architectural visualisation

3D architectural visualisation is a friendly and effective way to communicate your design to any audience. The French philosopher Jean Baudrillard thought that simulation would soon “replace the real”. Do you think it’s happening?

 

3D Modelling in bridges’ renovations save lives and the environment

“London Bridge Is Falling Down” is one the most popular traditional English nursery songs. World-wide there are different versions, but the core vision is pretty much the same. No matter the material of which it’s built, over time the bridge looses its load-carrying capacity and eventually falls down.

Kids sing the lyrics lightheartedly as collapsing is the natural innocuous way a bridge ends. But what the composition really describes is one if the worst structural failure you’d prefer not to see. The song actually omits to mention the tragic consequences the falling of a bridge can have.

The Polcevera Viaduct

The Morandi Bridge (officially Polcevera Viaduct) in Italy sadly reminded them to the world last summer.

Built between 1963 and 1967, the bridge linked two districts of the city of Genoa and crossed the river Polcevera. It became famous in August 2018 when it partially collapsed, killing 43 people who were crossing it. The continuous restoration works carried out since the 1970s were not sufficient to prevent the tragic event.

What’s most worrying and shameful is that it was not an isolated case for the country. The newspaper Corriere della Sera reported it was the 11th bridge to fall down in Italy since 2013. [1]

Bridges are highly stressed structures and on the long run they suffer from fatigue and pressure. This doesn’t mean that they cannot be restored and their life extended. 3D modelling can save lives and the environment. It can be a pivotal tool to verify bridges’ current operational safety and upgrade them.

Arup’s Bridge Information Model

The Arup’s Bridge Information Model (BrIM) is a great example of this application.

The 3D models help the working team to visualise advanced calculations, and enable advanced static and fatigue modelling under different scenarios. The expertise and knowledge acquired during the ongoing bridge renovation programme is then used to design new bridges. [2]

Arup, in collaboration with RHDHV and Greisch, has developed a sustainable remediation programme to extend bridges’ life for at least 30 years. Based on digital design, it will allow the refurbishment of eight of the 200 bridges in the Netherlands risking collapse. In the video below Arup explains in details their approach and how 3D models were used to find the most effective solutions.

To sum up, 3D Modelling can really save lives and the environment.

How to include the 4 pillars of sustainability in architectural project

Sustainability in architectural projects is a hot trend. We are all familiar with the concept of sustainability as a process or state that can be maintained at a certain level over a period of time, causing little or no damage to the environment.

The Brundtland Commission described sustainable development as development that

“meets the needs of the present without compromising the ability of future generations to meet their own needs.” [1]

The UK Government in the Annual Report 2000, January 2001, declared that:

Maintaining high and stable levels of economic growth is one of the key objectives of sustainable development. Abandoning economic growth is not an option. But sustainable development is more than just economic growth. The quality of growth matters as well as the quantity.”

The above mentioned definitions focus mainly on the economic and environmental aspects of sustainability. But there are other two pillars fundamental to sustainability: the human and social factors.

Human sustainability means maintaining human capital, which is composed by ‘the health, education, skills, knowledge, leadership and access to services’. [2]

Social sustainability means maintaining social capital, which is investments and services that create the basic supporting structure for society. [2]

Is it possible to include the 4 pillars of sustainability in architectural projects?

It surely is, regardless the size of the scheme! The video below shows a great example of how a small timber modular home was designed having in mind keeping a family together, enhancing multi-generational living and sharing responsibilities and costs.

Do you include any of the 4 pillars of sustainability in your home’s projects?
