Reader Response (Final)

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 a building which minimizes construction defects and reduces building cost. This is supported by Sutton (as cited from Jenkins,2015) who mentioned that the innovation of BIM has brought the building industry to a new height due to the innovative approach of calculating design data before the building is physically built. This process significantly shortened the time of construction as well as reducing building materials. 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 due to several reasons.
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-priced software and hardware. Integration of BIM in a company requires a huge amount of capital, a single workstation can cost up to a few thousand and can be easily summed up to hundreds of thousands just for a single design team. In addition, Czmoch (2014) claims that designer’s ignorance to the designing tool will result in a great loss in productivity. Therefore, advance technology of BIM and the demand for more complex designs in the modern building, it is essential for employers to invest in regular BIM classes conducted by professionals to increase the proficiency of design team, which results in an additional cost to the implementation. Despite, BIM’s capability of providing a cost-efficient way of building construction, a substantial amount of capital is required, hence many small-scale companies refused to improvise BIM into their companies.
Another reason why BIM is still not globally used is due to the preference of traditional work approach. In an article,” A construction revolution,” Chew (2013) states that BIM adopts integrated design approach which brings the team of professionals and stakeholders together in the initial phase of the project and connects the team through the 3D modelling design with stimulation of the design to identify issues and propose improvements. However, BIM projects have difficulties 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 workflow, where an 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 reduce the need for changes in the later stage. Despite BIM’s capabilities of providing a coordinated way of building construction, many experienced parties prefer traditional work concepts over integrated design approach, due to the unwillingness of sharing important data.   
BIM has the possibility of replacing traditional 2D drawings with its technology and capabilities. However, for BIM to be used globally, the cost of the software must be adjusted to suit the capabilities small-scale companies. In addition, the biggest challenge lies on the preference of traditional work approach for construction, perhaps simulation workshop could be conducted to help industry professionals to understand the capability of BIM better and hopefully, BIM will be able to replace the traditional 2D drawings in the near future, 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...
