  • Engineers create plan to replace damaged crane in NYC
    A team of engineers plans to replace a damaged crane on top of the One57 building in New York City after it came loose due to strong winds from superstorm Sandy. "We have no idea why, but it appears that it did not weathervane like it was supposed to," said Lawrence Shapiro, a crane engineer. "[E]ngineers are leaning toward surrounding the crane's superstructure with netting and scaffolding extending from the face of the tower," reports ENR. "Crews would then use the platforms to access the boom and take it apart, piece by piece, from the bottom up." Engineering News-Record (11/6) LinkedInFacebookTwitterEmail this Story
  • Fixing N.J.'s aging infrastructure a huge challenge
    New Jersey's aging infrastructure was ill-prepared for Hurricane Sandy, and it remains vulnerable any time there is widespread flooding, this article notes. A 2009 ASCE report said the state needed to spend about $9 billion to upgrade wastewater treatment plants and $7 billion over the next 20 years to upgrade drinking water infrastructure. "The numbers are so big it is going to rely on federal dollars and borrowing," said Rich Keevey, a state budget crisis task force member and former state budget director.

It kept the volume from completely draining out." The Kansas City Star (Mo.) (11/5) LinkedInFacebookTwitterEmail this Story

  • Understanding chemical kinetics could make concrete more sustainable
    Hydration processes affect the curing time and durability of concrete, notes Maria Juenger, associate professor at the University of Texas at Austin. If we understand the chemical kinetics that happens during those processes, we can "look at the life cycle performance of our concrete," and "[w]ith that understanding we can optimize the durability, optimize the cost and minimize the environmental impact," Juenger says.

  • BIM, precast used for $475M health care project in Canada
    The use of building information modeling technology for a $475 million health care building in Ontario is providing seamless coordination for design and construction services. The design team addressed challenges in coordinating several project components, including the integration of precast concrete panels. "Problems always get solved, but the goal of this process is to end up solving problems sooner at less cost," said Thomas Strong, virtual construction director at primary contractor EllisDon.

  • Geothermal systems as alternative energy source
    Some building owners affected by Hurricane Sandy were urged to shift to geothermal systems that use energy from the ground to heat and cool buildings. However, "the biggest obstacle currently to geothermal energy is the initial cost, which can be more significant than a traditional furnace replacement," said Daniel Goodwin of the Miller Environmental Group. "But from a new construction standpoint, when you look at the numbers and the tax credits and things out there, it really becomes a no-brainer."

  • U.S. lawmakers turn to threat of "fiscal cliff"
    With the question of who will be president answered, the U.S. must now confront the "fiscal cliff" of tax hikes and spending cuts that economists say could return the economy to decline. Speaker of the House John Boehner, R-Ohio, gave a speech on Capitol Hill that struck a conciliatory tone but seemed to flatly reject any compromise that included an increase in taxes.
