I was employed on the construction of Taiwan High Speed Rail, in the 16km section I was on there 11 tunnels, earthworks and every type of bridge construction including cast in-situ and precast unit balanced cantilever, cast in-situ post tensioned viaducts. Steel section on temporary falsework. An interesting 4 years work
The Chinese builders cannot stop laughing at this "fastest bridge construction", as this is a 50 years obsolete approach. When a country is run by corporations, the only thing that is modern and fast is the way public money ends up in their pockets. But, this is obviously not one of those money-making things.
In Vietnam, it takes 3 years to assemble a medium bridge, a large bridge is expected to take 5 years, after construction, the road and bridge seem to curse each other because it is true that the road on the bridge and the ground road are different when assembled... the car runs Up and down the bridge, they were thrown.. that's the level of excellence....boring.
In my view these type of videos provides zero knowledge, it is just like a film scene.
Plz in these type of video provide the country name in which it is done and the duration in which this project is completed.
