
Simple & easy to read
Based on contractor field experience
Do not show interdependencies
Do not show critical path
 S-Curves
 Good for showing progress
 Do not show interdependencies
 Do not show critical path
 Line-of-Balance
 Show interdependencies
 May show progress
 Do not show critical path

CPM in Construction…
 MS Project is CPM & multi-format
 Excellent for small projects; easy to use
 Widely used & relatively inexpensive
 Several other products on market
 Primavera used for large projects



More flexible
Includes resource & budget
Includes database for tracking submittals
Requires more capable computers
Generally requires trained operator

Tasks are not all consecutive
Need to show interdependencies
Need to identify critical tasks & timing
Need to show slack or float
Need to see tasks superimposed
Need to chart progress & payment
5 Step Scheduling Process…
1.

5.
Identify key work elements
Estimate time durations for each
Establish logical order of tasks
Determine precedence/dependency
Display in graphical/network format
Activity = Basic work unit
 Any single, identifiable & measurable
work step in the total project.
 A “time consuming” task
 Two conventions:
 Activity on Arrow… AOA networks
 Precedence diagrams

Network relationships…
 Finish-to-start:


The activity may not begin until the preceding activity is completed
Most common or conventional relationship
Activity A
Activity B
Finish-to-start
Finish-to-start w/lag
 Start-to-start:


The activity may begin any time after the start of a preceding activity
Very common and useful, often includes a lag time
Start-to-start
Start-to-start w/lag
Network relationships…
 Finish-to-finish:


The activity must finish at the same time as a preceding activity
Infrequently used

Project Flow Chart
1. Identify activities = individual tasks
2. Arrange activities in logical order
3. Add a time line – from start to project completion
4. Array the tasks in “time order” sequence
5. Show “precedence”… what activity must be completed
before another can begin
6. Draw lines to connect activities to show flow of work
7. Time sequencing is “relative”… not exact
8. Flow chart is used to explain project tasks to team
