Town planning
• Town planning means planned & controlled growth of
town by dividing town in to different land use zones and
regulating building construction to provide better
environment for the people of the town.
• In the town planning areas of town are divided into
residential, commercial, recreational and industrial
zones, which is called zoning.
• Floor space index, and other byelaws are fixed to guide
and regulate the building construction.
• For towns and cities master plan for town planning
schemes are prepared to accommodate future growth of
town in better way. Planning of very large area covering
several towns and villages is known as regional planning.
Town Planning
Functions of Civil Engineering
• Civil engineering functions performed can
broadly be classified in three categories.
• Before construction
• During construction
• After Construction
Before Construction
• Feasibility study
• Surveying
• Site investigation
• Planning
• Design and drawing
• Estimating
• Planning & Scheduling
Before Construction
• In the beginning technical feasibility, environmental
impact assessment and economical viability of the
project are studied. Surveying includes preparing site
plan, contour map and measurement of field dimensions
and levels.
• Soil investigation includes collecting data regarding soil
and bearing capacity of soil. Soil investigations is done
for the purpose of foundation design.
• On the basis of the data collected planning, designing, are
carried out and drawings are prepared. Estimates are
prepared to know the probable cost of completion of work
and detailed planning and scheduling are prepared to carry
out different activities in time without any delay.
During Construction
• Dealing with clients, Consulting engineer
and contractors
• Execution and supervision
• Quality control
• Costing
During Construction
• Owner, engineer and contractor are the three
constituents of a construction team in engineering
profession, hence continuous liaison among
themselves is a very essential for the speedy progress
of the work.
• Execution of work is actual construction carried out
on the site with materials and equipment's, by the
skilled and unskilled work force, under the technical
guidance and supervision of engineer in charge.
During the construction engineer has to supervise the
work carried out as per the specifications for quality
control. Costing is the accounts procedure of arriving at
the actual cost of construction.
After Construction
• Maintenance and repairs
• Valuation
• After the construction regular maintenance of
structures is to be carried out. Valuation is
carried out for the purpose of sale, purchase
and many others purposes.

Impact of Infrastructure Development on the
Economic Development of a country
• The infrastructural facilities mainly transportation, power,
communication, water resources, banking, science and technology create
environment in which Industries and business can grow. Due to the basic
facilities which any industry needs are provided by infrastructural sector,
country has progressed well. Per capita income and Gross domestic
product are the economic measures for assessment of development.
• Per Capita Income:
• Per Capita income is the average income of normal resident of a country
in a particular year. It is obtained by dividing national income of a
country by its population
• Gross domestic Product:
• Gross domestic product at market price is the value of all fixed goods
and services at prices prevailing in the market produced in the domestic
territory of a country during a given year.
• Due to the acceleration of progress of infrastructural projects overall
development and upliftment of common man can be done. Thus the
infracture development is key to economic development of any country.
Infrastructure Development
Importance of Planning, Scheduling, and
Construction Management.
Management
• Management is a social and scientific process of defining
the objectives, planning, organizing, coordinating,
motivating, controlling and harnessing the resources of an
organization at the optimum level to achieve
predetermined goal.
• Management is concerned with When? Who? Why? Where ?
And How?
• Five M of management Man, Money, Material, Machine, and
Methods.
• The functions of management are planning, organizing,
staffing, directing, coordinating, controlling and
communicating.
Importance of Construction
Management
• It gives guidelines regarding the execution of construction
work to be carried out.
• It helps in preparing construction schedule. Schedule is a
systematic path of different activities carried out one after
another. It helps in defining goals and planning procedure.
• It helps in proper management of material, labour and
equipments.
• It helps in arranging for finance and due to proper
construction management there is financial and overall
control on the work.
• Due to proper construction management project can be
completed in estimated completion cost and completion time.
Construction Management
Functions of the construction
Management
• Project is divided into different phases.
• Planning and preparing construction schedule.
• Estimating requirements of material & labour.
• Procurement of material plant, machinery and
employing labours.
• Arranging for finance and payment of material and
salaries of labours.
• To establish communication between various sections.
• To have overall control which includes financial control
of the project and to maintain quality and
workmanship.
Importance of Planning
• Planning is the management process which transforms goals or
policies into a method of reaching the objectives. Planning is setting
up of order to complete the project.
• The following aspects are to be considered in planning of a
construction project.
• Selection of proper site, topography, soil and cost of land.
• Surveying, designing, drafting and estimation are basic planning
exercise for civil works.
• To estimate cost of completion and time of completion of work.
• Planning source of finance for the project.
• Planning of resources includes calculating man power needs,
requirements of skilled and unskilled labours. To plan the purchase of
materials by finding out when and what quality of material are to be
purchased. To arrange for the equipment's either to be purchased or
hired.
• Establish stores for material and workshop for machinery.
Construction Planning
Scheduling
• For the planning of future course of action of the project,
entire project is divided into different activities of work. Say
for example, in building work excavation, laying base
concrete in foundation, masonry work in substructures etc.
are different activities.
• Now each activity has some time required for its completion
that is known as its duration. For civil engineering
planning, most common period for duration considered is in
the days or weeks.
• Scheduling is carried out to arrange the proper sequence of
different activities to be carried out for the project considering
dependence and duration of different activities.
• Scheduling gives direction regarding order in which different
activities can be started, it also gives details of completion time
required for the project. Scheduling gives us detail regarding
the most optimum time of start and completion of project.
Scheduling
Importance of scheduling
• Scheduling is very important looking to its following
advantages:
• Well defined order of the execution of different activities
can be known. Thus empowering decision making process
and gives clear guide line for progress of work.
• Labour requirement at different time period is known, hence
phased purchase of material can be made, which reduces the
problem of storing the material on the site and hence reduces
problem of material handling on site.
• Material requirement at different time period is known,
hence phased purchase of material can be made.
• Proper time of hiring or purchasing of the equipment and
machinery can be known.
Importance of scheduling
• Proper control over finance can be made. Well before the
need, arrangement for the funds can be made.
• It also helps in controlling the expenditure.
Scheduling Techniques
• The common techniques for scheduling any project
are mentioned as below:
• Bar Chart
• Critical Path Method (CPM)
• Project Evaluation & Review Technique.(PERT)
Bar Chart
• Bar char is a graphical representation of different
activities. Each activity is represented by a thick
line known as bar. Time is mentioned on X-axis
and activities on Y-axis.
• Bar spreads horizontally across the duration.
Beginning and end of activity is clearly represented
by beginning and end of a bar. The part of activity
which is completed is shown by a dark shade on the
bar.
Bar Chart
Advantages of Bar Chart
• It is very simple method and easy to understand
• Change in the bar char is easy to understand
• Progress can be known at any stage.
• Modification in the chart is easy.
Limitation of Bar Chart
• It is useful for small and simple jobs
• Interdependency of activities is not well defined.
• It does not suggest priorities of work.
• Uncertainties are not considered.
Network Techniques
• In this method entire project planning is done with
the help of network drawing
• Critical Path Method ( CPM)
• Project Evaluation and review Technique ( PERT)
Critical Path Method ( CPM)
• Critical path method is widely used method for
planning big projects involving many
interdependent activities and having
complicated interrelationship. It ha become
very useful tool for engineers working in
construction management.
• In Critical path method work is divided into
activities. The beginning and end of the activity
is known as event.
• In critical path method, network diagram is drawn
showing an arrow for activity and circle for event.
Critical Path Method ( CPM)
Advantages of Critical Path Method
• It is useful for big projects having more
interrelated activities.
• As critical activities are known, it provides
guidance regarding where more attention is
required.
• It improves overall control and monitoring.
• It helps in proper labour and material
management.
• As delay is reduced, it results in saving the cost.
Limitations of Critical Path
• It does not consider uncertainties in planning.
• CPM is not useful for research and development
type of project.
Critical Path Method ( CPM)
Project Evaluation and review Technique
( PERT)
• PERT Technique considers the uncertainties of the
project.
• Optimistic time, most likely time, and pessimistic
time are the three time estimates used in the PERT.
Optimistic time ( to) is the time when all situations are
favorable. Most likely time (tm) is the time normally
taken for the completion of the activity.
• The pessimistic time (tp) is the time when maximum
time is taken for the activity to complete due to most
unfavorable situation. The expected time is the
weighted average of all the above mentioned three
time.
Project Evaluation and review
Technique ( PERT)

Per capita income and Gross domestic product are the economic measures for assessment of development. • Per Capita Income: • Per Capita income is the average income of normal resident of a country in a particular year. It is obtained by dividing national income of a country by its population • Gross domestic Product: • Gross domestic product at market price is the value of all fixed goods and services at prices prevailing in the market produced in the domestic territory of a country during a given year. • Due to the acceleration of progress of infrastructural projects overall development and upliftment of common man can be done. Thus the infracture development is key to economic development of any country.
  • 40. Importance of Planning, Scheduling, and Construction Management. Management • Management is a social and scientific process of defining the objectives, planning, organizing, coordinating, motivating, controlling and harnessing the resources of an organization at the optimum level to achieve predetermined goal. • Management is concerned with When? Who? Why? Where ? And How? • Five M of management Man, Money, Material, Machine, and Methods. • The functions of management are planning, organizing, staffing, directing, coordinating, controlling and communicating.
  • 41. Importance of Construction Management • It gives guidelines regarding the execution of construction work to be carried out. • It helps in preparing construction schedule. Schedule is a systematic path of different activities carried out one after another. It helps in defining goals and planning procedure. • It helps in proper management of material, labour and equipments. • It helps in arranging for finance and due to proper construction management there is financial and overall control on the work. • Due to proper construction management project can be completed in estimated completion cost and completion time.
  • 43. Functions of the construction Management • Project is divided into different phases. • Planning and preparing construction schedule. • Estimating requirements of material & labour. • Procurement of material plant, machinery and employing labours. • Arranging for finance and payment of material and salaries of labours. • To establish communication between various sections. • To have overall control which includes financial control of the project and to maintain quality and workmanship.
  • 44. Importance of Planning • Planning is the management process which transforms goals or policies into a method of reaching the objectives. Planning is setting up of order to complete the project. • The following aspects are to be considered in planning of a construction project. • Selection of proper site, topography, soil and cost of land. • Surveying, designing, drafting and estimation are basic planning exercise for civil works. • To estimate cost of completion and time of completion of work. • Planning source of finance for the project. • Planning of resources includes calculating man power needs, requirements of skilled and unskilled labours. To plan the purchase of materials by finding out when and what quality of material are to be purchased. To arrange for the equipment's either to be purchased or hired. • Establish stores for material and workshop for machinery.
  • 46. Scheduling • For the planning of future course of action of the project, entire project is divided into different activities of work. Say for example, in building work excavation, laying base concrete in foundation, masonry work in substructures etc. are different activities. • Now each activity has some time required for its completion that is known as its duration. For civil engineering planning, most common period for duration considered is in the days or weeks. • Scheduling is carried out to arrange the proper sequence of different activities to be carried out for the project considering dependence and duration of different activities. • Scheduling gives direction regarding order in which different activities can be started, it also gives details of completion time required for the project. Scheduling gives us detail regarding the most optimum time of start and completion of project.
  • 48. Importance of scheduling • Scheduling is very important looking to its following advantages: • Well defined order of the execution of different activities can be known. Thus empowering decision making process and gives clear guide line for progress of work. • Labour requirement at different time period is known, hence phased purchase of material can be made, which reduces the problem of storing the material on the site and hence reduces problem of material handling on site. • Material requirement at different time period is known, hence phased purchase of material can be made. • Proper time of hiring or purchasing of the equipment and machinery can be known.
  • 49. Importance of scheduling • Proper control over finance can be made. Well before the need, arrangement for the funds can be made. • It also helps in controlling the expenditure.
  • 50. Scheduling Techniques • The common techniques for scheduling any project are mentioned as below: • Bar Chart • Critical Path Method (CPM) • Project Evaluation & Review Technique.(PERT)
  • 51. Bar Chart • Bar char is a graphical representation of different activities. Each activity is represented by a thick line known as bar. Time is mentioned on X-axis and activities on Y-axis. • Bar spreads horizontally across the duration. Beginning and end of activity is clearly represented by beginning and end of a bar. The part of activity which is completed is shown by a dark shade on the bar.
  • 53. Advantages of Bar Chart • It is very simple method and easy to understand • Change in the bar char is easy to understand • Progress can be known at any stage. • Modification in the chart is easy.
  • 54. Limitation of Bar Chart • It is useful for small and simple jobs • Interdependency of activities is not well defined. • It does not suggest priorities of work. • Uncertainties are not considered.
  • 55. Network Techniques • In this method entire project planning is done with the help of network drawing • Critical Path Method ( CPM) • Project Evaluation and review Technique ( PERT)
  • 56. Critical Path Method ( CPM) • Critical path method is widely used method for planning big projects involving many interdependent activities and having complicated interrelationship. It ha become very useful tool for engineers working in construction management. • In Critical path method work is divided into activities. The beginning and end of the activity is known as event. • In critical path method, network diagram is drawn showing an arrow for activity and circle for event.
  • 58. Advantages of Critical Path Method • It is useful for big projects having more interrelated activities. • As critical activities are known, it provides guidance regarding where more attention is required. • It improves overall control and monitoring. • It helps in proper labour and material management. • As delay is reduced, it results in saving the cost.
  • 59. Limitations of Critical Path • It does not consider uncertainties in planning. • CPM is not useful for research and development type of project.
  • 61. Project Evaluation and review Technique ( PERT) • PERT Technique considers the uncertainties of the project. • Optimistic time, most likely time, and pessimistic time are the three time estimates used in the PERT. Optimistic time ( to) is the time when all situations are favorable. Most likely time (tm) is the time normally taken for the completion of the activity. • The pessimistic time (tp) is the time when maximum time is taken for the activity to complete due to most unfavorable situation. The expected time is the weighted average of all the above mentioned three time.
