The OmniClass Construction Classification System (or OCCS) is a 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. OMNIclass is identified in the National BIM Standard as the basis for knowledge and information management.

UniFormat is a classification system that arranges construction information based on functional elements, or parts of a facility characterized by their functions, without regard to the materials and methods used to accomplish functions. These elements are often referred to as "systems" or "assemblies". This system is commonly used in the preparation of Preliminary Project Descriptions, cost estimates and BIM systems and assemblies.
