Our Journey

Founded in 2019, PT Sinergi Tunggal Abadi began its operations in the general supply sector, laying the foundation for a company built on reliability and service excellence.

In 2020, we took a significant step forward by expanding into steel structure fabrication, enabling us to supply critical fabrication support facilities such as gantry cranes, chambers, and other essential infrastructure. Alongside this, we also established a labour supply division to support the growing needs of the fabrication industry.

By 2021, our vision extended toward site construction, prompting us to officially acquire the Construction Services Business License (SIUJK) — a milestone that marked our entry into the construction sector and positioned us to handle more complex and large-scale projects.

In 2022, we proudly secured a major construction project: the development of Microsoft's JKT-05 data center in Cikarang, West Java. Our scope of work involved the installation of up to 970 tons of steel structure, completed with an exemplary safety record—achieving 10,000 working hours with zero Lost Time Injuries (LTI).

The year 2023 saw us reaffirm our commitment to quality through the successful attainment of ISO 9001:2015 certification, further validating our dedication to delivering excellence in every aspect of our operations.

Looking ahead to 2025 and beyond, PT Sinergi Tunggal Abadi remains focused on sustainable growth, continuous innovation, and providing the highest level of service and value to our clients—driven by the same passion and integrity that have shaped our journey from the very beginning.
