The building sector is under the significant influence of emerging technologies. Structures shape the environment and “consume” natural resources throughout their life cycle. They “live” many years after the construction which implies a dependence on some generations of supporting technologies. They can be useful in the subsequent phases: design, construction, maintenance and demolition. They may refer to main processes (construction production) as well as to concurrent processes (management, accountancy, logistics etc.). Computers, automated tools and machines or other intelligent devices seem to be inevitable in the 21st century. Therefore, contractors of construction projects should be sensitive to these issues. Based on literature studies, the article revealed that knowledge management in a construction company should primarily rely on the corporate culture that manifests a preference for computer-aided methods. This part was supplemented by a questionnaire technique and a statistical analysis of the results. It was concluded that the path to technological maturity of the construction company is a continual process. Consistency in this pursuit enables effective promotion of innovative technologies in the construction company. The research allowed us to draw three explicit phases: lack of experience, euphoria, and experience in becoming a technologically matured enterprise.

“…In natural resources, geofence alerts have been suggested as a way to monitor fishing activity near exclusive economic zones (EEZ) [ 26 ] and as an indicator of marine protection areas [ 27 ]. Licht et al described the use of geofences in real-time animal tracking [ 28 ] and Sheppard et al proposed the use of geofencing to reduce bird mortalities at wind farms [ 29 ].…”

Logging is one of the most hazardous occupations in the United States. Real-time positioning that uses global navigation satellite system (GNSS) technology paired with radio frequency transmission (GNSS-RF) has the potential to reduce fatal and non-fatal accidents on logging operations through the use of geofences that define safe work areas. Until recently, most geofences have been static boundaries. The aim of this study was to evaluate factors affecting mobile geofence accuracy in order to determine whether virtual safety zones around moving ground workers or equipment are a viable option for improving situational awareness on active timber sales. We evaluated the effects of walking pace, transmission interval, geofence radius, and intersection angle on geofence alert delay using a replicated field experiment. Simulation was then used to validate field results and calculate the proportion of GNSS error bearings resulting in early alerts. The interaction of geofence radius and intersection angle affected safety geofence alert delay in the field experiment. The most inaccurate alerts were negative, representing early warning. The magnitude of this effect was largest at the greatest intersection angles. Simulation analysis supported these field results and also showed that larger GNSS error corresponded to greater variability in alert delay. Increasing intersection angle resulted in a larger proportion of directional GNSS error that triggered incorrect, early warnings. Because the accuracy of geofence alerts varied greatly depending on GNSS error and angle of approach, geofencing for occupational safety is most appropriate for general situational awareness unless real-time correction methods to improve accuracy or higher quality GNSS-RF transponders are used.
