In the first place, we actually scavenge what

we could get from the construction trash.

We ended up collecting timbers and nipah.

All the timbers we collected are actually

still in good condition. Therefore we decided

to design something that has easy access

into it and a comfortable space in it.

Besides that, we also want the space inside

the structure to be ventilated so that it is

comfortable to stay in. Therefore, we

started with a cubical and started to

manipulate with the form. Through the

process of designing this shelter, we were

also inspired by the malay traditional house

as we also collected some nipah for roofing

purpose. Therefore, we decided to create a

slant at the back of the shelter, which

allows us to lay the nipah on it. Initially,

we taught of leaving the sides of the

structure empty, but in the end covering it

up with wire mesh. This is to create a

boundary and ventilate the space within in

the same time. In the process of

constructing the shelter, our design was

improving better and better, as what we

designed on the paper was based on

theories.

Introduction

In this project, we are required to design and build a shelter which can support the weight of a 60kg or heavier person for a s long as possible. Besides that, external forces such as wind and

rain are in consideration also. Accurate structural joints and skeletal structure based on the selected materials are to show in the construction of the shelter. Load bearing and non-load bearing

structures are identified before the construction in order for the load to transfer effectively.

Skeletal Construction Design

The material for our skeletal construction is timber. Besides that, we also used wire mesh for the envelope and nipah for the roof. We decided to use bolts and nuts for the timber joints. We

also used halved joints for the timber bracing.

1. Removing the nails and cutting the timber that was collected from the garbage

dump into designated dimension.

4. Setting up the whole structure by using bolts and nuts and screws.

5. Cut the board into designated dimension for platform purpose and

the wire mesh to act as the skin of the skeletal structure.

2. Sanding the surface of the timber to create a smooth surface.

Construction Process

Page 5: Building Construction 2 Report

1. Setting up the main structures for

our shelter. Joining the timbers

together by using bolts and nuts.

Timbers are already being cut into

our designated dimensions.

3. Drilling holes on the timber to insert bolts and nuts.

6. Folding the nipah leaves to put on top of the roof.

Construction Steps

2. Fixing the horizontal structures for

the shelter by using timber. L-

Brackets are being used to join the

timbers together as using bolts and

nuts are not appropriate in this

manner.

3. Fixing the bracing on the

structure. This is to reinforce the

structure and preventing it from

moving left and right. Screws are

being used to fix the bracing on the

structure. Halve join is created in the

middle part of the bracing to join

both braces together.

4. Fixing the wood pallet that we

collected on the shelter acting as the

structure for the roof of the shelter.

Brackets, bolts and nuts are being

used to fix the wood pallet on the

structure. After that, plastic panels

are being installed on the wood pallet

for roofing purpose. The plastic panel

is being placed against the direction

of the wood pallet as this is the

proper way of installing roof panels.

Due to the lack of material, we

installed the plastic panel

horizontally, knowing that it should

be installed vertically to allow the

water to flow through.

Testing

Distribution of dead load towards the ground

In this test, a person weighted 60kg is required to sit inside the shelter in order to test

the strength of the shelter. The result shows that our shelter is capable of holding a

person’s weight. Besides that, we also tested our shelter of holding two person’s weight

in order to see how much weight that can our shelter take. It is also a success. With the

strength and the material of our shelter, we then assume that our shelter is able to

carry up to 200kg-300kg. During the testing day, it just happens to rain after our

presentation. Therefore, we decide to try whether our roofing structure is working or

not. We moved our shelter under the rain and had a group member of us to sit in the

shelter. The result was outstanding; our roofing structure is a success. The nipah and

plastic sheet roofing with insulating layer is able to hold off the rain water from slipping

through. With the joints that we used in this structure, it allows us to dismantle and

reassemble the structure easily. Therefore, it is convenience to carry the structure

around.

Conclusion Overall, we have successfully demonstrated our understanding on the skeletal construction by creating a strong, weather proof and aesthetically beautiful shelter. Besides that, we also learned

a lot of useful lessons in the process of making the shelter. For example, we learned how to use the drilling machine located in the workshop. Mr.fendi also provided us some practical

knowledge in this shelter making process. This is important for a future architect as the competitive market of construction industry will require the architect to understand even more

engineering knowledge besides design knowledge. This is to lead the team in a better way and to produce a more desirable outcome in a project. It is also important for architects to produce

something that is more sustainable rather than just about designs. Therefore, as an architect student, we must be all around to create sustainable designs. Just as the idiom said, architects

are jack of all trades but master of none.
