A Comparison of Construction Classification Systems Used for Classifying Building Product Models
Building classification systems have established standard terminology and semantics for the construction sector. It is critical to use classification systems when dealing with specifications, structuring of documents and cost estimation.
Classifying building product models in a standard way is a major step in organizing building product libraries. By giving the proper classification code to the product models, they can be arranged for different purposes such as cost estimation.
However, several classification systems have been developed across the globe such as Uniclass in the UK and OmniClass in North America. Each system has been developed for a different purpose since the same collection of objects can be classified with different criteria.
This paper studies four classification systems that are being used for classifying building product models. We structured four specific criteria to study these classification systems. We first argue that each criterion has a major role in defining different classification systems. These four criteria are:
- purpose and properties of the classification system,
- framework of the system,
- grouping principle within the system, organization and
- taxonomies of tables.
Then, considering these criteria, a comparison among the selected classification systems is presented.
