Analytical Reflection

Related to the presentation my team led recently, I thought each of the team members were very well prepared. We rehearse for the presentation numerous times to keep it up to standard. Now, I'm going to write a bit more on my part of the presentation, by highlighting the strengths and weaknesses.

For my strength, I think I was well prepared for the presentation. I knew my contents well which allowed me to go straight to the main point on my part of the presentation. The design of the presentation was clear and brief. Since I know my contents perfectly, I didn’t spend much time looking at the screen to see if I was on the correct slide at the right time. The last strength I will enlighten is the clarity of my English. The flow of my presentation was slow. I made pauses in between my presentation to make sure everyone understood what I was trying to present. It is also effective for the audience to analyse and get what I want to present.

My main weakness is giving speeches in front of a big group. However, the Effective Communication module helped me to improve on that. My tone throughout the presentation was rather monotonous. I also felt that there were certain pronunciation problems throughout my presentation. My presentation was missing a sense of humour. Usually, I love making fun and doing some jokes during a presentation. However, this time I was rather serious as it was an issue which was serious. I think I could have smiled more. It’s the essence of a presentation to make the audience comfortable.

All in all, this oral presentation was a valuable experience for me in giving presentation speeches.  I learned many things through the presentation and the whole project in general.

Group Meeting Minutes.

Before the group had decided on a Project Proposal, the team held a meeting to discuss whose idea was the most genuine idea. Here's the meeting minutes:

Team C.I.A

Meeting Minutes

September 29, 2016

I.      Call to order

Chris called to order the regular meeting of Team C.I.A at 1400 on September 29, 2016 at AP-S31C.

II.      Roll call

Abiali conducted a roll call. The following persons were present: Chris, Abiali, Ike

III.      Agenda Rising

a) To discuss topics for the next big project.
b) Deadlines to adhere.

IV.      Discussion

Chris – Chris mentioned on the need for more sustainable buildings due to the massive pollution. Thus, we need to reduce the usage of fossil fuels and have a more environmentally approach such as using windmills to produce electricity. He felt that the team could come out with more ways for sustainable solutions for buildings in Singapore such as solar power or even turbines. It would not only benefit us, but for the future generations. However, all these comes at a heavy price.

Abiali – In the north-south-east-west lines, train announcements are not made in a systematic way. The announcements are not in sync to the location of the train. For an example, when the train leaves station A for station B, the timer of the announcement starts. The timer will continue although the train has stopped in between 2 stations due to unknown events. Thus, the announcements are not accurate and may cause confusion among the commuters. He felt that the team could come out with a sensor to be placed on the track and on trains. When only the sensor on the track senses the sensor on train, the announcement will then start. In this way, the announcement will be more accurate and create lesser confusion among the commuters especially the tourist. However, the implementation of the sensor would be expensive and more manpower would be needed for maintenance needs.

Ike – Modern buildings in Singapore, tanks are placed on buildings to provide water for everyday usage. However, when maintenance/inspection is needed to be done, a partition would be placed in the tank. The partition would close half the water tank which would be needed for maintenance. Thus, only the other half of the water tank would provide water for the residence in the building. As this process is being repeated, the partition will start to deteriorate. Thus, causing water contamination. The team came out with an idea such that it will solve the problem of contamination. The water tank will be split into 2. In this way, when maintenance needs to be done, just close 1 of the water tank. The other water tank will provide water for the residence in the building. This will cause no leakage and contamination. However, by splitting into 2 tanks, more space would be needed in this space constrained land.

Conclusion – In conclusion, the team has decided to choose Ike’s idea as it creates an impact on our everyday life. It will not create any water contamination or disruption to our everyday water usage. Chris idea was good, however, the scale of the idea is too big and also there are too many companies solving this major problem. Abiali idea was good. However, it was a minor issue which does not create a massive impact for commuters on the train.

Summary + Reader Response Draft 4

In the article “Trains on the North-South, East-West lines safe for service”, the Land Transport Authority (LTA, 2016) wrote that despite undergoing rectification works, the trains that have been in the media spotlight are safe for service. According to LTA, all new trains are tested before they are put into service. For the defective trains, immediate action was taken to prevent defects from resurfacing during train operation. Hairline cracks that were discovered during inspection were confirmed to not affect operational safety. Nevertheless, to ensure that there are sufficient trains for commuters, all affected trains were sent back, one at a time, for rectification. Stringent checks would also be performed regularly to ensure operational safety of all trains. However, LTA should have made further investigation, about whether purchasing trains manufactured from CSR Sifang, is the most ideal choice. *

Firstly, the article mentions that ‘these hairline cracks were due to localised impurity in the aluminium car-body material’, however, it fails to mention on the severity of the condition. “As one engineer put it, impurities in aluminium alloy is a catastrophic problem - in any industry. The structure may be sound initially, but its durability will definitely be compromised” (Tan.C, 2016). This proves that the trains may not have been the most ideal choice as the quality standard of the train is lowered due to the impurities in the material found in the train. CSR Sifang trains are the first batch of trains that have experienced this problem. “C151, the predecessor of C151A, has been manufactured by Kawasaki Heavy Industries in Japan since the 1980s. The two models share similar designs, but the C151 has been used by the SMRT since 1987 without experiencing cracks.” (Lai, 2016). Although ‘C151’ trains have been in service for more than 20 years, it has not experienced any cracks. Whereas the ‘C151A’ trains which is manufactured by CSR SIfang has been in service for less than 10 years and has given many problems compared to trains manufactured by Kawasaki. *In this case, CSR Sifang trains are not the ideal choice as the life span of the train is being compromised and the quality of the train is not up to standard.

Moreover, the hairline cracks were not only the major issue caused by C151A trains. “On 17 December 2011, seven SMRT trains stalled on the North South Line causing the worst disruption in the entire SMRT history. The disruption across 12 stations from Marina Bay to Ang Mo Kio station lasted for at least seven hours, affecting at least 94,000 commuters” (Chew, 2015). The main cause of this massive disruption was due to the stalling of the trains which had theCurrent Collector Device (CCD) damaged. As one of the engineer mentions, “the immediate cause of the stalling of the trains was damage to their Current Collector Device (CCD) 'shoes' due to sagging of the 'third rail' which supplies electrical power to the trains”. In this case, due to the poor quality of the CCD, it was not able to send the electricity signal to the train. As the report mentions “During both incidents, sections of the third rail sagged after multiple “claws” which hold up the third rail above the track bed were dislodged”. This has caused a massive disruption that proves that CSR Sifang trains are not the ideal choice of trains for service.

In conclusion, LTA should do their best to stop these incidents from occurring and ensuring a safe journey for its commuters. Although Singapore has ten of the best city train (Gwyn, 2014) network in the world, these are some of the minor/major issues that may lower the standard of quality.

Reply from Tanjong Pagar Town Council.

Dear Ike,

Sincere apology for the delay and our reply as follows:

  1. Do most HDB flats have only one water tank on its rooftop to supply drinking water to residents? If so, do these water tanks have several internal compartments to provide against water supply interruptions?
    Ans: There are 2 or more water storage tanks on roof level in HDB apartment blocks. There is no internal compartment within the tank.
  2. Are there any HDB flats which supply drinking water using more than one tank?
    Ans: Under normal circumstances, drinking water to flats is supplied by all tanks at the block because the storage tanks are interlinked with the control valves.
  3. How often do water disruptions occur annually?
    (Due to shutting off tanks for inspection, cleaning, maintenance etc.)
    Ans: All water storage tanks (lower and upper levels) shall be washed, cleaned and sterilised annually. The Licensed Water Service Plumber shall submit water sample to a approved laboratory by PUB for testing and certification. 
  4. What is the average time taken for each of these water disruptions to be resolved?
    (Restoration of water supply to HDB residents)
    Ans: There is no disruption at all to water supply to residents. To avoid any misunderstanding, it is our practice to notify residents of the work by putting up notice on noticeboard in advance. 
  5. What is the Town Council’s view on expenditure towards water tank upgrading works?
    (Priority level compared to other Town Council projects)
Ans: Town Council is responsible for the routine and cyclical maintenance works of the water storage tanks. Any upgrading work to storage tank will come under the purview of HDB and the relevant authorities.

We hope the information will help your students in the study.

Best regards

Dear Town Council,

I am Ike, a first-year student at the Singapore Institute of Technology, and I am part of a project group that is looking into improving water supply in HDB flats by proposing methods to reduce, if not eliminate, water disruptions affecting residents. As such, we are currently conducting research on the rooftop water storage tanks. As your team is in charge of estate improvement works in the district, we thought it would be best to achieve a better understanding of the water storage and supply situation in HDB flats by drawing upon your team's many years of experience.

Our enquiries are as follows:

  1. Do most HDB flats have only one water tank on its rooftop to supply drinking water to residents? If so, do these water tanks have several internal compartments to provide against water supply interruptions?
  2. Are there any HDB flats which supply drinking water using more than one tank?
  3. How often do water disruptions occur annually?
    (Due to shutting off tanks for inspection, cleaning, maintenance etc.)
  4. What is the average time taken for each of these water disruptions to be resolved?
    (Restoration of water supply to HDB residents)
  5. What is the Town Council’s view on expenditure towards water tank upgrading works?
    (Priority level compared to other Town Council projects)

We would be grateful if you could assist us to answer some of these questions, as this will greatly aid our research. Many thanks and have a great week ahead!

Email sent to PUB regarding The Team Project Proposal.

Dear Mr. Toh,

I am Ike, a first-year student from the Singapore Institute of Technology (SIT). Having been tasked by our lecturer to find a solution for an engineering problem, my project group decided to conduct research on the water storage tanks found on the rooftops of buildings, and we thought it would be best to consult PUB and get a professional opinion.

As some of our questions are technical in nature and others revolve around the current water supply and storage situation in Singapore, we would be grateful if a PUB representative could answer a few of our questions via interview or writing and in doing so help us achieve a better understanding with regards to this subject.

Hence, we seek your kind assistance to redirect our request to the relevant persons, so that we can contact and follow up with them as soon as possible. Thank you very much and have a great week ahead!

Best regards,
Ike Domenden
