 Workweek Period Analysis:

Based on standard construction scheduling practices and project data, the workweek includes six days, with Sunday as a non-working day.

 Verification in Project Details:

The PSP Study Guide suggests that assumptions on workweeks must align with labor calendars and schedule configurations (Ref: PSP Study Guide, Chapter 2A: Calendars and Constraints).

 Proceeding without completing environmental studies introduces compliance risks, such as legal challenges or project shutdowns. This is not a feasible method for reducing the overall completion time as it contradicts environmental regulations and ethical standards.

 Methods like subcontracting (A) or reallocating resources (B) are feasible, as they leverage resource management.

 References: PSP Study Guide, Section 1.2.3 – Stakeholder Considerations, and Section 1.3.13 – Risk and Recovery Planning, which emphasize compliance with regulations and avoiding unmanageable risks.

To constrain a project's end date, a Finish-No-Later constraint is applied to the last activity. This ensures any slippage results in negative float, signaling delays relative to the fixed deadline.

Option A and B apply to earlier constraints, which are not relevant for controlling the project's end date.

Option D applies a constraint to the first activity, not the project finish.

This concept aligns with controlling project deadlines as described in the PSP Study Guide​.

 Understand Free Float:

Free float is the time an activity can be delayed without delaying the start of its immediate successor.

 Review Activity F in the Diagram:

Activity F has a successor that starts later, providing room for 2 months of free float.

 Cross-Verification:

Option A: Incorrect. Overestimates the float.

Option B: Incorrect. No float is incorrect for F.

Option C: Incorrect. 1 month is insufficient.

Option D: Correct. Matches the calculated free float for Activity F.

 If the duration of Activity B is reduced to zero, the completion of Activity C is determined solely by its own duration and predecessor relationships.

 Without knowing the explicit network logic, it is inferred that reducing Activity B to zero does not affect Activity C’s finish on Day 50, as its relationship with other activities remains intact.

 References: PSP Study Guide, Section 2.2.4 – Relationships and Calculations, highlights how relationships and durations impact completion dates.

 Activity 2002 in the Crashed Schedule:

Activity 2002 duration in the crashed schedule is 28 days.

Start Date: 12 August 2021.

Finish Date = Start Date + Duration (excluding non-working days).

 Calculation:

12 August + 28 days = 09 September 2021 (excluding weekends or non-working days based on typical calendars).

 Verification with PSP Guidelines:

Accurate calculation of start and finish dates aligns with scheduling best practices (Ref: PSP Study Guide, Chapter 2A: Schedule Development).

 Late Finish (LF) Transition Rule:

Late finish (LF) is calculated by adding one day to the early finish (EF) of the final activity.

EF of Activity 11001 is given, and the late finish is simply EF+1EF + 1EF+1.

 Cross-Verification with PSP Guidelines:

PSP methodologies state that late finish is derived from the forward pass using early finish logic, with specific adjustments based on activity relationships (Ref: PSP Study Guide, Chapter 2A: Forward and Backward Pass Calculations).

 Activity Relationships:

Activity 2002 is directly succeeded by Activity 2003 in the schedule.

The late start (LS) of Activity 2003 determines the late finish (LF) of Activity 2002, adjusted by any lags or additional constraints.

 Late Finish Calculation Formula:

LF of 2002 = LS of 2003 - 1 day.

This accounts for the predecessor-successor logic and the sequence of activities.

 Date Calculation:

Late start of 2003 = 10-06-01.

Late finish of 2002 = 10-06-01 - 1 day = 10-05-01.

 Verification:

PSP guidelines emphasize that late finish values are derived by subtracting any relevant time constraints from the successor's late start (Ref: PSP Study Guide, Chapter 2A: Backward Pass Calculations)
