Is there a standard for converting CSI codes into costs?
Where would I find the codes for this standard if it exists?
Is it unusual to ask for project costs broken down by CSI code.
It is done all the time use masterformat to set up your sections by CSI sections. Go to masterformat.com and download the free 2010 update. You can break you estimate down by broad sections or can go into more narrow sections depending on how detailed you want to go.
