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
