Executive Summary
I received industrial training at AIDANINVEST ENGINEERING, Kuala Lumpur, as part of the
curriculum and partially fulfilling the requirement for the Bachelor's degree in Civil and
Environmental Engineering The internship lasted four weeks between June 8 and August 28, 2020.
In the hosting company, the site works with several jacked-in pile machines were designed,
especially on the foundation.
Initially, a survey and site clearance was done whenever a new project was to be conducted. This
was generally done by other companies that were hired by the main contractor and supervised by it.
The company has decided on methodologies and machines to be used in work according to the
examination date. The site also conducted excavation and leveling of the soil. It took time and
permission from the authorization to transport the bottled-in pile machines through trucks and
crawler cranes to the new site. I have accompanied all these works the site supervisors. As the main
task I've done on the site was work, I got many training experiences. During this period, I have
learned how to communicate with employees and how supervisors are in charge of the workers at
work, how to monitor the completed work at the workplace, and how to manage work.
I was also able to apply to practical work the theoretical knowledge that I learned in classes. During the
internship, I had no training in office work. After the construction work and know-how, I could see how
to manage and control work on schedule after the foundation work.

construction are as follows:

Applying acquired expertise in real-life industry exercises. ·

To give students the opportunity, through their field of study interaction with professionals, to
acquire interpersonal knowledge and teamwork skills.

Enhance cooperation with industry and the University and develop collaboration.
Company Introduction
AIDANAINVEST ENGINEERING is the name of the company where I completed my industrial
training. The company did various pile foundation work.
I was given work, especially on the building of the foundation during the training at the company.
Because of some government requirements, particularly for safety, it was not easy to secure a place
for an internship in any construction company. I tried to apply for some construction companies from
the beginning of the industrial training for students who would complete the third-year training this
year, but no one responded with my application; Mr. ANARGUL accepted me for the company. I
was gradually made aware of the importance of all foundation construction work. I have a lot of
experience in building foundations through my industrial training as a civil engineer in this company,
and I would be instrumental in my future career. As I mentioned above, it was difficult for me to get
an academic position in Malaysia. I decided to make the best efforts in the area that I was accepted.
I've been trying to learn the company's techniques. I watched how the workers were being managed.

The company was introduced to the head office in Kuala Lampur on the first day of the internship,
orientation was taken the second day of the Week, and introduction was provided to sites on the third day
of the internship. On the fourth day, I worked in an office on the plans and meetings with the bosses. It
was the weekend for the fifth day and sixth.
Weeks 2 (15 to June 21, 2020):
I work at KaulaLampur on the first and second day of the Week; managers focus on the third. On the
fourth day, I went to Klang, a double-story house finished; I went only to check it. I just estimated the
concrete for the foundation of the house on the 5th day of work. It was the weekend for the sixth and
seventh day.
3rd Week (22nd-28 June 2020)
I work in the proper working and concrete-treatment site for the first time of the Week, and I am in Kuala
Lampur for the second day, where I inform management. On the third day, I am working on the AutoCAD
desktop; on the fourth day, I went again to check the foundation's treatment process. The sixth and seventh
day was the weekend, and I assist in estimating concrete for the poring.
4th Week (June 29 to July 5, 2020)
I work for the first four days on drawings from the office and AutoCAD, helping the elderly finish some
2D drawings and finding out more about drawings from the elderly; on the fifth day, I visited the site
supervised the foundation curing of the concrete. I've been also working on piling the foundation work
from home on the fourth and fifth days. In typical cases, I worked at home to estimate the concrete project
and the foundational design by AutoCAD.

Detailing of the work
Jacked-In Piling System
A few years ago, in Malaysia, the first jack-in piling system was designed. It started with an
alternative to the tedded woodpiles, with a low jacking capacity of 20 tones for small RC piles of 10
tones. The capacity of the jack-in was increased to 60 tones and 90 tones afterward.
In the mid-1990s, consultants and government authorities investigated creating a system of
packaging that could exceed 100 tones. In China, a system of this kind was developed, and the
jacking capacity rose to 400 tones, then to 600 tones. Square concrete, circular, spun concrete stacks
of 250 mm to 550 mm in size, diameter 0.3 m to 0.6 m, stainless steel, and H stack. The installed
piles have a working capacity similar to regular driven piles, ranging from 1000 KN to 2,500 KN if
ground conditions allow (Kou et al., 2018).

Pile capacity
The jack in force for every penetration of 0.3 m (1 ft.) is recorded during pile installation. A "set" is
taken when the jack-in force collects to indicate the bearing stratum is reached. The pile is usually
jacked to maintain 2DL strength. This mechanism is similar to an accelerated static load test
performed on the battery. Stack load tests check the set. Because each stack is installed equally, the
capacity of every stack is checked. In an erratic Siltstone basement, the high jack-in force ensures
good contact between the pile tip and the base. Pile deviation problems and the damage caused by
irregular calcareous surfaces and hard-driving are significantly reduced.
Standard Practices of Jacked-In Pile Installation
The advantage of the jack-in piling procedure is the jack-in strength used to overcome the subsoil's
penetration resistance, compared to the driven pile, which indicates hammer blow numbers only. This can
be like a complete penetration resistance profile similar to a cone penetration test where the final stack
capacity is detected at the end of the stack. The employee records the pressure applied against the pile
penetration.
7
The applied pressure reader is usually placed in the control room of the machine's upper
compartment. In contrast, the operator who records the penetration of the pile is placed underneath
the machine.
As demand for using a jack-in installation stack to support high-rise buildings increases, the stack
manufacturers create a greater structural capacity for concrete piles. The launch of a grade 90
restressed concrete spun pile, and thicker pile reveals that pile manufacturers are innovating and
evolving to meet the market requirement to support higher building loads; however, specific capacity
errors occur, particularly about short end bearing piles with insufficient embedding in the competent
materials, where the capacity of the pile end bearing is developed from and also concerning the proof
of the load insurance at the end of the pile.
Advantages and disadvantages of the jack-in piling system
1. Noise-free, no mud slurry, no excavated stock to be disposed of.
2. Sound quality compared to bored batteries as pre-cast and jack-installed batteries.
3. No hard-driving, no underground casting uncertainty in situ.
4. A lot faster than building bored batteries.
5. Up to two times the loads (DL) or higher is checked for each pile with a jack-in force.
6. There is no question of obstruction of the dump material as stated above. When a battery is pushed
under a 2DL force or higher, it is pushed off the obstacles or pulled up to a stratum or base.
Disadvantages
1. If there is a small rock or thin hard soil layer at the end of the pressure pile, then errors are caused
during the erection process.
2. Because the height of hydraulic jacking systems is approximately 70 tones and the soil is not the same,
this condition will lead to this tool's tilting. The safety of workers would be harmful to this condition.
3. Mobilization of the system in soft areas or muddy regions is challenging.
4. The hydraulic bagging system tool's movement is slow, so it takes a long time to move, particularly at
a relatively long distance from one driving point to the other (Li et al., 2017).
Installation Method
To exert them piles' jacking force, direct compressive contact from the hydraulic jack onto the pile
8
head can also be done using the hydraulic grip or the frictional grip on the pile shaft. The main
difference between the two jacking systems is that the frame length above the piling platform is
above that of the exposed pile for the first direct pile head jack system. In contrast, the jacking frame
may be lower for the later frictional grip because the grip can be at any medium height of the exposed
pile wave.
The gripping system seems to have a better technical advantage from the point of view of pile structural
buckling. Energy releases the potential of a high elastic compressive strain in the pile's body, particularly
for long piles with a high capacity. The hydraulic grip mechanism may require a widened grip zone on
the battery shaft due to its high friction requirements and structurally strengthening the body to take on
the high radial compressive grip force.
Pre-boring methods are a prevalent method to overcome the pile's premature termination when
obstructions to pile penetration are expected. Pre-boring allows the Jack-in stack to pass through obstacles
within the expected end of the stack. The backfill is occasionally carried out in a pre-bored hole to obtain
the lateral stack containment. If the pre-boring hole is not re-filled, there can be severe implications for
the pile performance with the potential stress relaxation of an open gap between the circular pre-boiled
hole and the pile shaft (Liu et al., 2019).
Common piles driving problems and solutions
Pile driving is often a time-effective and cost-effective way to pile up the Earth. But because we
work with the Earth's soil and other hidden features, an unknown element is present, and things are
not always as planned. Whether we drive concrete, steel, or piles of wood, there are many problems.
Not surprisingly, pile driving difficulties are usually linked to adverse or unforeseen conditions in
the soil, leading to piling damage, hammer pile alignments, and other problems.
Blow Count Is Above Pile Penetration Requirements
Soil analysis should accurately predict how many blows are needed to drive a pile to its intended depth
and indicate a problem with the driving system, soil, or the two if the number of blows is much higher
than expected.
Confirm that the pile is driven enough and that the driving system corresponds to the pile type. If the stack
and driving system is adequately matched, check that the driving system's operation complies with the
manufacturer's guidelines.
9
If there are no apparent problems, dynamic measures should be taken to determine whether the problem
relates to the pilot system or the soil behavior. The driving system's problems may include pregnancy,
preadmission, low hammer performance, or an overly soft coil. Potentially increased soil resistance, with
later relaxation (this requires rehabilitation to check), significant soil tremors, or heavy soil damping can
include greater soil strength than anticipated.
Piles Are Driving Out of Alignment
When stacks are moving away from the alignment tolerance, often because of hammer-stack alignment
control issues or soil conditions, suppose a pile door, template, or fixed lead system can improve the
ability to maintain alignment tolerance due to a poor hammer stack alignment control. Soil conditions can
also disturb the alignment, such as nearly-surface obstructions or steep slopes of the base with low
overload (Lorenzo et al., 2018).
Deep Pile Obstructions Are Encountered
Contact the engineer for corrective design if profound obstacles are encountered during driving. Based
on the potential pile damage and soil matrix support characteristics, batteries' ultimate room capacity
hitting obstacles must be decreased. To compensate, additional piles may be required.
Concrete Piles Develop Partial Horizontal Cracks in Easy Driving Cracks in
concrete piles are more common in hard-driving circumstances, but check hammer pile alignment
when they happen during easy driving since bending may cause the problem. The combined
tension and bending may be too high if the alignment appears to be expected.
10
Determine the pile head stress for the blow count observed and compare it to permitting stresses when
damage is done to a concrete pile near the pile's head. Add the battery cushion if the calculated stress is
high. In low calculated stress, lower pile quality, hammer performance, and hammer-pile alignment are
possible causes (Hoang and Matsumoto, 2020).
Head of a Steel or Timber Pile Is Deformed
Some problems can lead to the deformation of the steel stack head or the mushroom of a woodpile. Review
the following:
1. Size and form of a helmet.
2. The power of steel
3. Pile head equality
4. Head of pile of wood banding
Calculate the stress on the battery head if all of these check out. Reduce hammer power (stroke) for low
blow counts when calculated stress is high; a different type of hammer or pile may be required for high
blow counts (Basu et al., 2014).
Conclusion
The internship is a bridge between practical or actual building or civil engineering work and
theoretical knowledge. I want to say that this training represents an excellent opportunity to reach
the ground and know what I had not gained by going directly to work. I am particularly grateful for
this fantastic opportunity for the University, the Faculty of civil Engineering and the Environment,
and the hosting firm.
Industrial training aims to provide an opportunity to identify, monitor, and practice how engineering
11
in the actual industry is applicable. It's not only about gaining technical experience but also about
observing management practices and interacting with local workers. Working with advanced
machines is easy, but not with people. The only way to have this experience for an undergraduate is
through the industrial training period. I think I have the best experience of that. I also learned how
an organization works, the importance of being timely, how highly committed, and the importance
of team spirits. I believe that I have gained a great deal of knowledge and experience in a significant
engineering challenge. Engineering is, after all, a challenge, not a task.
