functional requirements along with the associated performance conditions to the agreed time, cost and 

quality. 

II Responsibilities 

Solution development and delivery: 

1. Develop and implement strategies for delivery of the discipline-related components of design, including 

use of the supply chain. 

2. Deliver a safe, fit-for-purpose, fully integrated and operable design solution that meets product 

requirements, and includes appropriate validation and verification. 

3. Manage the production of fit-for-purpose discipline-related design deliverables that define and preserve 

the design intent and are organised and align with the plant configuration, as appropriate. 

4. Ensure the design solution is able to be manufactured, constructed, commissioned, handed over, put 

into operation, maintained and decommissioned, and that Life Time Records are delivered. 

5. Ensure all discipline-related technical, safety and engineering risks are identified, owned and managed 

6. Define and execute a discipline-specific risk based assurance strategy and call appropriate engineering 

or design reviews, with appropriate independence, in a timely manner. 

7. Support the PEM in providing engineering design support to work scope definition throughout 

procurement, construction and commissioning project phases. 

8. Develop and deliver work in line with the Project Delivery Fundamentals1

. 

Safe and Legal: 

9. Support development of the hazard management strategies, safety case and associated 

implementation systems and provide pragmatic design substantiation.
