PERT Pretest

Graph or bar chart with a bar for each project activity that shows  passage of time which provides visual display of project schedule

• PERT/CPM

• GANTT CHART

• PRIMAVERA

• BAR SCHEDULE

Indicates only precedence relationships and does not require any time of effort

• Dummy

• Slacks

• Float

• Event

Latest time an activity can be completed without delaying critical path time

• Early Start

• Early Finish

• Late Start

• Late Finish

It refers to the amount of extra time that exists for an activity when all activities preceding it start at their Early Start (ES) date.

• Float

• Slacks

• Total Float

• Free Float

The longest path (time) in a network diagram and it determines the project duration.

• Critical Activities

• Critical Path

• Activity on Node

• Activity on Arrow

A perimeter fence required 11,200 units of 6” CHB to complete. If a mason has an average daily installation productivity of 320 units, what is its estimated duration for a crew of 5 mason/day

• 6 days

• 7 days

• 3 days

• 4 days

Draw the Network diagram given the ff:

A, B and C are starting activities and may begin at the same time.

 D and E follows A and E is an ending activity

 G follows and depends on C.

 F is dependent on the completion of B and D.

 G and F must be done before H, an ending activity, can start.

What is the Critical Path?

A=5, B=4, C=5, D=3, E=8, F=2, G=6 and H = 5 (all in days)

• A-E

• A-D-F-H

• B-F=H

• C-G-H

From the Network Diagram Shown,

What is the project duration?

• 16 days

• 15 days

• 14 days

• 13 days

From the same Network Diagram

What is the duration of the shortest path?

• 13 days

• 14 days

• 15 days

• 16 days

From the same Network Diagram

What is the late start of Activity B but still

project can still be completed on its target duration?

• 6 days

• 5 days

• 9 days

• 7 days
