• Shift of Earth's magnetic north pole affects Tampa airport

    Magnetic changes in the core of the planet shift the Earth’s magnetic pole at nearly 40 miles a year toward Russia; as a result, Tampa, Florida, International Airport has closed its primary runway so it could be redesignated 19R/1L on aviation charts; it has been 18R/36L, indicating its alignment along the 180-degree approach from the north and the 360-degree approach from the south; the FAA required the runway designation change to account for the shift in the Earth’s magnetic pole

  • Recycled Haitian concrete safe, strong, cheap

    Nearly a year after the 7.0 magnitude earthquake, most of the damaged areas of Haiti are still in ruins; researchers find that concrete and other debris in Port-au-Prince could be safely and inexpensively recycled into strong new construction material which meets or exceeds the minimum strength standards used in the United States

  • China Looks to Invest in California's High Speed Rail

    China looks to add California’s extensive high-speed rail project to its resume; with experience in rail projects both at home and throughout Asia, China can also bring financing to the table as well as project expertise

  • Groundbreaking for $1.2 billion NSA Utah center

    Today is groundbreaking day for the Utah Data Center, a $1.2 billion project which will employ more than 10,000 people for its construction, and is thus seen as the salvation for the state’s beleaguered construction industry; the National Security Agency (NSA) will use the climate-controlled environment of its computerized core as a repository for information gathered by different branches of the country’s intelligence apparatus, hence the facility’s nickname, “The Spy Center.”

  • China, U.K. pursue major rail projects; U.S. does not

    Unlike almost every other developed nation, the United States has no national transportation strategy; the nation fails to raise taxes that are supposed to pay for roads and rails. Gasoline taxes, for example, cover only about 50 percent of road projects, much lower than in the past, according to recent Federal Highway Administration figures; once the U.S. recognizes that it needs diversified and integrated air, rail and road transportation, it could well end up importing the technologies, products and expertise it has failed to develop

  • Giving crowds a lift with spiral escalator

    A monorail-inspired design could help create the world’s first continuous spiral escalator; the spiral escalator could transport larger numbers of people than a lift in a vertical space too narrow for a traditional escalator; this could reduce the floor space needed in buildings for personal transporters and cut the cost of putting escalators into underground railway stations

  • Quake experiments may lead to sturdier buildings

    Johns Hopkins researchers will study how seismic forces affect mid-rise cold-formed steel buildings, up to nine stories high; the cold-formed steel pieces that are commonly used to frame low- and mid-rise buildings are made by bending about 1-millimeter-thick sheet metal, without heat, into structural shapes; these components are typically lighter and less expensive than traditional building systems and possess other advantages

  • Flood control projects in Las Vegas

    Las Vegas is the middle of the desert, and as other desert cities it falls victims to flash flooding during the rainy season; the city has launched a $30 million project to protect local roads and businesses from floods

  • Thirteen Georgia dams could be reclassified as high risk

    The number of dams designated high risk under Georgia’s Safe Dams Act could more than double in two counties in the state, but a backlog in state enforcement because of budget cuts could drag the reclassification process out years longer than scheduled

  • Minneapolis bridge collapse spawning new bridge research

    Oregon State University developed a new system to analyze the connections that hold major bridge members together; the work also brings focus to a little-understood aspect of bridge safety — that most failures are caused by connections, not the girders and beams they connect, as many people had assumed. The issues involved are a concern with thousands of bridges worth trillions of dollars in many nations

  • Bacteria knit together cracked concrete

    Students at Newcastle University genetically modified a microbe, programming it to swim down fine cracks in the concrete; once at the bottom, it produces a mixture of calcium carbonate and a bacterial glue which combine with the filamentous bacterial cells to “knit” the building back together

  • Purdue engineers test effects of fire on steel structures

    Building fires may reach temperatures of 1,000 degrees Celsius, or more than 1,800 degrees Fahrenheit; at that temperature, exposed steel would take about twenty-five minutes to lose about 60 percent of its strength and stiffness; Purdue researchers experiment with ways to make steel more fire-resistant

  • GWU earthquake simulator helps engineering prepare for the real thing

    George Washington University laboratory’s “shake table” — a $1 million, 10-by-10-foot metal structure that moves in six directions — replicates earthquakes and allows engineering students to test construction materials to see how they hold up under tremors of varying strength

  • New Orleans levee committee uneasy with Corps of Engineers modeling

    The Army Corps of Engineers uses complex computer models for hazard analysis calculations on which billions of dollars worth of repairs and improvements to the federal hurricane levee system are being based; the members of the regional levee commission want their own expert to scrutinize these computer models

  • U.K.'s government unveils £200 billion National Infrastructure Plan

    David Cameron announces infrastructure plan to rebuild the economy a week after sweeping government cuts; the plan calls for a government commitment of over £40 billion directed to infrastructure projects, including a Green Investment Bank that provides up to £1 billion toward a commercial scale carbon capture and storage demonstration projects; £30 billion for transportation, including a high speed rail network, maintenance, and investment in local roads and rail and funding towards the Network Rail
