可行性研究支持

环资公司专业从事项目范围定义,预可行性研究、详细可行性研究。这些服务通常包括:资源定义研究管理,采掘计划,冶金测试和流程制定,设计工程,资本和运营成本估算,环保规范,项目控制及审计和审查。随着可行性研究的完成,相关的服务还有关键交付事项的审查可评估,如资本和运营成本,研究报告等。

环资公司的研究管理业务通过公司项目管理系统应用为项目发展提供阶段性的方案。这种方法包括三个可行性研究阶段,两个项目执行阶段和一个总结阶段。下面的图表对其进行了更为详细的说明。

Assess

During the project Assess phase, the business opportunity is evaluated at a high level. Project criteria and objectives are developed for key components with major resource definition activities initiated. The key objective of this stage of the project development life cycle is to confirm the attractiveness of the opportunity prior to committing further funding. The level of detail is in line with the accuracy, veracity and confidence required for the decision to proceed to the Select phase (typically +/- 30 to 60%).

Select

During the project Select phase, project criteria and objectives are reaffirmed and an increased level of project detail is assessed. Resource definition continues targeting the next level of detail and sufficient engineering is conducted to allow selection of the preferred project configuration case. A key objective from this stage is the identification of a preferred project configuration that maximises the value of the business opportunity. The level of detail is in line with the accuracy, veracity and confidence required for the decision to proceed to the Develop phase (typically +/- 15 to 30%).

Develop

The Develop phase is the last stage of the feasibility study assessment process. During this phase, the selected configuration case from the Select phase is studied in much greater detail to achieve sufficient accuracy in resource definition, approvals, costs and schedule to secure project funding. The level of assessment ensures no fatal flaws and that significant risk are identitied and mitigation strategies established for implementation during the project execution stage. The level of detail is in the with the accuracy, veracity and confidence required for the decision to proceed the the Execute Stage (typically +/- 10 to 15%).

Detail Verificaton

Upon approved of the Detailed Feasibility Study which forms the basis of the project development, the project enters a Verification phase. The purposa of this phase is to ensure the enginear responsible for project execution conducts a final review to ensure no omissions or fatal flaws exist in the design, capital and operating cost estimates and schedule that will cause the project to exceed the level of accuracy estimated i.e. +/- 10 to 15%. The Verification phase is not considered an opportunity to significantly change project scope (unless a fatal flaw), as these changes will in most circumstances increase costs and time, requiring both the budget and schedule to be updated and reissued as the basis of project control. Clearly, defining the Scope of Work during the Develop phase is critical.

Execute

As the project enters the Execution phase, a significant increase in egineering acivity occurs. Design is translated into vendor packages for final cost assessment and procurement and detailed engineering and planning commence to ensure site activities proceed according to the approved shedule.

Close-out

The final phase of the project life cycle involves closure of any remaining project development activities as the project moves into an operations function. Activities include finalisation of facility drawings, contract claims, archives handover to operations, any final plant modifications and project team demobilisation.

注意细节在项目生命周期的三个研究阶段(评估,选择和制定)至关重要,这可以保证最佳的决策以及制定的方案获得审批和融资。未能完成这种选择分析将导致优化效果的降低,因为这样会越来越难将重大的项目范围变更进一步纳入项目周期,除非增加延误项目进度的潜在风险和项目的成本。这种对细节的关注是获得可预见的项目成果的基础,也是我们固有的公司文化和精神特质。
