Today’s complex buildings should no longer rely on fragmented communication through 2D drawings or pdfs, said Robert Beson of AR-MA (Architectural Research – Material Applications Pty Ltd.), in a recent presentation at the 3DEXPERIENCE Forum Asia Pacific South 2016.
Beson suggested that architects today have a responsibility to provide more than just design intent. When relying on 2D drawings, too much is left up to interpretation.
“It’s necessary to fully engage with the methods of construction, of manufacturing, assembly, logistics and installation,” Beson says. “We need to understand and engage our supply chain from concept through design.”

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.” Why shouldn’t you capture that experience to then avoid making the same mistakes?
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”.
Knowledge Based Engineering sounds like a complicated process but our simple application and approach allows an organisation to capture best practises and methodologies which become an automatic benefit for all concerned.
It is a way to create fully detailed designs and manufacturing information automatically.
Further, designers can then optimise, or “optioneer”, many different ideas or solutions quickly to enhance the design process.
At Desktop Engineering we have taken this idea and developed what we term an Intelligent Rainscreen Panel for façade designers and fabricators.
Using Dassault’s 3DEXPERIENCE Platform, we have captured the rules and formulae that drive the shape, strength, weight, and cost of a panel.
Factors such as blank sheet utilisation, different materials and thicknesses, and knowledge of manufacturing costs (laser cutting, folding) are all accounted for in the rules.
Further, the secondary structure or rails, that hold the panels have also been created as intelligent parts with similar information.
Combine these intelligent templates with an automated process for replicating them on a 3D building model and, within minutes, users are able to create a full design with manufacturing drawings, material schedules, and costs.
Alternate designs can be recreated by simply varying one or several parameters and then seeing the resultant recalculated cost and design.
Of course there is no single set of “knowledge” or “experiences”, as then there would be no differentiation between competing façade fabricators.
However, with the basis of one set of Knowledge within our Intelligent Rainscreen Panel, we are able to customise this set to suit particular fabricators.
Design for Manufacturing is a process whereby designers consider the impact of manufacturing processes in the way they design buildings.
Large components—whether large concrete panels or whole modular rooms for an apartment building—might be completed within a factory environment and delivered to a jobsite where they are connected to MEP systems.
To be successful in this approach, designers must work with building component manufacturers to understand their capabilities and design a construction approach that accounts for the logistics of getting modules to the jobsite and installed.
By considering how to optimize factory processes and then most efficiently assembling the modular elements in the field, designers can leverage strategies that greatly eliminate construction waste.
With reduced waste, building owners can adjust their budgets and apply significant savings from improved processes to better materials and overall more sustainable buildings.
Construction projects typically see amounts of waste near 30% due to redundant rework and inefficiency.
Without this waste, building owners could achieve significant project savings and reinvest in higher quality materials that are less harmful to the environment.
There are two potential approaches to reducing costs in construction:
AEC professionals can continually look for cheaper materials and labor to control construction costs. For example, vinyl is a very popular building material, largely because it is inexpensive compared to wood and other solutions. Yet PVC is made from chlorine salt using lots of electricity in a very environmentally unfriendly process.
Alternatively, AEC professionals can change their processes. By adopting a Design for Manufacturing approach, fabricators can automate many of the repetitive tasks that have to be done to produce a building. Fewer, albeit more highly skilled, workers can manage building component production in a safe, factory environment.
The latter approach may require a greater upfront investment, but the return on that investment can be recouped through the dramatic reductions in waste. Those savings can, in turn, be applied to investment in more sustainable building solutions. (more…)
By 2050, two-thirds of the world’s population will live in cities, the United Nations Human Settlements Program forecasts.
Meanwhile cities themselves are growing, with the number of megacities—those with populations greater than 10 million—expected to hit 41 by 2030, up from 28 today and just 10 in 1990.
The challenge is how to make sprawling, dense cities livable, sustainable and efficient for residents. But priorities for livability aren’t easy to define.
“If you have an older population, then things they see as priorities may be different than in a city with a huge number of young people,” says Stephen Hammer, manager of climate policy for the World Bank Group in Washington, DC.
The urge to become an engineer hits many people early on in life. Dr. Hicham Fihri-Fassi first felt the call as a young high school student. “I’ve always liked to innovate, and engineering enabled me to do just that,” he says. (more…)
Have you heard of hyper-loops, undersea hotels, and made-to-order 3D-printed buildings? These were just concepts a few years ago, but are reality now.
These structures need to be designed for either transporting people through natural surroundings, protecting them from natural surroundings, or allowing them to interact with natural surroundings.
The commonalities that underlay these structures consist of intricate linkages between product, nature, and life.
In fact, the original charter of the Institution of Civil Engineers describes the civil engineering profession as “the art of directing the great sources of power in nature for the use and convenience of man”, and herein underlies the role of product, nature and life. (more…)
Even as digital technology is transforming AEC processes, emerging digital platforms stand poised to transform construction products themselves.
Paris-based XtreeE is seeking to lead an industrial revolution in construction, civil and mechanical engineering by using 3D printing for large-scale architectural applications.
Through integrated consulting, manufacturing and technology, XtreeE provides education on how to use additive construction in the construction industry, while also developing end-user solutions and the technology needed to fabricate products.

Injury from musculoskeletal disorders (MSDs)—caused by lifting heavy items, performing tasks repetitively, working in awkward body postures, etc.—plagues many industries. In fact, the Bureau of Labor Statistics reports that in 2013, 33 percent of all worker injury and illness cases were the result of MSDs. (more…)
As we construct future buildings, we will start to see more mingling between architecture and virtual reality.
Imagine you’re a hotelier. Your newest property—let’s call it a high-end resort in the south of France—has gone into construction, but is not yet fully designed. Your firm is based in New York. The old way of designing the property would have involved several transatlantic flights and PDFs sent between you, the architecture firm, your marketing team, and any other stakeholders. Choosing the layout of the hotel rooms, making furniture selections, even just picking out materials and a color scheme, “can be a long and expensive process,” says Benoît Pagotto, a co-founder of IVR Nation.

The fourth industrial revolution – the Digital Age – is creating the drivers to transform the Construction Industry as it seeks to exploit the significant advantages to be derived from the effective and efficient use and management of data.
Industry-leading technology, developed for other sectors, is exponentially improving value and efficiency, and can be employed to propel Construction into the digital age.
This impacts not only the Construction Industry but also the logistic supply chains which support it, improving capability and skills, and contributing to the economies and construction potential of the countries involved.
The considerable amount of data which is created during the design, development, construction and utilization of the built asset, if properly configured and integrated, can be harnessed to drive value, cut costs and waste, and used to create a digital asset. This data-driven digital equivalent, when used by the end customer, can provide a dynamic platform on which to manage legacy, sustain the present and plan the future.
