What is design verification?
Design verification is a process of evaluation where one or more competent people review the design documentation of a specific item of plant. This is done to ensure that the design complies with the technical standards or engineering principles specified for the plant.
The process of verification should include, but is not limited to:
- reviewing the performance requirements and design assumptions for the plant
- reviewing design calculations and/or undertaking independent calculations of criticalsections of the plant
- examining detailed design drawings, encompassing material specifications andmanufacturing and testing requirements
- assessing circuit diagrams and control systems (if applicable)
- reviewing the specifications for testing the plant
- reviewing the maintenance schedules for the plant.
If a plant design requires the involvement of multiple competent people to conduct the design verification, the design verifier must declare involvement of all individual competent people and their details.
Who can be a design verifier?
WHS General Regulations r. 252 - Who can be the design verifier
A person is eligible to be a design verifier if they are a competent person. Under the WHS General Regulations, a competent person in this situation is a person who has acquired through training, qualification or experience the knowledge and skills to design the item of plant, or verify the design, and is eligible for professional engineer membership of Engineers Australia. A competent person may also be determined by the regulator to be a competent person.
The person(s) carrying out the duties of the design verifier should be a person located or residing within the jurisdiction of the State of Western Australia or within Australia.
