ABSTRACT With the spread of networking and computing technologies, ubiquitous computing is a concept attracting increasing attention in industrial development and innovation. In this study, a mass concrete curing management system (CMS) is introduced to investigate the possibility of applying ubiquitous computing to jobsite project execution. The proposed CMS consists of three parts—wireless data acquisition, strength estimation, and an alarm. A case study is performed to validate the CMS in the mat foundation of a high-rise building construction. This system will allow the project engineers or managers to make timely decisions about the cooling operation of the pipe cooling system, which removes hydration heat from the concrete with embedded cooling pipes in the structure, and about the timing of formwork stripping. This suggests that the productivity and efficiency of construction management can be improved by adopting a ubiquitous computing environment in construction.

    ABSTRACT: Purpose – The purpose of this paper is to develop a model for the use of mobile computing in the management of on-site construction information and communication. Design/methodology/approach – The research strategy contains three steps: a pilot study for the first stage, a survey that investigated the information needs of particular users and the nature of on-site information, and finally the development of a model and the validation and evaluation by operational scenarios. Findings – The developed model explores how mobile computing can be used on construction sites to manage on-site information. This model, firstly, identifies the key factors of mobile computer, wireless network, mobile application, construction personnel, construction information, and construction site; secondly it describes the relationships and interactions among these factors. Based on the model, the selection process for mobile computing strategy includes the clarification of information management process, the creations of overview for mobile computing solution, the identification of mobile computing strategy, and the selection of appropriate mobile computing technology. Originality/value – The developed model explores the general concepts and the internal relationships at the two areas of mobile computing and construction site information management. The application of the model can help users to select mobile computing strategies for managing on-site construction information based on the characteristics of their projects.
