3D Printing promises to change architecture and building

Large scale 3D printing is about to radically change the building industry

One of the longest running large scale 3D printing projects is based at the UK’s Loughborough University where since 2007 researchers have been working on developing the technology’s applications to the construction industry.

Loughborough’s technology, named Freeform, offers faster and more flexible ways of casting concrete and building structures using a computer controlled concrete pouring system. For property developers the attraction is cheaper buildings while for architects the technologies offer more innovative structures.

In late November the team announced a venture with Swedish building company Skanska SA to develop the world’s first commercial concrete printing robot.

The venture, which will include collaborations with companies including iconic UK architects Foster and Partners, Buchan Concrete, Scandinavian contracting giant ABB and Lafarge Tarmac, aims to have the first commercially available robot printer available by mid 2016.

Competing with the European venture is Chinese company WinSun who earlier this year showcased its 3D printer capable of producing ten houses every 24 hours. An interesting aspect of WinSun’s project is that the printing rig was build out of existing parts and controlled by an off the shelf Computer Aided Design and Manufacturing software system.

While the Chinese results are relatively crude, they show the potential for the technology. The economics of the WinSun project are enhanced by using waste building site material for the concrete which only increases the attraction of these machines to cost conscious property developers.

The Chinese and British are not just the only countries working on these technologies, in the Netherlands the 3D Print Canal House shows how techniques and materials are being developed while in the United States the University of Southern California’s Contour Crafting project is looking at how to use large scale 3D printing in a range of construction scenarios including building space colonies.

While using moon dust to build structures in space is some way off, both Freeform and WinSun show what will become commonplace on building sites in the near future.

These technologies promise to radically change architecture and the building industry with ramifications for jobs and the economics of building structures. 3D printing buildings is another example of how industries and employment will be very different by the middle of this century.

For businesses, it’s another example of how managers have to prepare for very different marketplaces.

Building great work

Mediocrity is something we have to avoid if we want to do great things.

“You have to understand Paul that we are building a structure designed to last twenty-five years,” sneered the consulting engineer as we sat in a site meeting on a high rise construction site just inside the City of London.

I sighed deeply and let the matter of cladding fire protection water tanks slide and pondered nearby St Paul’s Cathedral, wondering what Christoper Wren would have thought about the mediocre architecture being thrown up around his masterpiece.

The consulting engineer was a suitable person to build mediocre buildings, he and his firm were only on the project by virtue of the property developer being from the same masonic temple and the calibre of their shoddy and visionless work reflected their suitability for the project.

Apart from the pedestrian architecture and engineering, the lack of foresight extended through poor design right through to not allowing enough for future expansion of the building’s communications – by the early 1990s it had already become apparent modern office towers were going to need plenty of space for network cables and the lack of which probably contributed to the structure being totally refurbished in the mid 2000s.

That day was the beginning of the end of my engineering career as I found I didn’t much care for being patronized by mediocrities all too often encountered in the building industry in the mid 1990s.

At the time most of the architecture in London was pedestrian and bland late Twentieth Century mirror glass. The real tragedy being that modern construction techniques give architects and builders possibilities that Wren couldn’t have dreamed of.

Thankfully London snapped out of that era of mediocrity and today building like The Gherkin, The Shard and London City Hall show what’s possible with imagination and modern building techniques, although things can go wrong.

Mediocrities patronizing those who don’t share their narrow, bland look on life will always be with us, thankfully we don’t have to accept them in our lives.

If we want to build great things that push the boundaries or change the world, then those grey mediocrities have no role in our lives.

Where that consulting engineer and his masonic friends are today, I have no idea but it’s not likely they built any of the iconic buildings that now dot London’s skyline.

Living in an age of grey boxes

What does modern architecture tell us about our suburbs and society in today’s Australia?

If an era’s architecture tells us about the times, what do today’s houses tell us about modern society and values?

On Sydney’s North Shore lies a collection of old army bases, from the 1980s onwards the military started moving out and some of the land was handed over as national parks, other parts were converted into office parks or cafes while the disused married quarters were sold off to private home builders.

The old stores and administrative buildings have been adapted into artists’ studios and elegant, if expensive, offices. Overall, that’s been a success which has created quite a thriving businesses and creative community.

Many of the colonial officers’ and NCO’s quarters, impressive sandstone and wood structures, have become offices, restaurants or function centres. Although some are still looking for a purpose.

What happened to the functional three bedroom 1960s and 70s brick veneer homes that housed a generation of army brats is less encouraging and tells us much about the times in which we live.

A few of the old post World War II homes remain for Navy families in the still operating, and expanding, HMAS Penguin and these show us the houses that once lined Middle Head Road in Mosman.

These are perfect examples of the functional family homes that covered Australian suburbia during the 1960s and 70s. While nothing exciting or particularly pretty, they were adequate for their task as baby boomers built their families in the post war prosperity.

When they were sold by the Federal government most those modest family homes on Middle Head were bulldozed to make way for the grey behemoths of the 21st Century.

Like the Mc Mansions that crowd today’s suburbia, these feature four, five or even six bedrooms with on-suites, multicar garages and games rooms. Just as every child today has to win a prize, every room has to have a plasma TV.

These monuments to the modern consumerist economy triumphantly march along a road that once featured modest homes with gardens, trees and lawns.

In many ways these modern buildings represent the ethos of our time – grey, non-descript, poorly built, overcapitalised and dependent on cheap, never ending debt.

A striking aspect about them is their hostility to the pleasant surroundings and the 1930s mansions that make up most of the street. With their battleship grey, security features and blocky air raid shelter lines they look much more like some sinister military installations than the red brick army homes they replaced.

What’s also notable about these new buildings is many are empty. Some of them are being refurbished, only a few years after being built, and many are undergoing substantial repairs – a testament to how Australian building standards have declined in the past two decades.

Strolling along Mosman’s Middle Head Road its hard not to imagine that if Dorothea Mackellar were writing her iconic My Country poem today, she would have included the lines;

I love a sunburnt country
a land of capital gains

The tragedy for Australia is those old three bedroom houses could have been used by a visionary government to help low income families in Sydney’s increasingly unaffordable suburbs.

However we don’t live in visionary times and government assets today exist to be sold off as quickly as possible to Australia’s rapidly growing rentier classes.

There was little chance those modest housing blocks would become anything more than expensive, over capitalised gin palaces for bankers and the city’s well connected business elite who are never slow to see a coal mine or old military property going cheap.

Architecture tells us a lot about our times and the abandoned Middle Harbour army base is a good commentary on the phases of Australian development through the twentieth Century and the beginning of this century.

The houses also tell how Australians see speculating on overcapitalised property as a safer investment than building the technologies and businesses necessary to prosper in this century. How that will turn out remains to be seen.

What will be interesting is how our great-grandchildren see us and our legacy when they look upon the grey, hostile buildings we built to celebrate our good fortune in the early 21st Century.
