OBJECTIVES OF SCHEDULING

Other Chapters

• Q1: Define Scheduling.
  Ans: A table showing the proposed duration of the construction of various items of work is known as schedule. The process of preparing such schedules is called scheduling.
• Q2: Define Bar Chart.
  Ans: The scheduled program of various activities is represented by a number of bars and hence the method of scheduling is known as “Bar Chart”.
• Q3: Define Critical Path Method (CPM).
  Ans: Critical Path Method (CPM) is a project management technique used to identify the longest sequence of dependent tasks in a project, which determines the shortest possible time to complete the project.
• Q4: Define Critical Path.
  Ans: It is the chain of tasks that must be completed on time; if any task on the critical path is delayed, the entire project will be delayed.
• Q5: Define Material Schedule.
  Ans: Moving & storing of materials in any form is known as “Material Schedule”. It is a schedule which shows the date of delivery of each type of material at site.
• Q6: Define Labor Schedule.
  Ans: Graphical representation of the labor requirement on certain days or during certain works is known as labor schedule.
• Q7: Define Equipment Schedule.
  Ans: It shows the type and quantities of equipment required on particular dates in the entire project. This enables the engineer to make proper arrangements.
• Q8: Write the importance of Scheduling.
  Ans: In Post-Tensioning, the prestressing force is applied to the steel tendons after the concrete is placed and cured.
• Q9: Define Float.
  Ans: It is the time by which activities can be delayed without delaying the total completion time of the project.
• Q10: Define Total Float.
  Ans: It is the difference between the LFT & EFT or the LST & EST. Mathematically:
  Total Float = L.F.T – E.F.T or Total Float = L.S.T – E.S.T
• Q11: Define Event.
  Ans: An event shows the completion of activity. It is indicated in the network by a number enclosed in a circle, square or triangle.
• Q12: Define Activity.
  Ans: The performance of a task or operation is known as activity, for example placing of steel bars etc.
• Q13: Define Critical Activity.
  Ans: Critical Activity is a task or activity in a project that lies on the critical path, meaning it must be completed on time to avoid delaying the entire project.
• Q14: Define Dummy Activity.
  Ans: It is an artificial activity shown by a dotted line in a network. It indicates that an activity following it, cannot be started before the completion of proceeding activity.
• Q15: Define Duration.
  Ans: The estimated time for the performance of an activity is known as duration. It is represented in days, weeks etc. It is denoted by D.
• Q16: Define Arrow and Circle in Critical Path Method.
  Ans: An arrow represents the sequence of activity on completion of which the whole project can be completed. A circle represents an Event.
• Q17: Define Network Diagram.
  Ans: It is the time by which activities can be delayed without delaying the total completion time of the project.
• Q18: Define E.S.T.
  Ans: The earliest start at which an activity can be started is called Earliest Start Time (E.S.T).
• Q19: Define E.F.T.
  Ans: The earliest time at which an activity can be finished is called Earliest Finish Time (E.F.T).
• Q20: Define L.S.
  Ans: L.S stands for Latest Start. It is the latest time at which an activity may be started without delaying the completion of the project.
  L.S = L.F – D
• Q21: Define L.F.T.
  Ans: L.F.T stands for Latest Finish Time. It is the latest time at which an activity can be finished without delaying the completion of the project.
  L.F.T = L.S + D
