ENGINEERING MANAGEMENT Identification Selection Definition Execution Develop engineering to sufficient detail to enable a Class 4 or 5 capital estimate to be prepared for the alternative. Use benchmarking, information and order of magnitude estimating. Leverage off existing information to support the capital estimate. Prepare Class 2 estimate for selection phase engineering activities. Develop an engineering work plan for inclusion in the overall selection phase SWP. Advance engineering in accordance with the SWP covering all scope aspects (mine, infrastructure, and processing facilities). Develop engineering for the alternatives to sufficient detail to enable Class 4 or 5 estimate and schedule. Develop the basis of design (BoD) for the selected option.

Develop the engineering strategy to be adopted for the definition and execution phases of the project.. Commence application of value improving practices (VIPs) consistent with the value improvement plan. Advance engineering in accordance with the SWP covering all scope aspects. Finalise the BoD for the selected alternative. Review the Pre- Commitment Funding Class 2 schedule from selection phase, finalise and baseline for reporting and control Develop engineering for the selected alternative to sufficient detail to enable a Class 2 capital estimate and Class 2 schedule. Advance development of engineering technical deliverables to enable procurement of precommitment items (e.g. technical specifications and data sheets). Continue to apply VIPs to further optimise the selected alternative. Develop the engineering management plan for the execution phase. Prepare a Class 2 estimate for the execution phase engineering activities. Establish the basis for the engineering controls system. Implement the engineering management plan. Complete detail engineering in accordance with the approved scope of work, BoD and project technical specifications.
Identification Selection Definition Execution Prepare tender documentation to enable selection and award of the implementation contractor for the definition / execution phases of the project. Prepare Class 2 estimate and Class 2 schedule for definition phase engineering activities. Prepare Class 2 schedule for Pre- Commitment Funding planned for execution during definition phase Develop an engineering work plan for inclusion in the overall definition phase SWP including provision for detail engineering of any precommitments. Engineering management strategy To develop the engineering management strategy: The most appropriate engineering strategy depends upon what investment phase the project is in, the complexity of the project and the scale of the project. For the majority of projects, the engineering strategy during the identification and selection phases is different to that implemented during the definition and execution phases. Continuity of engineering input through project phases is important and subject to satisfactory performance against pre-determined acceptance criteria, the implementation contractor appointed for the definition phase continues to the end of the execution phase. For larger projects, it is preferable to appoint an implementation contractor with the requisite experience and capability to undertake the procurement and construction management activities. Value engineering centres are effective in cost reduction, provided that interface management, battery limit complexity and communication are properly addressed.

Study phase engineering Identification Phase Study Identification phase activities include: Identify major alternatives for evaluation in the selection phase. Identify all potential material issues or major risks. Define what work needs to be done to further assess the investment opportunity. Plan for the next phase i.e. the SWP for the selection phase, defined deliverables and budget hours. Engineering is required to support these objectives with key considerations as follows: Develop engineering to enable an order of magnitude estimate to be completed. Use highly experienced personnel. Leverage off recent project data for similar facilities or infrastructure developments. Selection Phase Study The engineering activities for the selection phase include: Complete preliminary engineering to support Class 4/5 estimates and schedule on alternatives identified and short listed during the selection phase. This information is critical to the opportunity framing and opportunity selection process. Develop the overall engineering strategy, consistent with the overall project execution strategy. This includes the strategy to be adopted for both the definition and execution phases. Develop the BoD for the selected alternative. Finalise the location study for the project. Prepare a preliminary plan for carrying out detailed engineering in the execution phase.
Definition Phase Study Best practice level of engineering progress at the estimate cut-off stage of the definition phase study meets the following minimum requirements: Layout drawings are frozen. BFDs, PFDs and P&IDs are at issue for design stage. BoD is complete. The engineering scope of services is fully understood and captured in a Class 2 schedule. There is formal approval by project and operations teams. The SWP for the definition phase engineering, which is prepared at the end of the selection phase, includes both engineering activities for the definition phase and engineering planning activities for the execution phase: The engineering activities for the definition phase include: Progress the design and develop the deliverables to enable development of a Class 2 capital estimate and Class 2 schedule, appropriate for a definition phase study and sufficient for project control purposes during the execution phase. Commence detailed design for any long lead items that have been identified. The schedule is critical to identify these items. The BoD must consider: Relevant site conditions, e.g. topographical, seismological and climatic data. Operability, reliability and maintainability of the processing facility. Design life for the facility and key components. Safety parameters identified and provided for in the design e.g. preliminary HAZOP and HAZAN. Occupational health issues identified and provided for in the design basis. Environmental constraints to be placed on the processing facility identified and provided for in the design basis. Design criteria for each discipline i.e. process, mechanical, civil, structural, piping, electrical and instrumentation. Off-site conditions that are likely to be reflected in supply or product transportation logistics constraints provided for in the design basis. Identification of the parties proposed to be responsible for providing and performing engineering, the standards to be adopted, the engineering role of the project team, quality assurance, HAZOPs and technical / expertise issues. The inclusion in the engineering plan of CAD tools and associated workflows, data acquisition - in particular vendor and brownfield site data, quality assurance and control methods, document control / approvals, design office / site office interaction and detailing. Ensure that engineering firms have the requisite tools in place (CAD, management control systems, etc.) prior to commencement of engineering.
