Sept. 11 led to the boom in supertall skyscrapers

This QUARTZ‘s article about Rethinking cities, could be yet another way of demonstrating that nothing could affect nor alter the development of a town’s built environment. It has, on the contrary, ended up in teaching us the hard lessons of Sept. 11 led to the boom in supertall skyscrapers. It is by Anne Quito, Design and architecture reporter. But despite that Is it Time to Stop Building Skyscrapers? Let us see in any case what it all boils down to.

The hard lessons of Sept. 11 led to the boom in supertall skyscrapers

Cities have to accommodate more people, lessen their environmental footprint, and become more equitable.

Standing tall.

After the Sept. 11 attacks, former New York’s mayor Rudy Giuliani encouraged developers to build low. Like many, he feared Manhattan’s tall buildings would become targets for terrorists, after seeing how swiftly the twin towers crumbled.

Twenty years later, quite the opposite has happened. For better or worse, New York City’s skyline is populated with ever taller and taller skyscrapers, with the highest among them in the heart of the original World Trade Center complex. Nearly all of the city’s supertalls—the term for a structure that rises above 300 meters (984 ft)—were built after 2001. Many of them are luxury condos clustered along 57th Street, two blocks south of Central Park.

Outside New York City, supertalls built after 2001 include the Trump International Hotel and Tower and the St.Regis in Chicago, the Comcast Technology Center in Philadelphia, the Wilshire Grand Center in Los Angeles, and Salesforce Tower in San Francisco. Before Sept 11, there were 20 supertalls in the world. Today, there are more than 200 and several more are in various stages of construction.

How did Americans go from a mistrust of tall buildings to an unprecedented growth in skyscrapers in the US? In a word, science.

It stems from a steely belief in engineering innovation after the attacks, says Carl Galioto, president of the global design and architecture firm HOK. “I think it has to do with confidence,” he says.

Galioto would know. Prior to HOK, he was a partner at the firm Skidmore, Owings & Merril (SOM) and was an architect-of-record for two of the towers that were rebuilt at the World Trade Center complex. Galioto also worked with the US National Institute of Standards and Technology to translate its forensic reports to improving the international building code.

One Vanderbilt, the tallest office tower in midtown Manhattan, opened in Sept 2020.

Changes in building safety regulations after 9/11

Innovations in building safety led to the current boom in supertall buildings, Galioto says. “There is a direct relationship between the developments in building science related to high-rise construction and the perception of improved safety that allowed supertall towers in New York to be commercially viable,” he says.

About 30 safety and security recommendations were added to the building code as a result of the twin tower collapse. They included widening staircases, using thicker glass on the lower levels, using reinforced concrete for a building’s core, installing back-up power systems, and reserving a dedicated elevator for firefighters. There was a greater understanding of “progressive collapse,” when a succession of structures falls like a stack of cards. There was also a renewed appreciation for bollards and the variety of creative forms they could take.

Some of that work included changing the fundamental understanding of safety. Before Sept. 11, building occupants were considered safe when they reached a fire-proof staircase. After learning that more than 200 people perished in the World Trade Center’s elevators, regulations were updated so people were only counted safe only when they reached the ground.

Galioto and his colleagues at SOM used the two towers they designed—One World Trade Center and 7 World Trade—as a kind of showcase for innovations in building safety. Galioto says he has immense trust in skyscrapers. “Not only do I feel confident about working at One World Trade Center, I felt confident enough that my daughters can work there,” he says. “I think it’s the safest building in New York.”

How much did Sept 11 change architecture?

Galioto remembers how the public came up with zany burning-tower escape plans during that time, such as giving parachutes to top floor occupants or designing chains and outriggers to trap wayward plans. “They were somewhere between Jules Verne and Rube Goldberg,” he says. Galioto recalls one proposal that involved installing escape chutes on the side of buildings. “As if people could just slide down 50 stories and pop out of the air like party favors,” he says. “We very quickly realized that people are safer if they don’t jump out of buildings.”

As to whether the Sept. 11 terrorist attack changed the building industry, Galioto says its impact is proportionate. He questions the notion that terrorism is the foremost fear in the mind of architects. “There’s only as much paranoia as there’s a concern for designing for earthquakes or hurricanes,” he says. “If you look at it objectively, it [anti-terrorism concerns] is just another set of design criteria.”

Santiago Calatrava, the widely admired Spanish architect says what happened in New York 20 years ago reverberates through his practice. “The tragic events of September 11th have undoubtedly made an impact on my practice as both an architect and engineer,” says Calatrava, who designed the Oculus transport hub and the soon-to-be-completed St. Nicholas National Shrine at the World Trade Centerin an email to Quartz. “There became new elements to consider in our designs such as building reinforcements, the use of resistant materials, and simply reimagining the flow of a space.”

More ribs: The Oculus at the World Trade Center.

Calatrava explains that he had to modify his original scheme for the Oculus—the bird-shaped building adjacent to the 9/11 Memorial—after the sequence of terrorist events after Sept 11. “Following the terrorist attacks in Madrid in 2004 and London in  2007, the structural design of the Oculus was modified per instructions from the New York Police Department and other responsible authorities to suit newly established security requirements,” he says. “One key change included reinforcing the support structure for the Oculus’ planned ‘wings’ to improve blast resistance. The Oculus had to have twice the number of steel ribs and a column free space was recommended.”

A different line of defense

If engineers have figured out the structure, urban planners say that New York still needs to reckon with the spirit behind building so many gleaming skyscrapers. Vishaan Chakrabarti was the director of the Manhattan office for the New York planning department during the decisive years of the World Trade Center’s reconstruction. In an email, he says engineering sturdy buildings is just half the battle.

Investing in welcoming public spaces is a better plan than creating exclusive “bubbles of security,” as Chakrabarti puts it. He echoes urbanist Jane Jacobs’s theory that a vibrant streetscape is the best form of security. “I wrote back then that using architecture and urbanism as a last line of defense when our national security fails is a mistake, and it continues to be so,” argues Chakrabarti, now the dean of the UC Berkeley College of Environmental Design. “Security was obviously critical after the attacks, but unfortunately we are always fighting the last war.”

AI used to examine construction following earthquakes

An open-source project hosted by the Linux Foundation with support from IBM and Call for Code will use machine learning to help inform quality assurance for construction in emerging nations.

A new open source machine learning tool has been developed to help inform quality assurance for construction in emerging nations.

Build Change, with support from IBM as part of the Call for Code initiative, created the Intelligent Supervision Assistant for Construction (ISAC-SIMO) tool to feedback on specific construction elements such as masonry walls and reinforced concrete columns.

Structural issues

The aim is to help engineers identify structural issues in masonry walls or concrete columns, especially in areas affected by disasters.

Users can choose a building element check and upload a photo from the site to receive a quick assessment.

“ISAC-SIMO has amazing potential to radically improve construction quality and ensure that homes are built or strengthened to a resilient standard, especially in areas affected by earthquakes, windstorms, and climate change,” said Dr Elizabeth Hausler, founder and CEO of Build Change.

“We’ve created a foundation from which the open source community can develop and contribute different models to enable this tool to reach its full potential. The Linux Foundation, building on the support of IBM over these past three years, will help us build this community.”

The ISAC-SIMO project, hosted by the Linux Foundation, was imagined as a solution to help bridge gaps in technical knowledge that were apparent in the field. It packages important construction quality assurance checks into a mobile app.

“ISAC-SIMO has amazing potential to radically improve construction quality and ensure that homes are built or strengthened to a resilient standard, especially in areas affected by earthquakes, windstorms, and climate change”

The app ensures that workmanship issues can be more easily identified by anyone with a phone, instead of solely relying on technical staff. It does this by comparing user-uploaded images against trained models to assess whether the work done is broadly acceptable (go) or not (no go) along with a specific score.

“Due to the pandemic, the project deliverables and target audience have evolved. Rather than sharing information and workflows between separate users within the app, the app has pivoted to provide tools for each user to perform their own checks based on their role and location,” added Daniel Krook, IBM chief technology officer for the Call for Code initiative.

“This has led to a general framework that is well-suited for plugging in models from the open source community, beyond Build Change’s original use case.”

Construction elements

According to Build Change, the project encourages new users to contribute and to deploy the software in new environments around the world. Priorities for short term updates include improvements in user interface, contributions to the image dataset for different construction elements, and support to automatically detect if the perspective of an image is flawed.

Build Change seeks to help save lives in earthquakes and windstorms. Its mission is to prevent housing loss caused by disasters by transforming the systems that regulate, finance, build, and improve houses around the world.

Zaha Hadid: even more than her buildings, it’s her mind that left its mark

Zaha Hadid: even more than her buildings, it’s her mind that left its mark by Lakshmi Priya Rajendran, Anglia Ruskin University is more than an eye-opener on the person behind all those unconventionally looking buildings.

Zaha Hadid: even more than her buildings, it’s her mind that left its mark

In the five years since Zaha Hadid’s passing, much has been written about the glorious and towering legacy the fabled British-Iraqi architect left behind. Thinking about what she started, though, is more instructive.

Born in Baghdad, Iraq in 1950, Hadid – aka the Queen of Curve – fundamentally altered the contours of modern architecture and design. She shattered gender stereotypes too by, in 2004, becoming the first woman to receive the Pritzker prize – the highest award in her field.

As the world grapples with how to respond to the climate crisis, architecture is in the spotlight. The built environment is responsible for almost 36% of global energy consumption. Cement alone causes 8% of global emissions.

In this context, Hadid’s most valuable contribution is the inspiration she represented and the innovation she embodied. She conceived of modernity as an incomplete project, to be tackled. And she demonstrated to students not just how to imagine revolutionary forms but, crucially, how to bring them to life.

Problem solving

The seductive nature of Hadid’s buildings means that the approach she took to sustainability is often overshadowed. It also wasn’t an explicit aspect of her early works, but rather became so later on in her career, in projects including the Bee’ah Headquarters in Sharjah, and Eco-park stadium in London. In 2015 she memorably highlighted sustainability as a defining challenge of her generation and stated that “architects had solutions”.

Hadid was a problem solver. From the outset she was unique in harnessing both technology and talent, through her groundbreaking interdisciplinary research group. She was one of the early adopters of a fully digitised 3D design process. When virtual reality became a thing, her practice was one of the first to adopt that too.

This ability to make things happen was hard won. As a student at the Architectural Association in London in the mid-1970s, Hadid turned heads from the start with her otherworldly ideas. But it took her over a decade to get her designs realised. It was with her first big commission – the 1993 Vitra Fire Station in Germany – that the world finally got to see up close the power of her architectural imagination.

The Danish architect Bjarke Ingels (founder of Bjarke Ingels Group, one of the most dynamic contemporary architectural practices) described visiting Vitra Fire Station as an “eyeopening experience” that brought to life the kind of visual impossibilities people usually only dream of. For all its ambition, though, the Vitra building was criticised as unsuitable by the firemen who occupied it.

Undeterred, Hadid went on to create daring, experimental designs for London’s Millennium Dome exhibition spaces and the Serpentine Gallery’s annual summer pavillion. She gave Innsbruck a new landmark – the Bergisel Ski Jump – and became the first woman to ever design an American art museum, with her iconic Rosenthal Center for Contemporary Art in Cincinnati.

Immeasurable influence

Although her career had begun with that infamous tag of her buildings being unbuildable, Hadid rapidly established herself as a radical architect by creating a strong and unique design statement globally. Hadid expanded her global brand and her reach to product design, fashion and jewellery.

In Canadian architectural historian Despina Stratigakos’s book, Where Are the Women Architects?, Hadid explained how she survived and fought sexism in her profession. Her inspiring attitude and professional demeanour was gender-neutral. She was able to switch between femininity and masculinity as required to survive and excel in what is a ruthless and ultra-competitive business.

In this way, even though her projects saw her labelled a starchitect, Hadid’s ideas set her apart from the old school. They opened a radically new path for later generations, like this year’s Pritzker laureates, Anne Lacaton and Jean-Philippe Vassal.

Her presence continues to be felt across the contemporary design and architecture worlds. With around 1.2 million Instagram followers, Zaha Hadid Architects is now the most followed architectural practice in the world. Her sinuous lines and captivating shapes have been referenced by set designers on trendsetting movies including Black Panther.

Her words – especially the famous quote, “There are 360 degrees. Why stick to one?” – have stuck with architects in China and designers in Germany and India. Her principles have fostered new possiblities in architectural research, thinking and process.

In every way, Hadid remains a muse. She was rebellious and defiant. She embraced the unimaginable. Known for provoking controversies, even her critics agreed to the fact that without Hadid, architecture would be less interesting.

When she won the Pritzker prize in 2004, the jury noted how consistently she defied convention. Even if she’d never built anything, they said, Zaha Hadid would have radically expanded the possibilities of architecture. She was lauded as an iconoclast, a beautiful mind. As the critic Joseph Giovannini put it at the time, “Rarely has an architect so radically changed and inspired the field”.

Debunking Construction Integration Technology Myths

Advertisements

Advanced Project Management & System Integration Project Management & System Integration elaborated on the current trends in the construction industry concerning its necessary but vital digitalisation. They came up with what is so apparent, i.e. deconstruct that heavy concrete slab of traditions and day-to-day routines that weighs on the industry. It is all about debunking Construction integration technology myths because Digital integration would otherwise be inefficient.

March 26, 2021

Few construction industry leaders would say they oppose data integration. Most acknowledge that combining different data types and formats into a central location allows access to complete, current and accurate information to help them make fact-based decisions instead of acting on hunches. So why doesn’t every engineering and construction (E&C) firm have a warehouse of integrated data? The culprit is often misinformation created by myths about data integration. We will debunk three of the biggest myths about costs, downtime, and complexity below.


Myth #1: Data integration cannot be achieved without high costs

This myth was once true, and some vendors still do quote integration approaches that are not feasible for many E&C firm budgets. But today, integration solutions once available only to enterprises atop the ENR 500 are now available to small and mid-sized firms. Recent breakthroughs in virtualization, iPaaS, and cloud computing have contributed to their lower costs and broader availability.

Virtualization

As defined by Tech Target, data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details, like data format or its physical location. As this technology has matured, it has driven total integration costs down.

Integration Platform as a Solution (iPaaS)

Gartner defines iPaaS as a suite of cloud services enabling development, execution, and governance of integration flows connecting any combination of on-prem and cloud-based processes, services, applications, and data within individual or across multiple organizations.

iPaaS is ideal for E&C firms. Collaborating and sharing information across multidisciplinary teams including owners, architects, consultants, engineers, contractors, subcontractors, and suppliers using different systems is the cornerstone of E&C work.

Construction organizations typically collaborate with teams across multiple cloud platforms, so when considering iPaaS, look for a cloud-agnostic solution. Some solutions offer packages with varying costs based on the number and/or complexity of flows (data sources) needed. Custom email alerts may also prove helpful, for example, if an error occurs or if a batch is completed.

Cloud Computing

Collecting servers in a single room or rack is no longer necessary. Geographic isolation of data sources is actually a business continuity / disaster recovery best practice. Amazon Web Services, Microsoft Azure, and Google Cloud were growing in popularity even prior to the COVID-19 pandemic. The sharp increase of remote work and video conferencing accelerated their growth.

E&C firms are deploying more hybrid-cloud and multi-cloud arrangements. Essentially, hybrid cloud refers to the combination of private and public cloud infrastructure, and some or many from an organization’s own data center. Multi-cloud configurations use multiple cloud providers to meet different technical or business requirements. The reason cloud computing, sometimes referred to as infrastructure as a service (IaaS), is so popular is that it allows for fast scalability, broad availability, and low total cost of ownership vs. managing everything in company-owned data centers.


Myth #2: Data integration requires significant downtime

Even during off-peak times, E&C firms want to avoid downtime. Today’s data integration solutions offer rapid time to value with development-cycle times reduced by as much as 33%. Some solutions may be able to eliminate workday downtime with only brief downtime on evenings and weekends.

Containerization, enabling developers to create predictable environments isolated from other applications, is also used by some solutions. With containerization, consistency is guaranteed regardless of where an application is deployed. Containers only use about 60 lines of code so they can be developed and deployed quickly to minimize downtime.


Myth #3: Managing a data warehouse is complicated

What is involved with keeping a data integration platform running?

The short answer is that it depends, but there are solutions that do not require a high degree of information technology (IT) overhead. Look for solutions that include intuitive dashboards to monitor and troubleshoot integrations, the ability to quickly review flows, rerun flows on demand, or view error details, if any.

If using iPaaS, consider a solution that includes a dedicated client-success (CS) manager. The CS manager puts an iPaaS subject-matter expert on your company team, instantly adding value while eliminating the learning curve for an existing team member to become proficient. And unlike a consulting relationship where the expert stays for a while to train your team but then leaves, a client-success manager is always available to create or troubleshoot flows.

Today’s construction and engineering world requires unprecedented external collaboration, with multiple parties outside your organization at every building, site, and external site. The mobile information, in turn, reduces data centralization, creating a greater urgency to adopt a data integration solution.

From amazing abodes to centres of care and hard-working offices, we chart some of the world’s best examples of sustainable architecture, buildings that not only look good but also do good. Here is sustainable architecture in innovative and inspiring building design throughout the world as brilliantly covered in this pictures and text article.

The picture above is of the Elephant Museum.

Sustainable architecture: innovative and inspiring building design

Elephant World by Bangkok Project Studio

Elephant World’s architecture nods to both human and elephant needs, showcasing a strong sense of social sustainability but a respect to the environment too. The Wallpaper* Design Awards 2021 Best Sanctuary winner is a design by Thai architect Boonserm Premthada and his practice, Bangkok Project Studio. Premthada worked with local labour and materials to create a complex dedicated to the wellbeing of humans and animals, including an observation tower, a museum and a multifunctional event space. The design blends with the landscape and uses natural materials. For example, the bricks used for the museum were created on-site by local workers using loam found in the area. bangkokprojectstudio.co

Powerhouse Telemark by Snøhetta

This ultra-sustainable workspace is a building that actually creates more energy than it will consume over its entire lifespan. Architecture studio Snøhetta, together with collaborators R8 Property, Skanska and Asplan Viak, has recently completed the project, Powerhouse Telemark, the fourth energy-positive building in its Powerhouse portfolio. Located in the city of Porsgrunn, the project creates much needed office space. It features solar panels on its roof; natural shading is promoted, while plentiful insulation ensures heat is retained where possible; and heat is stored in the building elements, to be released slowly, while a geothermal well supports heating and cooling. As a result, Powerhouse Telemark was awarded a BREEAM Excellent certification. snohetta.com

Anandaloy by Studio Anna Heringer 

German architect Anna Heringer’s Anandaloy project in rural Bangladesh is a successful example of sustainable architecture, both in terms of social and environmental responsibility. The community centre and textile workshop in rural Bangladesh contains a therapy hub for people with disabilities on the ground floor and a fair-trade textile manufacturing workshop for local women on the first floor. Made out of rammed earth and bamboo, the structure explores age-old local building techniques and materials in soft curves and textures that connect with its place and the region’s vernacular. The building recently scooped the prestigious. Obel Award for 2020anna-heringer.com

Treehouse by Olson Kundig

US architect Tom Kundig, of Seattle practice Olson Kundig, is behind this sustainable teak holiday house in Costa Rica. Called the Treehouse, the private home is built predominantly out of locally harvested teak, and is open to the elements. This makes sense for Kundig’s clients for two reasons: as avid surfers, it gives them a chic version of a basic surfer’s hut; and as environmentalists, their new home ticks a number of sustainability boxes. Spanning three floors, the building is designed to operate passively, and slatted panels keep it open to the outdoors. ‘Our aim was to create a home that is very leaky to the view and light and air,’ says architect Tom Kundig. The structure also has its own rainwater collection system. olsonkundig.com

Bahareya Village by ECOnsult

Egyptian architect Sarah El Battouty, head of local studio ECOnsult, led the sustainable design of Bahareya Village, an eco-friendly compound for farm workers in the country’s Western Desert. Created to be home to the farming community engaged by organic tea producer Royal Herbs, the complex uses gravel manufactured from recycled construction waste for the base of its minimalist concrete structures. Cacti scattered throughout the campus offer splashes of greenery without compromising on a commitment to water efficiency. And a technique El Battouty borrowed from desert communities – raising the foundations of the buildings to create distance between the floor and therefore the rising heat from the land – reduces indoor temperatures by eight to ten degrees. econsultarch.com

This minimalist and highly eco-friendly house overlooking the Hudson River Valley is the country home of New York-based Alloy’s principal, architect and developer Jared Della Valle. Named Cold Spring Residence, the house sits on the land as lightly as possible. Della Valle worked with passive house sustainability standards to create his retreat, including solar panels for year-round energy, a well-insulated building envelope and careful management of the site’s water resources. The building is also partly sunken and cannot be seen from the street, aligning with its creator’s desire for a ‘a degree of modesty’, so that the architecture doesn’t compete with the striking surrounding natural landscape. alloyllc.com

Copper Hill by BIG

The Amager Resource Center in Copenhagen, also known as Copenhill, is one of the city’s latest initiatives that put climate action to the forefront. Designed by the Bjarke Ingels Group (BIG), the building is essentially a rubbish burner; yet it’s also so much more than that. The structure houses an artificial ski slope, recreational hiking area and climbing wall on top of the waste-to-energy plant. Built using aluminium blocks, this piece of infrastructure aims to treat 400,000 tonnes of waste annually. The result is supplying 150,000 Danish households with district heating and 70,000 with electricity from non-recyclable waste. big.dk

Flying House by Martand Khosla

Created by architect Martand Khosla for a Delhi-based family of four, this weekend retreat in India’s Dharamshala is rooted in traditional materials and techniques. Set between farmland and a lush forest on the Dhauladhar mountain ranges of the Himalayas, Flying House has been built using local resources – stone, stabilised mud brick, slate and pine. A lot of the earth and stone dug out from the site during the foundation excavation went back into the construction. Building site wastage was minimised and a lot was recycled, making this house quite literally of its place. The construction uses stabilised mud brick, a method local workers were taught, using equipment from Development Alternatives (a social enterprise for sustainable solutions in India). This way, not only would the local stonemasons be able to build this particular house, but they would be able to master the craft and continue using it in the future. rk-ds.com
