The OmniClass™ Construction Classification System (known as OmniClass™ or OCCS) is a new classification system for the construction industry. OmniClass is useful for many applications, from organizing library materials, product literature, and project information, to providing a classification structure for electronic databases. It incorporates other extant systems currently in use as the basis of many of its Tables – MasterFormat® for work results, UniFormat for elements, and EPIC (Electronic Product Information Cooperation) for structuring products.
The OCCS Development Committee acknowledges the contributions of over one hundred individuals over the last five years, many representing the following organizations, who assisted with the development of OmniClass™.
