Study set for CM 4101 Final Exam Review Questions and Answers 2024/2025 Construction Planning - CORRECT ANSWER-The process of determining how a project will be carried out. Planning answers questions: who? what? where?, and how? Construction Scheduling - CORRECT ANSWER-Process to determine when activities need to be started and completed. Answers the question: when? Project Control - CORRECT ANSWER-Is an active process to monitor and update the construction plan and the schedule. Monitoring: collect feedback about the progress of a project from various sources Updating: evaluate and forecast the actual progress of a project, then correct the target plan to economically meet the project's overall objectives. Bar Charts - CORRECT ANSWER-Simple and time-scaled presentations that show how major work activities are scheduled. Bar Charts (Time Scaled Network Model) - CORRECT ANSWER—The length of activity is represented by the length of the open bar. Stated in days. -The activity restraint is shown using a heavy vertical line with an arrow head. -The activity description is placed on the top of each bar. -The duration is in days. It is placed at the bottom left hand portion of each activity, or inside the bar. -The free float is shown as a horizontal dotted line between each activity. Gantt Chart/Bar Chart - CORRECT ANSWER--1917 Henry L. Gantt -During World War I, Henry L. Gantt developed a display for production control technique, later simplified as a scheduling technique called bar chart. CPM (Critical Path Method) - CORRECT ANSWER--1956 Morgan Walker -The complexities of construction work for chemical plants faced by Du Pont required more sophisticated planning and scheduling techniques -Network planning and mathematical theory that CPM is based upon -Computer technology PERT (Program Evaluation Research Task) - CORRECT ANSWER--1957 Booz, Allen & Hamilton -U.S. Navy Fleet Ballistic Missile Program -DR. Charles E. Clark developed a concept of network with three time estimates for each activity, and the logic and mathematics that form the basis of PERT Precedence Network - CORRECT ANSWER--1961 John Fondahl Bar Chart (A&D) - CORRECT ANSWER-Advantages: Simple and easy to use Disadvantages: -Project status cannot be determined. -Needs for schedule adjustments cannot be determined. -Activities for possible project acceleration cannot be determined. -Relies on extra links to show logical relationships between activities. Networks - CORRECT ANSWER--Networks are graphic representations using nodes and links. -Network Based Scheduling Techniques = Graphic Representation + Mathematical Theory Basic Network Concepts - CORRECT ANSWER—Activity: discrete part of a project that can be identified for planning, scheduling, monitoring, and controlling the construction project. -Event: an event is the point in time or an instant at which the status of completion of a project or an activity can be defined. -Duration: the duration of an activity is the period of time that will be consumed in completing a task. -Milestones: included in schedules to mark a particular point in time for reference or measurement. Milestones do not consume any time or resources. Arrow Diagrams and Precedence Diagrams - CORRECT ANSWER—Both use network presentations to represent activities, sequences/logic, times a
