There are written numerous book on cost estimation (e.g. Plant design and economics for chemical engineers" by .

The estimations evovles a breakdown of activities, etsimation for each activity - and is dependant on the level of accuracy that you are moving in.

Try to seach for book on the subject - IMHO its to broad for this forum.
