Chopping down tall timber
UK implements a flammable cladding ban, but hits timber too
In Aarhus, Denmark’s second largest city, a consortium of architects, engineers, and manufacturers are advancing the capabilities of concrete construction formwork and advanced design. This effort culminated in a recently unveiled 19-ton prototype dubbed Experiment R.
The project, led by the Aarhus School of Architecture, Odico Formwork Robotics, Aarhus Tech, concrete manufacturer Hi-Con, and Søren Jensen Consulting Engineers, tackles the waste associated with concrete formwork through the use of a novel robotic fabrication method.
How does this new method work and why is it potentially so disruptive? According to the Aarhus School of Architecture, formwork is easily the most expensive aspect of concrete construction, making up to three-quarters of the total cost of a concrete project. Significantly reducing waste associated with the formwork process and the molds themselves boosts environmental performance and the economic feasibility of complex concrete geometries.
The project's new apparatus consists of a heated and electrically powered wire rotating at a speed of approximately 160 feet per second around a carbon fiber frame. This device is mounted atop a robotic arm, which can shape complex detailing. While a polystyrene mold was used for the formwork of Experiment R, the mechanism has the capacity to cut through harder materials such as stone and timber.
Conventional methods of formwork fabrication are significantly more laborious—a typical CNC milling machine is able to process an 11-square-foot surface in approximately three to five hours. In an action that Asbjørn Søndergaard, chief technology officer of Odico Formwork Robotics, refers to as “detailing the whole formwork in one sweep,” the new technology is able to process that same surface area in 15 seconds. Strikingly, this timescale is applicable to both straightforward and advanced design formwork.The 19-ton Experiment B prototype, installed adjacent to Aarhus's Marselisborg Lystbådehavn in July 2018, is an extreme example of what can be achieved with this new method, displaying future possibilities of construction. According to Søndergaard, it is the hope of the consortium that the highly optimized concrete formwork is translatable and ultimately adopted for everyday projects such as minor infrastructural works and standard residential or commercial development.
Grounds for Democracy
It’s high time to memorialize the South’s history of lynching
“If he invited me to a public hanging, I’d be on the front row.”After a video of the moment went viral on Twitter, her challenger, Espy, called the remark “tone deaf.” The incumbent senator is defending it now as “an exaggerated expression of regard,” claiming it was taken out of context. She'll face Espy in a debate tonight without outside press or an audience present, reported the Jackson Free Press earlier today. Hyde-Smith’s poor choice of words, whether meant as a joke or not, represents the irreverent and ignorant way many Americans look back on the horrific lynchings that took place in the Jim Crow South. What makes this even more deeply inappropriate is that Hyde-Smith said this in her native Mississippi, the state that notoriously conducted the most amount of public hangings on record. President Trump is set to a hold rally in support of Hyde-Smith next Monday ahead of Tuesday’s election, but Democrats appear to be reinvigorated and could pull off another upset in the South. While we as a country have worked to acknowledge our harsh history of racial tension and inequality through monuments and museums dedicated to slavery, black culture, and the civil rights movement, we’ve barely begun to take the much-needed step toward memorializing the thousands of victims tortured, murdered, and hung in 12 U.S. states from 1877 to 1950. According to a new report by The Cultural Landscape Foundation (TCLF) entitled, Landslide 2018: Grounds for Democracy, numerous lynching sites in Shelby County, Tennessee, are virtually unmarked for their historical significance. Walking by these nondescript places, no one would know that hundreds of spectators once gathered there in carnival-like fashion to witness these unforgivable acts of racial terror. TCLF makes its case for the recognition of these places by digging into the lynchings of four African Americans in and around Memphis: Mississippi-laborer Lee Walker who was arrested and hung in 1983 for looking like a man who allegedly tried to sexually assault two white women; People’s Grocery owner Thomas Moss, and his employees Will Stewart and Calvin McDowell who all suffered fateful deaths in 1892 because a white grocer nearby instigated a rumor that the Stewart had injured him; cotton farmer Jesse Lee Bond who was shot, castrated, and drowned in 1939 because he asked for a receipt at a store; and woodcutter Ell Persons who was lynched and burned in 1917 after being accused of decapitating a 15-year-old white girl. While there aren’t any grave markers for these victims, their deaths have continued to echo through America’s development as a 21st-century country. TCLF noted that, according to Dr. Jacova Williams of Clemson University’s Department of Economics, southern counties that held more historical lynchings have lower voter registration rates among African Americans today. This sad reality must be altered, and TCLF argues the only way to do it is by shining a light on such sites and their jarring stories. It’s key to our country's ability to heal and move forward as a collective society, they say. “Our shared and fragile landscape legacy has a powerful role to play in helping us understand where we come from,” said Charles A. Birnbaum, TCLF President and CEO, in a statement, “especially in the current debates, conversations, and analyses of our national identity.” These Shelby County sites are listed among 10 other at-risk historic sites and landscapes associated with human and civil rights in the U.S. Laid out in TCLF's Landslide 2018 report, every site is currently in danger of being redeveloped or demolished altogether. Some simply suffer from a lack of resources, an equally foreboding issue that plagues communities and organizations trying to bring recognition to near-forgotten places around the country. Other sites, like those found in Tennessee, have long been suppressed. But things are changing. This summer, The National Memorial for Peace and Justice opened in Montgomery, Alabama, and was dedicated to the more than 4,440 African American men, women, and children who were hanged in the South. The memorial, built by the Equal Justice Initiative and designed by MASS Design Group, has been praised by visitors and design critics alike for its beauty, timeliness, and national importance. Architect and speaker John Cary, who authored the 2017 book Design for Good, has toured public projects around the world. He described the National Memorial as “one of the most extraordinary memorial buildings" he's ever seen anywhere. Others agree and are calling it the most significant memorial on U.S. soil since Maya Lin’s Vietnam War Memorial in Washington, D.C. While a massive work honoring those lynched in the South is an incredible step forward, it’s still important to preserve the other places where the lynchings actually happened. TCLF placed these sites in its Landslide 2018 program to call attention to their fading history and to urge Americans and preservation groups to help keep them intact. The other at-risk sites include: Blair Mountain Battlefield in Logan County, West Virginia, the site of a four-day uprising by over 10,000 armed coal miners fighting for basic workers’ rights; Druid Heights in Marin County, California, a bohemian enclave north of San Francisco where poet and lesbian feminist Elsa Gidlow lived among a group of LGBTQ activists; The Hall of Fame for Great Americans at Bronx Community College, a monument featuring 96 busts that honor high-achieving individuals across various fields; Hog Hammock on Georgia’s Sapelo Island, home to the last descendants of the enslaved Saltwater Geechee community; Japanese American Confinement Sites located across the West Coast where over 120,000 people were held during World War II; Lincoln Memorial Park in Miami, Florida, a 20-acre African American cemetery in Dade County housing soldiers from the Civil War to the Iraq War; Lions Municipal Golf Course in Austin, Texas, the first desegregated course in the South; Princeville, North Carolina, the first U.S. town incorporated by African Americans; and Susan B. Anthony’s Childhood Home in Battenville, New York. All of these landscapes have played a critical role in America’s growth and continue to shape how we interact with one another, as well as how we fight and vote for a less violent, more equitable future.

To have provided effective compartmentation would have meant deconstructing the interior of the Mackintosh Building to find where voids existed. Only by stripping it back to its masonry structure could we have been certain of stopping all these voids and providing compartmentation […] comprehensive elimination would have meant stripping the building completely – thus destroying what we were aiming to protect and conserve.The GSA also used the report to advocate for their continued stewardship of the Mac and that they were in the best position to lead the next restoration, arguing that they were a working, hands-on school. The 2018 fire gutted nearly everything replaced in the $48 million renovation, and it’s unclear how much reconstructing the Mac will cost this time. However, whoever owns the Mac won’t be starting from scratch, as Page\Park’s extensive survey of the building created a comprehensive 3-D model of the entire library, including the original materials and techniques used by Mackintosh in 1898 and 1909. The next reconstruction is expected to take anywhere from four to seven years to complete.
