What is delay analysis?

Delay analysis or schedule delay analysis is the investigation and research of an event, executed with the objective to pin down the reason for a project delay.  Anvelo can help you in delay analysis for all industries.  We specialise in delay analysis for the construction industry.

Delay analysis is the process of investigating events using the CPM (critical path method) scheduling methods.  This helps in finding the exact cause and extent of delays in a project with focus on the critical path.  This can then be used to resolve the delay claims through legal proceedings or negotiations.

The first step involves carefully examining facts, contemporaneous records, programs and any other reliable sources of information. All information is then considered in its entirety by an experienced professional or team of professionals. 

Anvelo will confidently carry out these fact-finding exercises, to then apply an appropriate method of delay analysis in order to model the effects of an event. Each delay will then be crystalised based on its cause and effect(s). 

This will be done in simple circumstances where there are one or few events. Alternatively, it will be carried out on more complicated matters, where there are tens or even hundreds of events that have taken place.

How is it used in construction?

In construction forensic schedule delay analysis is used for the investigations of assignments and activities by using the CPM( Critical Path Method) scheduling methods to model the real project state to resolve any delay claims through legal affairs or by negotiations.

There are a number of methods used to quantify delays that occurred during a project.
The most used methods are as follows:

  • Impact as-planned
  • Collapsed as-built
  • As-planned vs as-built
  • Time impact analysis
  • Window analysis

Every Forensic Delay Analysis method has its own pros and cons. The selection of methods to quantify the delays should be based on prior analyses and complete understanding of the project.

Forensic Delay Analysis can also answer the following questions:

  • How late is the project?
  • What has caused the project to delay?
  • Who is responsible for the delay?
  • What is the cost impact of the delay?
  • Is this a concurrent delay?
  • And more

Types of forensic delay analysis methods

The collapsed as-built analysis is very easy to understand and can be influenced with the introduction of after-the fact logic and delay events. It does not need an as-planned schedule of contemporaneous schedule updates. It is the opposite of an impacted as-planned analysis. The method starts by removing delay events from the as-built schedule to find exactly when the project should have been completed for the delay events.

This is the most accurate method for projects with short terms and one plain critical path. As the name suggests, this method is the comparison of the baselines or as-planned and as-built schedules or a schedule update reflecting progress. This method compares planned vs the actual dates on the as-planned critical and near-critical paths. The method compared draft start date and finish date vs the confirmed start date and finish date.

The time impact analysis (TIA) is a comprehensive technique and it is considered as a hypothetical model as it does not rely on as-built data. It can be quick and easy to perform as it does not require an as-built schedule. If there are a large number of delay events, this method can be overwhelming to perform. In this method each delay event has to be analysed individually in sequential order to help compute their impact. Each delay is quantified immediately before and after the delay event happens.

The windows analysis method compared to others is time-consuming and requires full project documentation and depends on as planned and as built schedule particulars. It is a retrospective technique which divides the total project duration into windows (Smaller periods) and quantifies the as-built critical path delays for each of these periods. It compares the baseline to the as built schedules in their as-is state of submission. It can be easy to compute and understand, it helps to spot delays using real time conditions and true construction processes.
