 Time-Scaled Logic Diagrams:

Represent activities with respect to a time scale (e.g., a calendar).

Show logical relationships and durations in a visually aligned manner, aiding in analysis and reporting.

 Common Misconceptions:

They are not the same as pure logic diagrams (B).

While often created using computer software, manual versions are also possible, so (A) is incorrect.

They are not specifically for calculating activity durations (C).

 PSP Study Guide References:

The guide identifies time-scaled logic diagrams as a tool for better visualization of schedules, where activities align with calendar dates​.

 Conclusion: The correct answer is D, as time-scaled logic diagrams are drawn to align activities with a calendar.

 SDOT, as the project owner or primary stakeholder, benefits most from a master schedule as it provides an overview of progress, resource allocation, and critical path analysis for the entire project.

 Contractors (e.g., BILCO) may rely on more detailed schedules specific to their scope rather than the overall master schedule.

 References: PSP Study Guide, Section 2.4.8 – Management Summary, which explains how master schedules are valuable to owners and stakeholders for overall project oversight.

 Critical Path Identification:

The critical path is the longest sequence of activities that determines the project’s minimum duration.

Path: A → B → G → H.

 Exclusion of Other Options:

Paths involving F, J, or non-critical activities do not align with the longest duration.

 Verification with PSP Guidelines:

The PSP Study Guide emphasizes identifying the critical path for schedule optimization (Ref: PSP Study Guide, Chapter 2A: Critical Path Analysis)

To determine how many activities in the "normal" schedule would be affected by the constraint of no activity exceeding a two-month duration (approximately 60 days):

Review the "Normal Schedule Days" Column:Look for activities with a duration greater than 60 days in the "Normal Schedule Days" column of the table provided in the image.

Count the Affected Activities:Count all activities where the "Normal Schedule Days" value exceeds 60.

Activities with durations greater than 60 days:

Activity ID 1000: 1072 days

Activity ID 1001: 85 days

Activity ID 2001: 92 days

Activity ID 3001: 152 days

Activity ID 4001: 152 days

Activity ID 5001: 102 days

Activity ID 6001: 140 days

Activity ID 6002: 115 days

Activity ID 6003: 152 days

Activity ID 9001: 175 days

Activity ID 9002: 180 days

Activity ID 9005: 72 days

Total Count:

There are 12 activities in the "normal" schedule exceeding the 60-day duration constraint.

Verified Answer:

A. 12.

Detailed Explanation with References: The constraint specifies that no activity should exceed a two-month (60-day) duration. By examining the "Normal Schedule Days" column, any activity with a duration greater than 60 days is non-compliant and therefore affected. The PSP study guide emphasizes reviewing contract requirements to ensure schedules adhere to such administrative constraints​.
