The scaffolding seen below is another good example of triangulation - or is it? The building under construction is a six story hotel in Marrakesh, Morocco (August 2006). However, if you look closely you will see that the scaffolding is not constructed from steel tube but entirely from wood.

 There are certain advantages to using this material;

It is light,
It is easy to transport,
it can be cut and shaped easily on site,
it is readily available,
it can be recycled,
it is cheap,
it can be erected quite easily to form a structure and dismantled with the same ease.

However, there is one very important disadvantage - it is not as safe as steel scaffolding and probably would not pass Health and Safety Inspections in most countries throughout the world. Look at the ‘planks’ the workers have to walk on - they look extremely insecure and dangerous.’
