#1 Project Size

In construction, there is a term called economies-of-scale.  The larger the framing project, the more efficient the contractor can be installing the framing.

#2 Location‍

The location where you are installing the framing will have a significant impact.  If you are installing the framing in downtown San Francisco the framing will obviously cost much more than the same framing being installed in Suburbia.

#3 Seasonality

‍Spring and Summer is peak framing season and Framing Contractors are generally swamped with work, so if you are getting a framing installed during this time you will likely pay a premium.
