Testing Bar‐Code Technology in Construction Environment

Construction management, like management in other industries, relies on data that can be processed into information. In the information age, many mature technologies provide management with a variety of options for accessing data quickly and reliably. Bar‐code technology is one option receiving more and more attention in general from the construction industry. Since bar codes are now rarely used in construction, knowledge about their applicability in this industry is sparse and lacks any scientific background. In particular, the question of the survivability of bar‐code labels in the construction environment has never been investigated. This paper presents testing methods for bar‐code labels and adhesives that have been specifically developed for the conditions of construction sites. Results of laboratory and field experiments using the testing procedures will be evaluated as a basis for general recommendations. Also presented are data input concepts developed for a specific application. The encouraging results of the research effort suggest that bar‐code technology is indeed ready for use in construction.
