Caltech's new Resnick Sustainability Center gets scientific from the outside in

2024-11-13T16:58:00-05:00

Caltech’s new Resnick Sustainability Center (RSC) has opened after the completion of an 80,000-square-foot design produced by the LA-based Yazdani Studio of CannonDesign.

The project, which had been marketed as an interdisciplinary and cohesive "makerspace" for Caltech scientists and engineering students, stands out thanks to an innovative building envelope shaped by an "undulating glass skim" that's noticeably distinct from other academic buildings on campus.

A language of diagonal sunscreen frits covering a low-E coated glass curtain wall and its supporting mass timber "gridshell" in the facade contribute to the building's impugned profile against the presence of the aforementioned older structures. The use of timber as a structural and aesthetic component also blends the atrium and walkways with a concrete shell core housing suites of research laboratories and academic spaces to make an elaborate yet wholly scientific composition from the outside i...

Engineers develop bone-inspired concrete for stronger structures

2024-09-19T13:33:00-04:00

Inspired by the natural architecture of human bone, engineers at Princeton University have developed a new cement-based material that significantly enhances the toughness of traditional concrete. This innovative material resists cracking and sudden failure, making it a promising solution for more durable and long-lasting architectural structures.

The research, led by Professor Reza Moini and Ph.D. candidate Shashank Gupta from Princeton's Department of Civil and Environmental Engineering, was published in Advanced Materials. The study introduces a unique design that incorporates cylindrical and elliptical tubes within the cement paste. Mimicking the structure of bone, specifically the tubular osteons found in human cortical bone, this design allows the concrete to trap and delay crack propagation. This “stepwise cracking” mechanism absorbs more energy, reducing the likelihood of sudden collapse.

1 in 3 American bridges are in need of significant repairs, new study finds

2024-09-16T11:49:00-04:00

The American Road & Transportation Builders Association’s 2024 Bridge Report survey has found 221,800 bridges in need of repair and 76,175 bridges that should be replaced across the country. The accounting, released in late August, claims that some 36%—or nearly 221,800 spans—require some repair work currently. States are simply not committing enough of their available bridge formula funds from the 2021 Infrastructure Investment and Jobs Act to adequately solve the repair problems, according to their analysis.

The report echoes the urgency of last year’s findings, which declared the exact same percentage of bridges to be "structurally deficient", requiring a total of $319 billion worth of repairs nationwide.

Maryland officials announce design contract for collapsed Francis Scott Key Bridge reconstruction

2024-09-07T12:00:00-04:00

The Maryland Department of Transportation has awarded the contract to rebuild the collapsed Francis Scott Key Bridge to Kiewit, a national infrastructure development firm with extensive experience in similar projects and a reported $17.1 billion in revenues last year. The AP reports the design contract is worth $73 million. Officials released the RFP in June following the March 26th disaster and will grant "exclusive rights" to the company for its second construction phase, which is expected to stretch into 2028. The total cost of reconstruction is expected to surpass $1.7 billion.

Grimshaw's new pedestrian bridge opens in Toulouse

2024-07-09T15:35:00-04:00

The Grimshaw-designed Robert Poujade pedestrian bridge in Toulouse has officially opened.

Developed alongside ppa.architecture as part of a consortium led by French civil engineering construction company Eiffage, which included Ingérop, ATP, and Quartiers Lumières, the bridge is one of four that will connect the Île du Ramier and the city. It will provide accessible routes through Toulouse’s new “green lung” on the Garonne River.

The approximately 525-foot-long bridge will link the city’s Fer à Cheval district to the north of the island. On the city side, it is connected to the riverbank, with access to the river promenade and cycle path. It is also connected to the Avenue du Mu...

China is planning the world’s largest particle collider to rival CERN

2024-06-26T17:18:00-04:00

China’s plan to construct what would be the world’s new largest particle collider, pending major funding hurdles, is becoming more clear after a technical design report was submitted for the estimated $5.2 billion project. The 100-kilometer Circular Electron Positron Collider (CEPC) is meant to rival CERN’s plans for the Future Circular Collider (FCC) in Europe and would require only three years to complete following its potential commencement in 2027.

Scientific American informs us: “Many of the components that are planned for China’s mega machine are already being tested at other facilities in the country [...] Given that China is already home to a collider that is similar to the CEPC — the Beijing Electron Positron Collider — [and] IHEP might now have more expertise in this area than does CERN.”

Autodesk donates $5 million to help fund Howard University's Design and Make lab

Lizard tails are effective at producing building collapse prevention strategies, Spanish scientists find

2024-05-20T19:30:00-04:00

A group of researchers from the Polytechnic University of Valencia say they have discovered a means for protecting buildings from structural collapse. In a new set of building science experiments conducted in June 2023, they carefully studied animal neurobiology.

El País tells us: “The team of scientists and engineers has devised a hierarchy-based collapse isolation system, the key to which lies in the implementation of structural fuses, which allow the building to be segmented in the event of a failure. According to Adam, this design philosophy is similar to fuse-based protection of electrical networks. His technique has been validated by a test on a real building — 15 by 12 meters in plan, with two 2.6-meter-high floors — using prefabricated reinforced concrete. It is the first solution of its kind to be tested and verified at full scale.”

The Endure project recently made the cover of the journal Nature. Engineering professor Antoni Cladera (who did not participate in the study) t...

For World Engineering Day, these six bridges stand as examples of the complexities underneath every design

2024-03-04T20:06:00-05:00

Today is World Engineering Day, and to celebrate it, Archinect has curated a few outstanding bridge projects we’ve included in our recent news coverage to highlight critical pieces of infrastructure at an important time for civil and structural engineering in the Americas and abroad.

The six highlighted bridges provide examples of remarkable design standards and engineering practices while, in some instances, setting records and starting off new precedents for incorporating alternative materials, the conditions of a circular economy, aesthetic variance, building science, low-carbon construction methods, and more.

World's longest suspension bridge is moving forward in Italy after decades of pushback and delays

2024-02-25T08:00:00-05:00

Construction of what would be the world's longest suspension bridge, connecting Sicily and mainland Italy over the Strait of Messina, could begin this year after the final design recently gained approval. The long-delayed project would stretch more than 10,800 feet if completed.

The controversial bridge is estimated to cost approximately $5 billion and take around seven years to build. It will feature three vehicle lanes and a central lane for rail. The structure is also designed to withstand 180-mile-per-hour winds and up to 7.1-magnitude earthquakes.

The concept has been in the works since the 1960s, and it wasn’t until 2003 that a preliminary design for it was approved. Since then, the project has experienced a cycle of being shelved and revived by various Italian governments in power. Critics of the endeavor have asserted that the bridge has been nothing more than a tool to win votes that would waste billions of dollars.

Production begins on the world’s tallest 3D printed structure

2024-02-16T11:40:00-05:00

Production has begun on a 3D printed tower in Switzerland, which is expected to be the tallest structure of its kind in the world. Named the ‘Tor Alva’ or ‘White Tower,’ the project is currently being fabricated at ETH Zurich, where the first eight columns of the tower’s lower floor commenced 3D printing in February.

Image credit: Hansmeyer/Dillenburger

The columns’ fabrication sees a robot extrude the concrete in 8mm-high layered print paths. In a departure from traditional concrete construction, the 3D printing process means formwork is no longer required, freeing new avenues for the team to experiment with shapes, surface details, and cavities. The tower will also be the first instance of printed concrete being used in a fully structural manner, with steel reinforcement inserted during the robotic production process.

The tower will be constructed in the remote Swiss Alps village of Mulegns, where it will host music and theater performances. At 98 feet (nea...

Thornton Tomasetti CEO and co-founder of Charlie Thornton passes away at 83

2024-01-05T14:20:00-05:00

Charlie Thornton, the well-admired structural engineer, co-founder and CEO of Thornton Tomasetti, passed away in early December at the age of 83, according to his firm.

The Bronx-born Thornton began his career in the New York offices of Lev Zetlin Associates before pursuing a new venture with Richard Tomasetti after 1977. What followed was a long and decorated career in building, with the world’s first supertall designs — Malaysia’s Petronas Towers and the Taipei 101 in Taiwan — among the signature projects in a globe-spanning portfolio that would later include One Liberty Place in Philadelphia, the forthcoming Jeddah Tower in Saudi Arabia, and the delivery of new Yankee Stadium in his hometown.

“Charlie was a visionary, foreseeing the needs of structural engineering, our clients, the building industry and the public it serves,” Tomasetti said in a firm statement. “He was equally dedicated to mentoring everyone in our firm, our partners, and future generations through his founding...

36% of all U.S. bridges are structurally deficient, study finds

2023-08-29T13:49:00-04:00

A study of every bridge in the U.S. Department of Transportation database has discovered a need for $319 billion worth of major repairs or replacement work on a total of 222,000 spans across the country.

The findings published in the American Road & Transportation Builders Association’s 2023 analysis also showed an overall decline of 560 bridges in need of repair versus last year. The news comes a little less than two years removed from the belabored passage of the $1 trillion Infrastructure Investment and Jobs Act, a piece of legislation that included no less than $40 billion for bridge projects through the end of 2027.

Construction Dive has more analysis of the new report, which showed an increase in the overall share of bridges that are in "fair" condition simultaneous to a decline of those in both "poor" and "good" categories.

Coffee grounds can make concrete a little stronger, too, according to a new RMIT study

2023-08-28T11:58:00-04:00

Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a "double shot" at life and reduce waste going to landfills. [...] Published in the Journal of Cleaner Production, the study by RMIT engineers is the first to prove that waste coffee grounds can be used to improve concrete.

The study found that three different coffee ground samples each increased their concrete pour’s compressive strengths by up to 30% once their organic compounds were broken down through pyrolysis. The discovery could go a long way in combatting issues such as food waste and the carbon impact of concrete’s still rampant use as a construction material worldwide. RMIT will follow up with additional mechanical and durability tests on the same samples.

"Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill," the paper’s co-lead author, Dr. Shannon Kilmartin-Lynch, explained. Discarded PPE may also have a stirring second life in construction, according to a separate study the same team of researchers published last year.

MIT team tests open-source cooling chamber using 75% less energy than refrigerated cold rooms

2023-07-27T11:18:00-04:00

MIT researchers have published details of a new open-source forced-air evaporative cooling chamber. Described as being less expensive than refrigerated cold rooms, the chamber is intended to offer accessible cold storage for smallholder farmers, as well as significantly reduce post-harvest waste in hot and dry climates.

The chamber, which can be housed in a used shipping container and powered by either grid electricity or solar panels, has a capacity of 168 produce crates. The design uses industrial fans to draw in hot, dry air, which is passed through a porous wet pad. This creates cool, humid air that is directed through crates of produce, allowing rapid cooling. The air is then directed through the raised floor and to a channel between the insulation and the exterior container wall, where it flows to the exhaust holes near the top of the side walls.

The project was led by MIT Professor Leon Glicksman of the Building Technology Program within the Department of Architecture and Res...

This Earth Day, watch PBS’ new highlight of early solar pioneer Mária Telkes

2023-04-21T16:46:00-04:00

For nearly 50 years, chemical engineer and inventor Mária Telkes applied her prodigious intellect to harnessing the power of the sun. She designed and built the world’s first successfully solar-heated modern residence and identified a promising new chemical that, for the first time, could store solar heat like a battery. And yet, along the way, she was undercut and thwarted by her boss and colleagues — all men — at MIT.

The Hungarian-born scientist developed more than 20 patents in her lifetime and aided Eleanor Raymond on the development of the Dover Sun House in 1948.

University of Seville architecture professor develops new mathematical concept that can impact 'engineering and construction of buildings'

2023-03-20T09:10:00-04:00

During the construction of the university’s new engineering building, Cabeza-Lainez found that calculating the area of a roof with straight lines resting on a semicircle was impossible just by using pi. After 30 years of research, [he] published a paper about his discovery in ScienceDirect [...] Both articles present his proposal of a number psi (Ψ), with a value of 3.140923, close to pi but which can be applied to a versatile geometric form that he calls an antisphere.

According to El Pais, mathematician and architect Dr. Cabeza-Lainez had to develop his own proprietary calculation software in order to prove the equation. He has also published a book on solar light transfer and says the application of psi in various forms can lower costs associated with energy consumption by 50%.

Graphical Abstract of research from "New Simulation Tool for Architectural Design in the Realm of Solar Radiative Transfer" paper by Joseph Cabeza-Lainez, Jose-Manuel Almodóvar-Melendo, Paula Revenga-Dominguez, Inmaculada Rodríguez-Cunill, and Yingying Xu. Published research can be found in MDPI Journal's Special Issue "Sustainable Design in Building and Urban Environment."

He shares with Raúl Limón of El Pais that the new equation can be applied to “a downspout, to a network of pipes, to an earthquake-resistant tower, to 150-foot [50-meter] ships without using columns, even to biotechnological devices” that he's tested through models made with 3D printers.

The U.S. is about to begin the largest dam removal project in history

2023-03-16T09:00:00-04:00

Preconstruction work is underway on the largest dam removal and river restoration project in U.S. history. The $450 million project will take out four hydroelectric dams on the Klamath River in Oregon and California to restore habitat and passage for migrating fish. Removal work will begin this summer, starting with Copco 2, which should be gone by this fall, according to ABC 12. The other three dams — Copco 1, the Iron Gate Dam and the JC Boyle Dam — will be removed by the end of 2024.

The projects were approved late last fall in the interest of protecting the local salmon population and other wildlife in the region. Local tribes will plant 19 billion seeds in the wake of the removals in order to boost the region's ecosystems, according to local public radio.

The removals are among the $3 billion worth of dam projects being funded under the new Infrastructure Investment and Jobs Act, though experts still say it isn’t enough to address the 15,600 dams across the country that are currently classified as “high-hazard potential structures” by the American Society of Civil Engineers in 2021.

Atkins joins NEOM as strategic partner for The Line project

The Leaning Tower of Pisa is still straightening things out (a bit)

2023-01-05T12:16:00-05:00

Results from the Leaning Tower of Pisa’s annual checkup are in, as of November 30. After a stabilization project, begun in 1990, reduced the quirky monument’s dangerous lean by a full 15 inches, the tower has straightened itself out by an additional 1.6 inches since 2001. Some Italian officials are taking that optimism further, claiming the Tower could stand all the way straight on its own some day.

This is the second update to the engineering project since 2018. The tower is expected to last at least another 300 years. In a statement to the press, the Italian heritage group Opera Primaziale Pisana said the nearly 850-year-old monument's overall health was "excellent."

Repeated attempts of tourists to correct the lean themselves still appear not to be having any effects.

The American Society of Civil Engineers gives New York's infrastructure a C grade in new report

2022-07-26T09:00:00-04:00

The New York State Council of the American Society of Civil Engineers (ASCE) has released its 2022 Report Card for New York Infrastructure, issuing the state's infrastructure an overall grade of C.

The rating is a slight improvement from its 2015 grade of C-. However, as detailed by the ASCE, a C rating indicates infrastructure that is mediocre and requires attention. The overall grade is the average of ratings across 11 infrastructure categories, from wastewater to transit. For New York, only two infrastructure categories are in good condition, six are in mediocre condition, and three are in poor condition. The state’s highest ratings were in the Public Parks and Solid Waste categories, which each received a B-, while Roads, Transit, and Wastewater received the lowest grades with D+’s.

The ASCE has made suggestions for improving New York’s infrastructure grade, including establishing more long-term funding, creating infrastructure goals that fit new lifestyles and commuting pattern...

China is building a massive new hydroelectric dam with AI-controlled robots and 3D printing technology

2022-05-11T15:37:00-04:00

China is using artificial intelligence to effectively turn a dam project on the Tibetan Plateau into the world’s largest 3D printer, according to scientists involved in the project. The 180 metre (590 feet) high Yangqu hydropower plant will be built slice by slice – using unmanned excavators, trucks, bulldozers, pavers and rollers, all controlled by AI – in the same additive manufacturing process used in 3D printing.

The Yangqu dam project is set to finish in two years and is being overseen by Tsinghua University’s Liu Tianyun, who recently argued that developments in 3D printing have made the technology “identical to nature.”

Its purported future annual output of nearly 5 billion kilowatt hours of electricity for Henan Province is a full billion more than that of the Hoover Dam, whose WPA-era construction was similarly the product of two decades worth of advancements in engineering and construction technologies.

The world's longest suspension bridge officially opens in Turkey

2022-03-21T15:11:00-04:00

Turkish president Recep Tayyip Erdogan opened the 1915 Çanakkale Bridge over the Dardanelles Strait on Friday (18 March). It has a central span of 2,023m, which means it usurps the title of world’s longest suspension bridge from the Akashi Kaikyo crossing in Kobe, Japan.

As reported by Global Construction Review, the new bridge cost €2.5 billion ($2.76 billion) to construct and is expected to generate €5.3 billion ($5.84 billion) in economic output, creating 118,000 jobs and €2.4 billion ($2.65 billion) in revenue. Named after an Ottoman naval victory during WWI, it is the first fixed crossing over the Dardanelles Strait and the sixth one across the Turkish Straits. The bridge is the centerpiece of a planned 321-kilometer-long (200-mile-long), $2.8 billion project to connect motorways in Thrace and Anatolia.

The bridge was designed by Denmark-based Cowi and Pyunghwa Engineering Consultants of South Korea. Arup and Aas-Jakobsen worked on the project as Independent Design Verifier (IDV), with Turkey’s Tekfen and T-ingénierie of Switzerland serving as administrative consultants. The construction was carried out via a public-private partnership, formed in 2017, between a group of Turkish and South Korean companies, led by Daelim, SK, Limak, and Yapi Me...

What does it take to become a facade designer? Brooklyn-based specialist MW-Skins provides some answers

Poorly designed, even for the 1970s

2021-08-29T13:14:00-04:00

The Champlain Towers South design violated building codes at the time of original construction. On the northern side, under the portion of the tower that collapsed, the columns were too narrow to accommodate all of the vertical and horizontal rebar called for in the plans while maintaining clearance required by the code. The pool deck had narrow columns and inadequate load bearing capacity, engineers consulted by the Herald found. Only columns beneath the surviving structure were fully compliant

A team consisting of Sarah Blaskey, Aaron Leibowitz and Ben Conarck worked with four engineers and a general contractor to analyze the "Anatomy of Collapse" and explain the failure of the Champlain Towers South in Surfside, FL. One key factor in the collapse appears to have been "punching shear" failure in the first-floor slab.
