How do we build it?
First, we start of with the base. We decided to use the mat footing, as it deemed appropriate for this situation, as it is not implanted into the ground like an actual building.
The support beams that will go into the base and columns. It is basically rolled up paper.
The reinforcements that is currently laid out, but sadly we arranged it wrongly, as there should be spacing for the column support to be inserted.
We laid them out correctly this time in a 4 x 4 formation, the column support will be inserted into the spaces that is present on four edges.
First the reinforcements are dug into the ground by spacing it between the holes in the image above
We wrapped plasticine around it after that to create the columns.
The process is repeated and all four columns are completed.
The finished footing with columns.
Next, we started making the support beams that would go on top of the columns and for the slab to rest on
Look how cute it is
As we can see, the reinforcements are placed rather low of the support beams, because we learned in class that in real life, the base of concrete is subject to tension when load is applied, while the top will be affected by compression. Hence it is important to add support at the bottom of the concrete beam to prevent it from breaking. The same concept is applied here.
When we finished laying it all out in a rectangle shape, we realized that the support reinforcements is too short. We lengthen it a bit so it overlaps each other. Sadly, we forgot to take a picture of the new structure. So what it looks like on the inside now is that the support beams are placed overlapping each other and placed next to the holes where the column support would go in. The overlapping of reinforcements ensure that the beam doesn't break under strenuous loads.
The support beam is added into the holes of the columns and it fits perfectly. As we can see from the bottom angle, the reinforcements is placed quite low in the beam. We have not covered it yet, this is just for testing purposes.
The top view of the structure for now.
The final part is the slab, which will sit on top directly of the structure.
Before placing on the slab
We finally covered up the bottom of the support beam to prevent exposure of the reinforcements. This is the same as in real life to prevent rusting of the internal steel support beams.
The completed model.
Personal conclusion
There was a lot of trial and error that happened during the making of the model. We made many mistakes but we managed to rectify them in the end. We were quite sad that our first model didn't fget approve and had to redo after that. But in the end the revised edition of the model was made following the correct steps, and we now fully understand the sequence of construction of how an actual building will actually be made.
