Man, Hong Kong's skyline is dominated by some of the world's tallest buildings. However, the city still uses bamboo scaffolding for much of its construction work – a traditional skill passed down over 5000 years.
As you know, bamboo is sustainable, lightweight and cheap and, as long as it remains fairly dry, a good construction material with significant mechanical properties. Researchers, engineers, environmentalists and bureaucrats have taken an increasing interest in the craft, such that regulations and practice continue to be improved and refined.
Hong Kong obviously does not have the safety and structural design codes that we do here in the US. However, the bamboo structures seem pretty sturdy and safe. Bamboo is a weed and it grows very quickly so there is tons of this recyclable resource everywhere here in China.....Brilliant!!
