What is a BIM Object?

At J.V. Tierney & Co consulting engineers Ireland, we are on a mission to spread the word about Building Information Modelling (BIM) and its role in the future of the construction industry in both Ireland and around the world.


We began using BIM software as early as 2005, and it is this willingness to embrace new technologies which has helped J.V. Tierney & Co. become one of the leading engineering consultancies in Ireland. As part of our continuing quest, we offer a little in the way of education on the subject.


So, What is a BIM Object?

BIM can be defined as virtual construction and within these computer-simulated buildings are virtual products and materials known as ‘BIM objects’. They are the digital equivalent of a real world material or product, such as a boiler, air conditioning unit or lighting.


A BIM object will have a 3D geometry, which describes the physical appearance of the product or material. In addition, it will contain metadata defining things such as what the object is, how it is classified, its performance, expected lifetime and so on.


The metadata of a BIM object used within a BIM model assists engineers to produce digital representations which can be analysed to assess how a building will perform in a real-world scenario.


BIM objects with specific manufacturer product data are vital in generating accurate visualisations, energy calculations and functional analysis.  


Two Types

BIM objects can be divided in two distinct categories; component objects and material objects. A component object is a piece of equipment with a distinct 3D geometry, such as an exhaust fan or duct. Material objects are building materials with no fixed shape, form or size, examples of which include carpets, walls and ceilings.


In Summary

We hope this gives you an understanding of what BIM objects are and the important role they play in mechanical and electrical engineering design. Please check back with us, as we will be adding new information and educational contact on a regular basis.
