Reader's Respond Draft 2

In the article “3D building models help bring sustainability into construction”, Jenkins (2015) claims that Building Information Modelling (BIM) has adverse possibilities in replacing traditional 2D drawings. BIM creates a three-dimensional (3D) model of the actual building and runs computer stimulation that is capable of countering imminent errors and calculations before the construction of building which minimizes construction defects and reduces building cost. This is supported by Ian Sutton (as quoted from Jenkins,2015),“These innovations are also giving us access to automatically calculated design data before a building is physically built, so we can take a more sustainable approach to the construction of buildings”. BIM has become an essential design tool due to the demand of more complex building and the emphasize of reducing building’s environmental impact by improving energy efficiency and reducing waste.  However, despite BIM being identified globally as a cost-efficient and co-ordinated way of building construction, it is still not globally used.

One reason was due to the cost of implementation. According to an article, "Traditional design versus BIM based design,” Czmoch (2014) claims that the primary problem of replacing traditional design to BIM is due to the high cost of both software and hardware prices. Integration of BIM in a company, requires a huge amount of capital. A single workstation can cost up to a few thousands and can be easily summed up to hundreds of thousands if the company improvises the implementation. In addition, due to the advance technology of the BIM and the increase demand in complex designs in modern building design, it is essential for employers to invest in regular BIM training by professionals to increase the proficiency of design team. This is supported by an article "Traditional design versus BIM based design", Czmoch (2014) which the author claims that designers ignorance to the designing tool will result to a great loss in productivity. Therefore, many small to medium companies have to consider their financial capability before investing BIM into their companies due to the large sum of money that is needed.

Another reason was due to the preference of traditional work. In an article,” A construction revolution,” Chew (2013) states that BIM adopts integrated design approach which brings the team of engineers, contractors, architects and stakeholders together in the initial phase of the project, and connect them through the 3D modeling design with stimulation of the design to identify issues and propose improvements. However, BIM projects face difficulty in bringing the team together due to the lack of collaboration within parties and the preference of traditional work concepts over BIM’s collaborative approach. Traditional work concepts resemble a linear work flow, where individual passes their work down the line with minimal coordination amongst each other. In contrary, BIM adopts integrated design approach, where it ensures all parties work together from the start of the project which can be more efficient and most importantly reducing the need of changes in the later stage. However, experienced parties would prefer traditional work concepts over integrated design approach, due to the unwillingness of sharing important data.
In conclusion, BIM has the possibility of replacing traditional 2D drawings with its advance technology and capabilities. However, for BIM to be globally used, the cost of the software must be adjusted to suit the capabilities for small to medium companies. In addition, the biggest challenge is overcoming the use traditional concepts over collaborative approach, perhaps a detailed research could be done to seek ways in overcoming the issue. Hopefully, BIM will replace the traditional 2D drawings, bringing the technology to a greater height.

Critical Reflection

One of the goals I have set for myself in this module is to improve my oral presentation skills by overcoming my fear to speak in front of a huge crowd. Due to the lack of practice, I lost the opportunity to present my best and smoothly delivery the content I had intended to. A good presentation requires constant effort to practice. However, I was held up with other assignments and projects which left minimal time for me to work on my presentation. The project’s oral presentation was a total disappointment as I was unable to conquer my fear of presenting in front of a crowd. I was too nervous to articulate my ideas smoothly, thus I mumbled through the presentation. After this experience, I realized the importance of maintaining a good posture and eye contact with the audience to keep the audience engaged. The use of visual aid should also be reduced to minimal to avoid confusion between my presentation and the content in it. Most importantly, I feel that despite not being able...

Edited Methodology

7.1. Primary research Our team conducted an online survey to gather the statistics of students and staff members of SIT Dover campus who encounter difficulty finding seats in the canteen they frequent. In addition, the team consulted various canteen store vendors on the feasibility of the application. Primary research was done in hope that the application will benefit both the patrons of the school canteens and the vendors. 7.2. Secondary research Internet research were conducted to identify articles or sources that will bring credibility to the report. Thereafter, the gathered information was analyzed and applied to the proposal. All secondary research can be found in the References and Appendices section.

Analytical Reflection on Oral Presentation

Oral presentation has always been a challenge as nervousness has always been a major problem for me whenever I am speaking in front of a crowd. Hence, before the actual presentation, I had several practices with my team members beforehand to overcome my problem. During the rehearsals, I felt that I was able to articulate my ideas and speak fluently in front of my team members. Unfortunately, nervousness took over me during the actual presentation, which resulted in me leaving out crucial contents. Thus, I received many negative feedback, one of which I was told that my presentation was not in line with my report and my ideas were not delivered smoothly. However, I was complimented for engaging the audience as well as maintaining a good posture during the presentation. With the experience and feedback, I realized to improve my presentation I will have to overcome my fear of speaking in front of a huge crowd. This can be solved with practices and experiences gained over time and...
