Abstract: With the variety of Delay Analysis Techniques available to schedule reviewers and analysts, it is difficult to know and implement the most reliable and effective way of demonstrating an accurate impact calculation caused by delay. Contractual requirements for time extension requests using the common term, “Time Impact Analysis”, are increasingly appearing throughout the construction industry. The AACE International’s Recommended Practices (29R-03) lists nine (9) different analysis methods that are commonly labeled as “Time Impact Analysis”. While each methodology may have its appropriate implementation, certain methodologies can be combined to produce a more reliable and accurate result. In the following paragraphs the Fixed Perspective Windows Delay Analysis (“Analysis”) method will be presented, which incorporates the strengths of various retrospective methods, while minimizing, if not alleviating the weaknesses. The result is an analysis that, when prepared correctly, is simple to calculate and easy to defend.
