culled from more than 400 standards-developing organizations such
as ASTM, ANSI, ASME, IEEE. This Web site provides a searchable
database of documents and online ordering.
A product of ARCOM, Masterspec is a software tool that
provides comprehensive and fully researched specifications that
users can edit to produce project manuals and custom, in-house
masters. This avoids having to write specifications from scratch,
reuse outdated project specifications, or "fill in the blanks"
This tool has been endorsed by the American Institute of
Architects and other major building-industry organizations.
