Free Practice Questions for AACE International PSP Exam

Total float measures the flexibility in an activity’s timing within a schedule. It is defined as the amount of time an activity can be delayed without affecting the project’s overall completion date or the completion date of any of its successors.

Option A, B, and D accurately describe total float: it is calculated as the difference between early and late start/finish dates, can be positive or negative, and is associated with project completion​.

Option C describes free float, not total float, and thus is incorrect.

A logic loop occurs when a circular dependency is introduced, creating a scenario where activities cannot progress in a linear or logical manner.

Adding a relationship between F and I would create such a loop if existing dependencies between these or related activities already establish mutual dependencies.

 Hammock Activities (2001–2004):

Activity 2001 ("River Diversion Stage 1"): Duration = 92 days.

Activity 2002: Starts immediately after 2001, duration = 38 days.

Activity 2003: Starts immediately after 2002, duration = 15 days.

Activity 2004: Starts immediately after 2003, duration = 38 days.

 Calculate the Duration:

Total duration = 92 + 38 + 15 + 38 = 183 days.

 Cross-Verification with Answer Options:

Option A: Incorrect. Underestimates.

Option C: Incorrect. Overestimates.

Option D: Incorrect. Overestimates.

Option B: Correct. Matches the calculated duration.

 As-Planned vs. As-Built (APAB) Analysis:

A simple APAB compares the planned schedule to the actual schedule to identify deviations.

It does not involve inserting delaying events or re-forecasting the schedule, which makes it unsuitable for detailed analysis.

 Limitations of APAB:

Unsuitable for complex projects (A).

Inserting delays is not part of APAB (B).

Accuracy diminishes for long projects (C) or those requiring granular mid-project analyses (D).

 Conclusion: The correct answer is B, as inserting delays into the as-planned schedule is not a feature of simple APAB analysis.

 Activity 11001 Characteristics:

Activity 11001 (Spillway - Concrete) is logically defined as the final activity in the project.

Final activities in a project typically do not have successor activities since they signify project completion.

 Exclusion of Other Options:

Option A: Circular logic does not apply since the scheduling logic is linear and follows standard precedence diagramming methods.

Option B: Activity 11001 is not penultimate but the final activity.

Option C: The scheduler's error is highly unlikely in a controlled environment following PSP principles.

 Verification with PSP Guidelines:

The PSP Study Guide explains that final activities represent the culmination of a project's logical sequence and typically lack successors (Ref: PSP Study Guide, Chapter 2A: Logical Sequencing).

When planning a contractor's baseline critical path schedule for constructing a high-clearance bridge near an airport, a planner/scheduler must consider documents directly relevant to the project's execution and constraints. Here's the detailed reasoning:

Project Plans and Specifications (Option A):These documents contain the detailed design, materials, and methods necessary for construction. They are indispensable for planning the baseline critical path schedule.

Project Geotechnical Report (Option B):The geotechnical report provides critical information about soil conditions, foundational requirements, and potential challenges, which significantly influence construction sequencing and methods.

Regulations Published by the Government Aviation Agency (Option C):As the project is near an airport, these regulations will likely impose height restrictions, flight path considerations, and safety requirements. Compliance with these regulations is crucial to avoid project delays or legal issues.

Government's Report on Future High-Clearance Bridge Projects (Option D):This document provides information on future projects and does not pertain to the current construction project. It does not provide actionable data or constraints affecting the planning or execution of the baseline critical path schedule for the awarded project.

Conclusion: Option D is the least valuable document in this scenario as it does not contribute directly to the planning or scheduling of the current project.
