How the calculation works
Total = area × mode-specific rate + egress + water control + contingency.
What to verify
Excavation depth, underpinning, utility relocation and local code can dominate actual cost.
How accurate is this calculator?
It is a transparent planning calculation based on the entered values and stated assumptions. Verify inputs and obtain professional or supplier confirmation where the decision is consequential.
Does it use U.S. defaults?
Yes. U.S. units, terminology, pricing conventions and rules are the primary defaults where location matters.
Is data sent to a server?
No. The calculation runs locally in the browser and does not send entered values to a remote calculation service.
