From bustling community spaces to the familiar blocks we call home, HDB estates form the very heart of everyday life in Singapore. What is lesser known to most, however, is that beyond building homes, HDB also plays a vital role in expanding our nation’s horizons, driving land reclamation projects that lay the groundwork for continued growth.

Driving these initiatives are civil engineers like Kai Yang, an HDB Scholar working in the Land Reclamation Department within HDB’s Building and Infrastructure Group. Contributing to the Polder Project at Pulau Tekong, Kai Yang is involved in work that creates concrete, lasting impact for the nation.

We caught up with Kai Yang to learn how he came to be at the forefront of shaping Singapore’s future landscape.

What inspired your passion for engineering?

I have always held deep respect for engineering as one of humanity’s oldest professions. I chose to become a civil engineer because I witnessed how civil engineers can positively impact and transform the world through the built environment. The work of civil engineers produces highly tangible results that provide a tremendous sense of accomplishment. Furthermore, since mathematics and science were my stronger subjects, I felt that a career in engineering would be an excellent fit for me!

What drew you to the HDB Scholarship?

Home holds a special meaning for everyone; it is a haven that we return to, where we feel safe and at ease. I viewed the HDB Scholarship as an opportunity to make a direct impact on improving people’s lives.

The scholarship enabled me to pursue my passion for civil engineering both in Singapore and abroad. It provided me with the opportunity to participate in a student exchange programme in Sweden, where I was able to broaden my horizons and learn different approaches to engineering.

How has your journey with HDB been so far?

Over the past six years, I have had the opportunity to experience different areas of work within HDB. I began my career in the Building Safety and Services Department, managing post-construction works and addressing defects and building maintenance issues. I was subsequently rotated to the Land Reclamation Department, where I joined the team managing the construction of the polder at Pulau Tekong.

Managing the polder construction was eye-opening. I had never been involved in such a massive project before. It encompassed a wide variety of works, including land reclamation, soil improvement, dike construction, and infrastructure development such as pumping stations, drains and roads. The project provided many learning opportunities, allowing me to gain valuable engineering experience.

That sounds like a huge project! How did you work with multiple stakeholders to make it happen?

Communication was key in a project of this scale. We adopted a collaborative approach, actively engaging with all stakeholders in key decision-making processes and maintaining open communication channels throughout the project. This involved regular site visits and workshops, alongside seminars and knowledge-sharing sessions, ensuring teams remained aligned towards common goals.

Not many will know of HDB’s work beyond housing. How would you describe what you do to them?

Beyond the polder at Pulau Tekong, there are ongoing projects in Changi and Long Island. I am part of the team managing the polder construction, working closely with local and international consultants, contractors, and experts to ensure the project is executed safely, efficiently, and on schedule.

I am also involved in research and development (R&D), which focuses on identifying challenges and developing innovative solutions to overcome them. In my role, I help to identify land reclamation challenges and contribute to developing a roadmap that charts the direction for R&D. This roadmap determines the type of innovative solutions we seek to explore.

Of all the projects you’ve been involved in, which stands out as a highlight?

The most memorable moment was undoubtedly when Prime Minister Lawrence Wong visited the polder project. It served as recognition of the historic milestone we achieved, marking the first time that Singapore has reclaimed land below sea level. It also validated the tremendous effort and dedication that the team and our partners invested in the project. Witnessing the extensive media coverage of the polder certainly instilled immense pride in our achievements.

How has HDB supported your career development?

HDB offers extensive learning opportunities for both professional and personal development. As an engineer, I am regularly encouraged to attend courses that enhance my engineering skills, pursue Chartered Engineer or Professional Engineer certifications and strengthen my personal competencies ranging from leadership to communication.

Any tips for those thinking about applying for the HDB Scholarship?

My advice would be to find out more about HDB’s work and its impact on Singapore! HDB has built a remarkable legacy in providing homes for close to 80% of Singapore’s resident population. If you resonate with HDB’s mission and want to positively impact the lives of fellow Singaporeans, I am confident that you will discover great fulfilment working with HDB!
