Why Hong Kong uses bamboo scaffolding, and meet the spider-men who climb it (scmp.com)
Hong Kong is one of the last places in the world where bamboo is still widely used for scaffolding in construction. It’s flexible, strong and cheaper than steel and aluminium — metal alternatives that are now more commonly used in mainland China and elsewhere in Asia.

Innovative ways to float skyscraper-sized wind turbines (mena-forum.com)
Record-tall Wind Turbine Towers with 3D-printed Concrete Bases were in the news a few years back. Today, here are six innovative ways to float skyscraper-sized wind turbines. These enormous turbines can reach up to 240m tall—about the size of a skyscraper. Since they are so tall, strong winds far above the sea surface tend to cause the turbine to tilt, so platform designs focus on minimising this tilt while still being cost-competitive with other forms of energy.

The engineering behind the San Antonio River Walk (practical.engineering)
I am on location in downtown San Antonio, Texas, where crews have just finished setting up this massive 650-ton crane. The counterweights are on. The outriggers are down. And the jib, an extension for the crane's telescoping boom, is being rigged up. This is the famous San Antonio River Walk, a city park below street level that winds around the downtown district.

The Engineering of Wildlife Crossings (practical.engineering)
This is the Wallis Annenberg Wildlife Crossing under construction over the 101 just outside Los Angeles, California. When it’s finished in a few years, it will be the largest wildlife crossing (*of its kind*) on the planet. The bridge is 210 feet (64 meters) long and 174 feet (53 meters) wide, roughly the same breadth as the ten-lane superhighway it crosses. Needless to say, a crossing like this isn’t cheap.
