Efficient on-site data collection is important for ensuring timely information flow and successful project management. Although applying information technologies and electronic devices to reduce time-consuming manual paperwork has been valued, one previous study has indicated that asynchronous operations with unnecessary subprocesses still affect information production and transmission. Implementing synchronization-based processes is a solution to enhancing on-site data collection performance. However, these synchronized processes based on worker cooperation still have room to improve their efficiency. Continuous improvement is essential to satisfying this objective. This study thus develops a synchronous system integrated with wireless and speech technologies to enhance the cooperation between construction workers and application devices. System tests and efficiency evaluation in a material management case study demonstrate that this system increased productivity, reduced operation time and simplified subprocesses for activity completion. The synchronous system not only represents a novel application for on-site material management, but also provides a framework for applying wireless and speech technologies for similar on-site information management.

Comprehending activity status is essential to successful project management. When construction workers report activity information, project managers understand activity progresses. This procedure forms information exchange and flow. However, the lack of up-to-date information still causes project problems (such as increasing unnecessary costs, making erroneous decisions and improper activity scheduling), and highlights the importance of on-site data collection. For improving this condition, this study integrates two managerial philosophies ("theory of constraints (TOC)" and lean construction) to propose a synchronization-based model. When this model was applied for a material management case study, asynchronous operations accompanied with unnecessary subprocesses were recognized as an influence on on-site information production and transmission. This study then applied synchronous operations based on worker cooperation to resolve these problems, and evaluated the efficiency obtained by the identified measurements. The proposed model offers not only a prototype of synchronous on-site data collection, but also a mechanism for activity performance improvement. (C) 2006 Elsevier B.V. All rights reserved.
