Provisional Sum

Sommes Provisionnelles : Gérer l'Incertitude dans les Contrats Pétroliers et Gaziers

Dans le monde complexe et en constante évolution des projets pétroliers et gaziers, les incertitudes sont inévitables. Des conditions de marché fluctuantes aux défis imprévus sur le site, ces variables peuvent avoir un impact significatif sur les coûts du projet. Pour répondre à ces inconnues, les contrats utilisent souvent une disposition appelée "Somme Provisionnelle".

Qu'est-ce qu'une Somme Provisionnelle ?

Une Somme Provisionnelle est un montant spécifique d'argent inclus dans un contrat à prix fixe. Elle représente une allocation pour des éléments de dépenses connus, mais pour lesquels des détails suffisants ne sont pas disponibles au moment de l'appel d'offres pour estimer un prix précis. Ce manque de détails peut provenir de divers facteurs, tels que:

  • Incertitudes de conception : L'étendue exacte des travaux peut ne pas être entièrement définie pendant la phase d'appel d'offres, laissant place à des ajustements ultérieurs.
  • Fluctuations des matériaux : Les prix de certains matériaux, en particulier les équipements spécialisés, peuvent fluctuer considérablement, ce qui rend difficile la prédiction précise de leur coût.
  • Contingences : Des circonstances imprévues, comme des conditions de site inattendues ou des changements dans les exigences réglementaires, peuvent survenir pendant le projet, nécessitant des fonds supplémentaires.

Pourquoi utiliser des Sommes Provisionnelles ?

Bien qu'une somme provisionnelle introduise un degré de flexibilité dans un contrat à prix fixe, son inclusion n'est pas arbitraire. Elle sert plusieurs objectifs importants:

  • Gestion des risques : Elle permet à l'entrepreneur de tenir compte des augmentations de coûts potentielles sans avoir recours à des ordres de modification coûteux et chronophages plus tard.
  • Précision du budget : En incorporant une somme provisionnelle, le budget global du projet devient plus réaliste et atteignable, en tenant compte des incertitudes potentielles.
  • Chronogramme du projet : Elle permet d'éviter les retards causés par des litiges sur des coûts imprévus ou des changements de portée.

Comment fonctionnent les Sommes Provisionnelles

La libération d'une somme provisionnelle est généralement à la discrétion de l'architecte ou de l'ingénieur superviseur. Le processus implique:

  1. Définition détaillée de la portée : Une fois que les spécificités des travaux nécessitant la somme provisionnelle sont mieux définies, l'entrepreneur soumet une proposition détaillée pour les travaux.
  2. Évaluation et approbation : L'ingénieur superviseur examine la proposition de l'entrepreneur et détermine si les fonds demandés se situent dans la limite de l'allocation de la somme provisionnelle initiale.
  3. Libération des fonds : Si la proposition est approuvée, les fonds alloués sont libérés à l'entrepreneur pour exécuter les travaux comme spécifié.

Considérations clés pour les Sommes Provisionnelles :

  • Transparence et communication : Il est crucial de définir clairement la portée et le but de chaque somme provisionnelle dans le contrat pour garantir la transparence et éviter les litiges potentiels.
  • Allocation adéquate : La somme doit être suffisante pour couvrir la fourchette de coûts potentiels associés à l'élément incertain, ce qui évite de devoir demander des fonds supplémentaires pendant le projet.
  • Examen régulier : Des examens périodiques de l'allocation de la somme provisionnelle doivent être effectués pour s'assurer de sa pertinence et de son adéquation continues au fur et à mesure que le projet progresse.

Conclusion :

Les Sommes Provisionnelles sont un outil précieux pour gérer les incertitudes inhérentes aux projets pétroliers et gaziers. En les incorporant dans les contrats, les parties prenantes peuvent atténuer les risques, améliorer la précision du budget et garantir le respect des échéances du projet. Une communication claire, un examen approfondi et une approche collaborative sont essentiels pour garantir l'utilisation réussie des sommes provisionnelles, maximisant ainsi leurs avantages pour toutes les parties impliquées.
