16. Scheduling
Construction scheduling is a graphical representation
which shows the phasing rate of construction
activities with the starting completion dates and
sequential relationship among the various activities or
operations in project so that work can be carried out
in an orderly and effective manner.
April 18, 2013 Construction Management 16
Agrawal
17. Preparation of scheduling
1. The project is divided into number of operation and the
sequences of these operation can be derived after knowing
their relationship properly.
2. The quantity of work involved in each operation has to be
calculated.
3. The time required for completion of the project as well as
different activities are to be calculated. This can be done
from the quantity of work involved and rate of performing
each work.
April 18, 2013 Construction Management 17
Agrawal
18. Uses of scheduling Advantages of scheduling
1. Gives quantity of work 1. Many alternative method can
involved, labour, be choose
materials and equipment 2. Clear idea regarding workers,
at each stage. materials, equipments
2. Actual progress of work 3. Staring time of work is
can be check known
3. Carried out in systematic 4. Resources utilization is
manner minimum

the final achievement of the project objectives.
April 18, 2013 Construction Management 21
Agrawal
22. Terms in Network Diagram
1. Activity : any position of project which consume time ot
resources and has a definite beginning and an end called as
an activity. It is denoted by an arrow
2. Event : the beginning or completion of an activity is termed
as an event. It indicates a particular instant of time at which
some specific milestone has been achieved.
3. Network logic : this denotes the technical dependencies
among activities. A good network logic reflects cost
effectiveness of project in long run.
4. Dummy : it similar to an activity but it does not consume
any resources. It represent by Dashed Arrow

25. Types of NETWORKS
1. Activity on Arrow (A-O-A) or Arrow Diagram : the arrow
represent activities and node represent the events.
2. Activity on Node (A-O-N) or Precedence Diagram : the
node represent activities and arrow represent the events.
3. Event oriented networks (PERT type)
April 18, 2013 Construction Management 25
Agrawal
26. Rules for drawing a Networks
1. Network will have only one initial node. Initial node will be only out going
arrows
2. Network can have only one final node. Final node will have only one incoming
arrow
3. No activity can start until its tail event has occurred
4. An event can’t occur until all the activities leading upto it are completed
5. No event can occur twice. Hence network looping isn’t permitted
6. An arrow should represent singular situation. Individuality and separate entity
of each activity should be maintained.
7. The network should be drafted such that all activities are completed to reach
end objectives
8. All constraints and interdependencies should be shown properly on the network
using dummies
9. Network logic should always be maintained
10. Time flow is usually shown from left to right.
April 18, 2013 Construction Management 26
Agrawal
27. Fulkerson’s Rule for Numbering the Events
1. There will be single initial event in network which has only
arrows coming out of it. This event is given number 1.
2. All arrows coming out of event 1 are neglected. This
provides us with one or more initial events. These event are
numbered 2,3,4,5 etc.
3. Again neglect all the arrows coming out of these numbered
events. A few more initial events will be created. These are
also numbered similarly.
4. This operation is continued until last event is reached and
numbered.

28. CPM Critical Path Method
1. CPM was discovered jointly by DuPont and Reunington
Rand Univac in 1957
April 18, 2013 Construction Management 28
Agrawal
29. Difference between CPM & PERT
• CPM is activity oriented • PERT is event oriented
• Time estimates are of fair degree • Time estimates are not that
of accuracy accurate
• Deterministic approach • Probabilistic approach
• Cost is governing factor • Time is governing factor
• Project duration is fixed and cost • Cost is directly proportional to
is minimum time
• Critical path which joins critical • Her critical path is path which
activities joins the critical events
April 18, 2013 Construction Management 29
Agrawal
30. CPM
• Earliest Event Time : earliest occurrence time is the earliest time
at which an event can occur.
TEj = TEi + tij
where TEj = earliest event time of head event
TEi = earliest event time of tail event
tij = duration of the activity (i-j)
• Latest Event Time : latest allowable occurrence time is the latest
time by which an event must occur to keep project on schedule.
TL = TLi - tij
where TL = latest event time of head event
TLi = earliest event time of tail event
tij = duration of the activity (i-j)
April 18, 2013 Construction Management 30
Agrawal
31. CPM Activity Time
• Earliest start time : is earliest time by which an activity can start.
– EST =TE(i)
• Earliest finish time : is earliest time by which an activity can completed.
– EFT = EST = tij
• Latest start time : time at which an activity can start without delaying
completion of project as whole.
– LST = LFT - tij
• Latest finish time : time at which an activity can finish without delaying
completion of project as whole.
– LFT = TL(i)
April 18, 2013 Construction Management 31
Agrawal
32. Float
• Float denote the flexibility range within which activity start and
finish times many fluctuate without affecting total project
duration
• Total Float : it is time span by which starting or finishing of an activity
can delayed without affecting overall completion time of project.
– FT = LFT – EFT
• Free Float : it is that duration by which an activity can be delayed
without delaying any other succeeding activity.
– FF = FT - Sj
• Independent Float : it is excess time available if the preceding activity
ends as late as possible and the succeeding activity starts as early as
possible.
– FID = FF - Si
• Interfering Float : it is that difference between total float and free
float.
– FIT = FT – FF = Si
April 18, 2013 Construction Management 32
Agrawal
33. Classification of Activities
1. Sub critical activities : when float is +ve; the activity
needs normal attention but has no flexibility.
2. Critical activities : when float is zero; the activity needs
extra attention. This has no freedom of action.
3. Super critical activities : when float is –ve; such
activities require very special attention and care.
April 18, 2013 Construction Management 33
Agrawal
34. PERT
• Program Evaluation and Review Technique is management tool
used for planning, controlling and reviewing a project.
• It follows probabilistic approach towards time durations.
• It is also event oriented network method where more importance is
given to the achievement of discernible milestone rather than the
activity can’t be made.
• Slack can be positive, zero or negative
• Positive Slack = it is obtained when TL is more than TE. It
indicates on schedule condition
• Zero Slack = it TL is equal to TE. It indicate on schedule condition
• Negative Slack = it TL is less than TE. It indicates behind the
schedule

Construction Industry
• Date : it can be defined as group of non-random symbols which represent
things that have happened. Data of facts that are obtained by observation or
research and which are recorded frequently are called as Raw data or Basic
data
