Construction Scheduling Common methods: 1.Bar Charts 2.Velocity Charts 3.Line-of-Balance Charts 4.Network Diagrams: CPM/PERT Characteristics of methods Bar Charts 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 Bar Chart Schedule Velocity Chartor S-curve Line-of-Balance Chart CPM/PERT Chart Double Click 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 CPM in Construction 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.Identify key work elements 2.Estimate time durations for each 3.Establish logical order of tasks 4.Determine precedence/dependency 5.Display in graphical/network format Activity = Basic work unit Any single, identifiable & measurable work step in the total project.
