7. ConclusionDrone technology is observed to contribute to increasing productivity in many areas at construction sites. Applications show that this technology facilitates many activities, from planning to monitoring construction work, from increasing occupational health and safety to monitoring infrastructures, making it more efficient and less costly.While drones facilitate the creation of expensive and time-consuming topographic maps, especially for large construction sites, they also minimize human errors. This saves time and money while creating the maps and prevents possible major negative deviations that occur in the project budget and duration that is caused due to outdated or incorrect maps. One of the most important elements of project management is real-time monitoring of the construction site and timely response to events so that the project is completed within the prescribed budget and time. One of the biggest benefits of drones is that they facilitate progress monitoring in the site and make it efficient. One of the most studied issues in the literature is the effect of drone use on occupational health and safety. Studies have shown that drones are effective tools for monitoring the workers whether they comply with occupational health and safety rules. While drones make monitoring various infrastructures, especially bridges and railways, easier and more efficient, they eliminate both human-induced errors in these activities and the security risks that appear while monitoring the infrastructure with traditional methods. Drone technology is also crucial in detecting damages due to disasters such as earthquakes and floods and taking necessary precautions quickly and effectively. Apart from these, studies indicated that drones could be used in many other applications, such as ensuring the maintenance of the construruction site, taking precautions related to traffic during road constructions and ensuring construction site safety.All these make construction management easier, more effective and more efficient while making companies using this technology more competitive. Moreover, with the developing technology, drones' application areas are expected to expand much more. Although there are various obstacles to using this technology, which is relatively new, these obstacles are easily overcome with the development of technology and adaptation of the sector to technology.In conclusion, it could be stated that it is important for construction companies and managers to adopt drone technology to their construction sites to make their operations more efficient. However, being careful in the procurement of drones, which are more technological than other equipment used in construction sites, is important. Another important issue to be considered is that the regulation on using drones. Knowing the related regulations is important since drones pose security risks as they may fall during flight and since people's privacy may be violated due to aerial surveillance of drones. This review study indicated that using drones in construction sites will be beneficial, especially in completing the construction projects within the determined budget and time. In this respect, sector stakeholders should adopt this technology to their construction sites without hesitation, which will make their company more competitive and ready for the future.This study only focused on the non-technical aspects of drone technologies. However, the technical aspects of drones should also be discussed in future studies as stakeholders' decisions on the usage of drones might be affected by these aspects
