There are many theories about this, so here are my three cents...
[Disclaimer: I am the Product Manager for Spectrum. These comments are based on my work with clients over the years.]
First of all, it always depends on your facts and circumstances...as well as what your objectives are here. Here, the theory is that we are charging the job the costs of our ownership and operating costs that relate to the specific project.
The equipment rate we charge to jobs is comprised of two components:
- Ownership / Fixed Costs - Depreciation, License, Insurance, etc
- Operating / Variable Costs - Fuel, Repairs and Maintenance, etc
So if everything was the same, we would only have one set of charge rates. This is the starting point.
Based on the job though, we can opt to increase the operating/variable portion to cover the fuel surcharges. I have also seen folks increase the operating costs as the terrain is so difficult to work in that the asset has to be repaired and requires replacement parts.
Again, just my three cents.
What do others think here?
