FAQ

Common questions

Why include contingency?

Contingency covers unknowns like rework, small scope changes, or delivery fluctuations that often happen in real projects.

Can I compare contractor quotes with this?

Yes. Enter each quote as a separate run to compare total projected cost with the same contingency logic.
