BAMBOO Scaffolding!?

In this episode we unveil the bamboo scaffolding that is synonymous with Hong Kong.

-Most nations these days use metal scaffolding which are loaded into trucks in stacks. The problems with metal scaffolding is that it’s heavy, bulky and takes a lot of space. In China, India and primarily Hong Kong bamboo scaffolding is the only type of scaffolding they use. As you can see here, a couple hundred bamboo poles can fit on the back of a single truck. When constructed this will provide a much greater amount of scaffolding per truckload then steel scaffolding.

-Bamboo scaffolding is highly popular in asia as it is a renewable resource that grows quickly and is readily available locally.
-Bamboo scaffolding is built by tying bamboo poles together with nylon straps
-The poles, beams and cross braces can be used for up to 7 years at which point they’ll be used as walkboards which are the horizontal beams workers stand on. After they are deemed not safe as walkboards they’ll be used as firewood on site

-Steel scaffolding has locks and pins which secures the connection where bamboo does not
-A bamboo connection is simply tied with nylon which isn’t as secure
-the walkboards on steel scaffolding is all securely fastened where the bamboo ones just lay on top unfastened.
-with bamboo poles it’s not possible to tell how old they are and when they need to be replaced. -This problem could be alleviated by date stamping the poles but I’m guessing these guys who build these bamboo scaffoldings are so experienced with how the poles feel, they can probably tell when it’s time to recycle a pole.
-there are a few major differences between the 2 types of scaffolding, first bamboo poles weigh ½ as much as the steel ones and second steel scaffolding can take days or weeks to construct where bamboo scaffolding can’t be built within a day or a few days depending on the size of the building.
-different sources online have stated that bamboo scaffolding has withstood strong winds and just flexed in place where metal scaffold was fallen apart damaging the structure it was built around.

-When it comes to very tall buildings bamboo scaffolding higher than 15 meters or 45 feet needs to be designed by a design engineer who specializes in bamboo scaffolding.
-While it might seem unbelievable, towers in hong kong that are 70 stories tall get wrapped with bamboo scaffolding.
-The only major downside to bamboo scaffolding, and the rest you don’t see it being used in other parts of the world like north america is that is looks very precarious and dangerous.
-as of 2013 there are 1751 registered bamboo scaffolders and around 200 bamboo scaffolding companies in Hong Kong
-data collected over 5 years shows that a total of 16 people died by falling from the scaffolding, 9 of those 16 being scaffold builders.
-The bamboo scaffolder is becoming a dying profession in Hong Kong for obvious reasons but the situation is further worsened by the fact that wild bamboo groves are being clearcut for expanding Chinese cities which will raise the price of bamboo that is needed for this business.
