中国情境下工程总承包单位设计优化动力不足的影响因素与对策

Factors Influencing Insufficient Motivation for Design Optimization by EPC Contractors in the Chinese Context and the Countermeasures Thereof

工程总承包模式是一种先进的工程交易模式,设计优化效果是顺利推行总承包模式的主要动力之一。总承包单位设计优化动力不足引起了业界和学界的高度关注,如何在中国情境下提高设计优化动力是摆在业主和总承包单位面前亟待解决的问题。为此,首先分析总承包单位设计优化动力不足的影响因素,然后从风险分摊、收益分配、控制方式、总包能力、投标规则、配套规则、示范文本及典型示例角度,提出相应的对策。研究结果表明:中国情境下总承包单位开展设计优化是可行的,但有关各方需要采取相应的对策。研究成果为政府部门发布示范文本和典型示例以及业主、总承包单位开展设计优化工作提供参考。

The Engineering,Procurement,and Construction(EPC) model is an advanced project delivery method,and the effectiveness of design optimization is a key driver for its successful implementation.The insufficient motivation for design optimization among EPC contractors has garnered significant attention from both industry and academia.Addressing how to enhance this motivation within the Chinese context is an urgent issue for both owners and EPC contractors.This study first analyzes the factors influencing the lack of motivation for design optimization among EPC contractors.Subsequently,countermeasures are proposed from perspectives including risk sharing,benefit distribution,control mechanisms,EPC contractor capabilities,bidding rules,supporting regulations,standard texts,and typical examples.The findings indicate that design optimization by EPC contractors in the Chinese context is feasible,but it requires appropriate countermeasures from all relevant parties.The results provide references for government departments in issuing standard texts and typical examples,as well as for owners and EPC contractors in conducting design optimization work.
