It explains that a project is a temporary endeavor to create a unique product or service, with a definite beginning and end. The video outlines the five phases of a construction project: briefing, designing, tendering, construction, and commissioning. Each phase's purpose and activities are detailed, emphasizing the importance of planning and coordination to ensure projects are completed on time, within budget, and to the required quality.
Takeaways
- 🏗️ The construction project is defined as a temporary endeavor to create a unique service, product, or result.
- 🌐 A project can be anything from building a structure to planning a vacation, but construction projects are specifically focused on creating physical structures like buildings, bridges, or dams.
- 📚 The PMBOK (Project Management Body of Knowledge) defines a project as temporary and unique, emphasizing that projects have definite beginnings and ends and are different from one another.
- 🛠️ ISO 1006 defines a project as a unique process consisting of coordinated and controlled activities to achieve objectives under constraints like time, cost, and quality.
- 🔍 The briefing phase, also known as the report stage, is where project ideas are generated and evaluated for economic viability and social utility.
- 🎯 The purpose of the briefing phase is to specify project functions and costs, and to interpret the owner's wishes to estimate the project's cost.
- 📈 The feasibility report contains technical, economic, financial, and ecological analyses to determine if a project is feasible in various aspects.
- 📊 Technical analysis in a project checks the site selection, construction methods, resource availability, material specifications, and construction equipment selection.

🏗️ Introduction to Construction Management
The session begins with an introduction to construction management, focusing on the first topic: the nature of a construction project. The instructor clarifies that a project can be any endeavor, such as building infrastructure or even planning a vacation. Technically, a project is defined by PMBOK as a temporary endeavor to create a unique product, service, or result. The terms 'temporary' and 'unique' are emphasized, indicating that projects have definite starts and ends and are distinct from one another. ISO 1006 also defines a project as a set of coordinated and controlled activities with specific requirements and constraints like time, cost, and quality.
📈 Understanding the Phases of Construction Projects
The lecture continues with an exploration of construction management, defined as the coordinated effort of various professionals to complete a project economically without compromising quality. The phases of a construction project are then outlined: briefing, designing, tendering, construction, and commissioning. The briefing phase, also known as the report stage, is where project ideas are generated and evaluated for economic viability and social utility. The purpose of the briefing phase is to specify project functions, permissible costs, and to estimate the project's cost.
📋 The Briefing Phase: Initiating a Construction Project
The briefing phase activities are detailed, including appointing a project steering committee and a project manager, investigating technical and non-technical aspects of the project, identifying feasible alternatives, and preparing a project report. The feasibility report, a key deliverable of this phase, assesses the project's technical, economic, financial, and ecological viability. The report guides decisions on whether to proceed with the project, considering its potential impacts and requirements.
📊 Analyzing Feasibility: Technical, Economical, Financial, and Ecological
This section delves into the four types of analyses conducted for a feasibility report: technical, economical, financial, and ecological. Technical analysis examines site selection, construction methods, resource availability, and equipment selection. Economical analysis evaluates the project's potential for profit and value for money using methods like payback period and return on investment. Financial analysis estimates capital costs and identifies funding sources. Ecological analysis assesses environmental impact, especially for major projects like power plants and chemical industries, ensuring government approvals are in place.
📘 Designing Phase: Planning the Construction Project
The designing phase, also known as the planning stage, is crucial for finalizing project plans and preventing costly changes later. Activities in this phase include completing the project summary, finalizing construction methods and equipment, preparing working drawings, specifications, and a preliminary construction program. The goal is to obtain the client's final approval before proceeding to the next phase.
📑 Tendering Stage: Contracting for Construction Work
The tendering stage involves inviting bids from contractors, pre-qualifying them, preparing contract documents, arranging pre-bid meetings, negotiating prices, reviewing submitted documents, and clarifying ambiguities in the contract. The primary aim is to appoint contractors to carry out the construction work based on mutual understanding and the lowest bid.
👷♂️ Construction Stage: Executing the Project
The construction stage is where the project is physically built, with a focus on adhering to design drawings, specifications, time limits, budget, and quality. This stage is resource-intensive and requires careful planning and control of site operations. Activities include construction planning, material supply, quality supervision, coordination between agencies, and supply of necessary drawings to ensure the project is completed on time and within budget.
🔍 Commissioning Stage: Evaluating Project Performance
The commissioning stage evaluates the structure's performance and considers maintenance and repair needs. Its main purpose is to ensure the construction aligns with design drawings and specifications and that all project facilities and functions operate correctly. Activities include recording actual activities, inspecting construction for defects, preparing operation and maintenance manuals, and conducting performance tests.
📞 Closing Remarks and Contact Information
The session concludes with the instructor offering contact information for any queries or doubts, summarizing the key points covered in the session, and reinforcing the importance of understanding the stages of construction management.

hello everyone
welcome to the first session of the
subject construction management
and today we are going to start with the
first
topic or the first chapter that is
introduction or we can say
introduction to construction management
so without wasting much time let us see
what are the contents of today's session
so today in this session we are going to
see
two topics the first is what is project
and the second is
phases of a construction project yes
so today we are going to see two topics
now though you know the definition or
you know that
project what is project project is to
like in
in terms of construction we can say that
a project is to construct something
like building bridge road dam
that what we construct we call it as
project
but in terms of in if i define it
technically that is very broad
uh the definition of the project
apart from it we can say that everything
and anything can be termed as project
even if you are planning a vacation to
goa that is also a project
so now let us see the technical
definition of the
project let us see so students
here i have defined the project occurred
in two ways
the first is as per p m b
o k p m i that means project
management body of knowledge pmi project
management
institute that is one of the renowned
bodies
of project management established in usa
that is like godfather of the all the
project managements
so according to them a project is
a temporary endeavor undertaken to
create
a unique service product or result
so in terms of construction that could
be a building
that could be a maintenance project or
that could be in construction of
high road highway or other
infrastructure project
so a temporary endeavor
undertaken to create a unique product or
service
there are two terms i have highlighted
here temporary
and unique let us see what they mean
so the term temporary means
every project has the definite beginning
and the definite end yes that means the
projects are temporary
once the project is completed that
becomes a building or that becomes a
product
whichever it is building is just an
example if it is in road
once the why it is being constructed
that is known as road project
but once it is done that is known as
only road
so that is temporary that projects are
temporary
it has definite beginnings and definite
ends
the second is unique the term
unique means every project is
different in some or other way from the
other project
yes every project is different than the
other projects
so that means if you are constructing
one residential building and if you
and another residential building these
two projects are unique
because the features the area the land
the orientation means something will be
different
so that is the unique i hope we are
clear about it now let us see
the definition according to the i a
so 1006
so according to the iso 1006
it is a unique process consisting of
coordinated and controlled set of
activities
having some start and finish dates to
achieve the
objective conforming to the specific
requirements
under the certain controns such as time
cost and project quality students
so the first definition as per the pmbok
we pronounce it as pmbok project
management body of knowledge
so uh in the definition of pmbok the
temporary and unique
what they were mean that is written in
the definition of as per
iso that that it is a controlled set of
coordinated activities which has
start and finish dates and
also they have the constraints like time
cost and project quality apart from it
entire project is undertaken to
obtain to obtain one objective
or specific requirement of the owner of
the
client so that is our definition of
technical definition of
project i hope we are clear up to this
point
moving forward now let us see
that phases of construction project
but before we move ahead in our
second topic that what are the phases of
uh construction project
let us learn the definition of
construction management
we have learned the definition of
project now
let us learn the definition of
construction management
so again there are two definitions
the first is the management in which
group of people of different categories
work together to complete the project
economically
without affecting the quality
in well-planned and organized manner so
that is our
construction management where the group
of people comes together
try to complete the project as per the
technical requirement and
economically in well-planned and
organized
manner while the second definition of
the construction management or we can
say project management
is the application of knowledge
skills tools and techniques to
a broad range of activities to meet the
requirements of the particular
project or to complete a particular
project so again
more or less both the definitions are
the same so that is our construction
management or you can say
project management now let us look at
what we are
what we are going to learn phases of
construction
project let us see so here are the
phases of construction project there are
five phases
the first is briefing then there is
designing
then tendering the fourth is
construction and the last
is commissioning and
other way you can define or you can
classify
the phases of project as
pre-construction
construction and post construction but
to be to study them into detail where we
are going to divide them into
five parts i am repeating it again
briefing
designing tendering construction
and commissioning let us see each of the
phase
one by one starting with the briefing
phase so the briefing
phase or we can say briefing stage is
also known as
report stage in this stage
where the ideas are originated and
evaluated on the basis of cost and
benefit
to study the economic viability
and social utility of the project
so that is the first stage we can say
that that is a
report stage in which ideas are
generated
and those ideas or alternatives to do a
project
are evaluated economically
as well as socially so that is your
report stage i hope we are very clear
about it is the first
beginning stage briefing now
let us look at the purpose of having the
briefing stage or the report stage
let us see the purpose so there are
mainly
two purposes of this briefing stage
the first is to enable the client or the
owner
to specify the project function
and permissible cost yes
in this stage the project function that
by this project
what client actually wanted to do what
his vision is
what his thinking is so that is that is
what
we can do in this briefing stage
as well as to fulfill that functions of
that project
what are the permissible cost and budget
available with the client
the second purpose of this stage is to
enable the construction team
to interpret the owner's wishes and
to have estimated cost of the project
yes by knowing the requirements of the
client the construction team the
consultants
can derive the estimated cost of the
project
so here are the two purposes now let us
see
the activities which are being done in
the
briefing stage let us see so the first
activity is appoint a project
steering committee that means the
committee of the people
will guide the project generally these
are the architects owner and the
consultants the next is appoint the
project
manager a project manager who will be
responsible for the execution of the
work as well as the coordination between
the
various agencies while undertaking the
work
next to investigate
technical and non-technical aspect of
the project
then to study the various projects
and to identify
the most feasible one and
the last is to prepare and project
report so these are the activities which
are involved in the briefing stage
that you appoint a project steering
committee and appoint a project manager
technical and non-technical
investigation list out all the
alternatives and try to
analyze the most feasible one and then
the preparer project
report so that all the things are being
covered in the
briefing stage now after this
all of activity is being done
feasibility report is being prepared in
the briefing stage
now what is feasibility report that
feasibility
the project is feasible or not we should
do it or not
what are the consequences financially
economical
financial or economically socially
environmentally
technically so it is possible or not we
should do it or not so that is your
feasibility analysis or feasibility
report
so that you have to prepare so what is
it let us see
it contains the result of the technical
aspect technical analysis as well as the
environmental analysis
so that the client client or the
consultant
can design the project properly and can
plan the project properly
so as it does not harm the client the
consultant the user as well as the
environment so that is the feasibility
report
now feasibility reports contains this
four parts what are they
let us see so mainly this four kind of
analysis are done
the first is technical analysis the
second is
economic analysis the third is
financial analysis and the last is
ecological
ecological analysis technical
economical financial and ecological
now let us see each of them into detail
but before we start this type of this
analysis into detail let us see a flow
diagram so this is a proper
flow diagram for the feasibility
analysis
the flow for the flow diagram suggests
that
first generate the ideas then there is
an
initial screening of these ideas once
initial screening are done ask
that does this idea is looking primer
facing
the first impression of the primer
facing that means
the first impression of the project is
good if it is good
then move ahead if it is no then
terminate the
idea once the first impression of the
idea is good
then plan for the feasibility study
in feasibility study the first do the
technical
analysis then you conduct financial
analysis
and then you do economical and
ecological analysis after all the
analysis being done
is the project is worthwhile if it is
yes then continue if it is no
then terminate the project and if it is
yes
then prepare the funding proposal for
the
project so this is the flow diagram for
the
feasibility report now let us start with
the first
stage that is technical analysis let us
see
so here is the technical analysis in
technical analysis various
technical aspect of the project is being
checked such as
selection of the site selection of the
appropriate method of construction
availability of various resources and
raw materials
then specification of that raw materials
and the last is selection of
construction
equipment so these all parameters have
been checked as a part of
technical analysis moving forward
the next is economical analysis
so the economical analysis consists that
you have to check if the project is
technically permissible
but you have to see that it is
economically possible
does it is going to on on you on you the
profits
does it is value for money that is your
economical analysis
in economical analysis the project is
evaluated by the various methods such as
payback period method return on
investment method
and the benefit cost matter so these are
the economical analysis which are being
done on the project
sometimes it may happen that a project
is technically possible
but economically not possible so the
client must
not go for the project if it is
economically not possible because
what if it is not economically possible
is not going
to get the returns out of that project i
hope
we are clear up to this point the next
is
financial analysis so the financial
analysis of a project
consisting of estimation of capital cost
requirement and the source of fundings
estimate of capital cost requirement
that is cost of materials cost of
resources cost of equipment
engineering fees supervision charge etc
so that is estimate cost of your
of your work and the second is source of
finance
that all the payments are going to be
done once you work
but to get the work done you have to put
your some amount of money so
source of funding are you going to take
loan are you going to
get something on mortgage or you're
going to put the money
on yours by yourself so what are the
source of fundings that are being
evaluated in the
financial analysis and the last stage is
ecological analysis let us see so
ecological analysis that means the
environmental
impact assessment which is being done on
the major projects such as power plant
major irrigation projects chemical
industries
drug industries etc on this kind of
projects the ecological assessments are
being done
and the certain government approvals
should be taken
so this is what we done in the briefing
stage while making the
feasibility report i hope we are
very much clear this was the first stage
briefing
in briefing we have to prepare the
feasibility feasibility as
four type of analysis technical
financial
economical and ecological now
let us see the second phase that is
designing phase of the construction
project
so this designing stage of the
construction project
is being also known as the planning
stage
students do not misconcept misinterpret
the word
design design does not means you have to
prepare the drawings
design that means you have to plan the
project that how you will do the things
how you will manage the things that is a
designing phase
that means it is one of the important
phase because
in this stage you are going to finalize
your plan
you are going to finalize your things to
do the work
so a small change after this stage
would be expensive pardon me would be
very expensive to you because you are
fixing the things how it is being done
so now you have to you you
once the change is being done it will be
very expensive
so that is very critical stage here in
this stage a realistic
and detailed cost estimate is being
prepared for the
project now let us see the purposes of
this
stage so here are the purposes of the
this kind of this stage is that to
prepare the project to complete the
project summary
to finalize the method of construction
the equipments
to prepare the working drawings for the
project
for the preparation for the preparation
of the specifications of the different
item of work
and for to prepar to make the necessary
arrangements to invite the
tenders so these are the purposes of the
designing stage now let us look at the
activities
involved in the designing stage so
so the purpose is and the activities are
more or less similar that to complete
the project report or the project
summary
then to carry out the further technical
investigations that now you are going
with this method
of this method of construction what can
happen what are the consequences
then to prepare the drawings
specifications
boq and preliminary construction program
and the last is to obtain the client's
final
approval so these are the activities
being done in the designing
stage let us look at the next stage
the next stage of the construction
project is
tendering stage tendering stage you have
been already learned
in the professional practice and
valuation subject that in this
stage of the construction the tenders
are invited from the contractors
to undertake the work and the work is
awarded to the lowest
parties by the mutual understanding of
the contractor and the
client the main purpose is very much
known that to appoint a contractor or
appoint the
various contractor number of contractors
to do the construction
so that is the purpose of the tendering
stage
let us see the activities
involved in the tendering stage
so here are the activities which have
been performed in the
tendering stage the first activity is to
invite the tenders
and to perform the pre-qualification
process of the contractors
the second is to prepare the necessary
contract documents
and to arrange a pre-bid meeting to
provide the necessary information
regarding the project
the next is negotiating the price with
the contractor
then the review of the documents
submitted by the contractor
and the last activity which is being
done in the stage
is clarify the ambiguities
in the contract documents ambiguities
means some of the doubts which are being
unclear
so that clarity of ambiguity is in the
contract document so these are the
tendering stage moving forward
the next stage the fourth stage is
construction
stage in the construction stage you know
that
the execution of a construction
execution of a project
takes place now the execution must be
done
according to the design drawing
specification
that to within the time limit budget
and required quality that we have to
take care in the construction
uh construction stage that a project
with completes within the time
completes within the cost achieve the
specific requirements
uh stated by the client quality should
be maintained
so that is the that is the most
resource incentive stage that more
resources will be allocated in this
stage
now in construction stage various
activities
will be interrelated to each other so
delay in one activity will lead to the
failure of entire project or delay
number of activity
and you cannot complete the work within
the time and
cost so you have to take care of that
that here
the activities will be interrelated for
an example
for an example the slab
the construction the formwork of slab
and the steel cutting
these are two activities which are
interrelated to each other while the
shuttering is being done
you have to cut the steel for your slab
if it is not done
parallely if you are going to after it
you are not going to complete the work
within the time
so i hope you are getting my point
so that is your construction stage now
in construction stage
mainly two things are done what are they
let us see
the first part is construction planning
in construction planning generally you
prepare the construction steel
you prepare the material schedule
manpower and other resource schedule and
plant and equipment
schedule so you do the planning first
while the constructing you do the
planning first
the second is control of control of
site operation the control of site
operation consists
of supply the materials so
supply uh supply the materials supervise
the supervisor over the quality of the
work
coordinate between different agencies
and different contractors
and supply the necessary drawings so
this is the control of
control the site operations first you do
the planning and then you
try to control the site operations so
that your project can be finished within
the timing cost and
quality now let us see
the last stage which is
commissioning stage let us see in this
stage
the performance of the structure is
being evaluated and the proposed
nature of maintenance and repairs
are considered the main purpose of this
stage
is to investigate that the construction
has been done according to the design
drawing and specification
and all the facilities and functions of
the project are
working correctly so that is the main
purpose of this
commissioning stage let us see the
activities in this stage
so the first activity is to keep the
record of the various
actual activities the second is to
inspect the construction thoroughly
and rectify any defect the next is
to prepare the operating and maintenance
manuals
and the last is to carry out the
performance test so these are the
activities which have been done on the
commissioning
stage so there are five stages of the
construction briefing
designing tendering commissioning
construction and then commission five
stages and you have to
prepare in that order only because once
first
you have to do the first in the real
time project the briefing is done
then the designing or the planning is
being done then the
tendering is being done then the
construction and the last is
commissioning
so you have to prepare in that order
only
so i hope we are clear very much in that
first
session so this is it that was all about
in today's session
in case of any query or doubt you can
always contact me in my mail or my
number
thank you
