INTRODUCTION
ABOUT THE ORGANISATION
Larsen & Toubro Limited is the biggest legacy of two Danish Engineers, who built a
world-class organization that is professionally managed and a leader in India's
engineering and construction industry. It was the business of cement that brought the
young Henning Holck-Larsen and S.K. Toubro into India. They arrived on Indian
shores as representatives of the Danish engineering firm F L Smidth & Co in
connection with the merger of cement companies that later grouped into the
Associated Cement Companies.
Together, Holck-Larsen and Toubro, founded the partnership firm of L&T in 1938,

BRIEF INTRODUCTION OF PROJECT
“Atmosphere,” is a 550-crore luxury residential condominium project whose most
picturesque feature is “Deya,” (means cloud in Bengali), a structure joining the twin
towers of the building. Designed by the Singapore based Arc Studio, it is like a
hanging sculpture at a height of 500 feet. Deya will be 320 feet in width, with 55,000
square feet of usable space and will have a silver lining featuring 15,000 kinetic discs
on its surface to keep it glowing. It will take approximately INR 100 crores to build
just this structure. Upon construction, it will also become one of the most expensive
clubs in India, featuring several swimming pools, a gym, a spa, a few squash courts
and a badminton court, a meandering jogging track, a mini cinema theatre, open-air
party deck, an amphitheater, and multiple lounges and spaces for smaller gatherings.
Only 80 families will get to live in this magnificent condominium.
Forum Group has announced its decision to give Kolkata, and India, a new icon – a
sculpture in the sky. Christened ATMOSPHERE, this luxury residential condominium
project will consist of two tall towers; hanging between them, at a height of 500 feet, is
‘Deya’, an iconic piece of public art that will also house an exclusive club for the
residents of Atmosphere. Spanning more than 320 feet in width, 55,000 sqft in usable
space, Deya will be amorphous in shape, sculpted as if a cloud was gently floating
between the peaks of the two towers.

PLANNING
Construction planning is a fundamental and challenging activity in the management
and execution of construction projects. It involves the choice of technology, the
definition of work tasks, the estimation of the required resources and durations for
individual tasks, and the identification of any interactions among the different work
tasks. A good construction plan is the basis for developing the budget and the schedule
for work. Developing the construction plan is a critical task in the management of
construction, even if the plan is not written or otherwise formally recorded. In addition
to these technical aspects of construction planning, it may also be necessary to make
organizational decisions about the relationships between project participants and even,
which organizations to include in a project.
Planning department in L&T uses Microsoft Project as a powering tool for reducing
risk. Microsoft Project gives efficiency to plan a project, identify the resources
required and identify the tasks required in a sequence, increasing probability of
delivery of the project to the time, cost and quality objectives. Microsoft Project gives
a powerful, visually enhanced way to effectively manage a wide range of projects and
programs.
The key to a successful project is in planning. Planning is the first thing when
undertaking a project. The value of project planning
 saving money
 saving time
 saving many direct and indirect problems
L&T uses MPCS (MANAGEMENT PLANNING AND CONTROL SYSTEM) for
effective monitoring of planning activities / schedules
o S0 – Schedule of work ( Time )
o S1 – Schedule of Invoice ( Money )
o S2 – Milestone schedule (Time )
o S3 – P&M schedule ( P&M )
o S4 – Schedule of Staff ( Supervision )
o S5 – Schedule of Labour ( Labour )
o S6 – Material schedule ( Material )
o S7 – Schedule of Special Agency ( Cost )
o S8 – Schedule of Direct Cost ( Cost )
o S9 – Schedule of Indirect Cost ( Cost )
o S10 – Schedule of Fund ( Cash inflow / outflow )

21
Essential elements for project planning
o Aim of project- What is the end product
o Outputs – what do we actually need to get there?; need to be clearly defined
o Quality criteria – what quality the outputs need to be of?
o Resources – include staff time, particular knowledge or skill sets, money,
time
o Management structure – how are we going to manage the work?; Decision
makers?; How to share project progress and to whom?
o Milestones – how to break up the project? ; break up the project into series of
tasks. A defined milestone will help to identify when each section is
completed
o Tolerances – how far the project stray from the defined targets before
sounding the alarm; will help manage the project without continually seeking
guidance from the top executives
o Dependencies – what need to happen before something else? Understanding
dependencies will help understand the impact of changes in any part of the
project; internal & external
o Risks – what could go wrong?; what could happen that may affect the ability
to deliver the project on time? What can be done to avoid them?
o Scheduling – The scheduling to be in accordance to the project schedule

PROJECT MANAGEMENT
WHAT IS A PROJECT?
A project is thus defined in terms of its distinctive characteristics—a project is a
temporary endeavor undertaken to create a unique product or service. Temporary
means that every project has a definite beginning and a definite end. Unique means
that the product or service is different in some distinguishing way from all other
products or services.
WHAT IS PROJECT MANAGEMENT?
Project management is the application of knowledge, skills, tools, and techniques to
project activities to meet project requirements. Project management is accomplished
through the use of the following 5 processes:
 Initiation
 Planning
 Execution
 Controlling
 Closure
The project team manages the various activities of the project, and the activities
typically involve:
 Competing demands for: scope, time, cost, risk, and quality.
 Managing expectations of stakeholders.
 Identifying requirements.
KEY GENERAL MANAGEMENT SKILLS
Leading: On a project, particularly a larger project, the project manager is generally
expected to be the project’s leader as well. Leading involves:
 Establishing direction
 Aligning people
 Motivating and inspiring
Communicating: Communicating has many dimensions:
 Written and oral, listening and speaking.
 Internal (within the project) and external (to the customer, the media, the public,
etc.
 Formal (reports, briefings, etc.) and informal (memos, ad hoc conversations, etc.

24
 Vertical (up and down the organization) and horizontal (with peers).
Negotiating: During the course of a typical project, project staff is likely to negotiate
for any or all of the following:
 ‰ Scope, cost, and schedule objectives.
 ‰ Changes to scope, cost, or schedule.
 ‰ Contract terms and conditions.
 ‰ Assignments.
 ‰ Resources.
Problem Solving: Problem solving involves a combination of problem definition and
decision-making. Problems may be internal or external. Problems need not necessarily
be technical in nature. They may pertain to managerial or interpersonal issues.
Influencing the Organization: Influencing the organization involves the ability to
“get things done”. It requires an understanding of both the formal and informal
structures of
all the organizations involved—the performing organization, customer, partners,
contractors, and numerous others, as appropriate.
Role of Project Management
 Compliance with Labor Standards
 Compliance with all applicable
Environmental Limitations and Standards
 Compliance with all pertinent
Engineering Standards and Codes

EXECUTION
The project comprises of two towers. Each tower is subdivided into 3 pours or 3 parts.
Simplex Part, Duplex Part and the common part. The speciality of this building is no 3
consecutive floors are exactly same. The geometry of the floors match after every 4th
floor. For e.g 5th
floor has similarity with 9th
and so on. Between the two towers lies
the non-tower region or the basement area and extended basement area. On the 29th
floor there wil be a skybridge.
Surveying
o Laying out respective points on ground from the relevant drawings
specified.
o Setting up of Grid lines with the help of prefixed axes and centre of co-
ordinates.
o Levelling of ground
o Checking verticality
o Shifting Points of reference to specified position and marking positions of
various structures.
Reinforcements
o Laying of reinforcement bars according to drawing.
o Tie-ing of the bars.
o Here colums and shear walls are erected together.
o Two consecutive laps must not be there.
o Lap joints must not lie in region L/3 from the slab.
o Due to congession of reinforcement, the reinforcements are relaid as
necessary and permissble.
o Joints- lap joints, coupler joints
Formwork
o It is a casing that gives shape and support to the concrete in the initial time
of setting.
o Formwork is mainly divided into 3 members – primary, secondary and
sheathing member.
o Sheathing member is the one directly in contact with concrete. Secondary
members are the ones supporting and strengthening the sheathing
members. Primary members support the secondary ones.
o Formwork can be further divided into vertical(columns, walls, etc.) and
horizontal formwork(stairs, beams, slabs,etc.).
o CT-props are used as supporting and load bearing members for horizontal
members whereas for vertical members they are only for alignment
purposes.

33
o There are many systems of formwork viz. Alufo, Doka, aluminium
formwork, conventional formwork, tunnel form shuttering.
o Improvement in formwork system helps the concrete attain strenght, gives
it desired shape and size, and above all the slab cycle/pour cycle depends
on formwork.
o Aluminium formwork is used in this project. It reduced the slab cycle of
30-45days to 7-9 days.

etc.
FORMWORK PANELS
 Cleaning the surface and side panel of the formwork after each usage shall be
done immediately using proper tools.
 Ensure that all front and side panel of formwork is properly coated with
recommended form release agent that prevents from sticking and concrete
buildup aluminium form surfaces. It protects and prolongs the useful lives of the
aluminium formworks.

34
 The following precautions shall be taken when applying the Form Oil on the
aluminium panels.
o The best results are obtained when a uniform application of Form Oil is
applied immediately following stripping and subsequent cleaning of the
panels. Always ensure that the coated form surfaces are allowed to dry prior
to placing concrete.
o Do not over apply. Excess Form Oil can adversely affect performance and
should be picked up promptly with rags.
o Prevent Form Oil overspray from contacting reinforcing steel bars and/or
tensioning cables.
ASSEMBLY OF WALL FORMWORKS
 Pins and wedges are to be used to secure the panels together. Always insert the
pin from the inside out for easy removal of pin after concreting.
 The formwork panels wall positioning is securely placed on the marked gridlines
and level by way of fixing timber stoppers at the base of the outer side of the
formwork panels at interval of one (1) meter. This would ensure that the
formwork panels are not disposition during the concreting process.
 Once the initial wall corner panels are assembled, place the wall corner panels
on the allotted set up position.
 Commence to erect simultaneously the balance of the wall panels from either
side of the external wall panel.
 Proceed to assemble the internal wall corner. Place these panels into the correct
position on the lines which were set up by the surveyor. Proceed to assemble the
balance of the internal wall at both sides.
 The internal and external walls are to be held together by flat wall tie.
 To determine and achieve the vertical accuracy of the formwork panels
assembled before concreting process, several methods such as plumb bob, spirit
level, theodolite equipment etc can be used. The simplified method of using a
plumb bob with a string attached to it which is then suspended from the upper

35
part of the formwork panels is used as a guide to determine the deviation from
the vertical alignment of the panels.
ASSEMBLY OF BEAM & SLAB FORMWORKS
 Fix the slab corner on top of the wall panels with round pins and wedges. The
position of the pins should be from top down to ease the dislodging process.
 The prop stand and prop head is to be connected together for beam and slab
support.
 Alu span and Alu span cantilevers are connected to the Slab prop head using
Beam Splice Bars. They are connected together by long pins and wedges at
bottom section.
 The Aluspan sections are accurately position to enable the slab panels to be
connected systematically.
 Commence to assemble the slab panels from the corner section of the slab.
Subsequently, fixed the whole slab area by pinning the slab panels together with
the Aluspan.

SKY BRIDGE
The Skybridge is a hanging masive structure resting on two towers at great height(29th
foor)
 The hold down bolts and bearing girders are tobe constructed after casting of the 29th
floor.
 Simultaneously the temporary structures are to be built for supporting the Skybridge.
 Temporary structures are to be placed at 7 locations in tower 2 and at 4 in tower 1.
Temporary structures consists of spreader beams and columns.
 After placing the bearing girders, the main bearings are to be placed. As Bearing
structures come late, they are substituted by the temporary structures.
 Then the spine trusses are to be erected. And then the infills between two spine
trusses are needed to be fixed.
 Next the transeverse trusses are to be erected.
 Cat heads are made. Cat heads are temporary structures used to lift the main structure.
 The main structure is to be built at the non tower area and then lifted up with 4 strand
jack system installed at the top floor.
 The members used for girders and bearing girders are all built up sections fabricated
at Tiruchirapally.

CONCLUSION
Today, India is the second fastest growing economy in the world. The Indian
Construction industry is an integral part of the economy and a conduit for a substantial
part of its development investment, is poised for growth on account of
Industrialization, economic development and people’s rising expectations for
improved quality of living.
In India, construction is the second largest economic activity after agriculture.
Construction accounts for nearly 65% of the total investment in Infrastructure and is
expected to be the largest beneficiary of the surge in infrastructure investment over the
next five years. The major investments are likely to be in power, roads, bridges, city
infrastructure, ports, airports, telecommunications, which would provide a huge boost
to the construction industry as a whole.
With the significant investment opportunities emerging in this industry, a large number
of international real estate players have entered the country.
The construction industry witnessed a slowdown in FY12, after the economy showed
some resilience in the preceding two years. The growth in the construction industry
dipped to 4.8% in FY12. Project financing also became difficult on the back of the
increasing gestation periods of the projects, thereby leading financial institutions to
take a cautious approach towards funding projects in the sector.
The FY2012/13 had a growth of 6.0% for the Indian construction sector. Due to
monetary issues and other related policies the Indian construction industry showed a
lackluster performance in 2012-13. But the outlook for the construction sector beyond
FY2012/13 is brightening up. Not only are monetary conditions likely to improve for
construction companies in FY2013/14, but the government is also making pertinent
efforts to remove bottlenecks that are delaying infrastructure projects in India. India's
construction sector is to reach 7.6% growth in FY2013/14.
