Shatin to Central Link (SCL) is a major infrastructure investment currently under construction in Hong Kong and aims in connecting a number of existing railway lines passing through different districts of the island. The line passes through already developed urban areas, encountering different topography and geology conditions, which require not only the application of different construction methods, but the use of different types of the same equipment as explained by two of the leading companies in the tunneling construction industry, having undertaken the construction of specific tunnel sections.
Measurand's ShapeAccelArray instrumentation system is used in the case of the structural monitoring of the Mactaquac Dam Generating Station, located in Keswick Ridge, New Brunswick, Canada. Alkali-aggregate reaction (AAR) has led to concrete expansion and the observation of substantial deformation at the Dam.
An earthquake-detection system developed by the University of California Berkeley’s Seismological Laboratory performed well during the recent earthquake that struck the Napa Valley region on August 24. The system was able to produce a warning message 10 seconds before the magnitude-6 temblor struck. "It was definitely a great proof-positive that the system works just like we'd hoped," says Jennifer Strauss, the lab's external relations officer. "One of the things the Napa quake did show us is you need to make sure there are enough sensors," says Strauss. One member of the lab even stated the warning could have gone out 2.5 seconds earlier had the lab received more funding to install more sensors in the area. California unanimously passed a bill last year that would create a state-wide early detection system. Funding for such project, however, has yet to be found.
Monsoon season, which is currently hitting India, Pakistan and other Asian countries, causes extensive floods and triggers landslides, with detrimental effects for the citizens of the affected countries. A new mathematical model, currently under development, aims in assessing the extent of anticipated damage and improving the civil protection and warning system.
Last year's massive flooding in Colorado's Front Range affected a widespread area, destroyed roads and bridges, blocking access to residential areas for extended periods of time, and washed away homes. Based on a study conducted by the University of Colorado Boulder, the tweets sent during the flooding events played an important role in the preliminary reconnaissance of the infrastructure damage and helped geotechnical and structural engineers to more efficiently spend their time and efforts during their visit to the affected areas.
This past summer, a step forward was taken for the realization of the Trans-Afghan natural gas pipeline project, also known as TAPI. TAPI is an ambitious $7.5 billion project, that aims in trasferring natural gas from Turkmenistan through Afghanistan to Pakistan and India. Even though it has to overcome many obstacles due to the unstable political and economic conditions in the involved countries, TAPI can have major geopolitical effects in the area.
Skanska stopped work on the world’s tallest modular building last week over a dispute with the project’s developer Forest City Ratner. Skanska feels that the delays to the project have resulted from the modular designs for the buildings. They feel that Forest City Ratner should be held responsible for the cost overruns. Richard Kennedy, co-chief operating officer of Skanska USA, told the Wall Street Journal, “it [the design] just doesn’t work the way it was sold to work. It was represented to be a complete and buildable modular design,” he said. “That simply was not the case and that’s what we’ve been struggling with.” Forest City Ratner, however, stands by their design and believes the dispute is based on financial reasons.
