SOS!! White Wood

[vishbin]

Hi Estimators,

Can any one tell me the total cost of White Woods (Ribs, Runners, etc.) for a project. I.e., I was looking for some thumb-rules as follows -

1. (White Woods Cost) / (Total Project Cost)

OR

2. (White Woods Cost) / (Total Shuttering Cost)

Thanks in advance. Cheers
