems can often be found on any of a number of websites that are dedicated to the do-it-yourself homebuilder or building enthusiast. In many cases, these websites will have detailed accounts of first-hand experience with the building product, as well as documentation of real-world tests. Some particularly informative building sites also have video documentation, providing homebuilders with excellent visual and audio cues for planning a building project.

One of the most useful types of building system technical specifications for builders, architects, and structural planners is CAD data. CAD files that detail each assembly and component part of a building system can help professionals analyze a project from the ground up, and aid them in the production of reports, structural or materials analyses, and provide digital images of the whole or partial final product.

Other Sources of Technical Specifications

Most companies will also furnish product specifications on request. If the manufacturer of a building system or product is a national company, then local company representatives are usually available for consultations and questions. In some cases (particularly when dealing with building systems such as ICFs), local contractors who specialize in that material may also be a good source or information.
