Hi Kumar,
More info are required to naswer your question, indeed, steel erection ratio will not be the same for erection of stick-built structure or prefabricated pipe rack; manually cable pulling or with electrical winch, piping erection is also function of location (inside unit or on racks)... ... Maybe you can detailed your request
In addition, this will also be impacted by the country, either you know the local average productivity factor or you may need to adapt the ratio based on local feedback.
Also, did you look at the rates part of this site, it may contains some.
Rgds,
Maxime.
