Construction Scheduling 4101 Study
Guide Exam and Actual Answers.
Gantt Chart - Answer 1917, Developed by Henry L. Gnatt, display production control technique
simplified to bar chart
Critical Path Method (CPM) - Answer Developed by Morgan Walker in 1956. Made for Dupont
chemical plants, uses technology
PERT - Answer Program Evaluation Research Task, 1957, developed by the navy with three
time estimates for activities
Precedence Network - Answer 1961 John Fondahl
Why Planning, Scheduling and Control - Answer Complexity of construction projects, Control
resource consumption, Communicate the construction plan, Establish production goals, Monitor
and measure project progress, Manage changes
Construction Planning - Answer The process of determining how a project will be carried out
Construction Scheduling - Answer Process to determine when activities need to be started and
completed
Schedule - Answer time based arrangement of activities planned to take place in order to
efficiently complete a project, may also convey the logical relationships between activities
Project Control - Answer Project control is an active process to monitor and update the
construction plan and the schedule
Monitoring - Answer Collect feedback about the progress of a project from various sources
(feild operations, accounting, equip management, etc)
Updating - Answer Evaluate and forecast the actual progress of a project, then correct the
target plan to economically the projects overall objectives
, Bar Chart Advantages - Answer Simple and Easy to use
Bar Chart Disadvantages - Answer Project status cannot be determined, Needs for schedule
adjustments cannot be determined, Activities for possible project acceleration cannot be
determined, Uses extra links to show relationships between activities
Time Scaled Network Model (Activity Length) - Answer Represented by the length of the open
bar, Stated in days
Time Scaled Network Model (Activity Restraint) - Answer Shown using a heavy vertical line
with an arrow head
Time Scaled Network Model (Activity Description) - Answer Placed on the top of each bar
Time Scaled Network Model (Duration) - Answer In Days, placed at the bottom left hand
portion of each activity, or inside the bar
Free Float (Bar Chart) - Answer Shown as a horizontal dotted line between each activity
Networks - Answer Graphic representations using nodes and links
Network Based Scheduling Techniques - Answer Graphic Representation + Mathematical
Theory
Activity - Answer Discrete part of a project that can be identified for planning, scheduling,
monitoring, and controlling the construction project. Activities consume time, recources
(usually), have a start/finish, are assignable and measurable
Event - Answer An event is the point in time or an instant at which status of completion of a
project or an activity can be defined
Duration - Answer The duration of an activity is the period of time that will be consumed in
completing a task
