CAC Construction Scheduling and Planning

Question 1

What does the Critical Path Method (CPM) identify in a project schedule?

Accepted Answer

The longest sequence of dependent activities that determines project duration

Answer

The most expensive sequence of activities in the project

Answer

The sequence of activities with the most available float

Answer

The activities that require the most labor resources

Question 2

In scheduling terminology, 'float' refers to:

Accepted Answer

The amount of time an activity can be delayed without delaying the project finish date

Answer

The cost reserve built into the project budget

Answer

The overlap between two concurrent activities

Answer

The lag time required between predecessor and successor activities

Question 3

A Gantt chart is primarily used to:

Accepted Answer

Display project activities against a time scale in bar chart format

Answer

Calculate the critical path of a project network

Answer

Determine resource leveling requirements

Answer

Estimate the total cost of a construction project

Question 4

Which scheduling technique is best suited for highly repetitive construction work such as highway paving or high-rise floor cycles?

Accepted Answer

Linear scheduling method (LSM)

Answer

Critical Path Method (CPM)

Answer

Program Evaluation and Review Technique (PERT)

Answer

Gantt chart scheduling

Question 5

A Finish-to-Start (FS) relationship between two activities means:

Accepted Answer

The successor cannot start until the predecessor finishes

Answer

Both activities must finish at the same time

Answer

The successor must start at the same time the predecessor starts

Answer

The predecessor cannot start until the successor finishes

Question 6

What is 'resource leveling' in construction scheduling?

Accepted Answer

Adjusting the schedule to smooth out peaks and valleys in resource demand

Answer

Allocating equal cost to each work activity

Answer

Assigning the same crew to all critical path activities

Answer

Leveling the grade of a construction site prior to building

Question 7

A Schedule Performance Index (SPI) of 0.85 indicates that a project is:

Accepted Answer

Behind schedule, completing only 85% of planned work

Answer

Ahead of schedule by 15%

Answer

On schedule with a 15% cost savings

Answer

Experiencing a 15% increase in resource costs
