Implementation and Control of Wireless Data Collection on Construction Sites

A mobile site level data collection system has been implemented for piling works utilising the IEEE 802.11b wireless protocol. The system, used by dedicated ‘pile managers’ and the workforce, allows for realtime data collection and storage into a site-based server, via a mobile wireless local area network (WLAN). The use of a WLAN allows for easy access and manipulation of timely construction data to assist in the management of the project, enhancing information flow throughout the site, reducing remedial costs and improving contract performance. This paper discusses the implementation of the WLAN on two construction sites, difficulties encountered, benefits and recommendations for further work, together with user perspectives. A cost-benefit analysis also suggests a substantial saving on remedial works can be made with the introduction of site-based data capture.
