Life-cycle Management of the Built Environment – BIM – Current Status

Published on by pcholakis

BIM usage, despite reports to contrary, remains minimal among large building portfolio Owners.  That is to say that the “life-cycle management of the built environment supported by digital technology” is not being practiced in an efficient, transparent, consistent manner by many, if any, public or private sector Owners.    The question is why?

Reason #1 – Most Owners don’t understand the basic tenants/requirements of life-cycle management.

Reason #2 – The lack of a robust BIM Ontology

Despite popular opinion, technology is NOT the issue.

 

BIM is in desperate need of a core glossary.   A core glossary a defining dictionary that enables definition of concepts, especially for newcomers to a language or field of study. It contains a small working vocabulary and definitions for important or frequently encountered concepts, usually including idioms or metaphors useful in a culture.

In a general sense, a glossary contains explanations of concepts elevant to a certain field of study or action. In this sense, the term is related to the notion of ontology.  

Automatic methods exist to a transform a glossary into an ontology or a computational lexicon.  Computational approaches to the automated extraction of glossaries start from domain terminology and extract one or more items (glosses) for each term of interest. Glosses can then be analyzed to extract  hypernyms of the defined term and other lexical and semantic relations.
