**Building on our past. Ready for the future**

Worley is a general professional services company of energy, chemicals and resources experts. We partner with customers to deliver projects and create value over the life of their assets. We’re bridging two worlds, moving towards more sustainable energy sources, while helping to provide the energy, chemicals and resources needed now.

**Major Accountabilities of Position**:

- Study and small project delivery:

- Plan, lead and deliver small-value Worley studies, small Front End Engineering Design packages, plant modification projects and engineering packages from Conceptual Engineering through Pre-Front End Engineering
- Design, Front End Engineering Design and selected Detailed Design scope.
- Prepare and control the study execution plan, deliverable register, assumptions register, decision register, action tracker, risk register and stakeholder engagement plan.
- Coordinate multi-discipline work so that process, safety, layout, mechanical, piping, pipeline, electrical, instrumentation, civil, structural, estimating, planning, procurement, construction, commissioning and start-up inputs are integrated from the outset.
- Ensure outputs are sufficiently mature for the agreed project phase, the required estimate class, the next investment or execution gate, and where applicable procurement, shutdown, turnaround, commissioning and start-up planning.
- Conceptual engineering, option identification and debottlenecking:

- Lead conceptual engineering for existing facilities, small projects, small Front End Engineering Design packages and plant modifications, including definition of constraints, operating cases, bottlenecks, interfaces, battery limits and technical success criteria.
- Identify feasible development,



debottlenecking and implementation options using process engineering judgement, site data, operating history, process models, equipment adequacy checks and discipline inputs.
- Eliminate non-viable or uneconomic options early, shortlist practical options, and define each shortlisted option to a comparable level of maturity for fair technical and economic evaluation.
- Develop the selected scheme to the depth required for Front End Engineering Design and, where required, support transition into Detailed Design, procurement support, construction planning, shutdown execution, commissioning and start-up.
- Technical and economic evaluation of options:

- Lead structured option evaluation covering safety, operability, constructability, maintainability, capital cost, operating cost, schedule, shutdown and turnaround impact, production value, risk, carbon / energy impact where relevant, procurement constraints, commissioning needs, start-up risk and implementation complexity.
- Work with estimators, planners and discipline leads to produce realistic option cost and schedule inputs appropriate to the study phase
- Prepare option selection reports, decision papers and recommendation packs suitable for senior management approval.
- Defend technical and commercial recommendations when challenged by client stakeholders, asset teams, reviewers and management committees.
- Governance, quality, assurance and decision defensibility:





- Ensure all study outputs are based on approved data, documented assumptions, clear exclusions, appropriate engineering standards and defined review cycles.
- Maintain decision traceability through assumptions, option screening criteria, risk registers, minutes, action close-out and client approval records
- Drive interdisciplinary reviews, technical checks, value reviews, hazard review preparation and management review readiness.
- Challenge weak discipline inputs, unsupported assumptions, optimistic schedules and hidden scope so that issues are closed before they become client, site or execution problems.
- Commercial, schedule and small-project control:

- Manage the study, small Front End Engineering Design, plant modification or small-project scope, budget, schedule, progress reporting, resource forecast and change control in line with Worley procedures and agreed client requirements.
- Recognise scope growth early and ensure additional work, review cycles, site visits, vendor support, data gaps or rework are raised through the correct change process.
- Support preparation of proposals, schedules, estimates, execution plans and technical qualifications for new studies and small projects.
- Ensure the delivery model is proportionate to the project value, avoiding unnecessary over-engineering while still protecting technicalquality, constructability, procurement readiness, commissioning readiness and Worley risk position.
- Procurement, shutdown, commissioning and start-up interface:

- Work with procurement teams to ensure study and Front End Engineering Design outputs define the right vendor packages, long-lead items, technical requisition inputs, enquiry support needs and vendor information requirements.
- Liaise with construction, com
