Cost of production plant
If you are looking for data on costs for production plants you might consider the BLS productivity data https://www.bls.gov/mfp/mprdload.htm.

Under the combined sector and industry multifactor productivity excel file you can find cost measures organized by NAICS (North American Industry Classification System) at the three digit level [https://www.census.gov/cgi-bin/sssd/naics/naicsrch?chart=2012] .    

Depending on what type of production plant you are looking for there is data by energy usage, rent, and other types of costs.
