Doing business in Laos especially in construction and road are major and big project, but here is what normally happens:....
1st contractor some upper level official
2nd contractor some relatives from the upper level official
3rd contractor some friends (upper class) from the relatives
4th contractor some friends from the upper class friends
5th contractor this some friends do it themselves for pass it to 6th contractor
6th contractor (final stage) some cheap and fast labour from neighborhood
So try to squeeze in between 3rd or 4th and this is big business. Cheers
