Purpose: The existing literature has been mainly focused on local problems but without an overall framework for studying the top-level planning of intelligent construction from a systematic perspective. The purpose of this paper is to fill this gap. Design/methodology/approach: This research adopts a deductive research approach. Findings: This research proposes a reference architecture and related business scenario framework for intelligent construction based on the existing theory and industrial practice. Originality/value: The main contribution of this research is to provide a useful reference to the Chinese government and industry for formulating digital transformation strategies, as well as suggests meaningful future research directions in the construction industry.

Purpose: The purpose of this paper is to assess the process of prefabricated construction (PC) and analyze the impacts of rework risk to identify the core tasks for which the rework risk has severe impacts. Design/methodology/approach: The methods consist of a literature review, expert interviews, a questionnaire survey and a rework risk function. The expert interviews and questionnaire survey were administered to experts in the entire process of PC from the dimensions of rework frequency, rework cost and rework time. Descriptive and inferential statistics were employed to analyze the data. The rework risk function was based on the loss expectancy method. Findings: There are 13 core tasks that have higher impacts than the average level. The core tasks in the design stage account for 100% of the tasks in the stage, those in the manufacturing stage account for 20% and those in the construction stage account for 23.1%. Compared with the other stages, the design stage is characterized by significantly more frequent rework, higher rework costs and longer rework time. The manufacturing stage is characterized by significantly higher rework costs than the construction stage. The manufacturing stage and construction stage are co-reliant, and both are impacted by the design stage. Practical implications: The findings provide stakeholders with a clear understanding of the core tasks of the PC process and represent a method for identifying core tasks. Stakeholders can learn from this to focus on the core tasks to reduce rework risk and manage the process with the priority of PC rework management based on the following order: design > manufacturing > construction. The approach is suitable for core task identification in other areas. Originality/value: This research provides insight into rework risk management and provides a novel analysis method for rework risk and PC management from the perspective of the construction process. The findings are valuable for supporting stakeholders in making effective construction plans to reduce the impacts of rework risk in PC and provide a reference for future research on process optimization.

Purpose - The paper aims to focus on institutional initiatives to embed e-learning in a university in Hong Kong, from 2006-12, through large-scale funding of 43 e-learning projects. It outlines the guiding principles behind the university's e-learning development and discusses the significance of various procedures and practices in project planning, development and implementation. Design/methodology/approach - This longitudinal study combines historical perspectives with process description, analysis and personal observations. Its approach is based in action research. The authors are engaged both as participants/learning designers in particular projects and in management, administration and evaluation of the projects at the institutional level. Findings - It is proposed that e-learning projects need careful planning, scaffolding and managing. Also that piloting, evaluation and formal reporting as well as the availability of professional, technical and instructional design support are significant factors in success. Research limitations/implications - This paper is preliminary work. Further findings and analysis are expected at the final completion of all projects. A wealth of data is available in accumulated project documentation and reports, including individual project evaluations with quantitative and qualitative data. Originality/value - Given the commonly acknowledged difficulties in helping e-learning projects continue to completion and actually be implemented, this study can offer strategies that may be widely applied in different contexts. The scale and timeframe of the study and the amount of funding available in one institution are unusual so emerging implications are potentially significant. [ABSTRACT FROM AUTHOR]
