I agree with vital role of Building cost and feasibility. But Nepal got total almost 25$ billions US dollars from various countries China, Japan, Korea, Finland, Germany, UK, USA, Russia, France, Brunei, Singapore and United Nation Organization. Where that money goes? It is just disappear in Government Officials pockets and Engineers pockets. Why do not we truly pour that money for country infrastructure development? In another point, Spending money in hard way or expensive way would be the better than making money disappearing into crooks pockets. At the end, we will have at least Road, Railway, Bridge, tunnel, water dam etc. What do you think?
