PSP Exam Dumps - AACE International Professional Level Certifications Questions and Answers

 Update Process Essentials:

Schedule updates track the current status of the project using actuals (start/finish dates), progress (percent complete), and future plans (remaining duration).

The original duration does not change and is part of baseline data, not required for routine updates.

 PSP Study Guide References:

Scheduling update procedures are discussed, emphasizing active progress tracking elements like actual start, percent complete, and remaining duration​.

 Conclusion: The correct answer is D, as original duration is not a variable considered in regular updates.

 Resource Leveling:

Resource leveling adjusts start and finish dates of activities to resolve resource conflicts or constraints, balancing availability and demand.

In construction projects, breaks in continuity of work for subcontractors can result in increased costs due to remobilization and demobilization.

 PSP Study Guide References:

The PSP guide explains that resource leveling must be carefully analyzed to avoid disruptions in work continuity​.

 Conclusion: The correct answer is A, as the scheduler must account for potential cost implications of resource leveling on subcontractors.

 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.

The Project Scope Statement typically includes:

Project objectives.

Justification.

Deliverables.

However, the contract between the contractor and owner is not included directly in the scope statement. Instead, it serves as a separate legal document governing the project's terms and conditions. This distinction is clear in project scope management practices discussed in the PSP materials​​.

 Definition of a Summary Activity (Hammock):

A summary activity, also referred to as a hammock activity, spans multiple detailed tasks and is governed by the earliest start (ES) of the first task and the latest finish (LF) of the last task.

 Activities 6001 through 6003 Overview:

6001: Starts after 5001 (Drill and Grout Dam Site).

6003: Ends before 8001 (Rock Fill to elevation 50).

 Identifying Predecessor and Successor:

Predecessor: Activity 5001 (Drill and Grout Dam Site).

Successor: Activity 8001 (Rock Fill to elevation 50).

 Cross-Verification:

Logical and temporal dependencies confirm that Activity 5001 must precede the hammock, and Activity 8001 must succeed it (Ref: PSP Study Guide, Chapter 2A: Logical Sequencing and Activity Relationships

The cumulative cost baseline typically forms an "S" curve, reflecting slow initial expenditures, accelerating progress during peak activities, and tapering off as the project concludes.

Option A, B, and D do not represent the characteristic shape of a project's cost curve.

The PSP Study Guide highlights the "S" curve as a standard graphical representation of cumulative project costs over time​.

To calculate the duration:

Total hours required: 240 hours.

Daily work hours per crew: 5 workers × 8 hours/day = 40 hours/day.

Duration = Total hours ÷ Daily work hours = 240 ÷ 40 = 6 days.

This calculation aligns with standard resource planning principles​.
