Exercise: Calculating Finish Float

Scenario:

You are working on an oil and gas project with the following activities:

• Activity A: Design and Engineering (Estimated duration: 10 days)
• Activity B: Procurement (Estimated duration: 5 days, depends on Activity A)
• Activity C: Construction (Estimated duration: 15 days, depends on Activity B)

The early start date for Activity A is Day 1.

Task:

1. Calculate the early finish date for Activity A.
2. Calculate the early start and early finish dates for Activity B.
3. Calculate the early start and early finish dates for Activity C.

Techniques

Chapter 1: Techniques for Calculating Finish Float

This chapter dives into the practical methods used to calculate finish float in oil and gas projects.

1.1 Critical Path Method (CPM):

The foundation of finish float calculation lies in the CPM. This technique maps out all project activities, their dependencies, and estimated durations. CPM identifies the critical path - the sequence of activities with the least amount of float.

1.2 Forward and Backward Pass:

CPM utilizes two passes to determine the earliest and latest start and finish times for each activity:

• Forward Pass: Calculates the earliest start and finish times, assuming activities start as soon as possible.
• Backward Pass: Calculates the latest start and finish times, assuming activities start as late as possible without delaying the project completion.

1.3 Formula for Finish Float:

Finish Float is calculated as the difference between the late finish time of an activity and its early finish time.

Finish Float = Late Finish - Early Finish

1.4 Types of Float:

• Free Float: The amount of time an activity can be delayed without impacting its successor activity.
• Total Float: The maximum time an activity can be delayed without delaying the project completion date.
• Independent Float: The time an activity can be delayed without affecting its predecessors or successors.

1.5 Software Tools for CPM Analysis:

Modern project management software tools automate CPM calculations, providing a visual representation of the project schedule and helping identify activities with significant float.

1.6 Importance of Accurate Data:

Accurate estimates of activity durations, dependencies, and resource availability are crucial for precise finish float calculations. Overestimations can lead to wasted resources, while underestimations can create scheduling challenges.

1.7 Continuous Monitoring and Updating:

As the project progresses, it's essential to continuously monitor and update the CPM model to reflect actual progress and identify potential schedule changes.

Chapter 2: Models for Applying Finish Float in Oil & Gas Projects

This chapter explores different models and frameworks for effectively utilizing finish float in the context of oil and gas projects.
