    TCC's senior management recognised at the establishment of the company that attention to Health, Safety and Environment (HSE) was a primary issue for the company's success. As the core management team has worked in the industry for many years and developed their experience from large international projects with international clients the belief in HSE is central to TCC's business philosophy and ethics. From its conception in 2002 TCC has established its HSE credentials within the industry with its better than average perfomance and has had numerous awards from its many projects which attest to its commitment. Central to this philosophy is the belief that a positive attitude to HSE performance returns a positive attitude from the workforce. This not only safeguards the workforce but also enhances overall project performance.

    The core values for HSE on every project are:-

    - HSE is the first priority
    - All personnel are primary responsible for HSE
    - Drugs and alcohol are strictly forbidden
    - Base target is incident free projects

    TCC sets its HSE planning around these core values and will implement several innovations, on a project by project basis, in order to achieve these and give the continued improvement currently being achieved.




    The Companion Group was officially founded in the year 2004. �The original activities of the company consisted mostly of the fabrication and erection of piping and steel structure. Following an ongoing development of its operations, we have enlarged scope of work cover the entire construction works, which are civil work, steel structural fabrication and installation work, equipment installation work, module assembly work, plant maintenance and service work, including engineering work. Additionally, we have expanded the business into international market such as Singapore, Myanmar, Australia, etc.

    The Companion Group has not ceased to grow and develop over the years until the present. We have continuously serviced with expert operation staffs and professional team; this has consequently led to our rapid development. In the year 2007, the quality management system of The Companion Corporation Company Limited was certified with ISO 9001:2000, that ensures the quality and timely services for the clients.

    For the next step, we expect to be the first EPC company of Thai by Thais that takes the responsibility on the engineering, procurement and construction for various industrial works. We also intend to be recognized extensively as the world-class company and satisfy the needs of all clients as our goal.
