Construction Criteria Base (CCB) from the National Institute of Building Sciences

Construction Criteria Base (CCB) is an extensive electronic library of construction guide specifications, manuals, standards, and many other essential criteria documents. Published and updated continuously, CCB contains the complete unabridged, approved, current electronic equivalents of over 10,000 documents direct from participating federal agencies. CCB is the most effective tool available for finding and using current, approved U.S. construction criteria. Documents are available as PDFs and some documents are also furnished by agencies in word-processing formats or in the SPECSINTACT specification processing program used by the Army, NAVFAC and NASA. Documents are organized first into Libraries, then by Source and Category.
