Introduction
In this assignment, we were required to produce a report on construction site
visit on the 21st of November 2014 for 3 subjects which are Measurement 1,
Construction Technology and Building Materials. The construction visit was held on 21st
of November 2014 and it was organised by our lecturers.
Objective of the assignment
Understand the basics of the construction process.
Understand the practical aspect of construction techniques in comparison to the
theory aspect in books and its application on site.
Provide real life experience for students have a better understanding and clear
images of what we studying.
Exposure to actual working environment on site including uncertainty
circumstances, for example weather.
Ability to communicate with the construction team members on site and to see
the importance of teamwork in the building team.
Witness the usage of construction equipment on site including mechanical plants.
Explore and identify various types of building materials and technology on site.

Observation on site
On 21st of November 2014 (Friday), our class was separate into two groups visit
to side in the difference time. I was assign in group 2, start at 10am. The site we choose
was near to Taylor’s university. In the morning, we gather in the main entrance of the
site. The officer of the site welcomes us, give us some safety brief. We were told that we
have to wear our safety helmet to avoid injury.

According to the officer, this project is built two blocks with 27 floors of Soho
and 28 floors apartment service. The above includes 4 floor stage and 3 floor basement.
The officer bring us into the site area, this the first time I go into a construction area.
When we go in, the officer brings us to their temporary office. It is build by timber.
Outside the office there is a white board, it actually list down their daily work progress
and schedule. Beside that, the officer also introduces his teammate, other worker to us.

Next, the officer leads us to the inner part of the building. The place was empty,
what we can see is only walls and column. The officer told us there are using flat slab for
this building. Construction of flat slabs is one of the quickest methods available. Lead
times are very short as this is one of the most common forms of construction and flat
slab is able to stand heavy load form the above level. The officer was patient and
explains clearly to us. After that, the officer shows us the formwork they using to build
their walls and columns. The formwork is made by timber and steel. It is place
horizontally on the floor. When they want to use it, they will carry the formwork and
place it vertically pours in concrete to build the wall. The reason of using timber and
steel formworks is because it is durable and strong. Timber and steel are common
materials we will use in the site, the cost for timber and steel is cheap and it is reusable
which able to reduce their cost for this project. However, the officer told us there are
also disadvantages, this formwork cannot be use for a long period. The time consuming

will take longer if there is a larger structure. Beside that, if timber is dry, it will absorb
the moisture from the concrete hence it will reduce the strength of the concrete.
This site is using 2type of formwork, one is engineered formwork system and
other one is traditional timber formwork. Engineered Formwork System is a formwork
which is prefabricated modules with metal frame and covered on the application side.
The advantage of this formwork is able to reduce the time to assemble. Engineered
formwork system is strong and durable. It can use for a long time which able to lower
the cost of construction. By using this formwork, it can produce better and smoother
concrete compare with other formwork. This are the reasons why the officer choosing
this formwork. However, this formwork is expensive and need someone skillful to
handle it. For traditional timber formwork, it is a basic type of formwork which used in
many constructions. Generally traditional timber formwork is use for small amount of
concrete pouring in small construction. The advantages of this system are the price is
low which can reduce the costing and it is easy to handle, does no required skillful
workers because it is the basic formwork. However, the quality of concrete produced is
not better than engineered formwork system and the formwork cannot use for a llong
period.

Next, we saw there is a lot of scaffolding in the side. There are using
independent scaffolding. The function of independent scaffolding is a temporary
structure allows person access to a place in order to carry out building operation. It is
also a working platform to do wall construction. The officer told us the reason why they
choose independent scaffold is because it is easier to build compare to dependent
scaffold. It can save time and independent scaffold is able to move to other places. For
dependent scaffold, it actually fixed on the window and not able to move to another
place easily and reuse. Dependent scaffold is also safer compare to dependent
scaffolding. It has four base plates on the floor, which form a square or rectangle to
provide a better support on the ground.

The officer also told us this building is using grade 40 concrete. Grade 40
concrete is a common grade for every construction. The grade of concrete is basically
the strength of the concrete. Grade 40 concrete is considers as a high strength concrete,
it is strong and able to stand heavy load. However, it is more expensive compare to
lower grade of concrete. It actually has increase the total cost for the building. The
officer said when we choose the grade of concrete, we have to think for several aspects
for example the structure of the building, the reinforcements bar and also the cost of
the concrete. It is possible to have two difference grade of concrete in the one building.
One of the projects he has is using concrete grade 35 for the column and grade 40 for
wall. It can be a request from the employer also. “When a good concrete and a good
reinforcement bar was used, the perfect match will produce strongest strength for the
wall or column” the officer said. It is important to choose the concrete grade match with
the reinforcement bar. If we have to suggest another grade of concrete, I will suggest
grade 30. The reason why there are using grade 40 concrete is to prevent the over
design of engineer and architecture. Actually grade 30 concrete is good enough for this
building structure. After that, we are able to walk around the site and take photo of the
surrounding. We saw there is a lot of building materials place at the side, walls and
columns without finishing. It was totally difference from what we study in the book. It
actually give us a clear images of what we studying and real life experience. We are able
to ask question freely to the officer.

When we finish visit the inner part of building, the officer bring us to the outdoor.
It was really a mess. We saw a lot of steel bars, reinforcement bars and other materials
place beside the road. All the materials they use to build the building were there. We
also saw few heavy machines there. It is to use to carry the material to the top of the
building. Unfortunately we are not able to visit other floor because it is too dangerous
for us. The officer explains each of the material to use the function and detail of the
material for example the length and diameter of the bar. By the way he explains, we can
know that he is very experience officer. We are allowed to take photo of the materials
of the material and surrounding. Beside that, we saw some workers were bending the
steel bars using the bending machine. By using the bending machine, they are able to
bend it to the shape they want. After that, we finish our site visit.

Learning outcome / Conclusion
In the site visit, I enjoyed myself and gained a lot of experience and knowledge.
This site visit gave us a real life experience, what we cannot see in the book. It actually
gave us a better understanding and let us know how a construction is progress. This visit
also gave a opportunity to approach the site worker an also officer. We able to gain
more real life experience from the workers. Throughout this activity, we have a clearer
vision of what we going to do in the future and the challenges we will face. It actually is
a good preparation for us.
In a construction area, safety is the main issue we concern about. When we
enter a construction area, we should follow the safety step. We have to wear helmet,
proper shoe and uniform. All these are to avoid injury and to protect ourselves. We
should be alert in the construction area, more careful to prevent hurt. Evert activity we
carry in the site should follow the safety guide.
Next, this site visit gave us a clearer image of what we will do in the future. It is a
good preparation for us. Through this real life experience, we have a better
understanding of the building structures for example beam, column, slab, wall and so on.
It actually helps us to give better answers in the exam and out study.
While walked around the side, we saw how worker bending the steel bar, doing
formwork and so on. All this work required a lot of knowledge and skills to carry out. It
might look easy but it is not. We also saw a lot of building materials and machines at the
side, is actually look the same. Without knowledge we are not able to differentiate
those materials and its functions. Hence we should pay more attention in out lecturer
class and study hard for our future.
