Baan Mankong is like this photo: you see the elements but can not really make a very cohesive structure out of it ( or say what is actually being constructed). Reading about BM was one thing, seeing in reality- something different ( not necessarily worse!). I am sure this construction has some sense- the piles are serving a certain purpose.
It’s similar with BM- the goals are a great structure. Are they being fulfilled and in what way- its a different story. The overall evaluation of the de-codi-fying trip can be seen in report of BUDD group D. Some personal impression in a slightly humorous way- over here
