PSI is committed to HSE always being the first priority in any task undertaken. No job is so important, no task so urgent that we cannot discipline ourselves to do it safely.

Planning to achieve superior HSE performance adds value to a project by increasing productivity, improving schedule performance, encouraging lower employee turnover and reducing the overall project cost. Consequently, PSI is committed to creating an Incident/Injury Free work environment for our employees and Clients on all our projects.

Each employee must recognize the moral and legal responsibility for the protection and enhancement of the environment and be committed to performing environment protecting and enhancing activities on their project from inception to project closeout.

We strive to develop and provide products and services that have minimal environmental impact; are safe in their intended use; are efficient in their consumption of energy and natural resources; and can be recycled, reused or disposed of safely.

We establish and sustain a positive ‘zero harm’ culture across PSI managed sites.


PSI has successfully implemented a Quality Management System in accordance with ISO 9001:2015 international standard and certified by AsiaCertLine accredited by NCA. The accuracy of ISO 9001 regulations and the company performance are controlled by authorized ISO 9001 inspectors regularly.

The Quality Control Manual is used at all jobsites and details the quality activities of PSI personnel for self-perform projects. A quality manager is assigned to each project and is responsible for the implementation and coordination of the quality program.
