Week 13 Critical Reflection

3.2.1 Module Learning Reflection

At the beginning of this course, I set specific goals for myself to enhance my critical thinking and communication skills. One of the key challenges I aimed to overcome was my lack of confidence in speaking in front of a group of people. Even though I have made efforts to step out of my comfort zone, I often find myself retreating back into it. I hoped that this module would help me become a more confident person and speaker.

Throughout the course, I have made significant strides in improving my communication and critical thinking skills. Engaging in discussions, presentations, and group activities has allowed me to practice speaking in front of others. While I still experience nervousness, I have noticed an improvement in my ability to articulate my thoughts clearly and confidently. However, I acknowledge that my confidence is still a work in progress, and I need to continue pushing myself beyond my comfort zone.

I have participated in class discussion when given the opportunity, sought feedbacks from peers and instructors, and worked on structuring my arguments more effectively. These activities have helped me become more analytical and thoughtful in my responses. Additionally, I have made a conscious effort to practice speaking in smaller group settings to gradually build my confidence.

To further improve my communication skills, I intend to take advantage of more practice opportunities, such as volunteering for leadership positions or joining public speaking clubs, to further boost my confidence in public speaking. I will also focus on developing relaxation techniques to manage anxiety and improve my delivery.

Reflecting on my learning journey, I am pleased with the progress I have made, but I recognize that continuous effort is needed. By consistently stepping out of my comfort zone and refining my skills, I am confident that I will become a more effective and self-assured speaker in the future.


3.2.2 Project Learning Reflection

For the second half of this trimester, we have the opportunity to work in groups of three or four, and ultimately we have to produce a technical report and also an elevator pitch. My group decided to work on the topic on global warming, and how the use of bio-based materials like hempcrete would benefit the world and target audiences. 

Beyond just the technical content, this collaborative project was a worthwhile educational experience as it helped me enhance my collaboration skills. I learned that effective teamwork requires clear communication, adaptability, and a shared vision. Understanding each group member’s strengths allowed us to work more efficiently and respectfully, and I became more aware of how my role contributed to the overall success of the group.

In contrast to individual writing, group writing requires attention to tone and format, and I found myself taking on an editing role, which made me realize I have a strong eye for detail and organization, which will be useful in in both academic and professional contexts. Overall writing a technical report taught me the value of clarity, structure and consistency. 

My presentation abilities improved as a result of developing and preparing the the elevator pitch. It tested my abilities to explain complex ideas in a clear, interesting manner such that the target audiences could understand. I also found out that my confidence increases significantly when I understand the material and have time to rehearse. My group members and I were able to improve our delivery and increase the impact of the pitch by practicing. 

Overall, this project changed my view of learning, from focusing solely on content to appreciating the importance of communication, collaboration, and self-awareness. These skills are just as important  as technical knowledge, and I will carry them forward into future group collaborations and real-world challenges.

Hwang Kai Sheng's Additional Final Draft Reader Response

 

The DJI Mavic 3 Enterprise (M3E) is a versatile and compact drone, designed for various applications such as mapping, asset inspection, and real estate photography, among others. Drones provide accessibility, efficiency, safety, and cost-effectiveness across industries by covering large areas quickly, reducing manpower and equipment costs, safely accessing hazardous terrains, and offering high-resolution, real-time data that informs decision-making. The DJI Mavic 3 Enterprise includes key features such as a Real-Time Kinematic (RTK) module for centimeter-level accuracy, a 4/3 CMOS Hasselblad camera, and a 45-minute flight time, which enable precise and efficient data collection for land surveying (DJI, n.d.). Additional features include a foldable design for portability, advanced obstacle avoidance to enhance reliability, and seamless integration with DJI software, making it a versatile, affordable, and user-friendly choice for professional surveyors.

Despite M3E having low light performance, its RTK module for precise mapping and enhanced efficiency through advanced automation makes it an indispensable tool for industries requiring accurate data collection, streamlined workflows, and secure navigation in complex environments.

One reason the M3E is an indispensable tool is that it is equipped with an optional Real-Time Kinematic (RTK) module that provides centimeter-level precision, making it ideal for accurate mapping in civil engineering applications. According to DJI Enterprise (2023), the RTK module enables real-time positioning with high accuracy, reducing the need for Ground Control Points (GCPs) in surveying projects. This allows engineers to skilfully create 3D models and extremely detailed topographic maps. The integration of RTK technology greatly increases the accuracy of aerial surveys, ensuring that geospatial data collected is precise enough for infrastructure planning, land assessments, and construction progress monitoring. Without RTK, traditional GPS-based mapping would be less accurate, requiring manual corrections and additional site visits. The RTK module revolutionizes civil engineering workflows by reducing errors and increasing efficiency in mapping projects. By minimizing the dependency on GCPs, engineers can complete surveys faster while maintaining high data accuracy (DJI Enterprise, 2023).

Moreover, Huang et al. (2023) stated that the M3E improves efficiency and accuracy in aerial operations through its advanced automation features, such as intelligent flight planning and automated data collection. The M3E employs fully autonomous flight modes like corridor mapping and terrain following, which enables it to automatically adjust its altitude in response to changes in terrain and follow predetermined flight paths without manual intervention. These features help streamline operations associated with more complex missions such as surveying and inspecting infrastructures. Advanced automation minimizes human input during missions, ensuring more consistent and accurate data collection. The automated flight planning feature enables users to define and optimize flight paths for large-scale surveys, which saves time and effort compared to manual flight operation. Moreover, terrain-following automation allows the drone to fly safely and maintain consistent ground clearance over varying landscapes, thereby avoiding obstacles or crashes. The integration of advanced automation not only enhances the Mavic 3E’s operational efficiency but also increases the safety and accuracy of the operations, making it an indispensable tool for civil engineering applications, particularly in large-scale mapping, infrastructure inspections, and construction site monitoring.

The DJI M3E introduces notable enhancements in low-light performance, but its capabilities still fall short when compared to higher-end enterprise drones. The M3E features a 4/3 CMOS 20MP sensor with 3.3μm pixels and an intelligent low-light mode that promises better visibility in dim lighting conditions (DJI, n.d.-a). Unfortunately, there are no infrared or thermal imaging options in this model, something that the Matrice series drones from DJI do offer (DJI, n.d.-b). The M3E's heightened sensor and pixel size do give it an edge when it comes to clarity during low-light conditions, but it is still reliant on visible light, making it less effective for night time inspections, underground mapping, or foggy conditions. In civil engineering applications, this limitation can reduce operational flexibility, as engineers may struggle to capture clear imagery in early morning, late evening, or poorly lit environments. Thus, despite its improved low-light capabilities, the M3E may not be the best choice for projects requiring 24/7 aerial monitoring or operations in severely low-light conditions. However, it remains a cost-effective and efficient option for daytime and moderate low-light mapping tasks.

In conclusion, while the M3E's low light performance may present challenges in certain conditions, the RTK module, along with the advanced automation and mapping capabilities it possesses, makes it exceptionally useful for industries that prioritise precision, efficiency, and safety. The RTK module provides centimeter-level precision, ensuring highly accurate data collection for surveying and mapping tasks, while the automation features facilitate the flight planning process, reducing the need for manual intervention. Moreover, its advanced obstacle avoidance and terrain-following abilities ensure secure navigation, even in complex and cluttered environments. Altogether, these specifications render the M3E an indispensable tool for improving workflows, reducing manual labour, and delivering precise, real-time data for large-scale infrastructure projects. Its accuracy, automation, and portability make it an essential tool for contemporary civil engineering procedures, providing a balanced solution for surveying jobs of all sizes.

Technical report (Introduction)

 Introduction

This report is written in response to a request for proposal to introduce the use of bio-based materials into civil engineering to promote a sustainable and healthier building environment. It aims to provide Takenaka corporation with an overview of how the use of hempcrete material in construction helps address climate change, ensuring benefits to both environment and humans. This report will cover Singapore’s and the world’s climate situation and existing materials used in construction work and how it affects and increases the rate of climate change and the safety of humans in all aspects. The report will then discuss the science behind the proposed material. 


1.1 Background

This section is where general information about the topic of research and emphasises the main aim of the study. (Why are we doing this)


1.1.1 About Takenaka Corporation

Takenaka Corporation is a historic and forward-thinking construction firm with a strong reputation for innovation, sustainability, and cultural preservation. Its blend of traditional expertise and cutting-edge technology has made it a key player in shaping Japan’s built environment and a respected name in global construction. Takanaka has participated in high-profile sustainable construction projects that adhere to international green building standards, such as LEED (Leadership in Energy and Environmental design). Takenaka Corporation also places a strong emphasis on sustainable engineering and has integrated environmental responsibility into its core business practices (Takenaka Corporation, n.d.).

1.1.2 Overview of climate change and how it affects both earth and humans

Climate change refers to variations of the average weather trend in the long run that depict the Earth's local, regional and global climates (Velev,2024). Even though there are many natural causes that impact the Earth’s climate, a significant reason is human civilization. Scientists agree that due to the effects of human activities such as urban development and mainly due to the carbon emission from human activities where from 1750 to 2020 the concentration of carbon dioxide has risen by 48%. This leads to widespread and severe effects on the environment, economy and human life. Climate changes’ effects on the Earth include rising sea levels, increasing temperatures and ecosystem disruptions. Consequently, this causes problems such as rising sea levels, more drought and heat waves, longer wildfires and changes in precipitation seasons. The Earth and humans being interlinked, the consequences have a direct impact on humans. For example, drought and heat waves affect livestock, crops and with limited water supply, many everyday routines such as cooking and cleaning are significantly impacted. (Drought, heatwave threaten, Recently, in China’s agriculture region they were under the threat of extreme drought conditions and heatwaves that destroyed the yielded crops and prolonged the process of harvesting. This indicates that no matter first world or third world country, everyone is at high risk and facing the alarming impacts of climate change. In the long run, climate change would ultimately lead to significant economical, health related and political issues in terms of inflation, food shortages and political disputes on how to battle it. 


1.1.3 What is sustainable engineering and how will it affect climate change

Sustainable engineering involves designing and operating systems that use resources without harming the environment (Wikipedia , n.d.). By practising sustainable engineering, engineers utilise renewable energy, reduce waste and pollution to create efficient systems that last over time (University of Strathclyde, n.d.). Sustainable engineering also allows engineers to reduce the effects of climate change by developing renewable energy technologies like solar, wind and hydro power. This allows engineers to rely less on fossil fuel which can reduce greenhouse gas emission (Engineering Institute of Technology, 2022). In addition, by improving energy efficiency, engineers can reduce overall energy consumption , contributing  to emission reduction (Scientist for Global Responsibility, 2021).Therefore, sustainable engineering serves an important role in combating climate change by implementing environment friendly solutions to ensure long-term sustainability. 


1.1.4. What materials are used in construction now?

Typical materials used in construction are mostly concrete, cement, steel, and bricks. These materials are finite, deteriorate over time, and very commonly used in construction throughout the world, contributing to climate change and are overall not a safe material to humans. 


Material

Concrete

Advantage: High durability and greatly fire resistant. 

Disadvantage: Production of cement emits significant Carbon Dioxide.

Cement

Advantage: Strong and flexible to do any shape the constructors want. 

DisAdvantage: Production of cement is not eco-friendly as it uses a lot of energy.

Steel

Advantages: Durable and recyclable.

DisAdvantage: Production of steel uses a lot of energy, impacting the environment. 

Bricks 

Advantage: Hard, durable, and low maintenance. 

Disadvantage: Some ingredients used to make bricks may be toxic to humans.


Table 1 shows the four most commonly used materials in construction and the advantages and disadvantages



1.1.5. Environmental disadvantages of current materials in construction

Current materials used in construction, such as concrete, steel, and bricks have major environmental disadvantages due to their high carbon footprints, resource depletion, and energy-intensive production processes. Concrete production contributes to around 8% of global carbon dioxide (CO₂) emissions because of the chemical process of turning limestone into clinker and the energy consumed during cement production (Miller, 2019). Furthermore, habitat destruction and depletion of natural resources can result from extraction of raw materials for bricks and concrete, such as sand, gravel, and limestone (Smith & Johnson, 2021). Likewise, because steel relies on fossil fuels to heat and refine iron ore, it contributes significantly to the CO₂ emissions (Jones, 2020). The environmental impact of these materials is not only due to their direct emissions but also the energy needed for their production and transportation, and this causes never-ending resource consumption and environmental degradation. Global issues like climate change and biodiversity loss are made worse by the extensive use of non-renewable resources in the manufacturing of building materials, which pollutes the environment and damages ecosystems. Therefore, the construction industry needs to look into alternatives like recycling, sustainable materials, and energy-efficient construction practices to lessen these negative environmental effects. The construction industry can greatly reduce its ecological impact by switching to greener materials like bamboo, recycled steel, and low-carbon concrete (Miller, 2019).



1.2 Problem statement

Currently, construction companies are using materials that are both non-sustainable and unsafe for humans. This contributes to the increase in rapid climate change and additionally leading to more harmful effects on humans. The goal is to promote and encourage the use of hempcrete into construction companies for a more sustainable and safer environment, especially in museum constructions where it concerns both the environment and have a large scale of humans visiting the site.


1.2 Purpose statement

This report proposes to Takenaka corporation to integrate hempcrete, a bio-based material, into traditional construction practices to minimize environmental impact, encourage resource efficiency and improve the health and well-being of residents.

More of its features include foldable design to ensure portability, and advanced obstacle avoidance to enhance reliability, and seamless integration with DJI software streamlines workflows to make it versatile, affordable, and user-friendly choice for professional surveyors.

The Mavic 3 Enterprise revolutionizes aerial operations with its RTK module for precise mapping, enhanced efficiency through advanced automation and improved safety with obstacle avoidance, making it an indispensable tool for industries requiring accurate data collection, streamlined workflows, and secure navigation in complex environments. 

According to E38 survey solutions website (n.d.), 'DJI Mavic 3 Enterprise Series RTK module dramatically reduces the number of ground control points (GCPs) needed'. When surveying, a drone without RTK should have GCPs spaced no more than 500 feet apart. However, with the RTK module, three GCPs would be sufficient. RTK module improves the accuracy of the GPS tags on every image by allowing the DJI Mavic 3E to receive GPS satellite data along with correction signals from a base station. 

According to DJI enterprise (n.d.), DJI Mavic 3E supports the latest software, Pilot 2 and FlightHub 2, and it offers several advantages for fleet management, mission planning, and real-time collaboration. It would be able to automatically generate 2D orthomosaic maps in real-time using the Mavic 3E's imagery, and this is essential in search and rescue missions. This integration allows live video streaming where the real-time drone video feeds can be shared with the remote teams via the clouds, therefore improving decision making during operations.  It also allows mission planning and annotation, where the operator can create and share waypoints, flight routes, and annotations with team members, as well as to geo-tag important locations. DJI Mavic 3E can also use Pix4D mapper and ArcGIS software for data processing and create 3D models of the area relief. Studies by Igor.B (2019) shows that 

The DJI Mavic 3E is equipped with an omnidirectional obstacle sensing system, providing 360-degree obstacle detection for safer and more reliable flights. It utilizes multiple vision sensors and an advanced processing system to detect and avoid obstacles in all directions. GPSworld (2021) states that 

The APAS 5.0 (Advanced Pilot Assistance System) uses real-time data from all sensors to automatically maneuver around obstacles and allows smooth obstacle without abrupt stops. The Advanced Return-to-Home (RTH) scans the environment and automatically selects the safest, most efficient route back to the home point.


However, although DJI Mavic 3 works with Pix4D for data processing, it does not support Pix4DCapture. Hence, DJI Pilot 2, which is the official DJI app, would be needed for flight planning and data capture.

Summary and thesis draft #1

 

Summary

The Mavic 3 Enterprise is a versatile, compact drone designed for various applications like mapping, asset inspection, real estate photography, and more (as summarized by chatGPT).

The combination of accessibility, efficiency, safety, cost-effectiveness, and data collection makes drones highly valuable across multiple industries. Drones ae able to cover large areas in a fraction of the time. It is cost saving as it eliminates the need for extensive manpower and heavy equipment. Drones can easily access challenging or hazardous terrains, ensuring safety and feasibility in remote areas, allowing us to collect high resolution, real time data allowing surveyors to make informed decisions quickly.

According to the DJI Mavic 3 Enterprise’s website, it contains features such as a ‘RTK(Real time kinematic) module for centimeter-level accuracy, 4/3 CMOS Hasselblad camera, and 45-minute flight time’, enabling precise and efficient data collection for land surveying. More of its features include foldable design to ensure portability, and advanced obstacle avoidance to enhance reliability, and seamless integration with DJI software streamlines workflows to make it versatile, affordable, and user-friendly choice for professional surveyors. 


Thesis statement

The integration of Mavic 3 Enterprise with RTK technology and thermal imaging enhances efficiency, reduces costs, and improves safety across industries such as construction, infrastructure assessment, making it an essential tool for modern engineering workflows.

Body paragraph

According to E38 survey solutions website, 'DJI Mavic 3 Enterprise Series RTK Module dramatically reduces the number of ground control points (GCPs) needed.' When surveying, a drone without RTK module should have GCPs spaced no more than 500 feet apart. However, with the RTK module, three GCPs would be sufficient. RTK module allows the DJI Mavic 3E to receive both GPS satellite data and corrections from your base station, which improves the accuracy of the GPS tags on every image. With the DJI Mavic 3 Enterprise Series RTK Module, you can achieve centimeter-level accuracy, both horizontally and vertically.

Reflective Thinking to Writing a Reflection as a Process

 

Ideal

 To be punctual in school

Reality(gap)

 I reach school on time once in a blue moon

Causes/Conditions

 I usually wake up one hour before leaving my house (to reach school on time), but always procrastinate right before leaving house. 

Effects/Results

 I use my phone before leaving house

Goal

 To reach school on time so that I don't miss any important lectures

Possible change

 -Do not use phone until leaving my house

- Wake up earlier to have ample time to prepare myself

Testing the

hypothesis >

solution

 In order to be punctual, I stop using my phone until I left my house

Outcome of

change

That approach worked, and I ended up reaching school on time everyday

Self Introduction letter

Dear Professor Blackstone, 

My name is Kai Sheng, I graduated from Nanyang Polytechnic with a diploma in Medicinal Chemistry, and I am currently pursuing Bachelor in Civil Engineering in SIT. The reason for this huge change in the field of study is simply the lack of interest, and there is this quote that always resonates with me "Time you enjoy wasting is is not wasted time" by Marthe Troly-Curtin. Therefore, I decided to try engineering, which was strongly related to mathematics, and solving mathematical problem is something I enjoy.

Having ISTJ as my personality trait, I like to spend time alone during my free time. Some of the things I enjoy doing are going to the gym, play mobile games, listening to music and sleep. I personally feel that doing these things makes me feel at peace and brings about benefits too. 

One of my strengths is being able to stay calm in a messy situation which allows me to maintain my composure and think straight. I am also very meticulous in every task that I do to deliver an up-to-standard result, and always ensure that I am well prepared before any presentation.

However, there is one weakness that makes me feel inferior compared to most people, and it would be the lack of confidence to speak in front of a group of people. Even though I often step out of my comfort zone, I inevitably return to it. Hence, I hope that this module can shape me into a more confident person and speaker. 

Best regards,

Kai Sheng
