Technical report draft 1

Background Information

When waiting for the train, passengers tend to crowd around the doors near the escalator and not move toward the ends of the platform. This causes an uneven distribution of passengers across the carriages of the train when they board, resulting in carriages at both ends of the MRT being relatively empty compared to the carriages nearer to the escalators.


To demonstrate our point, our team went down to Clementi MRT station on a weekday evening, right before peak hour and recorded our observations. We positioned each team member at three consecutive carriages. Carriage number four was nearest to the escalators and the elevator while carriage 2 was the furthest.




Each member would count the total number of passengers waiting to board a specific carriage. For more pictures please refer to the appendices.

Based on our observations we can tell that there is a direct correlation between the number of passengers boarding a carriage and that carriage’s proximity to the escalators/elevators. This is because passengers tend to cluster at the carriages near the escalator. Making some carriages more packed than others which will result in an uncomfortable commute for some of the commuters.


SMRT has also been placing staff during the peak hours to usher commuters to emptier parts of the platform. This solution is labour intensive and passengers may not be aware that heading to an emptier part of the platform can result in a more comfortable and less crowded commute.


By implementing our solution, SMRT will stand to gain directly from it. Them being the owner of the MRT, will be able to create a more comfortable experience for their commuters. Also, with our solution, commuters will get to have a more comfortable commute experience, as they will now be made aware of how crowded the carriage is. With the information they have, they will be able to spread themselves evenly throughout the carriages, leading to a more comfortable commute for themselves and others.


Overall, it will help to evenly distribute the number of commuters in each carriage, which also increases the overall efficiency of the train. Also, by evenly distributing the commuters, it will ensure a more comfortable commute for the commuters.

Problem Statement

In order for Singapore’s MRT system to maximise passenger capacity while maintaining a lower passenger density. Commuters should enter carriages with the most available space, resulting in an even spread of passengers across the various carriages.


In Singapore’s Mass Rapid Transit (MRT) system, commuters tend to cluster around the carriages near the escalators, causing an uneven distribution of passengers across the train.


By tracking the weight of each individual MRT carriage, approximate passenger density can be calculated. An indicator that flashes red, amber or green depending on the passenger density should be installed above the platform doors to provide this information to commuters so that they can make a more informed decision on which part of the platform to wait.


Purpose Statement


The purpose of this proposal is to recommend SMRT to adopt our solution of tracking passenger density on trains and passing this information to commuters to encourage them to spread across the platform. This is in everyone’s interest as the benefits include reduced manpower needs for SMRT and a better ride experience for commuters.


Proposed Solution


The proposed solution is to gather information about the carriage’s weight to estimate approximate passenger density. Passengers will then be able to tell if a carriage is full or not before the train arrives at the platform by means of a simple coloured lights indication system installed along the platform.


The weight of a carriage can be determined with existing weight sensors in carriage suspension systems. Professor Zhou from the Singapore Institute of Technology remarked that the existing sensors may not currently be accessible. This is due to the manufacturers of the train restricting the access of such data from the sensor as there has not been a need for it.  The weight of individual carriages is logged once the door of the carriages has closed. This information will be used to calculate approximate passenger density. The approximate passenger density will then be passed to the next station either by making use of existing signalling/communication systems or by computing it before the train leaves the station and relaying it over the internet to the next station.

As for the implementation of indicators above the platform, our proposal is to install a LED indicator that changes colour from red to amber to green depending on the density of the incoming MRT. Red indicates that the density of the carriage is high. This means that it is crowded and you might have to wait for the next train or look for another carriage that is less crowded. Oranges indicate that the carriage is mildly crowded while green indicates that it is relatively empty.

Reader response draft 3

In the article “3D building models help bring sustainability into construction”, Jenkins (2015) claims that Building information modelling (BIM) is capable of replacing traditional 2D drawings with advanced digital technology. It mentions that BIM constructs a 3D model of the actual building and has the capability of running computer simulation, reducing the cost of construction and increase the energy efficiency of a building. However, Jenkins, claims that with BIM’s advanced technology it is still not commonly used. According to Coventry University’s sustainability director, Smithson (as cited in Jenkins, 2015), even though one is able to convince others that BIM is better, it is hard for them to acknowledge its worth until they try it using it for themselves. Which is why Smithson and her team run one out of three immersive simulation centre in the world that has BIM technology to allow them to get a hands-on on BIM to prove its effectiveness.

Even though there are still people who are stubborn and does not want to move on to BIM, it is still important for construction projects.

First of all, BIM is able to reduce the time needed for a company to build a building, which every company would want as time use reduced would mean the cost reduced and allows them to increase their productivity. In the article "The Importance of Building Information Modeling"(n.d.), it mentions that Carnegie-Mellon University research has shown that an improvement of just 3.8% in productivity would be able to pay for the construction and sustainability of the building. In the same article, the author also says that BIM able to reduce the time needed for cross-referencing and approval during the building phase.

Secondly, BIM provides an important feature which is to allow members of the group to provide information to each other accurately and fast. As sustainable building project becomes more and more complex, it is essential that the members of the group provide information to each other accurately. In the article, "Building Information Modeling: How the construction industry is getting 'smart'"(2015), the author mentions that with the traditional way, group members are given individual task and will then be gathered after each individual has done their part. But this will lead to conflicts and problems later in the design process as each individual task will find itself unable to fit in with others. From the same article, the author also mentioned that with BIM, the task will be uploaded to the cloud so that everyone in the group is able to view and edit it. By doing this, time used to fit all the individual task together will be eliminated and thus cut down the time for the whole project.

Lastly, BIM also allows the client to understand what is being presented to them and able to make changes to it when required. As It is important that the client understand what is being presented to them. BIM is able to show clients an accurately built 3D animated model and allows them to make changes to it, Calvert (2012). This goes to show that BIM is more than just a tool used for designing, it can be used to show important information accurately.

In conclusion, BIM is important as it reduces the amount of time and money used, and it increases the productivity. It is not just a software used to draw and virtually build a 3D model, it is also able to use in other areas like accurate cloud information sharing, presentation, etc.

Even though there are still people who are stubborn and does not want to move on to BIM, it is important for a construction project to make use of BIM.

First of all, it is actually quite surprising that there are still people who work with the 2D drawing for construction. As 2D drawing does not give designer any leeway as compared to using BIM. Once there is a mistake in the drawing, the designer has to look for the mistake as if looking for a needle in the haystack. If the mistake cannot be found, the whole drawing has to be redrawn and time has been wasted. As compared to BIM, it is able to identify the error and correct it instantly, thus it is not surprising that it is regarded as important for construction.

Secondly, as sustainable building project becomes more and more complex, it is essential that the members of the group provide information to each other accurately. In the article, "Building Information Modeling: How the construction industry is getting 'smart'"(2015), the author mentioned that with the traditional way, group members are given individual task and will then be gathered after each individual has done their part.

By doing this, time used to fit all the individual task together will be eliminated and thus cut down the time for the whole project.

Lastly, When the client is being presented with the product, it is important that the client understand what is being presented to them and able to make changes to it when required. According to the article, "10 points and the benefits of the BIM", Calvert (2012) mentioned that BIM is able to show clients an accurately built 3D animated model and allows them to make changes to it. This goes to show that BIM is more than just a tool used for designing, it can be used to show important information accurately.

In overall, BIM will eventually fully replace the traditional way of doing construction project as nowadays sustainable building is becoming more complex. Without BIM, the time and cost to construct one of those building will be too much.

Formal Letter: Self Introduction

Subject: Self-introduction

Dear Professor Brad, 

My name is Yio Xue Le and I am writing to formally introduce myself to you. I graduated from Nanyang Polytechnic with a diploma in electrical engineering with Eco-design and currently pursuing a bachelor in sustainable infrastructure engineering (land) in Singapore Institute of Technology. During my life in Nanyang Polytechnic, I became more interested in engineering and it is part of the reason why I chose this course.

My weakness in communication is the lack of confidence to speak and unable to express myself clearly. Whenever I am in front of an audience I tend to get nervous and blank out. Even though I practiced many times for my presentation, I am still unable to get used to speaking in front of an audience. In a group discussion, I tend to just listen to others and follow through as I do not have the confidence to speak up.

Gradually, listening to others made me a good listener which became my strength in communication. Listening is part of effective communication as it allows people to understand the meaning behind the words of what others talk about. By listening to others I am able to understand them better and get the work done efficiently and correctly. 

My goals after going through this module are to be able to improve my confidence in speaking and my writing skill. It is not just to get a good grade for the module as it is an important skill that we all need in our daily life.

Thank You

Best regards, 

Yio Xue Le
