On the other hand stochastic, or random, processes deal with many possible outcomes of the same project by exploring different probabilities and likelihoods of the duration of each activity and, ultimately, how the project might evolve over time. Stochastic processes result in completion date probability distributions (how often each completion date is calculated) based on a random selection of the likelihoods and probabilities based on risk durations defined by the project team. Once the baseline is set, the process assists the project management team by identifying which outcomes are more probable than others.

13 has a total float of 7 days, but a free float of 0 days. This is because if Activity 140 slipped by 1 day, it would decrease the amount of float available to its successor activity, which also has 7 days of total float. 1, with the critical path indicated in bold font. Total float (TF) is the amount of time that the start or finish of a task can be delayed without extending the project’s overall duration, or delaying the completion of the project’s final activity. Total float is equal to the difference between each task’s LF and its EF (or its LS and ES).

Understanding these relationships is essential when using any of the commercially available CPM software applications. 7. 7 are explained as follows: • • • • finish-to-start – Task B cannot start until Task A has finished finish-to-start with lag – Task B cannot start until ‘d’ days have elapsed after Task A has finished start-to-start – Task B cannot start until Task A has started finish-to-finish with lag – Task B cannot finish until ‘d’ days have elapsed after Task A has finished. 28 Delay Analysis in Construction Contracts The ‘d’ periods represented above are referred to as ‘lags’.
