Tumasek, is today one of the leading corporations that specializes in civil & structure engineering, marine engineering and infrastructure-related industries in Sarawak and Malaysia. It has a very humble beginning and it started in the early 1980s as an independent small-time contractor. Even in the early days, Tumasek (formerly known as Syarikat Nasib Contractor) emphasized on a good corporate governance and accountability. As it grew, it formed strategic alliances with many listed engineering corporations and after 3 decades, today is able to stand tall and on par with many local and regional groups of companies. As the company grows, it becomes evident that it needs a bigger platform to focus on its core business activities. Thus the birth of Tumasek Reka Dan Bina Sdn. Bhd.

Tumasek is headquartered in Kuching with branches in Kuala Lumpur and other major cities in the region. These offices are managed by an international management team. As globalization is on the horizon, Tumasek needs to strategically diversify into other fields, e.g. oil & gas industries, oil palm plantation and others.

However, despite globalization and diversifications Tumasek remains true to its core values and principles which today has formed the cardinal pillars of the company.
