### Construction Scheduling Week 2 Quiz Answers

#### Quiz 1: Critical Path Method

Q1. In construction industry, any project:

- It can have no critical path.
**It must have at least one critical path.**- It may have or have not critical path depends on its nature.

Q2. If we want to save time and work on decrease the total duration of a project, we can do the following:

- Invest more resources on any activity either critical or noncritical.
- Ask our labors to come and work overtime.
**Focus your resources only on the critical activities.**

Q3. If we have 2 construction activities that has conflict of resources; which activity you will give a priority to perform from the below three options:

**The critical activity.**- The longer activity in duration.
- The activity that has more budget.

Q4. From the activity on node diagram in this example (without performing any forward and backward pass calculations) what is the total duration of the project?

- 12
**15**- 18

Q5. How many critical paths are in this project?

- 1
- 2
**3**

Q6. When it comes to the critical activities in a construction project:

- All critical activities may belong to a critical path.
**A delay in any critical activity will extend the project duration**- All critical activities can be delayed at least 1 day without lengthening the project duration.

Q7. Given the following activities and their durations, determine the duration of the project:

Activity A – duration = 4 days

Activity B – duration = 7 days

Activity C – duration = 2 days

Activity D – duration = 3 days

Activity E – duration = 5 days

**Start –> Activity A –> Activity B –> Activity C –> Finish**

The duration of the project would be:

- 12 days
- 13 days
- 10 days
**15 days**

Q8. What is the duration of the path; A, B, E and G?

**20 days**- 18 days
- 16 days
- 14 days

**Q9. SELECT ALL paths in the project below:**

**ABEHI****ABEFHI****ABFHI****ACDGI**- ACFHI
- ACGI
**ADGI**

**Q10. Calculate the critical path in the following diagram:**

- 9
- 15
**17**- 19
- 21

Q1. If you are at a construction project and an engineer mentioned that: “This activity has a float of 3 days”. When the engineer did not specify the type of the float, usually the commonly referred to is:

**Total Float**- Free Float
- Independent Float

Q2. What is the total float of any critical activity?

- One Day.
- Zero
**It depends if the critical activity is on a critical path or not.**

Q3. What will happen if an activity got delayed from its early start by more than its total float?

- Nothing will be affected.
**Only the activity that follows will be delayed.**- The entire project duration will be delayed.

Q4. Finish the following statement: “The total float is the amount of time that an activity can be delayed from its early start date without delaying the ________ finish date. Free float is the amount of time that an activity can be delayed without delaying the early start date of any ___________ activity”.

**Successor , Project.**- Project, Successor.
- Predecessor, Project.
- Project, Predecessor.

Q5. From the diagram in this example, calculate the following:

The free float of activity D:

**3**- 4
- 5
- 6

Q6. From the diagram in this example, calculate the following:

The free float of activity B:

- 0
- 1
**2**

Q7. From the diagram in this example, calculate the following:

The total float of activity C:

- 3
**5**- 8

Q8. From the diagram in this example, calculate the following:

The free float of activity C:

**3**- 5
- 8

Q9. Suppose this project starts on Feb. 1st, 2017 on a calendar that has Saturday and Sunday as weekend days.

When is the project expected end-date?

- Feb. 17th, 2017
**Feb. 22th, 2017**- Feb. 16th, 2017
