BCM Construction Scheduling and Planning 2

Question 1

The Program Evaluation and Review Technique (PERT) differs from CPM primarily because PERT:

Accepted Answer

Uses three time estimates to account for schedule uncertainty

Answer

Does not use a network diagram

Answer

Only works for repetitive construction tasks

Answer

Requires resource loading for every activity

Question 2

In PERT analysis, the expected duration (te) of an activity is calculated using the formula:

Accepted Answer

te = (O + 4M + P) / 6

Answer

te = (O + M + P) / 3

Answer

te = (O + 2M + P) / 4

Answer

te = (M + P) / 2

Question 3

Which scheduling technique is best suited for highly repetitive construction operations such as high-rise building construction?

Accepted Answer

Line of Balance (LOB)

Answer

CPM

Answer

PERT

Answer

Gantt Chart

Question 4

Schedule compression through 'Crashing' involves:

Accepted Answer

Adding resources to critical path activities to shorten their duration at additional cost

Answer

Removing non-critical activities from the schedule

Answer

Performing activities in parallel that were originally sequential

Answer

Reducing project scope to meet deadlines

Question 5

Fast-tracking as a schedule compression technique involves:

Accepted Answer

Overlapping phases or activities that were originally planned in sequence

Answer

Hiring faster subcontractors

Answer

Adding more workers to critical activities

Answer

Using prefabricated materials to reduce installation time

Question 6

A contractor is updating a construction schedule and notices the project has a negative float. This means the project is:

Accepted Answer

Behind schedule and the planned completion date cannot be met

Answer

Ahead of schedule

Answer

On schedule

Answer

Using too many resources

Question 7

What is a 'Look-Ahead Schedule' commonly used for in construction project management?

Accepted Answer

A 3-to-6-week short-term schedule used to coordinate upcoming work and identify constraints

Answer

Long-range 5-year planning for a construction firm

Answer

The baseline schedule submitted at project start

Answer

A schedule used exclusively for procurement of long-lead materials
