13. PILE AND PILE CAP
PILE
A pile is basically a long cylinder of a strong material such as concrete that is
pushed into the ground to act as a steady support for structures built on top of
it.Pile foundations are used in the following situations: When there is a layer of
weak soil at the surface. This layer cannot support the weight of the structure, so
the loads of the structure have to bypass this layer and be transferred to the layer
of stronger soil or rock that is below the weak layer. When a structure has very
heavy, concentrated loads, such as in a high rise buildings, bridge, or water tank
pile foundation are used. Pile foundations are capable of taking higher loads than
spread footings.
PILE CAP
A pile cap is a thick concrete mat that rests on concrete that have been driven into
soft or unstable ground to provide a suitable stable foundation. It usually forms
part of the foundation of a building, typically a multi-story building, structure or
support base for heavy equipment. The cast concrete pile cap distributes the load
of the building into the piles.

16. PIER AND PIER CAP
PIER
A pier is a raised structure typically supported by
well-spaced piles or pillars. Bridges, buildings, and
walkways may all be supported by piers.
PIER CAP
The upper or bearing part of a bridge pier; usually
made of concrete or hard stone; designed to
distribute concentrated loads evenly over the area of
the pier.

18. PIER AND PIER CAP

19. ABUTMENT
Abutment refers to the substructure at the ends of a
bridge span or dam whereon the structure's
superstructure rests or contacts. Single-span bridges
have abutments at each end which provide vertical and
lateral support for the bridge, as well as acting as
retaining walls to resist lateral movement of the
earthen fill of the bridge approach. Multi-span bridges
require piers to support ends of spans unsupported by
abutments.

20. ABUTMENT

21. PEDESTAL
A concrete pedestal is a compression element provided to
carry the loads from supported elements like columns,
statues etc. It is generally provided below the metal
columns. In general pedestal width is greater than its
height.
The main functions of pedestal provision are as follows.
To avoid contact between soil and metal elements.
To offer support for elements at some elevation
To allow thinner foundation footing.

22. PEDESTAL

23. BEARING
A bridge bearing is a component of a bridge which typically
provides a resting surface between bridge piers and the bridge
deck. The purpose of a bearing is to allow controlled movement
and thereby reduce the stresses involved. Movement could be
thermal expansion or contraction, or movement from other sources
such as seismic activity.
There are several different types of bridge bearings which are used
depending on a number of different factors including the bridge
span. The oldest form of bridge bearing is simply two plates resting
on top of each other. A common form of modern bridge bearing is
the elastomeric bridge bearing. Another type of bridge bearing is
the mechanical bridge bearing.
There are several types of mechanical bridge bearing, such as the
pinned bearing, which in turn includes specific types such as the
rocker bearing, and the roller bearing. Another type of mechanical
bearing is the fixed bearing, which allows rotation, but not other
forms of movement.

24. BEARING

25. SEISMIC STOPPER
Seismic stopper are mainly based on the concept of
vibration control device (VCD) with capability of
giving stable stage to the bridge and mainly it
absorbs the vibrations and prevent the collapse of
the structure.
Despite the fact that the stoppers, which restrain the
transverse seismic movements of the deck, are
frequently used in seismically isolated bridge, the use
of longitudinal stopper is relatively rare, mainly due
to the large in-service constraint movements of
bridges.

26. GIRDER
A girder is a support beam used in construction. It is
the main horizontal support of a structure which
supports smaller beams.
Girders often have an I-beam cross section
composed of two load-bearing flanges separated by
a stabilizing web, but may also have a Box shape,Z-
shape, or other forms. A girder is commonly used to
build bridges.

27. I-GIRDER

28. BOX GIRDER

30. DECK
A deck is the surface of a bridge. A structural element
of its superstructure, it may be constructed of
concrete, steel, open grating, or wood. Sometimes the
deck is covered a railroad bed and track, asphalt
concrete, or other form of pavement for ease of
vehicle crossing. A concrete deck may be an integral
part of the bridge structure (T-beam or double tee
structure) or it may be supported with I-beams or steel
girders.

31. CRASH BARRIER
Crash/Traffic barriers keep vehicles within their
roadway and prevent them from colliding with
dangerous obstacles such as boulders, sign supports,
trees, bridge abutments, buildings, walls, and large
storm drains, or from traversing steep (non-
recoverable) slopes or entering deep water. They are
also installed within medians of divided highways to
prevent errant vehicles from entering the opposing
carriageway of traffic and help to reduce head-on
collisions.

32. EXPANSION JOINT
An expansion joint or movement joint is an assembly
designed to safely absorb the temperature-induced
expansion and contraction of construction materials,
to absorb vibration, to hold parts together, or to
allow movement due to ground settlement or
earthquakes. They are commonly found between
sections of buildings, bridges, sidewalks, railway
tracks, piping systems, ships, and other structures.

39. CASTING YARD
A casting yard is a confined place where all the concrete structures like segments,
I-girders/ beams etc are casted. The casting yard brings factory-controlled
production techniques, efficiency, quality control, and time savings to bridge
construction. Fabricating bridge segments in a separate area also removes casting
operations from the construction critical path and reduces overall construction
time.
Regardless of the project location or size, a contractor's casting yard for bridge
segments has several essential features.
These include:
-delivery and storage areas,
-a concrete batch plant,
-a rebar cage assembly area,
-one or more casting cells,
-steam curing facilities,
-geometric control stations, and
-segment storage and handling facilities.

41. BATCHING 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.

48. CONCLUSION
In conclusion, the training that I had already gone through is very interesting,
instructive and somehow challenging for someone that has zero-working
experience. It gave me lots of benefit and positive changes that enable me to
enter the working environment. Through this training I was able to gain new
insights and more comprehensive understanding about the real working
condition and practice.
The training has provided me the opportunities to develop and improve my
soft and functional skills. All of this valuable experience knowledge that I have
gained were not only acquired through the direct involvement in task given
but also through other aspect of the training such as work observation,
interaction with the staffs and local people.
From what I have undergone, I am hundred percent agree that the training
program have achieve its primary objective. It is the platform to prepare for
the students to face to real working life. As a result of the program, I am more
confident to enter the working world and build my future career.
