BSI BIM Conference – BIM Toolkit - Post 1 of 3 – Classification

Following a six week prototyping phase, a six month funded development phase and then five months of industry testing and further enhancements it was really good to be able to remove the ‘beta’ logo from the homepage of the BIM Toolkit in time for the 2015 BSI BIM Conference this year.

The removal of the ‘beta’ logo doesn't mean that the toolkit journey is at an end - but it is a sign that all of the functionality is working correctly and that it is ‘release quality’.

At the BSI BIM conference I presented three of the main concepts behind the BIM Toolkit: Classification; Levels of Definition and Digital Plans of Work. I have written three short blog posts to go through these slides as an introduction to these. This first blog post is on classification.

Before looking at classification in the construction industry it is worth looking at a world-leading web application like ebay. As a seller, it couldn't make it easier to classify the item you are selling. This allows ebay to gain valuable intelligence in terms of the millions of assets within its data store. It also allows potential customers to quickly find items they are interested in by filtering bases on specific properties. For example, a DVD has a ‘region’, a ‘length’, a list of ‘special features’; a t-shirt has a ‘size’, a ‘colour’, a ‘material’ etc…

For the digital construction industry, a unified classification system is important for the same reasons. A part of the BIM Toolkit project we have accelerated the Uniclass developments and have now published a number of these tables. There is consistency between the tables and each table covers objects of the same scale. The slides below illustrate this:
Uniclass2015 – based on the ISO 12006-2 framework for classification
Technical Article from Sarah Delany, Head of Classification at NBS
An example ‘Complex’ is an ‘Airport’
An example ‘Location’ is an ‘Aircraft standing area’
An example ‘Element’ is a ‘Barrier’
An example ‘System’ is a ‘Jet blast deflection system’
An example ‘Product’ is a ‘Jet blast deflector’
As part of the BIM Toolkit so far we have published nearly 11,000 classifications. We believe that this is the first truly digitally classification system. You cannot buy it in a book or download it as a PDF. It is available only in digital form – query it online, download it in a spreadsheet/database or query it using the documented software API.
