In November 2004, MasterFormat expanded from 16 Divisions to 50 Divisions, reflecting innovations in the construction industry and expanding the coverage to a larger part of the construction industry. Updates were published in 2010 and 2012. A new strategy to classify the built environment, named OmniClass,[7] incorporates the work results classification in its Table 22 Work Results.
