• DHS unveils critical infrastructure Web site

    Designed to provide stakeholders and the public with easily accessible information about their role in safeguarding critical infrastructure and key resources (CIKR); the new CIKR Resource Center will offer information on Web-based seminars on the tools, trends, issues, and best practices for infrastructure protection and resilience; resources concerning potential vulnerabilities for chemical facilities; and guidance for all response partners on how best to prepare for and provide a unified response to disasters and emergencies

  • Oregon's bridges to be readied for the Big One

    There are 2,671 bridges in Oregon’s highway system; researchers develop a computer model which, for the first time, gives state authorities bridge-by-bridge estimates of damage, repair cost, and traffic delay costs associated with a shattering western Oregon quake; the new tool would allow engineers to prioritize which of the state’s bridges should get seismic upgrades

  • Worries about safety of California bridges with eyebar design

    Every so often the Bay Bridge closes because of widening eyebar crack; when the bridge opened seventy years ago, the design was considered safe, but structural engineers now say the eyebar design is an inherently unsafe; trouble is, dozens and dozens of California aging bridges use the flawed design

  • A landmark investment to finance Canada-U.S. grid connection

    The biggest Canada-U.S. power grid project — a privately funded 1,200- to 1400-megawatt transmission line between Quebec and southern New Hampshire — will lower the cost of power throughout New England; the project could also meet one third of the New England’s Regional Greenhouse Gas Initiative commitments with the hydroelectric power Hydro-Québec could pump through the line

  • Bay Area cities lag in making housing quake-safe

    Many public buildings in Bay Area cities have been retrofitted to make them more earthquake-resistant; most of the two types of private homes which are especially vulnerable to damage by tremors — wood-frame, “soft-story” buildings and concrete-frame structures that lack sufficient steel reinforcement — have not yet been retrofitted

  • Researchers look for a better way to build bridges

    Canadian researchers look for ways to make bridges sturdier; one project looks at the use of advanced fiber-reinforced polymers (FRPs) to protect critical concrete infrastructure against extreme shocks; the second study involves the use of ultra high-performance concrete (UHPC) to build long-life, lightweight and cost-effective bridges

  • New Army Corps of Engineers' policy instructs project designers to take rising sea levels into account

    The Army Corps will from now on incorporate estimates of rising sea levels in all its plans for flood control, navigation, and other water projects; the corps has had a planning policy for rising sea levels since 1986, but the instructions were less than a page long, buried in a 1,000-page document and largely ignored; the new policy is articulated in a 44-page stand-alone document

  • Search for answers in extensive Brazil blackout

    A huge power failure involving the world’s largest operating hydroelectric plant earlier this week cut off electricity to 18 of 26 states in Brazil, including the country’s two largest cities, São Paulo and Rio de Janeiro; tens of millions of people were affected; failure exposed the vulnerability of Brazil’s electricity infrastructure

  • Cyber threats now targeting traditional companies

    U.S. companies, even small and medium size, are more and more exposed to cyber threats from organized crime, foreign intelligence services, and probably terrorist organizations; 85 percent of U.S. critical infrastructure is owned and operated by private companies — and these companies are especially vulnerable to determined attacks which may ruin or seriously disrupt company operations

  • E.coli helps mend cracked pipes

    Aberdeen University students show how specific strains of E. coli, which are not deadly or poisonous to humans, could be used automatically to mend cracks that occur in household water pipes, cooling pipes in laboratory experiments, or water pipes in power plants

  • New York, Vermont governors: Champlain Bridge beyond saving

    The state of New York saved $10,000 by not performing an ultrasound signals test on the 80-year old Champlain Bridge, which connects New York and Vermont; without the test, the New York Department of Transportation was unaware of how pervasive the rot in the bridge’s piers has become; experts concluded last week that the bridge cannot be saved, and will have to be demolished and replaced; the cost of a new bridge is estimated at $50 million; the economic damage to the communities involved is incalculable

  • Detecting a silent bridge-killer

    New York State failed to make ultrasonic test of concrete piers, which could have avoided Champlain Bridge closure; a $10,000 high-tech ultrasonic test of the piers could have provided an early warning of lurking rot and given time to make repairs to stabilize the piers before the bridge became unsafe

  • Calls Come for 'Programmatic' P3 Approach

    Stakeholders in the market push for programmatic, rather than project-by-project, approach to financing infrastructure through public-private partnerships; “The cycle of infrastructure investment is ongoing since aging toll roads, hospitals, airports, and energy facilities need to be maintained and eventually replaced,” said Jennifer Tennant, assistant vice president for Moody’s

  • U.K. agency to increase flood protection

    The number of properties in England and Wales at significant risk of flooding could increase from 570,000 in 2009 to over 900,000 by 2035 at current levels of flood-defense investment; the Environment Agency says it is planning for the long haul, saying it is already planning to manage a predicted 1 meter rise in sea levels, and a predicted 10 percent increase in wave heights and wind speeds, both of which will increase the threat from coastal surges

  • House tightens chemical plant safety bill

    A House bill is set to tighten some provisions of the original chemical plant safety bill of two years ago; specifically, the House bill demands that chemical plants be obligated to replace the most toxic and volatile — and, hence, the most dangerous — chemicals they use in their operations with safer substitutes — but in a nod to the chemical industry, the bill focuses only on the highest-risk plants, and it would make them use safer chemicals or processes only when DHS determines that they are feasible and cost-effective
