Introduction
The basics needs of human existences are food, clothings & shelter. From times immemorial
man has been making efforts in improving their standard of living. The point of his efforts has
been to provide an economic and efficient shelter. The possession of shelter besides being a
basic, used, gives a feeling of security, responsibility and shown the social status of man. Every
human being has an inherent liking for a peaceful environment needed for his pleasant living,
this object is achieved by having a place of living situated at the safe and convenient location,
such a place for comfortable and pleasant living requires considered and kept in view.
A Peaceful environment.
Safety from all natural source & climate conditions
General facilities for community of his residential area.
The engineer has to keep in mind the municipal conditions, building bye laws, environment,
financial capacity, water supply, sewage arrangement, provision of future, aeration, ventilation
etc., in suggestion a particular type of plan to any client.
Induction
Safety is very important part of any work. Most accidents can be prevented by taking simple
measures or adopting proper working procedures. It is very important to discuss issues on safety
and health that should be paid attention to on construction sites for easy reference by the
workers. If we work carefully and take appropriate safety measures, there will definitely be
fewer work injury cases, and our sites will become a safe and secure place to work in. It is
important to educate everyone in the site regarding safety for following purposes.

ISO 14001-2004
OHSAS 18001-2007 Precautions at site for safety-
Wear protective equipment.
On the first day of my training, the first task that was carried out was Safety Induction. We had
to fill the induction form and then we were provided with helmets and shoes.
Storage
Make sure material are protected from the weather stored correctly .
Factory goods- These are mostly used items and they are unique and also delicate in the fact
that need unique storage required .
Types
Cement
Ceramics
Iron
Raw material
Construction equipment
1. Tower crane
They are rise 100 ft. or more . they are used to lift steel ,large tools, generators, etc.
Max. height of crane 265ft.
Max. lifting power - 19.8tonnes
Bar bending machines
This machines used to make the desired shape of reinforcement .
They taught us how much steel is required for making a ring.
For example- There is a 500mm*500mm beam and a rectangular ring is to be designed,
then taking a clear cover of 50mm, length of steel required is
500-50=450
450*4=1800
200mm for overlapping, and subtracting 75mm due to elongation in bending.
So total length for rectangular ring =1800+200-75=1925mm.
For a circular colomn of 600mm diameter-
Taking 80mm cover,
Length =520*3.15=1638mm
400mm for overlapping.
Total =1638+400=2038mm
Monkey crane
This machine used to lift the small weight materials like bricks , other materials.
Conctete mixer
This is used to mix the concrete at the site . All the materials like cement, concrete, water
and sand are put into it and then rotated.
When it is properly mixed, then it is sent at construction site within time.
Batching plant ( design mix plant) and quality control
Quality control is a part of quality management that ensures product quality .
Various tests are conducted before applying materials to the work.

DRY MIX
In dry mix the water is added to the concrete after washing to the construction site.
In concrete batching plant ingredients of concrete are mixed and transported to site by transmit
mixture
WET MIX
Waste of all chemical bag are cut and with the help of a pipe cement enter into the huge conical
shape containers.
After pouring cement with the huge spoon aggregate are scooped sieved and poured into huge
tank.
After that required quantity of the water is added and the whole mixture is shifted to transit
mixture.
BEAMS AND COLUMNS
In framed structure fixed type beams are constructed. In such type of beams proper
reinforcement should be done for positive as well as negative bending moments. In square or
rectangular shaped columns min. 4 nos of 12 mm diameter bars must be used and spacing
should not be more than as per code IS 456:2000. Fixed type beam constructed at site with
positive as well as negative reinforcement
Columns are provided with drop panels to reduce punching shear.
They were provided at site.
Surveying
There are different type of surveying done on the site , these are as following as.
Auto level

Facad surveying
A surveying engineer told us how he was carrying out the survey.
They pepared a drawing there with different points on the tower for facad at different
points.
They said that they will draw this on AutoCAD.
Surveying was done using Total Station.
Drawing study
A civil drawing, or site drawing, is a type of technical drawing that shows information about
grading, landscaping, or other site details. These drawings are intended to give a clear picture of
all things in a construction site to a civil engineer.
Civil drafters prepare drawings and topographical and relief maps used in major construction or
civil engineering projects, such as highways, bridges, pipelines, flood control projects, and water
and sewage systems

Pre-tensioned (PT) slabs
Pre-tensioned (PT) slabs are typically flat slabs, band beam and slabs or ribbed slabs. PT slabs
offer the thinnest slab type, as concrete is worked to its strengths, mostly being kept in
compression. Longer spans can be achieved due to prestress, which can also be used to
counteract deflections.
Pre-tensioned slabs use high-strength tensioned steel strands to compress the slabs, keeping the
majority of the concrete in compression. This gives a very efficient structure which minimises
material usages and decreases the economic span range when compared to reinforced concrete.
Benefits

Facades work
Building facades are one of the largest, most important elements in the overall aesthetic and
technical performance of a building Faade engineering is the art and science of resolving
aesthetic, environmental and structural issues to achieve the effective enclosure of buildings.
Specialist companies are dedicated to this niche sector of the building industry and engineers
operate within technical divisions of faade manufacturing companies. Generally, faade
engineers are specifically qualified in the discipline of faade engineering and consultants work
with the design team on construction projects for architects, building owners, construction
managers and product manufacturers.
Faade engineers must consider aspects such as the design, certification, fabrication and
installation of the building faades with regards to the performance of materials, aesthetic
appearance, structural behaviour, weathertightness, safety and serviceability, security,
maintenance and build ability. The skill set will include matters such as computational fluid
dynamics, heat transfer through two- and three-dimensional constructions, the behaviour of
materials, manufacturing methodologies, structural engineering and logistics.
Over time, the specialist skills necessary in this niche sector have surpassed the capabilities of
architects, structural and mechanical engineers as buildings are designed with more complexity
and with the introduction of Building Information Modelling (BIM).
Building faades are considered to be one of the most expensive and potentially the highest risk
element of any major project. Historically building facades have the greatest level of failure of
any part of a building fabric and the pressure for change and adaptation due to environmental and
energy performance needs is greater than any other element of a building. As a consequence
faade engineering has become a science in its own right
Design mix plant
A concrete plant, also known as a batch plant or batching plant or a concrete batching
plant, is equipment that combines various ingredients to form concrete. Some of these inputs
include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag,
and cement. There are two main types of concrete plants: Dry mix plants and Wet mix plants, and
also plants that contain both a transit mix side and a central mix side while utilizing common
material storage points. A concrete plant can have a variety of parts and accessories,
including: mixers (either tilt drum or horizontal or in some cases both), cement batchers,
aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers,
cement silos, batch plant controls, and dust collectors.
Materials used for construction at Site
At the construction site following materials were being used
Cement
The function of cement is to combine with water and to form cement paste. This paste first sets
i.e. it becomes firms and then hardens due to chemical reaction, called hydration, between the
cement and water. On setting & hardening, the cement binds the aggregate together into a stone
like hard mass & thus provides strength, durability & water-tighten to the concrete. Quality of
cement is based on grade of cement. The grades of cement are as-
1. 33 Grades
2. 43 Grades
3. 53 Grades
The initial setting time of cement = 30 minutes (1/2 hr.)
The final setting time of cement = 10 hrs
Aggregate
Aggregates are small pieces of broken stones in irregular size and shapes. Neat cement is very
rarely used in construction works since it is liable to shrink too much and become cracks on
setting. Moreover, it will be costly to use neat cement in construction work. Therefore cement is
mixed with some inert strong & durable hard materials. They also reduce the cost of concrete
because they are comparative much cheaper as cement.
Types of aggregates:
1. Fine Aggregate
2. Coarse Aggregate
Fine aggregate (sand)
The aggregate, which pass through 4.75 mm, I.S. sieve and entirely retain on 75 micron
(.075mm) I.S. sieve is known as fine aggregate.
The function of using fine aggregate in a concrete mix is to fill up the voids existing in the
coarse aggregate and to obtain a dense and strong concrete with less quantity of cement and
increase the workability of the concrete mix.
Coarse aggregate
The aggregate, which pass through 75 mm I.S. sieve and entirely retain on 4.75 I.S. sieve is
known as coarse aggregates. At construction site aggregate used are as follows Coarse
aggregate of 20mm size. Coarse aggregate of 12.5 mm size (As per concrete mix design). Fine
aggregate in form of coarse sand.
Reinforcement
The material that develops a good bond with concrete in order to increase its strength is called
reinforcement. Steel bars are highly strong in tension, shear, bending moment, torsion and
compression. At the construction site using the high strength steel bars and T.M.T. (Thermo
Mechanically Treated) bars of diameter 8 mm, 10 mm, 16 mm, 25mm & 32 mm as per
requirement of design were being used. The bars were of grade Fe415 for 8mm and Fe500 for
other diameter bars.
Fly ash
At the site, a small amount of fly ash was also being used which is produced by burning of coal
in thermal power plants.
The main advantages of using fly ash in building construction are as follows-
1. It is free of cost.
2. Its consumption reduces environmental pollution.
3. It has a fair quality of bonding properties.
It was stored in a container placed at a height and it was mixed in concrete.
Admixtures
Admixtures are generally used to affect workability of concrete mix and to reduce water content.
Admixtures also increases the target mean strength of concrete.
Water Proofing
Water-proofing is a process which is designed to prevent water from penetrating a building.
Usually extensive waterproofing measures are added to a building at the time of construction, to
provide moisture control from the start
Water proofing may also be done after a building is built, to address problems as they emerge or
as part of a building retrofit.
Water proofing is done in various parts of the building which include-
1. WC
2. Bathrooms
3. Terrace
4. Roofs and Chejjas
5. Basement, swimming pools, underground ducts.
6. Under ground and overhead water tanks. Water-proofing maintains the appearance of the
building and increases the life of the structure
Formwork
Formwork in concrete construction is used as a mould for a structure in which fresh concrete is
poured only to harden subsequently. Types of formwork for concrete construction depends on
formwork material and type of structural element.
A good formwork should satisfy the following requirements:
It should be strong enough to withstand all types of dead and live loads.
It should be rigidly constructed and efficiently propped and braced both horizontally and
vertically, so as to retain its shape.
The joints in the formwork should be tight against leakage of cement grout.
Construction of formwork should permit removal of various parts in desired sequences
without damage to the concrete.
The material of the formwork should be cheap, easily available and should be suitable for
reuse.
The formwork should be set accurately to the desired line and levels should have plane
surface.
It should be as light as possible.
The material of the formwork should not warp or get distorted when exposed to the
elements.
It should rest on firm base
