Question 1

Is activity 7001 pictured correctly in the precedence diagram?

ANo, the total float is not shown correctly.

BYes, except the early finish date is not shown.

CNo, the start-to-start and finish-to-finish relationships are backwards.

DYes, the duration is 48 days.

Answer : D

Activity Details (7001 - 'Permanent Roads'):

Duration: 48 days in the Normal schedule.

Precedence Diagram Information: The schedule correctly reflects the logic and relationships as FS (Finish-to-Start) with successors.

Total Float and Dates Review:

No discrepancies are provided in the diagram.

Early Start (ES) and Early Finish (EF) align with the planned duration and dependencies.

Validation:

Total float is not specified as incorrect.

Early Finish dates, while not explicitly displayed, do not contradict the sequence.

Start-to-Start and Finish-to-Finish relationships are correctly oriented.

Conclusion: The activity is correctly represented with a duration of 48 days.

Question 2

Before the work begins, the contractor considers crashing the schedule. How much would the crashed general conditions have to be reduced to break even with the normal cost budget?

A$195 per day

BS1.772 per day

CGeneral conditions do not need to be reduced to break even

D$1.223 per day

Answer : B

Question 3

The project goals_________.

Aare the foundation for breakdown structures

Bare defined independent of any external stakeholder opinions

Cquantify performance and interface requirements

Dconsider all aspects of the project

Answer : C

Question 4

The primary determination of schedule detail is:

AThe frequency of update periods

BThe contract specifications

CThe staffing of planners and schedulers

DThe number of subcontractors working on a work package

Answer : B

Question 5

Each of the following accurately describes total float in a schedule EXCEPT:

AThe amount of time an activity can be delayed without delaying the overall project completion time.

BCan be positive or negative.

CThe amount of time an activity can be delayed without delaying the start or occurrence of any other activity or event in the network.

DComputed for an activity by subtracting its early finish from its late finish, or its early start from its late start.

Answer : C

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.

Question 6

In a "crashed" schedule, which is a chain of activities that precede activity 2004?

A1001, 2001, 2002, 2003

B2001, 2002, 2003, 2007

C1001, 2002, 2003

D1001, 2002, 2002, 2003, 3001

Answer : A

Crashed Schedule Predecessors to Activity 2004:

Activity 2004 (River Diversion to Pipeline) depends on completion of:

1001 (Preliminary Civil Work).

2001 (River Diversion Stage 1).

2002 (River Diversion Stage 2).

2003 (River Diversion Dam).

Exclusion of Other Activities:

Activity 2007 is not part of the crashed schedule's direct predecessor chain.

Other options include duplicated or incorrect entries.

PSP Study Guide Reference: Logical sequence analysis confirms these predecessors (Ref: PSP Study Guide, Chapter 2A: Activity Sequencing and Critical Path Analysis).

Question 7

Assuming conventional finish-to-start relationships, to calculate a schedule retaining the existing logic means that

AIt is calculated using the original logic.

BIt is calculated using logic reflecting out-of-sequence progress.

CAn out-of-sequence activity cannot resume until all predecessors are finished.

DThere is no such thing.

Answer : A

Retaining existing logic means preserving the original relationships and dependencies defined in the schedule. Even if progress is recorded out of sequence, calculations adhere to the pre-established logic unless explicitly changed.

Option B reflects adjustments for out-of-sequence progress but contradicts the original logic requirement.

Option C imposes restrictions that do not align with typical CPM calculations.

Option D is incorrect as the concept exists.

The PSP Study Guide discusses the importance of maintaining logic integrity in CPM scheduling.
