As-Built Schedule: Reconstructing Reality in Oil & Gas Projects

The world of oil and gas projects is complex, dynamic, and often fraught with unexpected challenges. While meticulous planning is crucial, unforeseen circumstances, such as weather delays, equipment failures, or regulatory changes, frequently derail the original schedule. This is where the "As-Built Schedule" becomes a powerful tool, offering a clear picture of how the project actually unfolded.

What is an As-Built Schedule?

An As-Built Schedule is a reconstruction of the project schedule that accurately reflects the sequence and durations of tasks as they were actually completed. It acts as a historical record of the project's execution, capturing the deviations from the original plan.

Key Features of an As-Built Schedule:

  • Actual Start and Finish Dates: The As-Built Schedule pinpoints the precise dates when tasks commenced and concluded, highlighting any delays or advancements.
  • Updated Task Durations: It adjusts the originally planned durations of tasks to reflect the actual time taken for their completion.
  • Critical Path Analysis: By identifying the critical path, the As-Built Schedule reveals the tasks that most directly impact the project's overall completion date.
  • Delay Analysis: It provides valuable insight into the reasons for delays, including:
    • Excusable Delays: Situations beyond the contractor's control, such as natural disasters or unforeseen site conditions.
    • Non-Excusable Delays: Delays attributable to the contractor's actions or omissions.

Why is the As-Built Schedule Important in Oil & Gas Projects?

  • Claim Analysis: When a contractor seeks extra compensation for delays or changes, the As-Built Schedule serves as a crucial document to support their claims. It demonstrably shows how the project's timeline deviated from the original plan and provides a basis for calculating potential costs.
  • Lessons Learned: Analyzing the As-Built Schedule allows stakeholders to identify areas of inefficiency, communication breakdowns, or unforeseen challenges. These insights are invaluable for improving future project planning and execution.
  • Risk Management: By understanding the factors that impacted the project's schedule, organizations can develop more robust risk mitigation strategies for future endeavors.
  • Contractual Compliance: The As-Built Schedule ensures adherence to contractual obligations, including completion deadlines and specific performance criteria.

Creating an As-Built Schedule:

  • Collect Accurate Data: This involves gathering information from various sources, including timesheets, daily reports, and progress updates.
  • Analyze the Data: This involves identifying the sequence of tasks, their durations, and any interruptions or delays that occurred.
  • Document the Differences: The As-Built Schedule highlights the discrepancies between the original schedule and the actual execution, providing a clear picture of the project's evolution.

Conclusion:

In the demanding world of oil and gas projects, the As-Built Schedule plays a vital role in ensuring transparency, accountability, and effective decision-making. It empowers stakeholders to understand the project's reality, analyze potential claims, and learn valuable lessons for future endeavors. By accurately reflecting the project's true course, the As-Built Schedule serves as an essential tool for navigating the complexities of oil and gas development.

Exercise: Analyzing an As-Built Schedule

Scenario: You are a project manager reviewing the As-Built Schedule for an oil well drilling project. You notice the following:

  • The original schedule estimated a drilling duration of 30 days.
  • The actual drilling duration was 45 days.
  • The delay was caused by a faulty drilling bit that required replacement.

Task:

  1. Identify the type of delay (excusable or non-excusable).
  2. Explain why this delay is excusable or non-excusable.
  3. Suggest a potential action to mitigate similar delays in future projects.

Exercise Correction

1. **Type of Delay:** Excusable Delay. 2. **Explanation:** The delay was caused by a faulty drilling bit, which is considered an unforeseen equipment failure. This is beyond the contractor's control, making it an excusable delay. 3. **Mitigation Action:** Implementing a rigorous equipment inspection and maintenance program before drilling operations can help identify potential issues with drilling bits and prevent future delays.
