Complete Guide to Price Escalation in France
•10 min read
Price adjustment in French public works contracts is regulated by the Code de la commande publique and the standard general conditions (CCAG-Travaux 2021). Learn the statutory rules, formulas, and INSEE indices.
1. Statutory & Regulatory Framework
Price revision is governed by articles L. 2112-2 and R. 2112-9 to R. 2112-18 of the French Public Procurement Code. It safeguards financial equilibrium against macroeconomic fluctuations during construction.
2. Core Rules and Contract Provisions
- • Mandatory Clause: Required on contracts longer than 3 months subject to material cost exposure.
- • Parametric Structure: P = P₀ [k + a(BT/BT₀) + b(TP/TP₀)...] with a fixed unadjusted share k ≥ 0.10.
- • Provisional Billing: When latest indices are pending, provisional coefficients are applied and settled upon publication.
- • Chorus Pro Format: Notes and billing schedules must provide clear index breakdowns for public accounting audits.
