电网建设投资审批程序及设计人员应注意事项

Approval Procedure of Power Grid Construction Investment and Design Personnel Attentions

电网建设投资审批程序主要是可研估算核准、概算批准、竣工结算三个阶段,前阶段的批准的投资额对后阶段有限制作用。可研核准、初步设计概算批准这两个阶段要经过设计文件上报、审查、收口、复核、批准等复杂过程。这些过程和不同阶段审核,主要是为使电网工程造价合理确定和有效控制,促进优化设计和降低工程造价。设计人员应注意主要是:可研阶段结合工程条件适当考虑裕度;初步设计阶段优化设计从而控制和降低工程造价,对概算超可研要分情况分别处理;工代竣工结算要从紧从严出设计变更单和签证工程联系单及如何处理与相关方可能发生的费用纠纷。强调收口设计提资对确定造价的重要性,指出技术指标合理性分析这一设计文件对投资审查及审批通过的作用。

The procedure for approval of power grid construction investment is mainly composed of three stages：Checking of feasibility study estimate,approval of preliminary design estimate ,settlement of work completion. The approved investment of the former stage limits the latter one. The 1st and 2nd stage need to go through complex progresses：Document Reporting,inspection,estimate closing,re-checking,approval and etc. These progresses and inspection for different stages is mainly in order to reasonably certain and effectively control the power grid construction investment,promote the optimization design and reduce construction cost. The designer should mainly attention these points：in the feasibility study stage—considering margin properly connected with engineering specifications; in preliminary design stage —optimizating design to reduce and control construction cost ,treat in different ways to different cases if preliminary design estimate breakthrough the feasibility Study estimate; In the feasibility study stage —strictly bringing out design change notice and project contract notice,how to deal with expenses dissension with interested parties. The design material of estimate closing should be emphasized because it is important to the following：Certain the construction cost; Reasonable analysis of technical target as a necessary document for get through investment approval successfully.
