Hello Abhishek,
In Delhi, I think only IIT-Delhi offers M.Tech in construction management.
For the list of colleges in India that offer this course refer to the following link:

For every course the fee structure is same. Including hostel fee, it is 3 lakh rupees. Only tuition fee is 2.4 lakh rupees.

Hello Harsh,
These are the best two in India. Prospects are best here after passing out than anywhere in India. DRDO, ISRO, Armed Forces and some public or private companies also are recruiters.

M.Tech in biotechnology graduates have a lot of research opportunities besides teaching and jobs with manufacturing companies in operations and maintenance departments.

Hello Lalith,
Besides IITs and NITs, there some top universities for doing the master degrees.
You can opt for BITS, Pilani. It is a top university for all the degrees and is the best among the private universities in India:
The admission for M.Tech is based on an entrance test conducted by that institute.
For more details refer: www.bitsadmission.com.
Then you can go for VIT University and Manipal University. These are also better, if you don't get BITS, Pilani.
