Discuss AACE International AACE-PSP Exam Topic 4 Question 49

Theoretically construct a summary activity for activities 6001 through 6003. Identify the governing predecessor and successor activities for the hammock:

APredecessor is activity 5001, successor is activity 8001

BPredecessor is activity 4001, successor is activity 8001

CPredecessor is activity 9001, successor is activity 9002

DPredecessor is activity 5001, successor is activity 8002

Suggested Answer: A

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

I feel like I’ve seen a similar question before, but I can’t recall if the successor is always the next activity in the sequence.

I think the predecessor should be activity 5001 since it seems to connect well with 6001 through 6003.

I remember we discussed hammock activities in class, but I'm not sure about the exact predecessor and successor for this one.
