Elon Musk, frustrated by LA’s heavy traffic, has proposed to create tunnels for an underground transportation system. And his newly established Boring Company, is exploring ways to cut down tunneling costs, in order to make his plan feasible. 

Last February, the futuristic Kennedy Town Swimming Pool (KTSP) -located in an historic Hong Kong neighborhood- was completed. The new civil and recreation hub, built beside Victoria Harbour, now serves as an icon for the community, and has helped rejuvenate a neglected district of otherwise vibrant Kennedy Town. Designed by Farrells, KTSP has won a 2017 American Architecture Prize in the Recreational Architecture category.

The King Abdullah Petroleum Studies and Research Centre (KAPSARC), rising out of the desert landscape of Riyadh, is a non-profit institution for independent research into policies that contribute to the most effective use of energy to provide social wellbeing across the globe. Designed by Zaha Hadid Architects, the futuristic building opened its doors last October for Saudi Design Week 2017. 

A team of researchers from the Department of Energy’s (DOE’s) Lawrence Berkeley (Berkeley Lab)  and Lawrence Livermore (LLNL) national laboratories, as well as from the University of California at Davis, have developed the first-ever end-to-end simulation code to precisely capture the geology and physics of regional earthquakes, and how the shaking impacts buildings. The code will take advantage of exascale supercomputers, the future supercomputers that will be 50 times faster than the US’s most powerful system today. Their work is part of the DOE’s Exascale Computing Project (ECP), a collaborative effort between the DOE’s Office of Science and National Nuclear Security Agency and was recently published in the Institute of Electrical and Electronics Engineers (IEEE) Computer Society’s Computers in Science and Engineering. 

On Monday, November 20th, the Georgia Dome – an 80,000-capacity stadium that opened in 1992 and hosted events in the 1996 Atlanta Olympics, was torn down. More than 2,000kg of explosives were used for the implosion, which took place at 7:30 a.m. , and was covered by the local media. The stadium, which was also the Falcons’ home for the past 25 years, was one of the country’s largest domed stadiums and its construction had cost $214m. It is now replaced by the adjacent, newly erected $1.6 billion Mercedes-Benz Stadium, which opened in August this year.

The Jacques Cartier Bridge, dating back to 1930,   is a steel truss cantilever structure over the St Lawrence River in Montreal, Quebec. Its illumination was the centerpiece of the city’s 375th and Canada’s 150th anniversaries, with 2,800 light fixtures that will light up the lively Old Port every night for the next ten years.  

Construction work in China is taking place at a frenzied pace the last few years, but since all that new infrastructure requires space, in many occasions buildings have to be torn down and residents to move in order to make room for new projects. There are however, dwellings that stand alone like a nail that refuses to be hammered down, the so-called ‘nail houses’, when owners resist dispossession of their land by developers or hold out for better compensations.

New York City, like other older urban communities, is largely serviced by a combined sewer system where storm water and wastewater are carried through a single sewer line to the city’s 14 treatment plants. These facilities can manage and treat all the wastewater produced in the city on a dry weather day (1.3 billion gallons on average) and also have the capacity to clean more than twice the dry weather flows on a rainy day. But during intense precipitation events, the storm water exceeds this capacity and overflows can be discharged into local waterways. In an effort to improve water quality, the city’s Department of Environmental Protection (DEP) is building rain gardens, designed to absorb polluted storm water that would otherwise end up into the sewer system.

It was April 4, 2017, when the work of tunneling machine Bertha was complete, breaking through into her disassembly pit and marking the end of the 1.75-mile long State Route 99 (SR 99) tunnel beneath Seattle. Now, the Washington State Department of Transportation released a drone video that shows the ongoing construction work from end-to-end inside the tunnel.
