PT TOA Tunas Jaya Indonesia is a Joint Venture company between TOA CORPORATION (JAPAN) and PT Tunas Jaya Sanur (INDONESIA) who are operating in the construction sector. TOA CORPORATION and PT Tunas Jaya Sanur marks a significant partnership in the construction industry. They come together to combine their expertise, resources and capabilities to undertake specific projects and cope with Indonesian construction market. This dynamic partnership was born from a mutual desire to thrive in an industry that constantly demands adaptation and evolution.
Both TOA CORPORATION (TOA) and PT Tunas Jaya Sanur (TJS) are well-established construction companies with a proven track record of delivering prestigious projects in their respective markets. Dating back in December 2017 TOA and TJS has built a strategic partnership to form a Joint Operation for the Construction of Cultural Hall Building in Badung Regency Government Center of Bali Province. The construction works were successfully completed and handed-over to the Client in September 2019. The building then named as “Giri Nata Mandala” is a 3-storey multi-purpose building for the Cultural Art Stage and Exhibition Hall with the capacity of more than 2,000 spectators.
Recognizing the benefits of the collaboration, TOA and TJS have decided to establish a joint venture company to pursue larger and more complex projects that require a broader skill-set and greater resources.
