French Construction Delay Penalty Calculator
Contract amount and days late: calculate the delay penalty using the CCAG Travaux default formula (V × R / 3000), with an optional cap and a day-by-day progression.
Override only if your CCAP sets a different rate.
Leave blank for the CCAG Travaux 2021 cap of 10% (with the default rate); enter 0 if your contract sets no cap.
This calculation comes back with every progress statement. Mirage prepares it.
Mirage builds your monthly progress statement (situation de travaux) from the DPGF and site progress, every line traced to its source. Send us a past statement and we send back a plan, no commitment.

Frequently asked questions
By default on a French public works contract, the CCAG Travaux (article 19.2) applies a daily penalty equal to the contract's amount excl. VAT divided by 3000, multiplied by the number of days late: P = V × R / 3000. This rate only applies if the CCAP (the contract's specific administrative clauses) doesn't set a different one, this calculator lets you override the divisor if yours does.
It's the default rate under the CCAG Travaux for public works contracts. On a private contract, whatever penalty clause is written into the contract applies, it often follows the same formula by convention, but nothing requires it. Always check the CCAP or the signed contract.
Yes, on a public works contract under the CCAG Travaux 2021: article 19.2.2 caps the total delay penalties at 10% of the contract amount excl. VAT (or of the tranche or purchase order), and article 19.2.1 exempts the contractor when the total penalty for the whole contract does not exceed 1,000 euros excl. VAT. This calculator applies both when you keep the default rate and enter no cap of your own. The CCAP can set a different cap: enter it to see when it would be reached, or 0 if the contract sets none.
No formal notice (mise en demeure) is needed, but the CCAG Travaux 2021 adds an adversarial step (article 19.2.4): before applying the penalties the project supervisor (maître d'œuvre) recorded, the client must invite the contractor in writing to present its observations within at least fifteen days, stating the amount considered and the delays concerned. If the contractor does not answer, or does not show that the delay is not its fault, the penalties apply, counted from the day after the contractual deadline expired. A private contract may set a different procedure: check its clauses.
A delay penalty means a schedule already slipped. Mirage helps construction companies bidding on French projects track progress and contractual deadlines before delay turns into a bill.
