System development


The Quality Management System (QMS) is an internally development system that has been built on the back of the initial system that was written around the ISO 9001 template. It was restricted to the company’s core business, at that time, namely the execution requirements for the fabrication and erection of structural steel and process piping. As the company has grown and developed the scope of the system was expanded to encompass civil works.


It was then decided to expand the system to cover all the company’s seven departments and a restructured and expanded system has put in place and is currently being implemented across the company at different rates dependent on the specific needs dictated by the workload and client qualification requirements.


The system is managed by a Quality Management Representative (QMR), identified on the organisation chart

Company accreditation

Inception in 2005

The initial system was accredited at its inception in 2548 (2005) in accordance with ISO:9001 2005. One result of accreditation is that the system is subject to third party audit every six months and requires renewal every 3 years.

Renewal in 2008

The first renewal in 2551 (2008) and the accreditation was upgraded to ISO:9001 2008; several adjustments being made to accommodate the improved rules.

The second renewal was in 2011

The second renewal was in 2554 (2011) and continued with ISO:9001 2008.

The third renewal was in 2014

The third renewal was in 2557 (2014) and continued with ISO:9001 2008.

The fourth renewal was in 2017

The fourth renewal was in 2560 and the accreditation was upgraded to ISO:9001 2015, several adjustments being necessary and some additional requirements being introduced.

Health safety, security and environment processes and procedures

Health safety, security and environment processes and procedures are currently incorporated within the QMS and no separate accreditation process has been started. The structure of the QMS will allow these items to be extracted and have separate accreditation with ISO and OSHA in the future if the Company management determines that there may be some benefits accrued.
