Back in 2003, the District of Columbia Water and Sewer Authority proposed building three tunnels to help manage sewer overflows. It now proposes suspending construction of the tunnels in favor of doing an eight-year study on green infrastructure to see if there are more sustainable options to deal with the problem. "At the end of that analysis, we will make a recommendation to the Environmental Protection Agency to do [an] all-green, all-tunnel or some hybrid program," said Pamela Mooring, the authority's external communications manager.
Three-dimensional city modeling could show and animate urban features such as road networks and building heights, which could aid in organizing placement of structures and be a tool to help future decision-making, this article notes. Three-dimensional "simulations of cities have the potential to help engineers and planners anticipate natural disasters and population growth, and to better plan for them in a way that goes far beyond rendering cityscapes as if they were in a video game," Emily Badger writes.
In addition to the $5 trillion a year the world needs to spend on infrastructure development, it could need an additional $700 billion annually to help limit temperature increases, according to a report for the World Economic Forum by Accenture. The World Bank forecasts a temperature increase of 7.2 degrees Fahrenheit over this century. The WEF says spending is necessary to beef up "renewable power, low-carbon transport and energy efficiency."
The top engineer at the $12 billion Hanford nuclear waste treatment plant in Washington suggested in December that "all activities affecting engineering design, nuclear safety, and construction and installation of all structures, systems and components be stopped" because of quality concerns. He has since left his position. However, the Department of Energy says the project's "technical uncertainties" have been dealt with, the project will continue and the department "as appropriate, will ramp up construction work not impacted by the remaining technical issues."
Part of a building under construction collapsed in Jakarta, Indonesia, today, killing three workers and injuring 14 more. Government officials said no permit was issued for the construction project, and added that they planned to tear down the remainder of the building.
