estimating framing costs
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.
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.
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.
Framing Contractors will generally provide an all inclusive bid to provide all labor, materials and equipment to install the wood framing.
Here is an example of how to write a Scope of Work that insures your Framing Contractor provides an all-inclusive bid.
All Framing work is to be Contractor Furnished, Contractor Installed.
