Complete Construction of RCC Design
Construction
of RCC design
Construction
of RCC building required some of paperwork
before the start of Actual construction The very first stage is
preparation of drawings as per requirements
of client, once drawings are completed, approval of drawings is
important of drawings from both architect as well as structural
engineer the next step, is marking of plat
boundaries, you cleaning a plot site preparation sis of clearing
away the trees from your building site this involves the removal of
trees roots and other vegetation from the building site after cleaning
the site plot marking of plot should be done as per drawings.
Excavation
Guttural
and junior will be needed to determine the depth of the excavation the
depth will vary as per building depending upon soil strata
excavation should be carried out as per the drawings defined lengths
and widths excavation is to be done by the JCB.
Excavation is the process of removing earth to form a cavity in the ground in
the construction industry.
Excavation
can be done manually on small sites or in confined spaces using tools like
picks, shovels, and wheelbarrows. Larger-scale excavation will necessitate the
use of heavy machinery such as bulldozers and backactors. See Excavating plant
for more information.
Types
of Material
The
material being excavated is a common method of classification:
Excavation
of topsoil
This
entails removing the exposed layer of the earth's surface, including any
vegetation or decaying matter that could compress the soil and render it
unsuitable for bearing structural loads. The depth varies depending on the
site, but it is usually between 150 and 300 mm.
Excavation
of the earth
This
entails removing the soil layer directly beneath the topsoil. The removed
material is frequently stockpiled and used to build embankments and
foundations.
Excavation
of rocks
This
is the excavation of material that cannot be excavated without the use of
special excavation methods such as drilling (by hand or with heavy machinery)
or explosive blasting.
Removing
muck
This
is the removal of excessively wet material and soil that cannot be stockpiled.
Unclassified
Excavation
This
is the removal of a mixture of the materials listed above, such as when it is
difficult to distinguish between them.
Excavation
goal
Excavation
can also be classified based on the work's purpose:
Excavation
by cut and fill
This
is the excavation process in which the material that is cut or stripped is
removed. The removed topsoil and earth can be used to fill embankments,
elevated sections, and other structures. It can also be used to create a level
surface on which to build by 'cutting' and moving elevated sections of the site
to 'fill' lower sections of the site.
Excavation
of trenches
A
trench is an excavation where the length greatly outnumbers the depth. Shallow
trenches are typically less than 6 m deep, while deep trenches are greater than
6 m deep.
Trench
or footing excavation is commonly used to create strip foundations, buried services,
and other structures. The technique and plant used to excavate, support, and
backfill the trench are determined by factors such as the trench's purpose,
ground conditions, trench location, number of obstructions, and so on.
The
following are some of the most common techniques:
·
Full
depth, full length: Suitable for long, narrow, shallow-depth trenches such as
pipelines and sewers.
·
Full
depth, successive stages: Suitable for deep trenches where work can be done in
stages to reduce the risk of collapse.
·
Stage
depth, successive stages: Suitable for very deep trenches in confined spaces,
as well as deep foundations and underpinning.
Excavation
of the basement
A
basement is a portion of a building that is partially or entirely below ground
level.
Over
Excavation
Excavation
that extends beyond the required depth for the formation of a below-ground
structure due to the presence of unsuitable material that must be removed.
Excavation
of a road
This
usually entails topsoil removal and cut-and-fill. See Road Construction for
more information. excavation of a bridge This typically entails the removal of
material for bridge footings and abutments. The work can be divided into three
categories: wet, dry, and rock excavation. Underwater excavations may
necessitate the use of specialised drill and blast techniques.
Dredging
Dredging
is the process of excavating and removing sediments and debris from beneath the
water's surface, typically from the bottoms of lakes, rivers, and harbours.
PCC
After
the excavation the surface is leveled PCC poured over leveled
surface Foundation shuttering shuttering arrangement for foundation
is to be made once PCC is done shuttering for foundation is placed it
should be strong enough to withstand all types of dead and live
loads foundation bars foundation bars shall be laid on
the surface main bars and distribution bars shall place as per
drying column bars.
made
four column bars with links as per drawings alum steel and foundation
steel to be tied properly to avoid joint cracks reinforcements shall
be as per bar bending schedule prepared according to drying the
reinforcement shifting and binding shall be started as soon as
shuttering is completed reinforcement bindings shall
continue with shuttering work as progresses concrete work and foundation
a foundation is a poured concrete pathway that is used to spread the
weight of the building from the foundation to the soil
it
is very necessary to check the levels of foundation before concrete
work depth of foundation varies from 1.5 to 2 meters shuttering
removal the foreign work removal procedures should be supervised by
the engineer to ensure that quality of hardened concrete and
structural member that is it should be free from on has minimum
casting defects such as honeycombing size on shape defects etc these
defects and concrete influence the strength and stability of structure
thus immediate repair works can be done or the members can be
rejected backfilling once the foundation is completed backfilled
the remaining excavated area.
Around
foundation with soil backfill provides stability to the building
a euro trade Magas foundation beam reinforcement shall be as per
drawings top bars bottom bars and stirrups to be placed with proper
development length joints and the beams shuttering should be tight
against leakage of cement grout construction of shuttering should
permit removal of various parts and desired sequences without damage
to the concrete beam concreting beam is poured with concrete with
great mentioned in the drawings the positioning of reinforcement should be
properly aligned shuttering parts and connections should be arranged in a way
that makes foreign work removal easy and simple prevents damage to concrete and
formwork panels so that it can be reused without extensive repair slap
concreting great slab requires no
reinforcement
is its resting on ground strata itself top of plinth beams and great slabs
should be at the same level column shuttering columns shuttering should be
rigidly constructed and efficiently propped embraced both horizontally and
vertically so as to retain its shape the shuttering should be said accurately
to the desired line and levels should have plain surface column concreting
after the concreting of footing is complete immediately in a day or two
starters for column should be casted with proper alignment columns of very
important members in RCC design wrong placing of column may affect the overall
behavior of structure concreting of RCC columns should start from the center of
vertical bars and go towards the ends during removal shuttering should not be removed
until the concrete has developed sufficiently strength to support all loads
placed upon it the separation of forms should not be done by forcing it may
damage the hardened concrete beam reinforcement beam reinforcement shall be as
per drawings slab reinforcement slab reinforcement shall be as per drawings
main bars and distribution bars shall be placed as per design slab
reinforcement should be properly anchored with beam bars slab shuttering beam
bottom is first laid on the column and then slapped shuttering his late beam
and slab levels should be maintained as per drying slap concreting after the
concreting of column beam and slab concreting shall start monolithically the
top of floor beam and slab shall be maintained as per levels slab shuttering
removal special attention is required for shuttering removal of flexible
members such as beams and slabs as these members are subjected to self-load as
well as life Lord even during construction they may deflect if the strength
gained is not sufficient to handle two loads shuttering should not be removed
until the concrete has developed sufficiently hardness.
