Billions of dollars are spent by cities and countries to prepare for summer and winter Olympics. Many stadiums, housing and other infrastructure are built to not only be able to handle the games, but also the enormous amount of people that will eventually inhabit the city for a few weeks. But, that’s just it, it’s only for a few weeks. What happens after the games are over and there’s no longer a need for an International Broadcast Center or a handball venue? In the past, the answer has been to let the area rot away and be a hotbed of vandalism, but Rio has taken a different approach.
The City of Rio de Janeiro and Brazil took a lot of heat for unfinished facilities, polluted waterways, down to the wire infrastructure finish dates, as well as a high number of construction worker fatalities during preparation before the games began. However, city officials and designers made an extremely smart decision when they decided to design the facilities using a concept called “nomadic architecture.”
Nomadic architecture allows the parts and pieces of the Olympic buildings to be easily dismantled and reused on other projects, effectively recycling the buildings. Several buildings used for the 2012 London Olympics also used this nomadic concept, but Rio has taken it to the next level. AECOM, who designed the Olympic structures in Rio, also created the master plan for London. The Future Arena and the Olympics Aquatic Center are the only true “nomadic” structures, out of the 30 total buildings, says Wired, but the others will be dismantled and the parts repurposed.
The city already knows exactly how the disassembled parts will be used in the future, too. The Olympic Aquatic Stadium will transform into two smaller pools in a different area of the city. Many of the building components from the Future arena will be used to build four schools. The broadcast center will be repurposed into a high school dormitory for gifted athletes.
It’s a positive sign that Olympic officials and host cities are beginning to understand the importance of sustainable and reusable structures. It hasn’t always been this way, even within the past decade. Beijing’s National Park, which housed the 2008 games, still stands as a tourist attraction and costs roughly $11 million a year to maintain, according to NPR. The Olympic Park in Athens, 2004’s host, lies abandoned and in a state of ruin (pictures here via The Guardian). The Bosnian Conflict in the early 90’s saw the 1984 Winter Olympics site used as an artillery launch position, according to WSMV in Nashville.

Asphalt is one of the world’s most popular pavement materials. Because of that, researchers and scientists are constantly looking for ways to improve upon it. Additives have been included in some asphalt mixes for years to improve strength, but recently researchers have been getting pretty clever with the types of additives they’re testing.
As great as a product as asphalt is, there’s no doubt that there is room for improvement. Scientists all over the world are trying to solve its most common issues, such as potholes, cracking, ice build-up, and storm water drainage. Los Angeles is now tackling another issue with the material: heat island effect.
In March of this year, Elon Musk announced that Tesla would begin taking orders on their Solar Roof Shingle concept. Tesla Solar Roof is a solar power roof system that eliminates the need for bulky solar panels installed over top of traditional roof materials. Instead, the shingles themselves, which come in a variety of different styles, are the solar panels.
At the company’s second quarter earnings report, Tesla announced that the first solar roof installations have been completed.
Standard vertical elevators have had it too good, for too long. After the first cable dependent elevator was unveiled in 1857, not much has changed in the elevator industry. They’re still using cable systems and still only going up and down. But not anymore. ThyssenKrupp has officially made a multi-directional elevator a reality.
There’s no shortage of company’s trying to improve the world’s roadways. Asphalt and concrete each have their own disadvantages, especially when maintenance environmental factors are taken into consideration. Plastic is a major problem for landfills, as well, as it can take an estimated 500 years to fully decompose. One UK company believes they can solve both maintenance and environmental problems through the use of recycled plastic.
The Massachusetts Institute of Technology (MIT) is constantly researching ways to improve construction process and materials, like this material 10 times the strength of steel, or this solar cell that’s lighter than a soap bubble, or this “reversible concrete.” This time the Institute is showing off its autonomous robot that can spit out building structures on site within hours.
One of the most challenging issues with modular construction, of any kind, is the sheer size and weight of many of the components that need to be transported and lifted in place once onsite. That presents a specifically tough situation for jobsites that are not easy to get to. Arup, a design, engineering, and consulting team in the United Kingdom, has developed and successfully implemented what they say is the “world’s first modular glass-fiber, reinforced polymer bridge.” You may remember Arup from their testing of a “living wall” scaffolding cover that we wrote about last year.
Snow causes all kinds of travel nightmares and not just on the roads. Snow and ice can cause major airline delays and flight cancellations. Because of these issues (and the large amounts of money to be gained by solving them) several different groups of researchers have been hard at work figuring out ways to reduce and remove snow and ice from pavement without the need for chemicals and snow plows. The first technology to get a full scale test slab installed at an American airport, however, came from Iowa State University professor Halil Ceylan.
Maybe I’ve had my head in the sand for a while (forgive the pun right out of the gate), but I've recently found out that the world is suffering from a shortage of sand. The New York Times reports that the increasing demand of sand from manufacturing and construction in combination with rising sea levels and human development of shores is reaching crisis levels. Sand is used in plenty of construction activities, from mortar to concrete to brick and asphalt. We use a LOT of it. In fact, concrete production takes a whopping 80 percent of all the sand that is mined. So what can we do? One company says the answer is to drink more beer.
Solar roofs are an obviously popular choice for those interested in conserving energy, but traditional panels are extremely clunky and expensive. Tesla and CEO Elon Musk announced last year that they have solved that issue, which the impending release of Tesla Solar Roof, which look like a traditional roof shingle.
