The next generation of asphalt and concrete pavements used to build and rebuild roads, bridges and other paved surfaces in much of the world likely will be based on a design guide produced by researchers in ASU’s Ira A. Fulton School of Engineering.
Officials with the Transportation Research Board of the National Academy of Sciences, in addition to the American Association of State Highway and Transportation Officials (AASHTO), have approved new design guidelines for pavements developed by a team led by Matthew Witczak, a professor in the Department of Civil and Environmental Engineering.

When choosing a building envelope or façade , engineers and designers can work with or against the surrounding environment. The initial choices in designing the building envelope determine the degree to which mechanical systems and excess energy are required to facilitate human comfort, says Albert Bicol, a partner with Cobalt Engineering, a design company with offices in British Columbia and Toronto.
Bicol says half the world’s energy is expended on building lighting, heating, ventilating and air conditioning and 65 per cent of that energy is lost in transmission. A net zero approach to building design eliminates dependence on outside energy sources while optimizing comfort.

An improved, more environmentally friendly Engineered Cementitious Composite (ECC) is the star of the short course "Understanding and Using Bendable Concrete" set for June 24-26 at the University of Michigan in Ann Arbor, Michigan.
This new material bends but does not break because specially coated microscopic polymer fibers slide past each other instead of snapping under stress. Reducing the brittle nature of concrete opens a new world of possibilities for commercial construction and civil infrastructure by enhancing durability, safety, and sustainability.
The course will be taught by inventors Victor Li, E. Benjamin Wylie, Professor of Civil and Environmental Engineering at the University of Michigan, and Michael D. Lepech, Assistant Professor of Civil and Environmental Engineering at Stanford University. They will cover materials, applications, and economics of bendable concrete.

When engineers designed the 1,671-foot Taipei 101 skyscraper, they had to calculate stress factors such as load, the weight of materials and contents and how the building would twist under wind pressure - always mindful that Taiwan has frequent earthquakes .
All of that means erecting the world's tallest building is better understood than the stress factors in the 26 bones of a human spine. But a robot in a lab at the University of Tennessee Health Science Center is changing that, making spinal medicine more precise.

The Canadian Museum of Nature will undergo a dramatic change in appearance this summer with the construction of a $10-million glass tower above the front entrance, which, according to its designers, pushes the limits of glass and structural engineering.
Two storeys of structural glass will be suspended from a cantilevered roof and supported by a cluster of interior steel columns. "It's pretty acrobatic," says Toronto architect Bruce Kuwabara.

MUMBAI: The Brihan-Mumbai Municipal Corporation (BMC) has voiced concerns over Chinese firms putting in bids to construct the Rs 600-crore Vaitarana Dam in Maharashtra.
BMC is driven by security issues raised by the National Security Council (NSC) after several Chinese companies showed interest to participate in hydel power projects coming up along the national border and security sensitive areas.
Chinese construction giants such as Chinese Water & Hydro Engineering (CWE), China Gezhouba Group, Sino-hydro, Harbin Engineering, China International Water & Electric have bid for the construction work of the Vaitarana Dam.

In the UAE it often seems only the limits of the human imagination stand in the way of an architect’s dreams of ever-more grandiose buildings. But even here the designs of ever-higher and increasingly elaborate skyscrapers must survive the ultimate test – the realities of Mother Nature.
The Emirates’ unprecedented building boom has made the country the second largest market in the world for a little-known branch of science called wind engineering.
These experts take an architect’s drawings and sketches of a proposed building, from which they create a scale model that then undergoes the ravages of a wind-tunnel testing . This enables wind engineers to measure the stresses and strains a high-rise will undergo several hundred feet from ground level. ....click the link to read more

What mind-blowing innovation does Royal Caribbean plan for its next ship?
The Cruise World has been abuzz over the question for more than a year, and now it finally has an answer: A massive "Central Park" at the center of the vessel that boasts soaring trees, live grass and outdoor restaurants.
The new area, which Royal Caribbean plans to announce this afternoon at a press conference in New York, will be the central feature of the line's so-called Project Genesis ships launching in 2009 and 2010.
"This is very different from anything on any of our ships," the line's executive president, Harri Kulovaara, tells USA TODAY in an exclusive interview. "This is going to have real gardens, grass and trees. It has taken a lot of engineering."

Pneumatic pipe ramming continues to prove that it is one of the most versatile
and effective trenchless methods. With much of the attention being placed on pipe
ramming’s effectiveness for assisting directional drilling operations, it is easy to overlook
pipe ramming in its more traditional role of casing installation. BTrenchless
(a division of BT Construction), Henderson, CO, recently showed just how effective pipe
ramming can be for large diameter casing work. ....click the link to read more

It has been claimed that false and misleading information was used to justify some of Japans most spectacular road building projects.
Kuniichiro Takahashi, the former president of the state highways agency has claimed that the hugely indebted Government has rediscovered its addiction to public civil engineering works and has earmarked nearly 70 trillion yen (£311 billion) in its budget for road and rail building projects over the next decade.
Ridiculing these new “roads to nowhere”, Mr Takahashi said they were almost certainly unnecessary in a country whose population is ageing, shrinking and buying fewer cars every year. However, major road and rail construction continues to be the favourite tool of pork-barrel politics in Japan.
