Schedule Delay Analysis: Forensic Methods and Practical Applications

Add to Cart


The success of the schedule analysis will depend on a number of factors, including the quality of the schedules used to manage the project; the documentation available to identify and support delay causation; notice and mitigation efforts made during the course of the delay; plus a host of other factors. This has led to a number of different forensic schedule analysis methods employed by industry professionals and consultants to address the specifics of each delay situation. Because of the huge stakes as well as the expense of preparing, supporting or defending a delay claim, it’s important to select the method that is both appropriate to the circumstances and is most likely to provide the best outcome.

Part I. 

Schedule Delay Analysis — Choosing a Method and Why They Differ

There have always been debates and arguments over which delay analysis method is "the best method" to be used. Hundreds of articles have been published going back to the late 1960's. Which method is best is still a wide-open issue among schedulers, claim consultants, construction managers, contractors and attorneys.


The level of debate has increased in recent years since AACE International published their Recommended Practice — Forensic Schedule Analysis. What has not been widely discussed or written about is what factors should go into the decision-making process when choosing a delay analysis method for a particular project or a specific claim.


This 90-minute recorded webinar will get you answers to such pressing questions as:


  • How to choose a delay analysis method?
  • What are factors and issues should be addressed before committing to a potentially lengthy and expensive process?
  • Is the choice of delay analysis method irrevocable once made?
  • What are the risks of trying to change methods in mid-stream?

Our expert instructor, Jim Zack, provides answers and insights to these issues and highlights the 11 factors the scheduler should at least consider when making a choice.

Presented by James G. Zack, Senior Advisor, Ankura Construction ForumTM, and Patrick Kelly, Associate Director, Ankura Consulting Group

Generally good explanations of the various salient points that must be considered, prior to moving to the proper schedule delay methodology.

Part II. 

Schedule Delay Analysis — Observational Methods — Static & Dynamic Logic

Like engineering, CPM scheduling is both an art and a science. CPM scheduling delay analysis techniques allow the analyst to distinguish critical delays from non-critical delays and calculate their impact on the project duration, identify concurrent delays that did or would have delayed the project completion and differentiate between concurrent and pacing delay. When choosing a method there are a number of technical, practical and legal considerations that a delay analyst makes.


This presentation focuses on those methodologies referred to in the industry as "observational" methods. It explores the performance of a credible delay analysis and identify many of the strengths and pitfalls of these methodologies.


This recorded webinar program will help you:


  • Understand and distinguish between the forensic schedule analysis observational methodologies
  • Become familiar with the use of the observational methodologies, such as the As-Planned vs. As-Built, and the Contemporaneous Period Analysis (often called "windows")
  • Discover the various enhancements to the As-Planned vs. As-Built that will improve an analysis beyond a "total time" analysis
  • Learn about the different types of Contemporaneous Period Analyses, and understand the difference between losses (or gains) due to progress and those due to changes to the schedule
  • Identify the strengths and pitfalls of the observational methodologies

Presented by Scott Lowe, Trauner Consulting Services

Very informative.

The speaker was well versed in what works and what doesn't work for forensic scheduling, something that you learn by hands-on experience. I appreciate listening to a lessons-learned talk.

Part III. 

Schedule Delay Analysis — Modeled Methods — Additive & Subtractive

The time for performance of a project is usually of the essence to the employer and the contractor. This has made it quite imperative for contracting parties to analyze project delays. A major source of the disputes lies with the limitations and capabilities of the techniques in their practical use.


Hence it is imperative that both owners and contractors develop an understanding of delay measuring methods along with advantages and disadvantages of each. Because it’s known that various methods give different allocations of delay responsibilities when applied to the same set of delay claims data, reinforcing the common notion that the most appropriate technique for any claims situation depends on the claims circumstances and the project.


The different results stem mainly from the unique set of requirements and application procedures each technique employs. This presentation focuses on those methodologies referred to in the industry as "modeled" methods. It explores the performance of a credible delay analysis and identify many of the strengths and pitfalls of these methodologies.


This informative recorded program will help you:


  • Understand and distinguish between the forensic schedule analysis modeled methodologies
  • Become familiar with the use of the modeled methodologies that "add" activities to the schedule to model events, such as the Impacted As-Planned and the Retrospective TIA
  • Discover the nature of the Impacted As-Planned, the limited circumstances in which one can implement such an analysis, and the difficulties in doing so
  • Review the uses, benefits, and problems with implementing a Retrospective TIA, including the contractual reasons why one may be necessary
  • Learn about the use of the modeled methodologies that “subtract” activities from the schedule to create a “but for” view of a project — commonly called the Collapsed As-Built
  • Identify the strengths and pitfalls of the Collapsed As-Built

Listen to our scheduling expert to learn more about the fascinating topic of risk-adjusted schedules for both improved project management as well as potential delay analysis applications.

Part IV. 

Forensic Schedule Analysis & Discretionary Logic

Let’s face it: Forensic Schedule Analysis (FSA) and real time schedule review do not handle CPM schedules with significant amounts of discretionary logic very well. While major theoretical and practical advancements have been made on what FSA methodology is most appropriate to evaluate schedule delay in the last decade, largely through the introduction of AACE's RP29R-03, the role of discretionary logic often is poorly addressed.


Nevertheless, discretionary logic — the type of logic that is not dictated by either the contract or the physical necessity of the project — continues to cause difficulty for fair and accurate analysis of schedule updates during the course of the project in the construction industry. Further, these analytical problems persist in the methodologies associated with post-construction FSA.


This recorded presentation highlights several applications and refinements of existing forensic delay methodologies, particularly As-Planned vs. As-Built, Contemporary Period Analysis and Collapsed As-Built, which can assist in identifying the as-built critical path and delay responsibility in projects with significant amounts of discretionary logic.


Listen to this information-packed session to:


  • Understand the basics of the major forensic delay methodologies
  • Gain information on the role of discretionary logic in CPM schedules
  • Discover how to consider and address discretionary logic in forensic applications
  • Identify which FSA methodologies can address discretionary logic with little problem
  • Determine how to adapt some methodologies to appropriately address discretionary logic
