Dans le monde dynamique du pétrole et du gaz, les projets rencontrent souvent des défis imprévus et des changements de portée. Bien que ces ajustements soient inévitables, ils peuvent créer un paysage financier complexe, en particulier lorsque les coûts n'ont pas été définis de manière définitive. C'est là que le terme Travaux Autorisés Non Définis (TAND) entre en jeu.
Que sont les Travaux Autorisés Non Définis ?
Les TAND font référence à tout changement de portée pour lequel l'autorisation de procéder a été accordée, mais dont les coûts estimatifs sont encore en négociation ou n'ont pas été finalisés. Essentiellement, cela signifie que le travail est approuvé pour commencer, mais que le prix reste incertain.
Pourquoi les TAND surviennent-ils ?

Chapter 1: Techniques for Managing Authorized Unpriced Work (AUW)
This chapter explores practical techniques for managing AUW, focusing on minimizing risks and ensuring efficient project execution.
1.1 Proactive Scope Definition: The most effective technique for mitigating AUW is to meticulously define the project scope upfront. This involves thorough site investigations, detailed engineering designs, and comprehensive risk assessments to anticipate potential variations. Employing techniques like Work Breakdown Structures (WBS) and robust change management processes are crucial.
1.2 Contingency Planning: Incorporating a contingency buffer within the initial project budget specifically addresses unforeseen circumstances. This buffer accounts for potential AUW and allows for flexibility without significantly disrupting the overall financial plan. The size of the contingency should be determined through risk analysis.
1.3 Early Warning Systems: Implementing systems for early identification of potential scope changes is critical. Regular progress meetings, site inspections, and proactive communication between all stakeholders can help to identify potential AUW early, enabling timely intervention and mitigation.
1.4 Timely Cost Estimation: Even when AUW is unavoidable, obtaining accurate and timely cost estimates is paramount. This requires close collaboration with contractors, leveraging their expertise and experience. Techniques like parametric estimating and analogy estimating can provide reasonably accurate cost approximations.
1.5 Change Control Board (CCB): Establishing a formal CCB to review and approve all proposed scope changes is essential. This ensures a structured process for evaluating the necessity, impact, and cost implications of AUW before authorization. The CCB should include representatives from various stakeholders.
1.6 Regular Monitoring and Reporting: Continuous monitoring of AUW through regular reports and financial tracking is necessary. This ensures that the accumulated cost of AUW remains within acceptable limits and allows for timely corrective action if needed.
