Summary Reader Response Draft 4
by Leah, Duanghathai Sonna


In the article, “An Architect’s Guide to Building with Bamboo,” Vadot (n.d.) explains how bamboo is an alternative material that holds a place in the construction industry in time to come. He states that the inspiration for adopting organic materials came from the growing awareness of sustainable living. He mentions that bamboo has the potential to replace steel, but the only drawback is its fragility. Its core is prone to cracks during hot and humid weather, and when untreated properly before being used, the bamboo will decompose due to the microbes. He counters that with the bamboo’s strength-to-weight ratio, its production cost and its capability of growing rapidly anywhere in the world with minimal maintenance. Unlike conventional timber, classifying bamboo is hardly possible as its characteristics vary depending on the growth environment. Nevertheless, Vadot gives an example of how Colombia was able to adopt bamboo materials into their building craftsmanship. Based on the points explored in the article, it seems clear that although bamboo has great potential, Vadot could have elaborated more on the limitations that bamboo has that induce scepticism about incorporating it as a universal building material in the construction industry. 
 
First of all, bamboo lacks design guidance and uniformity. Lara et al. (2019) mention that its structural behaviour can have extensive variations depending on the species, the region where it was planted, age and moisture content. Boehland (2006) proclaims that the lack of universally recognised standards is a severe setback to the use of structural bamboo. This very fact has "kept architects and designers away from bamboo, even from expressing their requirements for bamboo as a building material.” Permits and structural calculations are difficult to obtain because there are no uniform standards, affecting bamboo’s reliability as a construction material. It needs to be engineered with other materials to allow for predictable properties, standardisation and less variability. Engineered bamboo products occur from processing the raw bamboo culm into a laminated composite. Sharma et al. (2020) state that these products allow the material to "be used in standardised sections" and have less "inherent variability" than the original material. 
 
Secondly, bamboo has low durability when it is not taken care of properly. It necessitates closely-monitored maintenance as Carrera (2003) states that bamboo is vulnerable when exposed to ultraviolet rays and rain. However, Kaminski et al. (2016) explain that when bamboo is kept indoors and protected, they can have a lifespan of up to 30 years. They also mention that the biological attacks on the bamboo caused by fungi and insects hinder its durability, deeming it as a disadvantage of the material. Adding on, they describe the need to add a chemical preservative such as boron to the bamboo, to deter fungal and insect attack or else the bamboo can deteriorate very quickly. As a result, due to bamboo's low durability and high-maintenance as a building material, it is unpreferred in the construction industry. 
 
Lastly, despite the numerous traditional and contemporary bamboo member connection methods, many factors are to be considered before construction. For instance, the availability of adequate manpower, as specific skills and craftsmanship are required to execute the jointing methods. As a single point of reference for the joinery techniques of bamboo have yet to be established, Murrow (2017) identifies the connection of bamboo structural members as a challenge. As a result, the lack of standardised guidance on bamboo connections is one of the risks for practical implementation in civil construction.
 
All in all, bamboo is easily obtainable across large regions of the world and has many advantages that include favourable material properties and financial savings. Nonetheless, Vadot could have been more precise in exploring the shortcomings of bamboo usage in the construction industry. Once the design code series is complete and comprehensive, the risk should be low enough for designers and engineers to consider bamboo as a credible and an alternative option as a green building material.

a letter from me to you

Subject: A self-introduction letter  Dear Professor Blackstone,  My name is Duanghathai Sonna, but you can call me Leah. I am honoured to take this pleasure to introduce myself to you. I graduated from Singapore Polytechnic in 2020 with a diploma in civil engineering with business, and I am currently attending Singapore Institute of Technology, majoring in civil engineering.  It was the combination of my very own explorations, along with the guidance my lecturers have provided me while I was in school, that confirmed this discipline of engineering is the right path for me. Besides my academic aspects, I have a few hobbies that contributed to my self-development. In the field of sports, I was appointed as the vice-captain in the school's soccer team, where I had the opportunity to lead a group of women back in my polytechnic days. From that leadership role, I tremendously sharpened my communication skills and that definitely helped me become the assertive speaker I am toda...

the importance of communication skills for engineers

“Employers identify communication as one of the basic competencies every graduate should have, asserting that the ability to communicate is valuable for obtaining employment and maintaining successful job performance.”  Sherwyn Morreale, Michael Osborn & Judy Pearson, Professors of Communication (2000) Explanation As stated by Sherwyn Morreale, employers emphasise on the importance of graduates being able to communicate well as it is a fundamental skill to possess. In order to secure a position in a company, one has to excel in the job interview and it will be an advantage with clear communication. Having effective communication skills aid in many aspects of the working world by increasing productivity especially where many interactions take place, for example, writing emails, meetings and pitching ideas in or out of an organisation. All in all, graduates should have communication skills as they are very useful in securing a job as well as improve their overall job satisfaction...
