On the fourth day it was starting to get very busy.
The early morning we started on focusing on the model making. One of our members wasn’t able to make it to the session so we were down on man power to create the model.
What I did for the day was do some parts of the modelling such as crafting the parts of the bridge so we can easily assemble it the next day. I was also helping on making the poster so I’m basically split into doing two things at once.
I mostly contributed by doing the hand sketches and illustrations for the poster. The poster was left to the trusted hands on one of my group members and they did mostly the writing and presentation. 
After the day I went home to do some extra work on the model so it’s ready for tomorrow for assembly. The model floor is made out of foam board, the supports is made out of wooden dowels stuck together by hot glue from the glue gun, the metal railings is made out of staples pinned to the foam and the walls is made out of thin plastic.
I assembled most of the parts in the evening and all that was needed left was the supports and the Base of the model to be ready.
Not much difficulty happened but alot of work needs to be done so I need to handle some stuff that are needed at home for the next day.
