Question: 1

Determine the correct formula and date for the late finish for Activity 2001.

Exam Question 1 Exhibit 1

ALF.2001 - 1 day -> 08-28-01.

BLS.2002- 1 day-> 08-29-01.

CLS.2002 + 1 day -> 08-30-01.

DLS.2002 - 1 day -> 08-28-01.

Answer: B

Explanation:

Activity Details (2001 - 'River Diversion Stage 1'):

Successor: 2002 ('River Diversion Stage 2').

Relationship: Finish-to-Start (FS) with no lag.

Normal schedule duration for Activity 2001 = 92 days.

Backward Pass Calculation for Late Finish (LF):

The Late Finish (LF) of Activity 2001 is derived from the Late Start (LS) of its successor, Activity 2002.

Formula: LF.2001 = LS.2002 - 1 day.

Date Calculation:

Given: LS.2002 = 08-30-01 (as per data in the schedule).

LF.2001 = LS.2002 - 1 day = 08-30-01 - 1 day = 08-29-01.

Cross-Verification with Answer Options:

Option A: Incorrect. Misrepresents the Late Finish formula.

Option C: Incorrect. Adds 1 day instead of subtracting.

Option D: Incorrect. Incorrect date application.

Option B: Correct. Matches both formula and calculation.

Question: 2

Free float is the

ADifference between the early dates and late dates of an activity.

BAmount of time the early start of an activity can be delayed without impacting the early start of the successor activity.

CDifference between the early finish dates and late finish dates of an activity.

DDifference In float value of the critical path activities and the float value of the specific activity being analyzed.

Answer: B

Explanation:

Free float is a concept in Critical Path Method (CPM) scheduling that refers to the amount of time an activity's early start can be delayed without affecting the early start of any immediately succeeding activities.

Option A refers to total float, which considers early and late dates of an activity.

Option C also points to total float.

Option D does not define free float.

Free float is critical for project planners as it provides flexibility in scheduling without impacting downstream activities.

Question: 3

Midway through the project you received an executed change order for this project, adding thirty-three days to the contract for weather delays. In its simplest form, how would your next project update display the changed condition?

Exam Question 3 Exhibit 1

AAfter Activity 1000, add a new Activity 1050 with a start-to-start relationship to Activity 1000, and tie the end of this new activity with a finish-to-finish relationship to the final activity of the project.

BAfter Activity 1000, add a new Activity 1010 with a finish-to-start relationship to Activity 1000, and tie the end of this new activity with a finish-to-start relationship to the final activity of the project.

CAfter Activity 1001, add a new Activity 1011 with a finish-to-start relationship to Activity 1000, and tie the end of this new activity with a finish-to-start relationship to the final activity of the project.
Scenario Overview:
A change order has been approved, adding 33 days for weather delays. This requires updating the schedule to reflect the extended contract duration.
Impact on Scheduling:
The simplest and cleanest way to include the change is to create a new activity that represents the delay (e.g., Activity 1050).
The new activity is linked to Activity 1000 using a start-to-start (SS) relationship. This ensures the delay begins in parallel with the original contract start.
The finish-to-finish (FF) relationship with the final activity ensures that the extended duration impacts the project's overall timeline.
Cross-Verification with PSP Principles:
PSP principles emphasize the importance of maintaining logical integrity and clarity when updating schedules for change orders (Ref: PSP Study Guide, Chapter 2B: Schedule Maintenance/Controlling). This method ensures traceability of the delay without affecting activity logic unnecessarily.

Answer: A

Question: 4

Scenario: You are providing construction management services for a small office building project. Your duties include reviewing and approving the contractor's baseline schedule. The contractor has submitted the first baseline schedule for the project.

The contractor's baseline schedule submittal includes a bar chart, but no CPM diagram. Which of the following is the most significant shortcoming to using a bar chart to review the baseline?

AA bar chart cannot accurately reflect the impact of changes in durations or logic to the baseline

BA bar chart is always an oversimplified view of the project schedule

CA tor chart does not show all the activities required to construct the project

DA bar chart does not show whether the project with be completed within the allowable time

Answer: A

Question: 5

What does the narrow band at "Y" represent?

Exam Question 5 Exhibit 1

AResource limitation period.

BA rework period.

CActivity inactivity.

DYou cannot tell with the information supplied.

Answer: A

Explanation:

Interpret the Narrow Band at 'Y':

The narrow band at 'Y' is located on a part of the schedule where activities have been delayed or slowed down.

Such delays typically indicate resource limitations (e.g., insufficient manpower or equipment).

Reasoning:

No evidence of rework or activity inactivity is explicitly shown in the diagram.

Resource limitations are common in network diagrams to explain such periods.

Cross-Verification:

Option B: Incorrect. No evidence of rework exists.

Option C: Incorrect. Activity inactivity does not fit the context.

Option D: Incorrect. Sufficient information is provided.

Option A: Correct. Resource limitation fits the observed diagram behavior.
