The design revolution is now and a new era has begun! Welcome to the Building Experience Modeling (BEM) era! This generation has been given the task to design and build sustainable green buildings using renewable resources, reliably and safely - in less time and with unnecessary outlay of costs.Delivering these complex solutions with reliability and precision is a challenge facing the building industry. With the introduction of new innovative tools available, designers are able to go from 2D to 3D CAD - using Building Information Modeling (BIM) methodology to digitally create design simulations to manage all the information associated with architectural projects.
(While Computer Aided Design (CAD) creates 2-dimensional (2D) or 3-dimensional (3D) drawings that don't distinguish between elements, BIM incorporates 4D (time) and 5D (costs) allowing users to manage information throughout project lifecycle intelligently, whilst automating processes such as programming, conceptual and detailed design, analysis, documentation, manufacturing, construction logistics, maintenance, building operations, renovations or demolition.)
Goethe said that “By seeking and blundering we learn ....“
Well I am not so sure that I would like to start a career in engineering knowing I was blundering in order to learn. But his point is bluntly put - that what we call 'knowledge' is gained through making mistakes. In other words, engineers push the envelope in design, making things bigger or lighter until they fail and then seeking out what went wrong.
In some cases, this leads to fundamental research to capture the laws of nature in formulae. In other cases, it leads to best practice or rules. This is how the aerospace industry has made flying one of the safest modes of transport.
Current practice in architectural and engineering design involves workflow methods that can have many stages and steps that challenge the efficacy and quality of the design and construction process. Unnecessary costs accrue through design collaboration delays and redesign or rework at any stage which challenges the business model of all participants.
In recent years many papers, both government whitepapers, research document and industry guru’s have voiced concern on the poor productivity within the construction industry.
Comparisons have been made with manufacturing industry where overall productivity has doubled over 20-30 years. So how did that industry achieve such gains and construction didn’t?
Continuing my theme of Shakespearean references, I
wonder if the bard was prescient foreseeing this question that has been asked many a time by managers when they start design projects?
“Should we do this in 2D, it will be quicker, or should we take the plunge and model it in 3D” – how many times has that been said in the last two decades or so, let alone 400 years?
The 3DEXPERIENCE platform from Dassault Systemes has played an important role in winning 2 awards in the Construction industry.
The Institution of Structural Engineers has awarded the 2017 prize for Construction Innovation to the team that designed and built The TallWood House at Brock Commons - an 18-storey mass timber hybrid building at the University of British Columbia (UBC) in Vancouver, Canada.
At 53m high, this student residence building has been recognized as the tallest mass timber hybrid building in the world. It is comprised of 17 storeys of five-ply cross laminated timber (CLT) floor panels, glue laminated timber columns.
Key to proving the construction process was the use of 3DEXPERIENCE to simulate the construction methods, from delivery of prefabricated parts to the work processes involved in assembling the building. CADMakers* used the 3DEXPERIENCE platform to simulate in real time all these interactions and hence improve on methods in a digital world before committing to the real world.
See this video to compare the virtual with the real.
Zaha Hadid Architects used CATIA 3DEXPERIENCE as the platform for the design of the world’s longest asymmetrical single stay bridge in Taiwan – The Danjiang Bridge. The design teams based in 3 locations across 2 continents used CATIA 3DEXPERIENCE On Cloud as the design and collaboration platform.
This greatly improved communication of ideas, management of information and enhanced the collaboration across the teams. The design team at Zaha’s were awarded the 2017 innovation in Collaboration Award from the Computing Construction Awards.
Both these awards show the gains that the construction industry can get from adopting the 3DEXPERIENCE platform as not only a 3D BIM tool but as a collaboration platform on which to store, control and manage all project data – meeting the requirements of BIM Level 3.

At Desktop Engineering, we aim to help our customers find ways of doing design or manufacturing quicker and of higher quality using software technologies. One of the approaches we can use is to use a rule based approach to capture knowledge to allow it to be re-used. Rules are those simple set of instructions, something as simple as a cooking recipe, that one follows that determines an outcome. So it is with engineering. Capture those rules and then reuse them in software and then you have design automation.
2D or 3D CAD
“Change or die” is the shorted version of Charles Darwin’s famous quote.
A little while ago I was in a meeting with a director of a major developer in London, trying to convince him of using 3D CAD (or BIM) models to help in construction projects and one comment put forcefully to me was
“I’ve built many a building with a pencil, paper and a fax machine so why should I spend money on 3D CAD information?“
I think we have all met these dinosaurs and we know what their future beholds!
If you think back to your first days in a design office, in a new industry fresh from college, you’ll remember that there was always a designer who’d been there many years. That was the person you sought for help, as they had all the experience of what works and what doesn’t.
It was Oscar Wilde who said “Experience is simply the name we give to our mistakes”, and so why shouldn’t you capture that experience to then avoid making the same mistakes.
Knowledge Based Engineering
There is a way this can be achieved which is by using a templated approach to design or to use another term “Knowledge Based Engineering“(KBE).
Knowledge Based Engineering sounds like a complicated process but our simple application and approach allows an organisation to capture best practises and methodology which become an automatic benefit for all concerned.
I can’t claim originality to this Shakespearean title which has suitable gravity for many companies in the construction industry. It was thought up by Dr Steve Lo of Bath University for a one-day conference I attended organised by the “Future Envelope” community of façade designers and manufacturers.
Drawing from members of the European Façade Networks, the Society of Façade Engineers and Centre for Window Cladding technology, the aim of the conference was to discuss how BIM can help or even hinder the design and construction process of building facades.
