What's your job about?

AECOM is a global infrastructure firm that designs, builds, finances, and operates infrastructure assets for public and private organisations. As a new graduate mechanical engineer in the Buildings and Places team, I am primarily responsible for designing HVAC systems for various clients in large-scale buildings. This involves performing calculations to determine airflows and ensuring compliance with the Building Code of Australia standards. 

Each day, I conduct heat load calculations, design ductwork layouts, and select appropriate HVAC equipment. I also collaborate with other engineers and architects to integrate HVAC systems into building designs. A typical project might involve creating detailed drawings, running simulations to optimise system performance, and coordinating with suppliers to ensure timely delivery of equipment. For example, in a recent project, I worked on designing the HVAC system for a new Defence facility.

This required precise calculations to ensure the system could handle the specific environmental conditions and meet stringent security requirements. Throughout the project, I regularly reviewed my designs with a principal mechanical engineer to ensure accuracy and feasibility. While the basic concepts of my work, such as airflow and temperature control, can be understood by a teenager, the more complex aspects, like detailed calculations and equipment scheduling, are more challenging. An interesting detail is that much of my work involves Defence-related projects, which adds an extra layer of complexity and confidentiality to my role.

What's your background?

I lived on the Gold Coast my entire life until about six months ago when I moved to Brisbane for my job. A primary school trip to Questacon in Canberra sparked my passion for engineering. Witnessing a robotic arm playing tic-tac-toe with people inspired me to pursue a career in this field. I was part of my high school’s STEM program. One of the highlights was a trip to NASA's camp in Houston, Texas, where I was fascinated by the construction and operation of rockets. This experience further fueled my interest in engineering. Following high school, I was accepted into Griffith University to pursue a Bachelor of Engineering (Hons). After four challenging years, I graduated with first-class honours. As graduation approached, I began applying for jobs in my field and was thrilled to receive an offer from AECOM as a graduate mechanical engineer in the Buildings and Places business line. Over the past six months, I have learned a great deal and continue to grow in my position.

Could someone with a different background do your job?

Yes, it is entirely possible to do my job with a different background. While a degree in engineering is common, skills in HVAC design, heat load calculations, and air balance assessments can be acquired through various educational paths and practical experience. Key characteristics and skills for this job would include attention to detail, problem-solving abilities, strong communication skills and adaptability. You don’t need to know everything coming into the job, but you need to be willing to learn.

What's the coolest thing about your job?

The satisfaction of seeing a well-designed HVAC system come to life and function efficiently. Most of my work is Defence-related and knowing that these large-scale projects will make a significant impact makes it all worthwhile. Additionally, having the chance to visit sites and see my designs in action firsthand is incredibly rewarding.

What are the limitations of your job?

As a graduate, I don't bear a lot of responsibility now, but tight deadlines often require a few reasonable hours of overtime to ensure everything is done to a high standard. The job isn't physically demanding, but it can be mentally exhausting due to the precision and attention to detail required. This role demands a strong commitment to accuracy and the ability to handle stress effectively.

3 pieces of advice for yourself when you were a student...

1. Make the most out of the time you spend at university. While it might be stressful at the moment, you will miss the fun times you spend with friends and the crazy nights hosted by the university. 
2. Always seek to learn beyond your coursework. While coursework is important, being curious to learn things outside of this is what makes it enjoyable.
3. Prioritise your mental and physical health. Regular exercise, a balanced diet, and mindfulness can make a big difference in your overall well-being.
