  • Shotcrete helps make big dome resistant to tornadoes
    An inflatable fabric dome -- with a bit of construction technology -- can hold up to 800 people and should be resistant to an EF-5 tornado. It's being constructed at Smithville School in Mississippi. Once the fabric is inflated, insulation is added to the inside and then a rebar grid is tied to the inside of that. "It will look like a big bird cage for a little while, and then we spray concrete -- which is called shotcrete -- on the inside," said Randy South, president of South Industries, the company building the structure. "We embed that rebar and when the rebar is all embedded, we let the concrete cure for a little while, turn the fans off and you got a concrete building." WTVA-TV (Tupelo, Miss.)

  • Pervious concrete can be helpful to horses, barns
    The use of permeable concrete can diminish the risk of injury to horses and prevent runoff in barns and stables, according to Stephen Higgins, of the University of Kentucky’s College of Agriculture. "Because of its filtering ability, pervious concrete doesn’t allow a meandering stream of soap suds, urine, and other wastes from flowing offsite," Higgins said. This means there is less chance of injury due to slipping. "The material also ... allows [the liquids] to drain slowly, allowing infiltration by the soil and utilization by plants."

  • Technology helps AEC firms document "green" building
    As the interest in sustainable building grows, so too does the need for help to manage the documentation that invariably accompanies a project. For instance, SCS Global Services and GreenWizard are partnering on a solution to provide companies with a better way to locate and procure certified materials for LEED projects. Others are working together to "provide environmental and sustainability certification, auditing, testing, and standards development."

  Leadership & HR  
  • Is your very existence a threat to your employees?
    By simply existing, bosses psychologically threaten their workers in fundamental ways, says David Rock, director of the NeuroLeadership Institute. Leaders have higher social status and greater autonomy than their employees, and that imbalance, left unchecked, can demoralize and demotivate workers. "A smart boss will notice this and do all sorts of things to try to fix it," Rock says. The New York Times (tiered subscription model) (3/23) LinkedInFacebookTwitterEmail this Story
