Windows Analysis

In this video, we continue our in-depth exploration of delay analysis methods with a focus on Windows Analysis— one of the most reliable and widely used techniques for forensic schedule assessments. Unlike prospective methods such as Impacted As-Planned and Time Impact Analysis (TIA), Windows Analysis is a retrospective approach, analysing actual project updates to determine the real impact of delay events.

Key Topics Covered:

  • The Fundamentals of Windows Analysis: Learn why this method is recommended by the Society of Construction Law (SCL) Delay & Disruption Protocol for accurate and fact-based delay assessments.
  • How It Works: Discover how to divide the project into time windows and assess delays based on real progress updates rather than theoretical predictions.
  • Practical Application: See a detailed Primavera P6 demonstration, where we analyse a Substructure & Superstructure project using Windows Analysis. Through multiple time windows, we evaluate delay events affecting the project’s completion date.
  • Comparative Analysis: Understand how Windows Analysis differs from TIA and Impacted As-Planned, highlighting its strengths in resolving construction claims and dispute resolution.
  • Practical Application in Primavera P6 – A real-world case study demonstrating how Windows Analysis helps determine time extension and cost entitlements.

Windows Analysis is particularly valuable for projects where accurate record-keeping and real progress tracking are essential. By examining actual project updates, this method ensures that delay assessments are objective, transparent, and defensible in legal disputes.
