A review of current practice in constructability improvement: case studies on construction projects in Indonesia

The concept of constructability emerged in the late 1970s, evolved from studies into how improvement can be achieved to increase cost efficiency and quality in the construction industry. It is an approach that links the design and construction processes. The studies in the USA, UK and, later, in Australia have demonstrated that improved constructability has lead to significant savings in both cost and time required for completing construction projects. However, in implementing constructability improvement, it is important to consider the uniqueness of the construction industry in a specific country. To improve constructability in Indonesian construction projects, two main questions need to be answered: how is construction integrated into planning and design in existing practice and how can constructability be improved. Case studies indicate that the contractual relationships between the project team members determine the options for early involvement of construction personnel, and that the current constructability practices have had some positive impacts on project performance. In addition to a reduction in constructability problems, current constructability practices have enabled significant economic savings.     

Project affinity: the role of emotional attachment in construction projects

Although a wide range of human and organizational factors have been found to be important in the operation of projects, those determined by cultural variables are less well defined. One such influence concerns the notion of ‘project affinity’, the commitment and attachment by stakeholders and participants to projects and their outcomes. The temporal nature and transient involvement context provided by construction projects arguably presents a climate in which many participants are less likely to display commitment to its goals. This note is concerned with the issue of whether an attachment to a project's goals or to the completed product can lead to improved commitment among those involved. The concept of project affinity was developed in the course of a case study investigation in which operatives' attitudes towards the construction of a cancer research facility were explored. Because of the contribution of the facility to the future care of cancer sufferers, the concept of project affinity proved helpful in understanding a factor that appeared to be influencing the commitment of those involved. The results suggest a complementary concept to that of ‘project chemistry’ (c.f. Nicolini, 2002 Nicolini, D. 2002. In search of ‘project chemistry’.. Construction Management and Economics, 20: 167–77.  ).     

治理对公共项目管理绩效改善的实证研究——以企业型代建项目为例

通过文献综述可知,公共项目管理绩效改善有管理和治理两大途径,前者显而易见,已得到学术界和实务界的普遍认可,而后者一直以来都被默认为是成立的而没有得到任何证实。首先借鉴产业组织理论的SCP范式,提出关于公共项目治理、管理、管理绩效3个变量之间路径的基本假设,并构建实证研究模型。而后,运用结构方程模型方法对60个企业型代建项目的数据进行统计分析,研究结果表明,公共项目治理通过管理间接贡献于公共项目管理绩效。最后,通过对研究结果的分析得出公共项目管理绩效改善的一种基本思路,即GMP分析框架,从而证实了治理确为公共项目管理绩效改善的重要途径。

基于治理的政府投资项目代建制绩效改善研究

政府投资项目在我国经济生活中发挥着重要作用。在政府投资项目行政代理制度下,项目管理绩效不高,导致项目绩效也不佳。国内推行的政府投资项目代建制管理模式就是针对行政代理制度下的弊端展开的一项改革措施。研究围绕国内推行的代建制改革是否有效,如何改善代建制绩效而展开。在项目治理的新范式和研究框架下,探讨了不同时期我国政府投资项目治理模式演变和企业型代建制下的项目所有权配置,建立了相应的代建制治理水平初步评价指标,在此基础上从制度层面对政府投资项目代建方案进行了设计。研究结果表明,我国代建制发展方向为企业型代建,对该代建模式下所形成的治理结构的改善需要通过内部治理和外部治理以及政府监督机制等三个途径实现。

建设项目动态联盟收益分配改进研究

随着建筑市场竞争激烈程度日益提高,动态联盟这一新型的组织模式已经成为建筑伙伴企业追求自身发展壮大并获得竞争优势的重要战略,而建立伙伴间合理的收益分配机制又是保证建设项目动态联盟高效运转的关键要素。盟主企业通过设计正式契约引入激励机制,以提高伙伴的努力水平,从而保证联盟的稳定运行和项目目标的实现,联盟收益分配对象由盟主和合作伙伴共同确定,业主以及项目利益相关者对项目价值的认可也应作为联盟收益分配的对象。针对以联盟确定的伙伴努力水平所实现的收益为收益分配对象的不公正性,根据建设项目动态联盟的实际情况,建立以联盟、业主、项目利益相关者等确定的伙伴最终实现的项目价值为收益分配对象的模型,并通过对伙伴所完成分包项目价值状态的确认,确定一个奖励额度,实现对正式契约和模型的改进,采用遗传算法对模型进行求解,算例结果表明,改进后的模型极大地提高了伙伴的努力程度,提高了收益分配的合理性。

Critical path effect based delay analysis method for construction projects

Assessing schedule delay's impact on total project duration to distribute delay liability remains a controversy. None of existing delay analysis methods is perfect because including an element of assumptions, subjective assessment and theoretical projection. Windows-based delay analysis methods are excellent in identifying and measuring construction schedule delays. Based on a previous study identifying potential problems in available windows-based delay analysis methods, this study proposes an innovative windows-based delay analysis method, called the effect-based delay analysis method (the EDAM method). The EDAM method performs delay analysis using extracted windows and determines delay impacts by considering the effects of delays on the critical path(s). According to its application to hypothetical cases and comparisons with other methods, the EDAM method is efficient in delay analysis and effective in solving concurrent delays and determining schedule shortened. The proposed EDAM method is a good alternative for schedule delay analysis for construction projects.

The role of multi-firm satisfaction in construction project success

Construction project success depends on the multi-firm project organizations involved working together satisfactorily. Yet, satisfaction within multi-firm relationships has rarely been examined as a determinant of construction project success. A pioneering study is carried out to evaluate the extent to which construction project participants’ perception of each other’s performance reflects on the owner’s perception of project success. The data represent 580 performance evaluations carried out among the project owners, project consultants, main contractors and designers. The owner-evaluated performance factors related to the project goals form a dependent variable called Project Success. Dependencies between Project Success and the various performance factors are identified based on Pearson’s correlation coefficients. Dependencies were discovered between Project Success and all owner-related relationships and all but one of the non-owner-related relationships. Preliminary sets of discipline-specific and evaluator-specific success factors are identified. The results support the proposition that satisfaction within both owner-related and non-owner-related relationships is reflected on success. Therefore, researchers and practitioners are encouraged to consider project success in terms of multi-firm satisfaction and to engage with multi-firm performance measurement to better understand the heterogeneous performance factors contributing to multi-firm project success.
