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

 Calculation of Total Lifts Required:

3 column pours = 28×3=8428 \times 3 = 8428×3=84.

Additional lifts = 150150150.

Total lifts = 84+150=23484 + 150 = 23484+150=234.

 Lifts Per Day with One Crane:

1 crane performs 30 lifts per day.

 Required Duration:

Minimum planned working duration = ⌈234÷30⌉=18\lceil 234 \div 30 \rceil = 18⌈234÷30⌉=18.

 Verification with PSP Guidelines:

Aligning workload with equipment capacity ensures practical schedule planning (Ref: PSP Study Guide, Chapter 2B: Workload Balancing).

 Scenario Review:

Delay in the parking structure foundation is an off-critical path activity.

No impact on the overall project completion date.

 Delay Analysis:

While the foundation activity is delayed, the float ensures that no downstream activities are impacted.

 Cross-Verification:

Option B: Incorrect. Assumes a 4-day impact.

Option C: Incorrect. Overestimates delays.

Option D: Incorrect. Miscalculates delays.

 Logic Organization Requirement:

Activity 6002 is required to begin 10 days after the start of Activity 6001.

A start-to-start (SS) relationship with a 10-day lag effectively captures this requirement.

 Exclusion of Other Options:

Option B: Placing the lag on Activity 6002 introduces unnecessary complexity.

Option C: Start-to-finish relationships are not appropriate for this situation.

Option D: A finish-to-start relationship does not meet the requirement of aligning start times.

 Verification with PSP Guidelines:

The PSP Study Guide emphasizes using SS relationships with lags for activities that need staggered starts (Ref: PSP Study Guide, Chapter 2A: Relationships and Lags).

 Delay Analysis:

Analyzing delays contemporaneously ensures accurate understanding of their causes and effects, helping stakeholders mitigate impacts in real time.

Waiting until after the project introduces risks of incomplete or inaccurate records.

 PSP Study Guide References:

Contemporary delay analysis is highlighted as a best practice for effective delay resolution and management​.

 Conclusion: The correct answer is B, as contemporaneous analysis is the most effective way to address project delays.

Driving Activity Concept:

The driving activity in a backward pass is the one that determines the late start or finish of the dependent activity.

Activity 10001 (Valve House - Complete) is directly dependent on its successor, Activity 11001 (Spillway - Concrete).

Backward Pass Logic:

In backward pass calculations, the late start of Activity 11001 establishes the late finish of Activity 10001 due to their finish-to-start (FS) relationship.

This makes Activity 11001 the driving activity.

Verification:

According to the PSP Study Guide, driving activities are identified based on their logical ties and the critical path's constraints (Ref: PSP Study Guide, Chapter 2A: Activity Relationships and Critical Path Analysis).

Thus, the driving activity for Activity 10001 is A. Activity 11001.

To calculate the completion day for Activity C:

Reduce Activity A's duration by five days.

Recalculate dependent activities' start and finish times using forward pass logic (PSP Study Guide, Subchapter 2.2.4, "Relationships").

Sum up the adjusted durations to determine the completion day for Activity C.

This aligns with the logic of schedule adjustments and dependencies as outlined in the PSP Study Guide.

 Granting Time Extensions:

Differing site conditions are excusable delays under standard contract terms, requiring time extensions.

Centrifuge delays and shop drawings typically fall under the contractor's responsibility and are not excusable.

 Excluded Options:

A & B: Shop drawing-related delays are the contractor's risk unless explicitly agreed otherwise.

D: Combining excusable and non-excusable delays does not entitle an extension.

 Verification with PSP Guidelines:

Granting time extensions aligns with contractual principles outlined in PSP-related contracts (Ref: PSP Study Guide, Chapter 1C: Delay Analysis and Claims).
