I have doubts on how much we have learnt. I was speaking to the guy incharge of karnaphuli tunnel project last month, he said the chienese keep secrecy of their design and work and do not want to share the know how. Even they have their design details and paperwork in mandarin so our engineers cannot pickup. Same maybe true for the bridge I fear.
But definitely the engineers who worked must have learned heaps. One day we may help other countries build their mega projects, insallah.
Maybe she hasnt desided yet which name to put. Hers or her son's.
The general level of English proficiency in China remains low, even today. Almost all documentation (even engineering research) remains in Mandarin, as far as I know.
I don't think the Chinese were trying to hide their designs or technology.
The main bridge design was made by AECOM, in Dallas, TX anyway.
However MBEC folks completed the work efficiently and I'd say sooner than other countries (including India) could ever have.
Projects like Mongla-Khulna rail link and Rampal Maitry Powerplant are far simpler and smaller in scope but Indian contractors are highly inefficient and drag them on for ages, increasing both scope, ETA and budget by sometimes 300-500%.
