OUR JOURNEY
1982
The Beginning
Born and raised in Medan, our founder spent his childhood there before his family relocated to Surabaya. He later pursued a degree in Civil Engineering, where his passion for construction took shape.
During his final years at university, he spent two years as an intern on an international construction project in Kupang, gaining invaluable hands-on experience. After graduation, he continued his career with an established construction company, building the knowledge and practical expertise that would later become the foundation of the company.
1990
Company Founded & First Industrial Project
Driven by a vision to build with integrity, quality, and trust, this company was officially established in Surabaya under the name PT. Metraya Pratama.
Operating from its first first office on Jalan Gatotan with a team of five employees, the company completed its first industrial project, marking the beginning of its journey in industrial construction.
1997
Growing Together
As long-term relationships with clients continued to grow, so did the company. The team expanded to around twenty employees, and the office relocated to Villa Bukit Mas to support increasing project demands and a growing portfolio across Indonesia.
2006
A New Identity
The company relocated its headquarters to Araya and officially adopted the name, PT. Medex Prima.
The name “Medex”, derived from “Medan Express” reflects the founder’s roots in Medan and the company’s commitment to providing responsive, practical construction solutions without compromising quality. Introduced during a period when the founders’s younger brother joined the business, the new identity marked a fresh chapter in the company’s evolution.
As the company continued to grow, it expanded its capabilities and earned the trust of larger industrial and commercial clients across Indonesia.
2014
Preparing the Next Generation
The founder’s successor joined the company and began his journey from the ground up.
Rather than entering directly into a leadership role, he worked across various operational positions to understand every stage of the business, gaining firsthand experience in the challenges, responsibilities, and values that define the company.
2021
Transformation
As the successor assumed the role of Commissioner, the company entered a new phase of transformation. While preserving the values established by the founder, he introduced initiatives to strengthen the company’s long-term competitiveness, including a renewed corporate identity, stronger brand positioning, digital presence, organizational systems, and management practices.
These efforts were brought together under a renewed spirit embodied in the company’s tagline: Building Future.
Today
Looking Forward
Today, PT. Medex Prima continues to partner with clients across Indonesia in delivering industrial facilities and a wide range of construction projects. Guided by our core values of Ethical, Hospitality, and Practicality, we remain committed to building not only reliable infrastructure, but also lasting partnerships founded on trust, professionalism, and shared success.
LEADERSHIP
“A legacy built on trust. A future built with purpose”
For nearly four decades, Medex has grown through the values established by our founder and carried forward by the next generation. While each generation brings its own perspective, both share the same commitment: building lasting relationships, delivering quality work, and creating value that extends beyond every project.
“When I founded this company, my goal was simple: to build every project with honesty, quality, and responsibility. I believed that if we consistently delivered our best work and treated people with respect, trust would follow.
Over the years, I have learned that buildings may stand for decades, but it is our integrity and the relationships we build that truly define our company. I am grateful that these principles continue to guide Medex as it enters the next chapter.”
Rudy Irsan
From one generation to the next, our commitment remains the same: to build with integrity, strengthen relationships, and create lasting value for everyone we serve.
“Growing up, I witnessed my father build Medex on trust, integrity, and genuine care for clients. My responsibility is to preserve these values while preparing the company for the future through stronger systems, clearer direction, and a culture rooted in Ethical, Hospitality, and Practicality.
I believe we build more than facilities. We help businesses grow, create opportunities, and support families and communities. Our aspiration is to be more than a contractor–a trusted partner who creates lasting value for our clients, our people, and society.”
