Chinese Construction in South China Sea Destroying Habitat

The South China Sea is about the size of India and is comprised of hundreds of islands and atolls, a geography that results in some of the highest marine biodiversity on the planet, with 571 known species of reef corals, for instance. China's massive race to seize the disputed area and hurriedly build it out with artificial islands and airstrips has resulted in tons of sand being dumped on sensitive and irreplaceable habitat. Satellite photos show the militarized build-out of the once-thriving Subi reef.  An airstrip on a reef. Is that a good idea?

Longest Freestanding Balanced Cantilever: Temporary and Hair-Raising

An enormous bridge in Scotland called the Queensferry Crossing now holds the temporary Guinness World's Record for Largest Freestanding Balanced Cantilever in the world. The cantilevered center span of the nearly completed bridge is about a half-mile long. It is supported at this time by the center tower alone. I trust the design, but let's run across it, shall we? 

Cincinnati Construction Sign Expresses Frustration

A construction sign in front of the Cincinnati music hall (which is currently being refurbished) seems bored with its mission of dispensing useful construction updates.  It's feared all the country's construction signs will begin to likewise self-express, causing confusion for passerby. We all have these moments, don't we?

Monaco To Reclaim 15 Acres from Sea for Wealthy New Neighborhood

The tiny principality of Monaco, prized for its compact and breathtaking natural beauty, is running out of building space.  What's a haven for the world's wealthiest citizens to do? Reclaim land from the sea, of course, at a cost of around $2B. May I sleep in one of the garages?

Civil Engineering Society Issues First Tsunami-Proof Building Standards

The new standards apply to steel-reinforced concrete buildings in "inundation zones." Wood structures need not apply. A major factor in the design standards takes into account the destructive power of swiftly moving shipping containers and other examples of large debris. We'll take a gander as we sprint to higher ground.
