Definition of an Impacted Programme
An Impacted Programme is a modified version of the original project schedule that incorporates the effects of identified delays, disruptions, or changes. It reflects how the project timeline has been affected by various impacts and is used to assess the extent of delays and their effects on the overall project completion date.
Purpose of Preparing an Impacted Programme
- Delay Analysis:
- Quantify Delays: To determine the total amount of delay caused by specific events or disruptions.
- Assess Impact: To evaluate how delays impact the project’s critical path and overall completion date.
- Claim and Dispute Resolution:
- Support EOT Claims: To provide evidence and justification for an Extension of Time (EOT) claim in response to delays caused by external factors.
- Resolve Disputes: To offer a clear, evidence-based view of how delays have affected the project, aiding in negotiations and dispute resolution with clients or contractors.
- Schedule Adjustment:
- Update Project Timelines: To revise and adjust the project schedule based on actual progress and delays.
- Plan for Recovery: To identify and plan recovery actions or acceleration measures to mitigate delays and return the project to its original timeline or as close to it as possible.
- Communication:
- Inform Stakeholders: To provide stakeholders, including clients, subcontractors, and project managers, with an updated view of the project schedule and its current status.
- Document Changes: To document the impacts and changes to the project schedule for future reference and historical record.
- Project Management:
- Manage Resources: To adjust resource allocation and management strategies based on the updated timeline.
- Improve Controls: To enhance project controls and monitoring by reflecting actual progress and delays in the updated programme.
How to Prepare an Impacted Programme
- Identify Impacts:
- Gather information on delays, disruptions, or changes that have affected the project schedule.
- Categorize the impacts (e.g., weather, design changes, site conditions).
- Update the Baseline Schedule:
- Modify the baseline schedule to include the effects of the identified impacts.
- Adjust the start and finish dates of affected activities based on actual progress and delays.
- Recalculate the Critical Path:
- Determine the new critical path by incorporating the delays into the updated programme.
- Assess how delays have shifted the project’s critical path and completion date.
- Analyze the Impact:
- Quantify the total delay and its effect on the project’s completion date.
- Identify any new critical activities or changes in project milestones.
- Document and Communicate:
- Prepare a detailed report or presentation outlining the changes, impacts, and revised schedule.
- Communicate the updated programme to all relevant stakeholders.
Example Scenario
Project Name: XYZ Office Building Construction
Original Baseline Completion Date: December 31, 2024
Identified Delay: Adverse weather conditions during August 2024 led to a 15-day delay in façade installation.
Steps:
- Impact Identification: Record the delay in façade installation due to weather conditions.
- Update Schedule: Adjust the façade installation activity in the baseline schedule to reflect the 15-day delay.
- Recalculate Critical Path: Determine the new critical path and revised completion date.
- Document Impact: Prepare an impacted programme showing the adjusted schedule and extended completion date.
Outcome:
- Revised Completion Date: February 14, 2025 (a 15-day delay from the original date).
- Report: Detailed report highlighting the delay, impact on the schedule, and the revised completion date.
Preparing an impacted programme is crucial for effective project management, enabling stakeholders to understand the effects of delays and disruptions on the project’s timeline and ensuring that appropriate measures are taken to address and mitigate these impacts.
