Summary Reader Response (Draft 2)

DJI’s website, titled “Matrice 300 RTK” (n.d.), introduces the DJI Matrice 300 RTK as a versatile industrial drone capable of meeting the demands of various professional applications. When folded, including propellers, it measures 430 x 420 x 430mm and weighs approximately 6.3kg with two batteries included. According to DJI’s website, the drone features a smart inspection mode and advanced safety features, which are advantageous for inspections in challenging environments. With robust flight safety features, including obstacle avoidance and automated return-to-home, it ensures safe navigation around structures. The drone's smart inspection modes, exemplified by AI spot-check, automate inspection tasks, enhancing efficiency and data precision in civil engineering assessments. Additionally, its integrated RTK Technology guarantees high-precision positioning for accurate geospatial data, crucial for detailed mapping and surveying of construction sites. In summary, the M300 RTK excels as an ideal tool for civil engineering inspections, ensuring superior safety, efficiency, and precision in gathering crucial infrastructure data.

The use of drones in the civil engineering industry has revolutionized project efficiency and data collection, offering advantages in surveying, monitoring construction sites, and infrastructure inspection, enhancing the overall effectiveness and precision of the construction process.

In contrast to the traditional surveying method of using ground-based equipment, such as total stations and GPS receivers, which can often be time-consuming and resource-intensive, drones offer a more efficient alternative. Drones are capable of capturing numerous ground images from various angles, creating thousands of accurate data points, including geo-references, elevation points, and colours (“How are Drones Used in Surveying”, 2021).  As a result, data can be collected more quickly and efficiently, providing engineers with a greater understanding of the site and reducing the risk of overall project errors (McNeil, 2023).

Drones also provide an efficient and accurate method for monitoring construction progress throughout the project’s lifecycle (Choi et al., 2023).  By regularly capturing aerial photographs, project managers can track the progress of the project, identify potential issues, and ensure adherence to plans and schedules, gaining a better insight into the construction progress all without the need to physically visit the site (Ayemba, 2018).

Equipped with advanced cameras, sensors, and data processing capabilities, drones offer benefits for infrastructure inspection in construction. Manual inspection can often be hazardous, difficult to access, and time consuming for workers. By using drones to capture high-resolution imagery and videos, dangerous situations such as unstable structures, debris, cracks, and other defects that need repairs can be identified quickly and efficiently (Choi et al., 2023). This allows workers to address the issue before it worsens or poses structural dangers. Thereby reducing safety risks and costs and improving the overall effectiveness of the construction process.

However, the use of drones in the industry has its drawbacks as it is weather dependent. Weather conditions such as heavy rain or wind might affect the quality of the visual data collected (Elena Ciampa et al, 2019). In windy conditions, drones might be blown off course, preventing them from maneuvering properly or gathering reliable data, which in turn might affect the precision of the construction process.

In conclusion, drone technology presents several benefits over conventional surveying, monitoring and inspection techniques, including increased efficiency, decreased expenses, and minimized hazards for laborers. However, the use of drones comes with its challenges as well, further improvements could be made to guarantee the use of drones in the construction industry. Nevertheless, as technology continues to advance, drones are expected to play an increasingly critical role in shaping the future of the construction sector.

Descriptive Reflection - Formal Introductory Letter

  Subject: Self-introduction letter  Dear Professor Blackstone,  I am writing to introduce myself to you formally. I am Shirlyn Ong, a year one civil engineering student at the Singapore Institute of Technology (SIT), currently enrolled in your critical thinking and communicating module. I graduated from Singapore Polytechnic with a civil engineering diploma in 2023. My interest in the civil engineering field sparked ever since I was young. My father, a civil engineer, often introduced and explained many of his structural drawings to me. Ever since then, I constantly questioned how skyscrapers and bridges were built. Thus, it motivated me to pursue my studies further in this course.  I would consider my communication strength to be empathic. I would often put myself in others’ shoes and understand their perspective before giving a reply; this includes being aware and acknowledging the other person’s emotions and feelings. However, one communication weakness I have would be presenting i

Week 1 : The importance of communication skills for engineers

   “Communication skills are an essential component in the education of engineering students to facilitate not just students’ education but also to prepare them for their future careers.” Marc Riemer, Faculty of Engineering, Monash University (2007)   The significance of communication skills in the education of engineering students is emphasized in this paragraph. Communication skills are not only necessary for the student's academic journey but also play a crucial role in shaping their future careers. The implication is that proficiency in communication is a fundamental requirement for success as an engineer. Engineers must skillfully convey technical information, collaborate with colleagues, and articulate ideas effectively.
