ANCIENT MUD MEETS 21st CENTURY 3D

To explore the possibilities of mud architecture, Rael San Fratello has created 3D-printed prototypes that take cues from historical earthen construction built along the Rio Grande river.

Led by architects Ronald Rael and Virginia San Fratello, Rael San Fratello created four mud structures as part of its Emerging Objects investigative series into 3D printing.

The project called Mud Frontiers resulted in 3D-printed designs – Hearth, Beacon, Lookout and Kiln – that the studio believes could help to provide solutions for more affordable construction.

The structures take cues from the origins of the Rio Grande watershed in Colorado’s San Luis Valley, formerly the edge of the US-Mexico before 1848. Here, traditions from Ancestral Pueblo cultures date back to 700 CE and the Indo-Hispano cultures of northern New Mexico and southern Colorado date back to 1598.

The Emerging Objects team began by researching processes typical to the area, such as hand-modelled earthen structures, and mud and pottery that harvest clay from Sangre de Christo and San Juan mountains. They then worked with 3D ceramic print company 3D Potter to make a small portable robot called Potterbot XLS-1 to print designs on the sites they sourced soils.

“What we learned was really how accessible, robust, and powerful it was to print large scale structures so quickly using the soil just beneath our feet” Rael told Dezeen.

“We discovered work flows for printing, material mixture processes, structural applications, and theories about new and old ways of living and designing for the future using humankind’s most humble material.”

Hearth comprises a thin mud-wall reinforced with rot-resistant juniper wood.

The sticks are used to join two walls together and protrude on the outside of the structure but are hidden inside – a relationship the architect likens to the “cultural differences between the architectural traditions of pueblo and Indo-Hispano buildings”. A curling mud bench wraps the inside of the tiny enclosure to meet a fireplace in the middle where juniper wood is burned.

Beacon was created to find a way to use a coiling mudwork to make the wall as thin as possible. Lights illuminate the indentations along wall at night time to give the structure its name.

Lookout, meanwhile, uses coils to create a staircase. “A dense network of undulating mud coils is laid out to create a structure that can be walked upon,” Rael added. The design also lays mud piping inside the walls into cross-shapes that can be used to create pockets of air that bolster the insulative properties of the designs.

“This also demonstrates how wide, yet, airy walls, can create interior enclosures that represent possibilities for insulation, especially in the harsh climate of the San Luis Valley that can drop below -20 degrees fahrenheit in the winter,” Rael said.

Kiln forms a culmination of a number of findings, including the coiling and criss-crossing mudwork, and adds a kiln for firing the 3D-printed vessels. The locally sourced juniper wood is are fired with juniper wood that give it a range of textures and hues.

“The products of the kiln, fired micaceous clay learning from the traditions of Taos and Picuris Pueblos, are hybrids of technology and technique,” said Rael.

“Emerging Objects explores these frontiers of technology and material using traditional materials (clay, water, and wheat straw), to push the boundaries of sustainable and ecological construction in a two phase project that explores traditional clay craft at the scale of architecture and pottery,” Rael said.

“The end goal of this endeavour is to demonstrate low-cost and low-labour construction that is accessible, economical and safe is possible.”

A particular highlight of the history is coil pottery, which uses layers of clay ribbons to form pieces.

Playing with this technique, the team made 170 vessels featuring varying bulges and markings – using the Potterbot to print the vessels with a ceramic 3D-printing software. It then developed the process to create a larger, 3D-printed adobe construction resembling series of bulging, rope-like threads from local clay.

“Excavated pit houses and above ground adobe structures defined the architecture of the Mogollon and by AD 400 this region witnessed the development of a distinctive, indigenous coil-and-scrape pottery tradition known as EI Paso Brownware,” said Rael.

Mud Frontiers by Emerging Objects was initiated in response to an article in the Smithsonian magazine called “40 Things You Need to Know About the Next 40 Years”. Number one in the list stated that “Sophisticated buildings will be made of mud”.

As part of the project, Rael San Fratello were testing a portable robot that they had created,

It was used to print the mud walls in varying patterns that related to traditional techniques

 

Other projects that have similarly experimented with mud construction include a biodegradable house created by 3D-printing technology developer WASP from soil and agricultural waste. French architect Stephanie Chaltiel, meanwhile, developed a prototype for emergency homes that is formed from a domed lattice sprayed with a mixture of clay and fibre using a drone.

Rael, an architecture professor at the University of California, Berkeley, and San Fratello, who is also an associate professor of design at San José State University,  established Rael San Fratello as an architectural research studio.

The studio gained international media attention earlier this year when it installed three pink seesaws in between the metal slats of the US-Mexico border wall, so that children on either side can play together.

The worldwide 3D Printing Materials Market is expected to reach $4.03 billion by 2025,

at a CAGR of 20.7% during the forecast period of 2019 to 2025.

3D printing is one of the fastest growing technologies and is being rapidly adopted for manufacturing and other applications by various industries. According to the National Conference of State Legislatures organization, five important industries that have the greatest potential to be transformed by 3D printing in the next 5 to 10 years from 2017 include Heavy Industry, Automotive, Consumer Products, Healthcare and Medical, and Aerospace.

3D printing technology has been evolving faster than other manufacturing technologies as it can influence manufacturing processes and help businesses perform to a higher level. Further, 3D printing manufacturing line is easier to alter than the production line for traditional manufacturing. This makes it preferable for the bulk equipment manufacturing processes. Due to this advantage, industries such as aerospace, construction, and automotive have started adopting this technology aggressively.

The key players operating in the global 3D printing materials market are Stratasys, Ltd. (Israel), Proto Labs, Inc. (U.S), 3D Systems, Inc. (U.S), Materialise NV (Belgium), The ExOne Company (U.S), The Hewlett Packard Company (U.S), EnvisionTEC Inc., (U.S), Evonik Industries AG (Germany), EOS GmbH (Germany), Zortrax (Poland), Markforged Inc., (U.S), Sculpteo- a BASF Company (France), Tethon 3D (U.S), and Arkema S.A. (France) among others.

Project Etopia – Giving Life to Self Build Dreams

Off-site eco developer Project Etopia recently announced the acquisition of self-build specialist Tribus Homes.

Last year, the two firms formed a partnership under the ‘E-Tribus’ banner, but Project Etopia has now bought the company, including its manufacturing facility in Devon.

Tribus Homes was created to help people build their dream homes. To start with, the firm employed timber frames, but later progressed to using the same Structural Insulated Panels (SIPs) used by Project Etopia.

These can be fitted with Project Etopia’s smart home technology — including lighting and ventilation — as well as Etopia’s Energy+ configuration, which generates and stores electricity.

Located just outside Tiverton in Devon, the Tribus manufacturing facility is capable of producing 200 homes a year. Etopia plans to use this factory to showcase the kind of micro manufacturing facility that can be set up around the country to support councils in their house-building ambitions using off-site technology.

These factories, set to be smaller than Etopia’s 2,000-a-year capacity unit in Ellesmere Port, can be set up in six to nine months.

In recent years, self-builds have become more popular as house prices have continued to soar and people have struggled to find the homes they want in the right areas.

Lee McArdle, who co-founded Tribus Homes, will remain its managing director, and a rebranding process will begin this year.

Joseph Daniels, chief executive of Project Etopia, said: “We are delighted to formally bring Tribus Homes under the Etopia banner. This acquisition means we can use Tribus Homes’ manufacturing facility in Devon to produce up to 200 new homes a year in the South West without needing to transport goods around the country, making developments much more sustainable.”

He added: “The factory is a prime example of how a number of satellite, small-scale facilities can be positioned around the country to create local jobs and deliver homes. Tribus will continue to provide people with their dream self-build homes, all of which will feature the smart home and energy technology incorporated in all Etopia projects.”

EUROBRICK: OFF-SITE CONSTRUCTION AIDS ON-SITE SAFETY

The Covid 19 pandemic presents unique challenges to all business sectors including construction. One of the most pressing difficulties is keeping up productivity on site while practising the social distancing measures as per government guidelines.

 

Utilising off-site construction as much as possible can be key to achieving project schedules while observing best health and safety practice. This has always been a benefit of modular construction and is now more significant than ever before.

Eurobrick have supplied brick and stone slip cladding to the Modular Building sector for nearly 30 years. Director Richard Haines talks here about the advantages of using brick cladding to maintain a brick finish with off-site construction, particularly in the current climate.

 

Error, group does not exist! Check your syntax! (ID: 6)

 

“Eurobrick systems are lightweight and easy to install. In a controlled factory environment, an installer should be able to install at least 1m² per hour but an experienced installer may do a lot more. Brick cladding only requires semi-skilled labour to install too, so with the increasing skills shortage in the construction industry, reducing dependency on traditional skilled labour is advantageous.

Where installed in a factory environment, our systems are robust enough to withstand the stresses of being transported to site and craned into position. A modular building that can be delivered to site and which does not require substantial finishing works or large teams to implement installation is a major benefit, as speed of delivery is a critical factor for most projects alongside meeting important new health and safety measures.

Even in projects where it is not possible to fit Eurobrick brick slip cladding to a module before it reaches site, the cladding work can be taken off the critical path which means contact between different teams on-site can be managed more effectively.

A brick finish remains popular and is sometimes required to fit in with existing buildings. Our wide range of brick slips allows you to match the finish of existing structures and as our systems are flexible, they can be used in conjunction with other exterior finishes such as timber and render. This means a mixed palette of finishes, popular for creating a contemporary look, is achievable. And you can be assured that our kiln fired clay brick slips weather and age in the same way as conventional brickwork, requiring little to no maintenance.

Eurobrick have supplied a wide range of projects including residential and leisure developments, schools, colleges and universities throughout the country. Not only are our systems tried and tested, but they have certification from the British Board of Agrément (BBA), are LABC registered and we also provide our own 25 years guarantee.

Not all systems are created equally and while Eurobrick’s products have been tested extensively in laboratories they have also been tested and proven out in the real world during our 30 years in business. Other suppliers offer alternative systems however few, if any, have the wealth of experience and knowledge accumulated by Eurobrick and our dedicated team will be pleased to provide expert advice and practical solutions.

Furthermore, there is a network of independent Eurobrick Approved Installers who can provide experienced labour to projects of all sizes all over the UK.”

Eurobrick’s brick slip cladding offers numerous benefits in many situations. For modular/off-site construction the ease of installation, low weight, product consistency and a means to provide a real clay brick finish are key. While the construction industry is forced to adapt to the current circumstances, modules constructed off-site but with traditional appearance finishes will enable projects to proceed while maintaining the safety of the workforce.

MODULAR BUILDING CAN HELP THE HOSPITAL SHORTAGE

When Wuhan, China, began to first wrestle with the outbreak of COVID-19 and the need for medical centers, it turned to modular construction. In less than two weeks, it was able to create the 1,000-bed Huoshenshan Hospital and the 1,600-bed Leishenshan Hospital. Videos of the construction were shown on YouTube.

As the coronavirus begins to take hold in the U.S., many are wondering whether there will be a similar need here. There’s even talk of turning New York City’s Javits Center into a temporary medical facility. Some cities are repurposing hotels and other facilities to quarantine people or provide support for the homeless.

Error, group does not exist! Check your syntax! (ID: 6)

 

With the demand for hospital facilities set to hit critical mass within the next few weeks, especially in large urban areas, many people are looking to modular construction as a potential solution.

Why modular construction is a good fit for hospitals

Stephen B. Jacobs , FAIA of Stephen B. Jacobs Group, PC , the architect behind the tallest modular hotel in New York City, explains that the ideal projects for modular construction are ones that have a lot of repetition. This means that both nursing homes and hospitals (as well as hotels and apartment buildings) are a natural fit.

Modular construction can be assembled quickly and isn’t dependent on the weather. This means modules, which are built in a factory, can be assembled at any time. Right now, while there are concerns regarding social distancing, putting modules together may require some different practices.

What may slow the process

One issue, however, is making sure modules arrive where people need them most. This becomes especially important when there is an emergency. As Jacobs notes, “The maximum width, length, and height of modular are determined by transportation considerations rather than what is right for the project.”

One of the reasons that China was able to move quickly was that it has access to a lot of inexpensive labor, much of it required to work in round-the-clock shifts. Also, the fact that Wuhan was on lockdown kept the streets free for construction vehicles and the transportation of modules.

Core benefits of modular construction

One of the most important things about modular construction is that it separates the location where the project is constructed and the availability of local labor required to construct the project conventionally. This could also allow factories to build healthcare modules and deploy them as needed.

“Modular construction in many ways simplifies the developer’s task in that it puts a significant portion of the project under a single responsibility,” said Jacobs.

Economics are also a key determination. Modular construction has the potential of achieving major savings in the construction process. We had already identified modular construction as a top trend in 2020 for cost savings and speed, both of which have now become more critical than ever before.

Moving beyond the immediate need for more hospital beds and exam rooms, it may also be possible that design trends may shift away from wide open spaces toward properties with more individual rooms and sections. This could make modular construction even more appealing for the long term.

What does modular construction look like for the long haul?

“For modular construction to take the next leap into fireproof high-rise construction, we require many more local factories with the ability, reliability, and financial structure to produce fireproof modular that are required for multistory buildings,” says Jacobs.

MODULAR STEPS UP TO THE CHALLENGE

Error, group does not exist! Check your syntax! (ID: 6)

More than 1,300 people answered a job advert for carpenters, labourers, joiners and shop fitters to work at Darwin Group, in Shawbury, building emergency hospital units to combat the virus.

From its manufacturing centre, wards for more than 150 new beds will be built using the companies advanced modular design system. The manufacturing centre will be working virtually 24 hours a day seven days a week to get the buildings delivered in the shortest possible time.

The buildings will be going to three NHS trusts in England in the North West, Midlands and Home Counties regions.

The building modules will be transported to the three sites, from the Shropshire manufacturing centre, where the Darwin installation and site completion teams will commission the wards for use. The whole process is expected to take around nine to 10 weeks.

A company spokesman said: “We wouldn’t be able to achieve this without the full support of our manufacturing, site and office staff who have been magnificent in stepping up to this challenge.”

The company said it has also engaged specialist local suppliers to provide a full hot and cold meal service for the workers, as well as a specialist cleaning company to provide “the highest level of cleanliness and sanitisation practical in the workplace”, in an effort to protect staff as far as possible, while still providing an absolutely essential service.

An advert for the jobs on Facebook placed by Shrewsbury recruitment firm Team 4 You yesterday received an unprecedented response, with operations director Nick Lewis revealing they had taken more than 1,390 calls and hundreds of emails.

He said it was a great response and had included all manner of people wanting to help, including one 76-year-old retired carpenter.

Mr Lewis said they would be keeping all the details of the people who had been in contact and would be matching their skills ready for when they need more workers.

The developments come as the government is looking to increase capacity for intensive care units to treat people most seriously affected by coronavirus.

Experience

Yesterday Health Secretary Matt Hancock announced the construction of a 4,000-bed hospital at the ExCel centre in London, with 500 to be ready in a matter of days.

The Darwin Group’s website explains its track record in providing buildings for the NHS, saying: “Darwin Group are one of the UK’s most reliable and trusting providers of modular healthcare buildings, with considerable experience in delivering permanent solutions for a wide range of healthcare needs to clients in both the public and private sector; including ward accommodation, outpatient care and walk in centres.

“Using the latest construction techniques Darwin Group Ltd can deliver outstanding facilities at an exceptionally affordable price in a time scale that suits you. Completing every build with minimum disruption, and maximum infection control to ensure the safety of patients, staff and visitors at all times.”

The firm has a wealth of experience building modular hospital buildings, with its website stating: “Darwin Group have been awarded more than 20 projects through the NHS SBS Modular Buildings Framework over the last 2 years. We have also been awarded places on all five lots applied for on the Crown Commercial Services (CCS) Modular Buildings Framework. Our position on these frameworks is testament to our experience and the quality of construction services we are able to offer.”

The firm also built a 24-bed acute medical unit for Wye Valley NHS Trust at Hereford County Hospital.

FREE UP MMC FINANCE AND BOOST HOUSING

Giulio D’Andrea, marketing director at Green Life Buildings asks: Could MMC be the solution to the UK’s post-coronavirus housing backlog?

 

Error, group does not exist! Check your syntax! (ID: 6)

 

Covid-19 has turned the world upside down. When you don’t what to think any more, you look for wisdom elsewhere: from Shakespeare, from the Bible or from a football manager.

Let’s start by (mis)quoting Bill Shankly, a Liverpool FC coach even greater than Jürgen Klopp: “Some people believe football is a matter of life and death … it is much, much more important than that.” Let’s substitute finance for football. If I asked: “What’s your greatest concern right now?” I’ll bet it wouldn’t be the fiddly process of applying for a mortgage from a British bank or building society. Like most of the world, your worry is how we’re going to overcome the mortal, viral threat we all face.

Unlike the crash of 2008, the problem is the spread of a natural virus, not the international transmission of dodgy, man-made mortgages. Central banks can lessen the economic impact of coronavirus, but they can’t slow its spread, immunise individuals or cure those who catch it.

I don’t pretend to know when society might get back to ‘normal’ or what the new normal will look like. It may be nothing like the past. But let’s take housing and look a few months or years ahead. If construction, like other industries, is forced into unseasonal hibernation, the current housing backlog will grow and the need for new starts and completions will intensify.

What can be done to get MMC financed more seamlessly?

Homes England could hold specific events for lenders and valuers and invite modern methods of construction (MMC) providers to discuss the benefits of their systems over traditional methods.

Homes England should be actively encouraging structural warranty to provide the likes of the National House-Building Council (NHBC) with the technical/admin support to understand the different systems, so the seal of approval can be granted faster.

There is a real opportunity for lenders to finance projects that are only viable by using MMC systems, such as infill sites, or tier two sites, therefore, an individual or department within each lender that specialises in MMC should be considered. Some lenders are already undertaking this.

VAS Panel should have access to a group of valuers that specialise in MMC, who can, therefore, provide lenders with the appropriate information to aid finance applications.

Home England’s development finance fund should consider preferential rates for developers that are willing to adopt MMC on their scheme over traditional.

 

The MMC offering

Overcoming years of hidebound obstruction from builders and developers, MMC — like the advanced building system from Green Life Buildings — is recognised and being promoted by the government. What Green Life Buildings and other MMC firms offer is a way of building smarter, cleaner, warmer and quicker. Good for developers, for buyers, for the environment and for lenders, too. Or so you might think.

Here we come up against the law of unintended consequences; the reverse of Adam Smith’s ‘invisible hand’, where selfish acts benefit all. In this case, official recognition of MMC has led some lenders to create a new MMC loan category. Ticking MMC on a mortgage application form can mean a slow, bureaucratic process that delays rather than accelerates new construction. Since MMC is by nature new, how can a building society surveyor assess local demand for MMC houses in setting a value against which to lend? Catch-22.

It may comfort finance professionals to know they’re not to blame for the crisis. But if mortgage lenders want to help get Britain better housed as we recover from the current crisis, here’s one idea.

If mortgage business is slack in the coming months — as seems likely — why not use the time to review the lending process so that MMC is a plus point for borrowers and not an obstacle to getting a mortgage? And if the government is serious about promoting modern, greener building, it should use its powers as a referee to blow the whistle on lenders who accidentally obstruct MMC.

Guru Bill Shankly had it right.

“The trouble with referees is that they know the rules, but they do not know the game.”

Modern construction needs modern financing. If politicians don’t understand the game, it’s time they learned at least to avoid scoring an own goal.

BUILD GREEN TO BEAT THE HOUSING SHORTAGE

Following the launch of the Building Better, Building Beautiful Commission’s report, the Housing Secretary has said that he wants to see zero-carbon homes being built “as standard” within 5 years. David Hopkins, Director at the Confederation of Timber Industries, argues we have no time to waste and discusses how switching focus to building homes with timber can achieve this now.

 

Error, group does not exist! Check your syntax! (ID: 6)

 

The construction industry is faced with a paradox – charged with building more houses, whilst reducing the amount carbon produced. When looking at the emissions of the industry over the last decade, the trend is worrying – with total emissions from construction climbing rather than falling. Building more resilient, efficient, sustainable and attractive homes is key to addressing this conundrum.

It is certainly true that whilst there are challenges the industry must face up to, there are readily available solutions that can sustainably ease the current, and dire, housing shortage. One of these solutions is increasing the use of Modern Methods of Construction (MMC). MMC use offsite construction methods, and are quicker, cheaper, quieter and more environmentally friendly than traditional onsite methods.

We can make MMC even more sustainable by using them to build with timber. Timber is the most sustainable, effective and attractive construction material available to use, and using it is key to meeting emissions targets. Indeed, one of the key recommendations of the Committee on Climate Change in its recent report UK housing: Fit for the future? is to increase the use of timber in construction.

Currently, only around 22% of homes in England are built using timber frames, with only a slightly higher percentage UK-wide. This represents a significant missed opportunity. If the target additional 270,000 homes per year were built using MMC, homes would not only be built more quickly, but they would boost local economic development, modernise and boost productivity in the construction industry, and help the UK become a world leading low-carbon economy. The Committee on Climate Change calculated that if those 270,000 homes were built out of timber, this would absorb and store three million tonnes of carbon.

The Government can do their bit to help deliver this, by working with industry to ensure procurement contracts are awarded to manufacturers based on their contribution and commitment to low carbon construction. Equally, local authorities could incorporate a preference for using the lowest embodied carbon systems and materials into every council’s planning policy framework. In order to meet the skills requirement needed to build more homes, local governments should introduce a requirement to employ a minimum number of apprentices and provide a minimum level of training into local planning policy frameworks.

These measures would help encourage investment into timber-frame factory development across the country.

Unlike other materials, trees require little more than sunlight and water to grow, and they absorb and store carbon as wood. Timber itself is lightweight, easy to use, and requires very little energy to produce high performance, low carbon buildings. Our own industry life-cycle assessment studies have shown that more carbon is absorbed and stored in timber products than it takes to manufacture them – something no other mainstream material can claim!

The threat to life on this planet from climate change coupled with the need to build good quality housing at scale, quality and economically, should mean building with timber is the solution to many of the problems associated with the housing crisis.

There is no shortage of supply either. Thanks to sustainable management practices across Europe, far more trees are planted than are harvested. This has meant the forests of Europe – the UK’s main source of supply – have expanded by five per cent over the last quarter of a century, at a rate of 700,000 hectares per year.

Growth in the forest has come at the same time as economic and industrial growth in the timber sector, with innovations in engineered timber products meaning we can now see medium rise buildings across our cities all built from timber. Of course, persuading developers to use timber systems has not been easy. Change is difficult in a conservative supply chain. It is a lot easier dealing with what you know and building the next building in the same fashion as the last.

Of course, the Grenfell tragedy, though it was a concrete building, is having an impact because there is a misunderstanding over the performance of engineered timber systems in fire. Unlike many other materials, timber is entirely predictable in fires, and can hold its structure far longer than other frames. When exposed to fire, treated timber will form a charred layer creating its own barrier to burning, meaning that the fire is contained and struggles to spread. Despite these properties, the timber industry knows this is an Achilles heel and has invested heavily in fire testing and safety measures to reassure a sceptical public.

In 2009 what was then the world’s tallest engineered mass timber building was constructed in Murray Grove, Hackney. It was the start of a building revolution with the UK at the forefront. Choosing to build with cross-laminated timber (CLT) meant we could reduce the use of concrete, a material with one of the planet’s largest carbon footprints, for a material which captures carbon and stores it for generations – wood.

The Government, and indeed anyone with influence in this field, should urgently follow the advice of their own reports, and start building with timber for both their own and their children’s future.

NEW GUIDANCE FROM CIRIA

Methodology for quantifying the benefits of offsite construction CIRIA and the Laing O’Rourke Centre for Construction Engineering and Technology, University of Cambridge, are pleased to announce the launch of a new guidance report entitled Methodology for quantifying the benefits of offsite construction (C792). Offsite construction offers the potential to deliver a number of benefits including better quality construction, improved health and safety, a faster construction programme as well as predictability of cost and time on any given project. Despite this, uptake of offsite construction is slow as there is no industry method for assessing the benefits of offsite techniques. This new CIRIA guide proposes a framework for comparing construction approaches, making it possible to keep consistent records across projects and identify all the possible benefits available. This guide also highlights the challenges that can be expected when assessing the performance of construction projects and developing robust benchmarks for comparison. It provides a framework for evaluating project performance that can be used by clients, construction management teams and designers to assess the value and benefits achieved on projects. The guidance is set to support decision making and facilitate wider industry collaboration across different sectors in the construction industry. Professor Lord Robert Mair, Emeritus Sir Kirby Laing Professor of Civil Engineering and Director of Research at the University of Cambridge commented “There is compelling evidence for more widespread adoption of offsite manufacture in construction. Yet a methodology for quantifying its benefits is much needed. The process outlined in this excellent report provides an invaluable guide for industry professionals, such as contractors and project managers, as well as those who are influential in decision-making on construction projects, including clients, advisors and policy makers.”

 

The guide is available to download freely from www.ciria.org/c792.

10,000 NEW MMC HOMES

The West Midlands Combined Authority (WMCA) has signed an agreement within Urban Splash to build 10,000 new homes using Modern Methods of Construction

The WMCA has signed a memorandum of understanding (MOU) with Urban Splash to build 10,000 new homes in the region.

The partnership deal is aimed at helping the WMCA hit targets to deliver 215,000 new homes across the region by 2031, and brownfield regeneration, in order to meet future housing and economic demand.

MOU agreement

The signed MOU outlines that House by Urban Splash will aim to deliver circa 5% of WMCA’s 215,000 new homes target within the region by 2031. A target of 10,000 new multi tenure homes consisting of various ownership models will be delivered across the West Midlands over the 11 year period.

Mayor of the West Midlands Andy Street, said: “The West Midlands economy is continuing to grow at a fast pace and more companies and people are coming here looking to enjoy everything our region has to offer.

“This is of course brilliant news, but it also brings with it a set of challenges, especially in terms of providing enough homes and commercial premises to keep up with demand.

“Urban Splash is one of the most innovative developers in the UK using modern methods of construction that can deliver quality homes at pace on reinvigorated brownfield sites.

“By combining that expertise with WMCA resources, support and expertise we can help meet the housing demand and transform acres of former industrial land into vibrant new communities, protecting our precious greenbelt land in the process.”

Nathan Cornish, group board director at Urban Splash, added: “This partnership brings together investment, understanding and skills to develop brownfield sites, transforming past industrial wasteland into modern-day homes and communities.

“This is further reflective of the current confidence in the regional market and economy – and as the Chancellor noted in his Budget, the commitment at national level to meet the housing demand.

“Urban Splash know the West Midlands well, having delivered iconic projects at Fort Dunlop and Rotunda. We are currently on-site at Port Loop working in partnership with Places for People, Canals and Rivers Trust and Birmingham City Council.

“It is brownfield projects like that we will target in order to bring forward more award-winning homes to the region, delivering architect-designed homes with their own identity, creating vibrant family-focused neighbours.”

Strategic partnership

WMCA and Urban Splash’s ambition is to establish a ground-breaking strategic partnership which brings together public and private sector skills and investment to unlock complex brownfield sites and ease pressure on the greenbelt.

Urban Splash will invest in the acquisition, planning, promotion and delivery of housing development sites and will deliver sustainable communities at ‘scale and pace’.

As part of the partnership deal, Urban Splash will embrace Modern Methods of Construction as its default construction approach, and endeavour to deliver products on brownfield land fit for a region known for its manufacturing excellence.

Urban Splash will also be devoted to making architect-designed homes available to the marketplace across a range of tenures.

The partnership will see WMCA work with House by Urban Splash in order to prioritise brownfield sites to transform into neighbourhoods with distinct characteristics, and that are recognisable and different, each with their own identity.

THE UMBRELLA BRIDGE

The technique works like an umbrella: The bridge is assembled vertically, then lowered and “opened” with hydraulic joints.

By  Derya Özdemir

 

Error, group does not exist! Check your syntax! (ID: 6)

 

Engineers from the Vienna University of Technology (TU Wien) have developed a futuristic twist on building bridges and demonstrated the technique for the first time in Austria last week. The umbrella-like technique resembles the opening and closing of an umbrella over a river.

The traditional way to construct a bridge happens piece by piece: either the engineers make use of scaffolding or use piers to act as vertical load-bearing structures. In order to keep balance, things progress bit by bit, and the bridge is carefully built outwards in any direction.

According to the researchers, this new bridge construction system is expected to be much simpler, faster, cheaper, and has a less environmental impact.

The team had been working on the new method for years: the idea was patented in 2006, in 2010 first tests were carried out by TU Wien. The technique involved hollow girders being mounted to a pier in an upright position. Girders would be joined at the top, and then, would be gently unfolded downwards.

The researchers implemented the new technique for the first time over the Lafnitz River on the border of Austria and Hungary, where Austria’s new S7 motorway is being constructed.

As it was imagined on the paper, the bridge, which is roughly 236 ft long, was assembled vertically instead of horizontally and lowered with bendable hydraulic joints that mimic an umbrella’s internal movements.

You can watch the bridge unfold here:

 

Once the hollow girders were lowered all the way through and horizontal, they could be filled with concrete to complete the structural components of the bridge. According to the team, this technique provides a bridge of the same durability as the traditional methods, while saving a lot of time.

Johann Kollegger of the Institute of Structural Engineering of TU Wien says, “Erecting bridges using scaffolding usually takes months. The elements for the balanced lowering method, on the other hand, can be set up in two to three days, and the lowering process takes around three hours.”

In this case, less time equals fewer costs, and the method could prove extremely useful in areas with uneven terrains or nature reserves that are ought to left undisturbed.

Moreover, it would be much safer for workers since after the umbrella-technique there is only a safe and completed bridge ready to fill in and finish.

If the practice catches on, this might be the future of constructing bridges.
