PLANNING AND ENGINEERING Planning and Engineering involve the development and evaluation of possible options that then culminate in a front-end engineering report and concept. Options may include traditional network solutions such as asset replacement or renewal, accepting the risks of service level breach (do nothing), new technology solutions (e.g. distributed generation, batteries etc.), non-asset solutions or combinations of these options. Each option is developed and a preferred option selected based on the option’s economic value, technical feasibility, risk, strategic alignment and on asset management policy considerations including sustainability. Safety in Design forms a critical part of this stage of the asset investment process and is a mandatory consideration that requires collaboration with stakeholders. Where an asset solution is recommended, functional and performance requirements are specified, lifecycle management plans are developed and a project scope is prepared as the basis of the Design and Construct stage. Where appropriate, we also assess non-traditional solution options which may include distributed generation and batteries to meet the functional or performance requirements expected and a combination of options may be developed to address a particular requirement. Where a non-asset solution is recommended, appropriate specialist processes are engaged to progress the response 3 . In some cases, where no technically or economically feasible option is identified, the front-end engineering design may lead to a revaluation of the identified need. DESIGN AND CONSTRUCT During the Design and Construct stage, Vector translates the selected option into a project scope, functional requirements and performance requirements, a set of design specifications and design drawings. In accordance with our asset management policy, life-cycle cost minimisation is undertaken during design to ensure that ownership and acquisition costs are minimised. Vector also undertakes assessment of safety, constructability, standards compliance, reliability (i.e. failure modes effects analysis), design standardisation, sustainability, environmental impact and operability during design to ensure that assets can be safely and effectively maintained and operated across the lifecycle. In addition, design is undertaken to align with relevant corporate and asset management strategies. The outputs of the design process are detailed technical design documentation that is used to guide procurement and construction. During design, essential information is captured in Vector’s system of record to enable and support the ongoing management of our assets. Asset Support forms a further essential part of the Design and Construct stage and provides key links with the Programme Delivery stage. Drawing on service level gap and root cause analysis undertaken in the Needs Management stage, Asset Support develops detailed plans for maintenance, spares holding, data systems, finance and resources that maintain asset performance across the lifecycle. All assets are reviewed annually and a comprehensive set of plans are produced that set priorities to maintain asset performance against the required service levels. These plans are approved under our governance practices before being programmed and delivered by the FSPs. PROGRAMME DELIVERY Programme Delivery is a process that involves asset acquisition, construction and commissioning, operations, maintenance and disposal. Construct and Dispose links Design and Construct with Programme Delivery. Through this process, the detailed design documentation produced is translated into network assets. Construction of new assets, testing and verification of “as built” assets and disposal of old assets is undertaken through the Construct and Dispose process to ensure compliance with design documentation, and Vector’s standards (see Section 7, Appendix 2). Critical asset data records are created or updated in Vector’s systems of record during this process. Under our governance practices, approval of the preferred option is required prior to proceeding to the Design and Construct stage or prior to referral to a specialist non-asset solution process.

3 The nature of the process for non-asset solutions, and some new technology solutions tends to be bespoke and highly dependent on the type of solution recommended. These are not addressed further in this AMP.
