Your project schedule shows that the concrete pour activity can start on day 15 (Early Start) but doesn't need to start until day 18 (Late Start) without delaying the project. What is this activity's total float?
Correct Answer
C) 3 days
Total float equals Late Start minus Early Start. In this case, 18 - 15 = 3 days of total float.
Why This Is the Correct Answer
Total float represents the amount of time an activity can be delayed without affecting the project completion date. It is calculated by subtracting the Early Start from the Late Start (or Early Finish from Late Finish). In this case, the concrete pour can start as early as day 15 but can be delayed until day 18 without impacting the project, giving it 3 days of total float. This flexibility allows project managers to optimize resource allocation and scheduling.
Why the Other Options Are Wrong
Option B: 15 days
This answer confuses the Early Start date (15) with the total float calculation. The Early Start is when the activity can begin, not the amount of scheduling flexibility available.
Option D: 2 days
This answer incorrectly assumes a different calculation or misreads the given dates. The difference between day 18 and day 15 is 3 days, not 2 days.
Memory Technique
Remember 'LSES' - Late Start minus Early Start equals total float. Think of it as 'how much LATER can I start?' - that's your float time.
Reference Hint
Look up 'Critical Path Method (CPM)' and 'Float Calculations' in project management or scheduling chapters of construction management references.
