摘要

大多数大型项目未能实现其目标。研究表明,多达三分之二的项目没有达到时间、成本或性能目标,这一比例远高于传统项目。失败的原因多种多样:利益相关者的偏见、缺乏对前端规划的投资以及乐观的估计和/或时间表等因素。此外,很明显,业主越来越需要在压缩的时间范围内进行更大、更复杂的项目。然而,即使经验表明目标不切实际,也几乎总是有承包商愿意为这项工作提供竞争性投标。尽管最近管理能力有所提高,采购和承包做法、风险评估、项目规划和控制也有所加强,但大多数大型项目的成果几乎没有明显改善。本文基于作者在大型项目方面的学术和行业经验,并对交付大型项目的合同背景提供了另一种看法,以及这如何影响目前扩大合同和程序的做法,试图为大型项目提供与传统项目类似的确定性。事实上,现有的合同惯例可能会阻碍采用更适当的交付方法。参考Jobling PE和Smith NJ(2018)合同在大型项目执行中的作用经验。土木工程师学会会刊——管理、采购和法律171(1):18-24,https://doi.org/10.1680/jmapl.17.00006.帕克曼奖章获得者Paul Jobling(中)和Nigel Smith(右)与ICE主席Andrew Wyllie于[02/04/20]由[]下载。版权所有©ICE出版,保留所有权利。

Award-winning paper in 2018
The majority of megaprojects fail to achieve their objectives. Studies suggest that up to two-thirds of them do not meet time, cost or performance targets, a much higher proportion than that for conventional projects. Failures are attributed to various causes: stakeholder biases, lack of investment in front-end planning and optimistic estimates and/or schedules, among other factors. Further, it is evident that owners increasingly require larger, more complex projects within compressed timescales. However, even if experience shows that the objectives are unrealistic, there is almost invariably a contractor that is willing to provide a competitive tender for the work. Despite recent improvements in management capability and enhancements to procurement and contracting practices, risk assessment, project planning and control, there has been little noticeable improvement in the outcomes of most megaprojects. This paper, based on both authors’ academic and industrial experiences of megaprojects, focuses on another factor, the contract, and provides an alternative view of the contractual context in which megaprojects are to be delivered and how this affects the current practice of scaling up contracts and procedures in an attempt to offer megaprojects levels of certainty similar to those of traditional projects. Indeed, the existing contracting practice may act to militate against the adoption of more appropriate delivery approaches.
