My friend, I can tell you from experience; the analyses are already done.
When someone calculates a large civil (read dirt) project and it involves transporting material they are responsible for, there is a calculation on how many people you will kill by driving trucks on streets, freeways etc.
Statistically, you will kill someone at some point, and will be responsible for that payout. So that payout is included in the estimate to complete the project.
They don't list it in the bid as "killed people" mind you. It is under their "Builder's Risk" section from which they will take out insurance.
