摘要

价值管理(VM)和价值工程(VE)是有关定义、最大化和实现“物有所值”的技术。值得注意的是,虚拟机不是关于降低成本,而是关于增加价值,并且在必要时可以增加成本以实现价值。尽管这种做法在从有限的资源中获得最大产出方面已被证明具有重要意义,但在卢旺达的建筑工业中并不是一种普遍做法。因此,本研究定义了虚拟机,并描述了其中涉及的所有过程和技术。详细讨论了VM工艺在建筑项目中的优点和缺点,并考虑到项目的范围和复杂性以及所涉及的风险,讨论和推荐了其使用的相关性。虽然价值管理审查的好处经常被认为是提高了质量和降低了成本,但本报告讨论了作为衡量价值的功能机制的实践,考虑到货币和非货币利益,从而证明了金钱的价值。虽然作者未能获得卢旺达VM实践的相关文献,但通过对相关文献的回顾可以推断,发展中国家对建设项目进行的大多数评估技术主要依赖于对项目在成本、质量、交付和进度方面的绩效进行评估。由于项目评估是在工作完成后进行的,因此分析的输出将只是给客户一个指示或对项目绩效的良好理解。这样的评估只能揭示项目参与者的能力或无能,而不是提供物有所值,这是由VM实践解决的,这是一种考虑所有价值参数的事前分析。本研究采用定量调查研究方法,从卢旺达建筑业的专业从业人员那里获得反馈。调查样本为115名建造业专业从业员,当中有106名成员作出回应。最后,得出卢旺达建筑业不采用VM方法的结论,并建议卢旺达建筑业采用VM做法,将其作为预算在2000万美元及以上的所有建筑项目的概念的强制性要求。

Application of Value Management in Conception of Construction Projects in Rwanda
Value Management (VM) and Value Engineering (VE) are techniques concerned with defining, maximizing and achieving “value for money”. It should be noted that VM is not about reducing the cost but about adding value and where necessary the cost can be added to achieve value. Despite its proven significance in securing maximum output from limited resources, this approach is not a common practice in Rwanda’s construction Industry. This study therefore defines VM and describes all the processes and techniques involved in it. The merits and demerits of VM process in construction projects are discussed in details and relevance of its uses is discussed and recommended in consideration of the scope and complexity of the projects as well as the risks involved. While the benefits of a value management review are often perceived in terms of improved quality and reduced cost, this report discusses the exercise as a functional mechanism to measure value, taking into account monetary and non-monetary benefits and thus demonstrating value for money. While the author has not been able to obtain relevant literature on VM practice in Rwanda, It can be deduced from the review of the related literature that most of the evaluation techniques conducted for construction projects in developing world have mostly relied on evaluation of project performance in terms of cost, quality, delivery and progress. Since project evaluation is carried out after the work has been undertaken, the output of the analysis will just give the client an indication or a good understanding of the project performance. Such evaluations only reveal the competence or incompetence of the project participants instead of providing value for money which is addressed by VM practice which is an ex-ante analysis that takes into consideration of all value parameters. The study used a quantitative survey method of research to obtain responses from professional practitioners in construction industry in Rwanda. The sample size of 115 were selected from members of professional practitioners in the construction industry out of which 106 members were responsive. Finally, it is concluded that VM approach is not used in construction industry in Rwanda and recommended that VM practice be adopted in construction industry in Rwanda as a mandatory requirement for conception of all construction projects with a budget of $20M and above.
