EPC工程科技创效应用指南（2020版）中国建筑第二工程局有限公司ChinaConstructionSecondEngineeringBureauCo.Ltd

前言为积极响应中建集团“一创五强”战略目标，围绕局“五大突破，六大提升”的要求，提升全局的科技创效能力，推动局高质量发展，局编制了《科技创效应用指南（2020版）》系列图册。图册分为房建工程、公路工程、地铁工程、EPC工程、机电工程、钢结构工程、装饰装修工程、文化旅游类工程和核电工程等九个分册，每个分册由设计优化、施工优化、科技成果转化和实用新技术四大部分组成，旨在为一线工程技术人员提供有益的创效参考。请图册使用者根据工程特点灵活运用。能达到举一反三、抛砖引玉之效果亦是编撰者之初心。《科技创效应用指南（2020版）》系列图册主要由西南公司、土木公司、华北公司、三公司、安装公司、华东公司、装饰公司、核电公司编制完成，局专家委员会做了最后的审查，在此一并表示感谢。随着科技创效工作的深入推进，相信会有更多、更好的创效做法不断涌现。希望广大工程技术人员及时收集、整理并反馈给我们，以便《科技创效应用指南》及时更新。二〇二〇年九月

第一部分、设计优化一、投标阶段优化7

投标阶段优化合同优化实施/优化效果：方便EPC项目设计费结算，早期回收项目成本适用范围：所有EPC项目1.目前大多数EPC项目合同中只约定项目总承包费用，支付也是根据项目进度支付
