clearance which involves removal of grass and

vegetation along with any other objections

which might be there in the site location.

Layout for Excavation: - As the metro line

tunnel passes below the construction area so

coordinates are referred from INA Metro

Station. Two arbitrary station points of known

coordinates with reference to INA Metro

Station Benchmark were marked with the help

of a TOTAL STATION, thread and plumb bob

as per the grid drawing near every block to be

constructed.

Methodology Of Work

Page 14: Re development works at east kidwai nagar, New Delhi

Laying of P.C.C. (Plain Cement

Concrete):- After the process of

compaction and levelling, laying of

plain cement concrete that is PCC is

done. A layer of 100mm thick PCC of

grade M10 with 100mm projections was

made in such a manner that it was not

mixed with the soil. It provides a solid

base for the raft foundation and a mix of

1:4:8 that is, 1 part of cement to 4 parts

of fine aggregates and 8 parts of coarse

aggregates by weight were used in it.

Plain concrete is vibrated to achieve full

compaction.

Waterproofing:

The roof covering materials, siding,

foundations, and all of the various penetrations

through these surfaces need to be water-

resistant and sometimes waterproof.

APP Membranes

APP Membranes:

APP Waterproofing Membranes are

mostly used to prevent leakage in

various areas.

Methodology Of Work

Non-woven Fabric

Non-woven fabric is a fabric-like material

made from long fibers, bonded together

by chemical, mechanical, heat or solvent

treatment.

This fabric is used over APP membrane to

prevent its puncturing due to

reinforcement and concrete.

Retaining wall:

A retaining wall is a structure designed

and constructed to resist the lateral

pressure of soil when there is a desired

change in ground elevation that exceeds

the angle of repose of the soil.

Methodology Of Work

Laying of Beam and Slab:

A structural member which supports

lateral load and resist bending is known as

beam. Slabs are plane structural member

whose thickness is quite small as

compared to its other dimension. Slab

support mainly transverse loads and

transfer them to end supports by bending

action in one or more directions. Laying of Beam and Slab

Methodology Of Work

What Is the Difference Between Shuttering and Formwork?

Shuttering and formwork are both terms used to describe the

process of creating a mould in which concrete can be poured and

contained as it hardens. Shuttering usually refers to the process of

using plywood to form the mould, while formwork is something of a

broader term that is used to denote the forming process using a wide

variety of materials. Shuttering and formwork both accomplish the

same essential task, but the materials used to accomplish this task

can vary. Sometimes there is no differentiation made between the

two terms, and in some cases, shuttering may be considered one

specific type of formwork.

Page 22: Re development works at east kidwai nagar, New Delhi

Methodology Of Work

Filler Board:

This is capable of expansion and contraction

which occurs with seasonal variations in

temperature and are generally placed

between two slabs or columns. Features of

filler board are affordable, effective, and

reliable

Filler Board Waterbar:

The function of waterbar is to seal the joint

against water penetration. Waterbars may be

necessary where the joint is subject to

groundwater pressure or where the method of

construction makes it difficult to accurately

seal the surface cavity, and where it is very

essential that there shall not be any risk of

penetration of water.

Waterbar

Page 23: Re development works at east kidwai nagar, New Delhi

Methodology Of Work

Waterbars may be of natural and

synthetic rubber, polyvinylchloride (PVC)

or metal. The strips shall be supplied in

uniform lengths of 2.5 to 3.5 m at the

option of the manufacturer, unless

otherwise ordered

below:

• Slump Test

• Compressive Strength of Concrete

• Weight of Steel

• Silt Content

• Grading of Aggregate

• Impact Value Test

• Compressive Strength of Brick

• Water Absorption Test

• Dimensional Tolerance

• Determination of Moisture Content by Calcium Carbide

Method

• Core Cutter Method

Page 26: Re development works at east kidwai nagar, New Delhi

Quality Control and Testing

Determination of moisture content by using calcium carbide.

This test is done to determine the water content in soil by calcium carbide method

as per IS: 2720 (Part II) – 1973. It is a method for rapid determination of water

content from the gas pressure developed by the reaction of calcium carbide with

the free water of the soil. From the calibrated scale of the pressure gauge the

percentage of water on total mass of wet soil is obtained and the same is converted

to water content on dry mass of soil.

Apparatus required :-

i) Metallic pressure vessel, with a clamp for sealing the cup, along with a gauge

calibrated in percentage water content.

ii) Counterpoised balance, for weighing the sample.

iii) Scoop, for measuring the absorbent (Calcium Carbide).

iv) Steel balls – 3 steel balls of about 12.5mm dia. and 1 steel ball of 25mm dia.

v) One bottle of the absorbent (Calcium Carbide).

Quality Control and Testing

Procedure to determine Water Content In Soil By Calcium Carbide Method

• Set up the balance, place the sample in the pan till the mark on the balance

arm matches with the index mark. • Check that the cup and the body are clean.

• Hold the body horizontally and gently deposit the leveled, scoop-full of the

absorbent (Calcium Carbide) inside the chamber.

• Transfer the weighed soil from the pan to the cup.

• Hold cup and chamber horizontally, bringing them together without disturbing

the sample and the absorbent.

• Clamp the cup tightly into place. If the sample is bulky, reverse the above

placement, that is, put the sample in the chamber and the absorbent in the cup.

• In case of clayey soils, place all the 4 steel balls (3 smaller and 1 bigger) in the

body along with the absorbent.

• Shake the unit up and down vigorously in this position for about 15 seconds.

Page 29: Re development works at east kidwai nagar, New Delhi

Quality Control and Testing

• Hold the unit horizontally, rotating it for 10 seconds, so that the balls roll

around the inner circumference of the body.

• Rest for 20 seconds.

• Repeat the above cycle until the pressure gauge reading is constant and note

the reading. Usually it takes 4 to 8 minutes to achieve constant reading. This is

the water content obtained on wet mass basis.

• Finally, release the pressure slowly by opening the clamp screw and taking the

cup out, empty the contents and clean the instrument with a brush.

Safety Measure and Campaign

• In Civil engineering construction

project, accidents cannot be avoided.

• A mishap can happen any time and

unexpectedly during construction.

• About 80 percent of accidents are

mainly caused due to unsafe

practices and shear negligence of the

workers. • Safety measures are necessary to motivate and

encourage the workers to work at the given site or

industry without any fear, tension or worry in

mind about his security of life.

• Good safety measures are essential to

increase the output of work by

generating safety free environmental

sense of contentment among the

workers.

TECHNOLOGY

• Producing the Bricks by Using Enzymes.

• The EN-2 Enzyme is a synergistic mixture of enzymes, coenzymes, binders,

catalysts, wetting agents, surfactants and water. It is non-toxic and non

combustible. It does not harm humans, animals, fish or vegetation under

normal use and is totally biodegradable process. EN-2 have been tailored to

provide the "lock" for numerous soil and other organic materials and

promote the desired alteration of their properties, causing a rapid

cementation process to occur.

The Advantages of Using EN-2 in the Brick Manufacturing

• Reducing the cement quantity up to 50%.

• Reducing the cost of manufacturing the brick.

• Reducing water absorption in the brick.

• Maintaining the strength of the product.

• Reducing water use during the process.
