Keep digging Government websites and you come across lots of interesting stuff. Wonder if we should build a search engine dedicated to sarkaari websites. Anyway, here is an interesting site: Committee on Infrastructure. This committee was setup:
... with the objectives of initiating policies that would ensure time-bound creation of world class infrastructure delivering services matching international standards, devel- oping structures that maximize the role of public-private partnerships (PPPs) and monitoring progress of key infrastructure projects.
Last updated note on the website says Sep 9 2008, so its fairly current! find consultation papers, guidelines for PPP (the catch word these days, isn't it!?). There is a "publications" section there, and hey, we have manuals of standards and specifications for two and four laning of highways!. Analyst type members here, worth a look.
