Construction site monitoring by the usage of digital technologies

Tema ovoga diplomskog rada je pregled stanja razvoja i dostignuća tehnologija za digitalnu kontrolu i monitoring gradilišta. U prvome dijelu rada opisano je što je monitoring, koje su uobičajene metode monitoringa te koja je trenutno postojeća i razvijajuća oprema odnosno alati za monitoring. Nadalje, opisane su razvijajuće tehnike monitoringa te modeli i planovi čije je spajanje s rezultatima monitoringa spomenuto u slijedećem poglavlju. U drugom dijelu rada provedena je studija slučaja na gradilištu parkirališta ispred zgrade Fakulteta elektrotehnike, računarstva i informacijskih tehnologija Osijek. Studija slučaja provedena je snimanjem gradilišta koje je trajalo ukupno 21 dan, a izvršeno je bespilotnom letjelicom (dronom) DJI Mavic 2 Zoom. Podaci dobiveni snimanjem uneseni su u računalni program MS Excel te je nakon statističke analize rezultata prikupljenih podataka monitoringom napravljena usporedba stvarnog učinka radnih strojeva bagera i valjka s njihovim teorijskim i planskim učincima. Usporedbom stvarnog učinka navedenih radnih strojeva došlo se do zaključka da je njihov stvarni učinak veći od proračunom dobivenog teorijskog i planskog učinka, no iznenađujući iznosom bliži teorijskom nego planskom učinku.The topic of this thesis is the development and achievements of technologies for digital control and monitoring of construction sites. The first part of the thesis defines the term and scope of monitoring in general. Furthermore, the common monitoring methods and current and developing equipment and monitoring tools, the developing monitoring techniques, as well as models and plans whose connection with the monitoring results were presented. In the second part of the paper, digital monitoring was applied in a small-scale case study construction project. The case study construction project included monitoring the parking lot construction site in front of the building of the Faculty of Electrical Engineering, Computing and Information Technology in Osijek. The case study digital monitoring, by a DJI Mavic 2 Zoom drone, of the construction site, lasted for 21 days out of 30 days of total project's duration. The data collected by the monitoring were then exported into an MS Excel document for statistical analysis. Upon collected data and theoretical background, the comparison of the actual performance of excavator and roller machines with their theoretical and planned efficiency was made. Comparing the actual performance of these working machines, it was concluded that their actual performance is surprisingly and significantly higher than the calculated theoretical and planned performance. Furthermore, the results showed that the actual performance is mathematically closer to the theoretical than anticipated planned machines' performance
