Contingency

Contingency is a buffer amount (a percentage of cost) added to an estimate to cover the unknowns that show up on almost every job.

Contingency isn't padding — it's a realistic allowance for conditions you can't fully predict at bid time. Burying it instead of pricing it is how unforeseen costs turn into lost margin.
