In the late 20th century, restricted by an a small landmass and extreme terrain, the Hong Kong urban area grew to become one of the densest and most vertical places on the planet, with more buildings taller than 500 feet than any other city in the world. But instead of the steel or aluminum structures used as scaffolding in Europe and the Western Hemisphere, the majority of skyscrapers built in Hong Kong and much of Asia used scaffolding systems constructed out of bamboo.
To create the structures, the high strength, lightweight material is strapped together with plastic ties by construction crews, who also use the structure as a ladder for scaling the building. Despite using few safety restraints, crews are able to construct up to 1,000 square feet of bamboo scaffolding in just one day. To protect the structure, nylon gauze is sometimes draped along the outside.
