Compte de travail au jour le jour : Un filet de sécurité pour la flexibilité dans les projets de construction pétrolière et gazière
Dans le monde exigeant de la construction pétrolière et gazière, les circonstances imprévues et les modifications sont souvent la règle plutôt que l'exception. Pour accommoder ces changements inévitables, le concept de "Compte de travail au jour le jour" est utilisé. Cet article se penche sur les détails de ce mécanisme crucial, expliquant son objectif et comment il garantit une exécution fluide des projets.
Comprendre le Compte de travail au jour le jour
Un Compte de travail au jour le jour sert de méthode de paiement flexible pour les travaux qui ne figurent pas dans la portée initiale d'un contrat de construction. Ces travaux surviennent en raison de :
- Ordres de modification du propriétaire : Le propriétaire peut demander des travaux supplémentaires, des modifications ou des ajustements au cours du projet.
- Conditions imprévues du site : Des formations géologiques inattendues, des préoccupations environnementales ou des limitations du site peuvent nécessiter des ajustements au plan original.
- Modifications d'ingénierie : Des modifications de conception, de matériaux ou de spécifications pendant la construction peuvent déclencher des tâches supplémentaires.
Fonctionnement :
Le Compte de travail au jour le jour est généralement structuré sur une base de prix unitaire ou une approche « Coût majoré ».
- Prix unitaire : Cette méthode implique des tarifs préétablis pour la main-d'œuvre, les matériaux et l'équipement. L'entrepreneur facture au propriétaire les unités effectivement consommées pendant la journée de travail.
- Coût majoré : Dans ce cas, l'entrepreneur facture au propriétaire ses coûts réels, plus une majoration ou une commission prédéterminée pour les frais généraux et le profit.
Avantages des Comptes de travail au jour le jour :
- Flexibilité : Les Comptes de travail au jour le jour permettent des ajustements de projet sans entraver le progrès, car les entrepreneurs peuvent répondre rapidement aux changements et effectuer les travaux requis.
- Réduction du potentiel de litige : Des structures de prix prédéfinies minimisent les risques de litiges concernant les coûts et le paiement.
- Transparence : Des enregistrements détaillés des heures de travail, des matériaux et de l'utilisation de l'équipement offrent une transparence claire pour les deux parties.
Considérations et défis :
- Définition de la portée : Il est crucial de définir clairement les limites de la portée initiale pour éviter les litiges concernant ce qui constitue un travail au jour le jour.
- Contrôle des coûts : Tout en offrant de la flexibilité, les Comptes de travail au jour le jour nécessitent un suivi méticuleux des coûts pour éviter les dépassements de coûts.
- Documentation : Il est essentiel de tenir des registres détaillés de toutes les activités de travail au jour le jour pour une facturation précise et une justification des coûts.
Conclusion :
Les Comptes de travail au jour le jour sont des outils précieux pour naviguer dans la nature imprévisible des projets de construction pétrolière et gazière. En fournissant un mécanisme pour gérer les circonstances imprévues, ils favorisent l'efficacité et minimisent les retards. Cependant, une planification minutieuse, une communication claire et une documentation rigoureuse sont cruciales pour tirer parti des avantages de cette méthode de paiement tout en atténuant les risques potentiels.

Techniques
Day Work Account: A Comprehensive Guide for Oil & Gas Construction
This guide expands on the concept of Day Work Accounts in Oil & Gas construction projects, breaking down the topic into key chapters for better understanding.
Chapter 1: Techniques for Managing Day Work Accounts
Effective management of Day Work Accounts (DWAs) hinges on employing robust techniques across several areas:
1. Pre-Project Planning:
- Detailed Scope Definition: The initial contract should meticulously define the baseline project scope. This clarity is critical to differentiating between original contract work and work eligible for DWA. Using clear, measurable criteria and detailed drawings is essential.
- Pre-agreed Rates: Establish clear unit rates for labor (hourly rates categorized by skill level), materials (using a price book or index), and equipment (hourly rental rates inclusive of maintenance and fuel). These rates should be agreed upon before the project commences and documented in the contract.
- Change Order Process: A well-defined change order process is essential. This includes procedures for requesting, reviewing, approving, and documenting changes, along with timelines for each stage. This prevents ambiguity and disputes.
2. During Project Execution:
- Time Tracking: Implement a rigorous time tracking system to accurately record labor hours spent on DWA tasks. This might involve using time sheets, digital time clocks, or project management software.
- Material Tracking: Accurate tracking of materials used in DWA tasks is crucial. This requires detailed inventory management, receipts, and potentially barcoding systems.
- Equipment Tracking: Similar to material tracking, monitor equipment usage for DWA tasks, noting hours used, fuel consumption, and any maintenance needed.
- Daily Reports: Generate daily reports summarizing DWA activities, including labor hours, materials, equipment, and a brief description of work performed. These reports serve as the basis for billing.
- Regular Meetings: Hold regular meetings between the contractor and owner to review DWA progress, discuss any issues, and ensure alignment.
3. Post-Project Completion:
- Final Reconciliation: Conduct a thorough reconciliation of all DWA costs against the actual work performed. This involves verifying the accuracy of time sheets, material and equipment usage, and comparing it with the pre-agreed rates.
- Closeout Documentation: Comprehensive documentation is crucial. This includes all change orders, daily reports, invoices, and supporting documentation, necessary for audits and future reference.
Chapter 2: Models for Day Work Account Implementation
Two primary models are commonly used for structuring Day Work Accounts:
1. Unit-Price Method:
- This approach utilizes pre-negotiated unit prices for labor, materials, and equipment. The contractor bills the owner based on the actual quantities consumed during DWA activities.
- Advantages: Simplicity, transparency, and reduced potential for disputes due to pre-defined pricing.
- Disadvantages: Requires accurate forecasting of material and equipment needs; may not fully capture unforeseen complexities.
2. Cost-Plus Method:
- This method involves reimbursing the contractor for actual incurred costs (labor, materials, equipment) plus a predetermined markup percentage for overhead and profit.
- Advantages: Flexibility to accommodate unforeseen complexities; suitable for situations with high uncertainty.
- Disadvantages: Higher risk of cost overruns if not meticulously managed; requires a high degree of trust and transparency between contractor and owner.
Hybrid Approach: A hybrid model combining aspects of both unit-price and cost-plus can also be employed, tailoring the approach to specific DWA tasks.
Chapter 3: Software for Day Work Account Management
Various software solutions can streamline Day Work Account management:
- Project Management Software: Tools like Primavera P6, MS Project, or similar platforms can assist with scheduling, resource allocation, cost tracking, and change management related to DWAs.
- Time and Attendance Software: Software solutions specifically designed for tracking employee time and attendance improve accuracy and reduce manual errors.
- Inventory Management Software: This aids in tracking materials usage, minimizing waste, and improving the accuracy of material cost tracking in DWAs.
- Accounting Software: Integration with accounting software ensures accurate billing and financial reporting related to DWAs.
- Dedicated DWA Software: Some specialized software solutions are specifically designed for managing day work accounts, offering features tailored to the unique requirements of this process.
Choosing the right software depends on project size, complexity, and budget. Consider factors like integration with existing systems, user-friendliness, and reporting capabilities.
Chapter 4: Best Practices for Day Work Account Management
Successful DWA management requires adhering to best practices:
- Clear Communication: Maintain open and transparent communication between the contractor, owner, and relevant stakeholders throughout the project.
- Regular Monitoring: Closely monitor DWA costs against the budget and take corrective action promptly if overruns are identified.
- Robust Documentation: Maintain meticulous records of all aspects of DWA activities, including change orders, daily reports, invoices, and supporting documentation.
- Independent Verification: Consider engaging an independent quantity surveyor or cost engineer to verify the accuracy of DWA costs.
- Contingency Planning: Include a contingency budget within the overall project budget to accommodate potential DWA costs.
- Conflict Resolution Mechanisms: Establish clear procedures for resolving any disputes or disagreements that may arise regarding DWA activities.
Chapter 5: Case Studies of Day Work Account Implementation
(This section would include specific examples of projects where Day Work Accounts were used, highlighting both successes and challenges encountered. Real-world examples would demonstrate best practices and illustrate the impact of effective or ineffective DWA management. Due to the confidential nature of such projects, specific details would need to be obtained from relevant sources and anonymized to protect sensitive information.) For example, a case study might detail a project where unforeseen geological conditions led to significant DWA costs, but effective management and clear communication prevented major delays or disputes. Conversely, another case study could illustrate the negative consequences of poor DWA management, such as cost overruns and project delays.
