The practice of PT. TRI MANDIRI JAYA USAHA was established when Hasan separated from PT Abdi Sarana Nusa ASN in Q2 2006. PT. TRI MANDIRI JAYA USAHA with our own equipment have operated for more than 10 years providing resources and skills in the civil component of oil and gas projects and individual mine site developments. Realizing that more was needed to be done with regards to effective skills transferring within the Civil Works environment and in particular in Indonesia today, the next challenge was to establish a sustainable Contract Mining entity that would reflect the demographics of the country. PT. TRI MANDIRI JAYA USAHA , known as TMJU was therefore born from a belief that sustainable development within the mining and civil engineering environment will happen if serious effort towards the incorporation of quality management, strong financial resources and competent construction skills was made. Our goal of a sustainable specialized mining and civil works contractor was reached quicker than planned and from Q2 2006 – Q2 2007 our entire BPREC Jonggol wellsite construction, access road and bridge project and Quad Energy Banten Sand Mine operation functioned under the TMJU banner. All designs and documentation including tender documents are prepared by TMJU personnel, and reviewed, approved and signed by Hasan. This provides internal quality control according to our ISO 9000 accredited quality management system as well as adherence to our professional indentity standards.
