Established in 2006

After more than 20 years involved in mechanical design and development projects across Australia and Internationally it was time to take that knowledge and experience direct to industry.

In 2006 I started Siviour Engineering, providing mechanical design and drafting services to industry. Over the proceeding years I worked on medium to heavy design and fabrication projects within Australia and overseas. Many of the projects were transport, Heavy Vehicle related. With this knowledge and experience I earned the qualification of: Recognised Engineering Signatory for Heavy Vehicle Modifications – RES.

Along with formal qualifications in Mechanical Engineering and Engineering Management I am also trade qualified in Fitting & Turning, bringing the practical and theoretical sides of engineering together .
