EVERY year in May in Sabah, something special happens in Penampang. People from all over Sabah, and even from other parts of Malaysia and overseas, gather at the Kadazandusun Cultural Association (KDCA) to celebrate Kaamatan, the Harvest Festival.

The atmosphere is filled with joy. The sounds of gongs echo through the air, dancers perform the graceful Sumazau dance, and colourful traditional costumes brighten every corner of the festival grounds.

For many visitors, Kaamatan is a time to celebrate culture, friendship and unity. But have you ever stopped to think about the remarkable engineering behind this wonderful celebration?

The truth is that without good engineering, a festival of this size would not be possible.

A Building That Welcomes Everyone

The KDCA Building, also known as Hongkod Koisaan, is one of Sabah’s most famous landmarks. Located in KM8 Jalan Penampang, Penampang district, the building stands proudly as a symbol of the Kadazan -Dusun community and the rich cultural heritage of Sabah. Its design is unique.

Unlike many modern buildings made entirely of glass and concrete, KDCA reflects local culture through its distinctive roof shape and traditional architectural features.

When visitors first see the building, they immediately know they are looking at something truly Sabahan. Yet behind its traditional appearance is a modern building carefully designed by engineers, architects and builders.

The building is strong, safe and functional. It is able to accommodate large crowds during festivals, conferences, exhibitions and community events throughout the year.

It is more than just a Building Most people see only the beautiful building. Engineers see something more.

They see the roads that allow thousands of vehicles to enter and leave safely. They see the drainage systems that prevent flooding during heavy rain.

They see the electrical systems that power the lights, sound equipment and exhibition halls. They see the water supply systems that serve thousands of visitors.

They see the structural design that allows large halls to safely accommodate huge crowds. These are things that visitors rarely notice, but they are essential for the success of every event.

In engineering, success is often invisible. When everything works smoothly, people simply enjoy the experience without realizing how much planning has taken place behind the scenes.

A Festival That Becomes a Small City

During the Kaamatan Festival, the KDCA compound becomes like a small city. Thousands of people arrive every day. Food stalls operate from morning until night. Cultural performances take place at different locations.

Exhibitions attract visitors of all ages. Managing such a large event requires careful planning. Traffic must flow smoothly. Water and electricity must be reliable. Public toilets must be maintained.

Waste must be collected regularly. Emergency services must be ready at all times. All these activities depend on good engineering and proper management.

Without these systems, visitors would not be able to enjoy the festival comfortably and safely.

Learning from Our Ancestors

One of the most interesting places within the KDCA compound is the Cultural Village. Visitors can explore traditional houses built by various indigenous communities of Sabah.

These houses are not only cultural treasures; they also contain valuable engineering lessons. Long before modern technology existed, our ancestors knew how to build homes that suited Sabah’s tropical climate.

The houses were built on stilts to avoid floods and improve air circulation. Large roofs provided shade from the hot sun and protection from heavy rain.

Open spaces allowed natural ventilation to keep the houses cool. Today, engineers call these ideas sustainable design and passive cooling. Our ancestors simply called it common sense.

The Cultural Village reminds us that modern engineering can learn a great deal from traditional knowledge.

Engineering Supports Culture

Many people think engineering is only about roads, bridges and tall buildings. In reality, engineering also helps preserve culture. Without suitable facilities such as KDCA, it would be difficult to organize major cultural events, exhibitions and educational programmes.

The KDCA complex provides a place where traditions can be celebrated and passed on to future generations. Young people can learn about their history. Visitors can experience Sabah’s unique culture. Communities can come together and strengthen their bonds.

In this way, engineering helps keep culture alive.

Supporting Tourism and the Economy

The KDCA Building and Kaamatan Festival are also important for Sabah’s tourism industry.

Every year, visitors travel to Penampang to experience the festival. They stay in hotels, dine at local restaurants, purchase handicrafts and support local businesses.

This creates jobs and generates income for the local economy. Good infrastructure plays an important role in making this possible. Well-designed roads, safe buildings, reliable utilities and comfortable public spaces all contribute to a positive visitor experience.

KDCA shows how engineering can support both cultural preservation and economic growth.

A Valuable Lesson

As Sabah continues to develop under SMJ 2.0, many new infrastructure projects will be built. We will see more roads, water supply systems, flood mitigation projects and public facilities.

These developments are important. However, KDCA teaches us that development is not only about constructing buildings and infrastructure. It is also about creating places where people can gather, celebrate their heritage and build stronger communities.

The best engineering projects are those that improve people’s lives while preserving their identity and culture.

A Proud Symbol of Sabah

Today, the KDCA Building stands as one of Sabah’s most important landmarks. It is a place where culture, heritage, tourism and engineering come together. Every year, during Kaamatan, thousands of people gather to celebrate the spirit of gratitude, unity and harmony.

As they enjoy the festivities, many may not notice the engineering that makes everything possible.

Yet behind every successful event are engineers, planners, architects and maintenance teams working quietly in the background. The next time you visit KDCA, take a closer look.

Look at the building, the roads, the open spaces and the cultural village. You will discover that KDCA is more than a festival venue. It is a wonderful example of how engineering can serve people, preserve culture and help build a stronger Sabah for future generations.

That is what makes the KDCA Building in Penampang not only a cultural treasure, but also a true engineering masterpiece.
