For decades, reputation of the construction industry has been tainted by poor cost performance caused by project cost overrun. In addition, studies by scholars worldwide have also found cost overrun to be more serious in developing countries compared to the developed countries. Despite the numerous researches addressing the issue of cost overrun in the construction industry through the years, the issue remains. Acknowledging that maintaining good cost performance is a key factor of project success and that the issue has persisted for decades, this study aims to explore the distinction of cost overrun studies that has been conducted between developed nations and developing nations. In achieving this aim, a systematic literature review is performed by following the integrative steps of PSALSAR (Protocol, Search, Appraisal, Synthesis, Analysis and Report) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) for screening and selecting the retrieved studies. The synthesis and screening of literatures have yielded with 152 articles which are then classified into their countries, developed countries (44) and developing countries (108). The results indicated a significant difference in the domain of research on cost overrun between the 2 nations. Despite the numerous studies on cost overrun in the developing nations compared to developed nations, the majority of the studies are not directed to any specific type construction while developed nations have moved forward to focus on more specific projects. The project with the highest attention in the developed nations is transport infrastructure construction projects, particularly rail infrastructure projects. The findings of this study have shown that there have been broad studies conducted on cost overrun in both developing nations and developed nations. However, there is a slight lacking in comprehensiveness of cost overrun studies in the developing nations, perhaps future studies on cost overrun in developing nations can be directed to more specific areas of construction projects such as those that have been performed by researchers of the developed nations.

“…Their cost estimate is mainly to provide a preliminary estimate for selecting a suitable contractor through a competitive bidding for construction. Kavuma et al [10] had identified the cost overrun risks in free-form projects. Most of them were closely related to free-form panel fabrication such as lack of project-specific customization of fabrication technologies, poorly defined project scope at the time of budgeting, inappropriate subcontractor selection for free-form facades, mistakes in quantities and cost estimate, and unclear specification or scope of work.…”

“…According to previous research, among the three types of the curved panels, the double-curved panel is very difficult to form, showing bigger quality discrepancy than the other two panel types, which makes free-form projects overall very complex, often harming their geometrical beauty [10]. While comprehensive research is necessary for supporting small/mid-scale contractors to understand the methods of measuring as-built quality of the curved panel, the behavior of each panel type, the limit of the panel materials, and the proper production methods for the materials, thereby enhancing their project quality management capacity, most of the research in the area of free-form buildings has focused on mass and rapid panel production with cutting edge CNC-based technologies and the geometric design of the curved façade with meagre insight into small free-form buildings [11].…”

Constructing free-form buildings is very complex due to the difficulty in fabricating the curved façade. To install the façade, the complex geometric shapes of the façade need to be divided into panels. The panels developed are classified into three categories in terms of their curvatures, i.e., planar, single-curved, double-curved panels. The quality of the curved façade is determined by the geometric difference between as-built and as-designed panel shapes. Among the three types of curved panels, the double-curved panel is very difficult to form, showing greater quality discrepancy than the other two panel types. Ensuring the as-built quality of the curved façade is for contractors. The main objective of this study is to enhance small/mid-size contractors’ capacity of managing the as-built quality of the double-curved panel. To meet the study objectives, a case study of a small free-form building and empirical mock-up tests of curved panels were performed and beneficial lessons for the contractors were identified through the tests. Among diverse materials, aluminum and glass-fiber-reinforced concrete (GFRC) were utilized for the mock-up tests. Three-dimensional laser scanning technology was employed to foster the as-built data of the case study project and the mocked-up double-curved panels. The data superimposition method was used to measure the deviation between the as-designed and the as-built data of the case study.

“…The technique is applied to solve CPS constraints via team collaboration (Alsehaimi et al, 2014;Daniel et al, 2017;Kovvuri et al, 2016); -CPS planning and management: CPS planning and controlling of CPS has been examined. For instance, early project planning is the basis of CPS (Al Nas-seri & Aulin, 2016; Larsen et al, 2018) and schedule monitoring using control charts (Băncescu, 2016); -Factors affecting schedule: CPS Labour productivity (Huang et al, 2014), resources (Larsen et al, 2016), labour and personal issues, risks and uncertainties (Kavuma et al, 2019) are examined by previous studies as they are problems affecting project schedule; and -Time-cost-trade-off: Time-cost trade-off has been one of the most CPS research areas focusing on reduction of project duration with an optimal cost. For example, schedule compression using fast-tracking (i.e., overlapping of activities) for both linear and nonlinear projects (Ballesteros-Pérez et al, 2019) and crashing (Sonmez et al, 2016).…”

Scheduling plays a fundamental role in construction projects’ success and thus has drawn attention from both academic researchers and industry practitioners. A large number of research articles tend to solve emerging challenges in construction project schedule (CPS). Therefore, there is a strong need of systematic review on existing studies. In this study, a total of 332 articles were retrieved from Scopus database using title, abstract and keywords with respect to CPS and filtered by document type, language type and abstract content. In particular, science mapping approach was adopted to analyse selected journal articles. These articles were examined using three sequential processes, including bibliometric search, scientometric analysis, and in-depth qualitative discussion. It could demonstrate the most influential journals, researchers, published articles, and active countries/regions in this area. In addition, major CPS knowledge areas were identified and summarized as CPS constructability, applications of variety of CPS methods, CPS optimization models and algorithms, identification and quantification of schedule risks and uncertainties, CPS performance management, and adopting new emerging CPS technologies and methods. Furthermore, knowledge gaps and future potential research directions were also discussed in detail. Finally, a comprehensive CPS framework was proposed as a sound reference in future research.
