How to determine which period of CS Index should be used for

evaluation of tender?

Answer:

The CS Index for the month that the tender has closed should

be used.

A tender closed on 17th March 2011. Hence, March 2011 CS

Index will be used for evaluation.

A tender closed on 31st Dec 2011. Hence, Dec 2011 CS Index

will be used for evaluation.
