In the dynamic and often complex world of oil and gas project management, accurate documentation is paramount. One crucial document, the As-Built Schedule, plays a vital role in capturing the reality of project execution. Unlike the initial project schedule, which outlines planned milestones and durations, the As-Built Schedule reflects the actual progress of the project, providing a clear picture of how the project unfolded.
What is an As-Built Schedule?
An As-Built Schedule is a comprehensive document that details the final project schedule, incorporating actual completion dates, durations, and start dates for each task or activity. It serves as a historical record of the project's actual execution, highlighting deviations from the initial plan and providing valuable insights for future projects.

Conclusion:
The As-Built Schedule is a powerful tool for oil and gas project management. By capturing the actual execution of the project, it provides valuable insights for evaluation, future planning, and contractual purposes. Investing in the creation and maintenance of a robust As-Built Schedule ensures a comprehensive understanding of project performance and facilitates informed decision-making for future endeavors.

Scenario: You are working on an oil & gas drilling project. The initial project schedule outlined a 10-day drilling operation. However, due to unforeseen geological conditions, the drilling took 15 days to complete.
Task: Create a basic As-Built Schedule for the drilling operation, outlining the following:
Exercise Correction:
**As-Built Schedule: Drilling Operation** | Task | Actual Start Date | Actual Finish Date | Actual Duration | Dependencies | Resources | Notes | |---|---|---|---|---|---|---| | Drilling Operation | May 1st | May 15th | 5 days | Completion of wellhead construction | Drilling rig, crew of 10, specialized drilling tools | Unforeseen geological conditions extended the drilling time. |
Creating an accurate and useful As-Built Schedule requires a systematic approach. Several techniques can ensure the final document is comprehensive and reliable:
1. Regular Data Collection: The cornerstone of an effective As-Built Schedule is consistent data collection. This should involve daily or weekly updates reflecting actual start and finish times for each task. Dedicated personnel should be responsible for this, using standardized reporting methods.
2. Automated Tracking Systems: Employing project management software (discussed in Chapter 3) significantly aids data collection and reduces manual effort. Automated systems can track progress automatically, reducing the risk of human error and omissions.
3. Progress Meeting Documentation: Minutes from project progress meetings should explicitly record schedule updates, deviations, and reasons for delays or accelerations. These minutes become crucial supporting documentation for the As-Built Schedule.
4. Change Management Integration: All changes to the original schedule—whether scope changes, resource reallocations, or unforeseen delays—must be meticulously documented and incorporated into the As-Built Schedule. A formal change management process is essential.
5. Variance Analysis: Regularly comparing the planned schedule to the actual progress allows for early identification of potential problems. This variance analysis informs decision-making and ensures timely adjustments.
6. Visual Aids: Employing Gantt charts, network diagrams, or other visual representations alongside tabular data makes the As-Built Schedule easier to understand and interpret for stakeholders.
7. Stakeholder Collaboration: Involving key stakeholders in the process of updating and verifying the As-Built Schedule ensures buy-in and accuracy. Regular feedback loops prevent inconsistencies and discrepancies.
Various models can be used to represent the As-Built Schedule, each with its own strengths and weaknesses. The choice depends on project complexity and stakeholder preferences:
1. Gantt Chart: A widely used visual representation showing tasks against a timeline. An As-Built Gantt chart clearly illustrates actual start and finish dates, deviations from the planned schedule, and task dependencies.
2. Network Diagram (CPM/PERT): These models graphically depict task dependencies and critical paths. In the As-Built context, they highlight which activities caused delays or impacted project completion.
3. Spreadsheet Model: While less visually appealing, spreadsheets offer flexibility and allow for detailed data recording, including resource allocation, costs, and specific notes for each task.
4. Hybrid Models: Often, a combination of models is used. For example, a high-level Gantt chart might accompany a detailed spreadsheet, providing a comprehensive overview and granular details.
5. Earned Value Management (EVM): While not a scheduling model itself, EVM integrates with scheduling data to provide a comprehensive picture of project performance, including schedule variance and cost performance.
The selected model should be readily understandable and usable by all project stakeholders.
Several software solutions facilitate the creation and management of As-Built Schedules:
1. Primavera P6: A leading project management software offering robust scheduling capabilities, including baseline comparison and progress tracking, making it ideal for creating detailed As-Built Schedules.
2. Microsoft Project: A more accessible option with built-in Gantt charting and task management features, suitable for smaller projects.
3. Asta Powerproject: Another popular choice for project management, offering a range of features suitable for creating and managing As-Built Schedules, particularly in complex projects.
4. Other specialized software: Industry-specific software tailored to the oil and gas sector may integrate directly with operational data systems, streamlining data collection and analysis for As-Built Schedule creation.
The choice of software depends on project size, complexity, budget, and existing infrastructure. The selected software should seamlessly integrate with other project management tools.
Implementing best practices ensures the As-Built Schedule is accurate, reliable, and provides maximum value:
1. Establish a Clear Process: Define a standardized process for data collection, reporting, and updating the As-Built Schedule from the project's outset.
2. Regular Updates and Verification: Frequent updates are crucial, ideally daily or weekly, to maintain accuracy. Regular verification with project data ensures the schedule accurately reflects reality.
3. Document All Changes: Meticulously record all schedule changes, including reasons for deviations, resource adjustments, and scope modifications. Maintain an auditable trail of all changes.
4. Assign Responsibilities: Clearly assign roles and responsibilities for data collection, updating, and verification of the As-Built Schedule.
5. Utilize Version Control: Implement a system for version control, allowing tracking of changes and providing access to previous versions.
6. Secure Storage and Access: Store the As-Built Schedule securely and ensure authorized access only to relevant stakeholders.
7. Post-Project Review: After project completion, conduct a thorough review of the As-Built Schedule to identify lessons learned and improve future project planning.
