“…The first step is an on-the-spot investigation in the observed area, determining the observation range and flight height, according to the observed building height, ground resolution etc. The second step is to assemble a UAV and prepare the flight plan on a sunny day, including camera exposure parameters and route parameters [39]. The third step is to conduct oblique photogrammetry at a fixed-point, based on the predetermined route.…”

Pedestrian space is an important place for people’s outdoor activities. Its thermal environment affects pedestrian walking experience, route selection and physical health. This study presents a 3D thermography-based method to analyze and evaluate the spatial distribution of thermal comfort. The proposed 3D thermal image was generated using 3D city models captured by an unmanned aerial vehicle (UAV) and thermal images gathered by an infrared camera. It can visualize construction elements, but also simply output surface temperatures at selected points. This paper described the process of using 3D thermal images to analyze the built environment, and selected two pedestrian spaces as case study objects. Their thermal images and mean radiant temperatures (MRT) were obtained from field measurement data collected by a drone and infrared camera. The following findings were obtained: (a) the MRT difference in the pedestrian space between sunlit and shaded areas was more than 3 °C; (b) the MRT values at the measurement points near vegetation were lower; (c) when the ratio of street height to width (H/W) was larger, the MRT values at all measurement points varied slightly. These findings can be used for the designers to evaluate and improve the thermal environment in pedestrian space.

“…With the deployment of UASs, site planners have become able to collect visual information to assist them plan construction activities and provide detailed schedule, layout, and logistics-related information, particularly when integrated with augmented reality (AR) (Wen and Kang 2014). Using UAS visualizations, a very recent analysis reconstructed a petrochemical plant to improve the hoist layout planning efficiency, ultimately resulting in faster, safer, and more efficient operations on the jobsites (Jiang et al 2020a). Based on several layout plans generated using a specific algorithm, the authors recommended an optimized and weighted site plan to improve hoisting operations' safety and efficiency.…”

Unmanned Aerial Systems (UASs) have rapidly been integrated into the construction industry over the past few years, and their application is continually growing in this domain. The recent development in UAS regulations and technical capabilities have played a significant role in their popularity and wide deployment in various stages of the construction lifecycle. UASs could be used as a platform to enhance the construction practices in general; however, little is known about how construction professionals are adopting this technology in specific construction practices and the barriers they are facing for their successful implementation. The purpose of this study is to explore the current state-of-practice of UAS integration in construction from the industry professionals’ viewpoint. A comprehensive survey study was conducted in the United States to identify the practical construction UAS application areas, their adopted technologies, as well as the benefits and barriers encountered during their implementation. Responses (n=56) showed that most common UAS applications include progress monitoring, site planning, and site surveying/mapping. Rotary-wing vehicles and visual and thermal cameras were the most used platforms and onboard sensors, respectively. Saving time, improving accessibility to compromised spaces, and reducing cost while accomplishing construction tasks were highly regarded as UAS implementation benefits in construction. Participants also considered flying in various weather conditions, within confined or congested areas, as well as the advanced technical know-how requirements, and the increased liability and legal challenges as barriers to using UASs in construction-related tasks. By understanding UAS adoption in construction, this study provides a roadmap to better identify the industry needs and guide researchers and professionals in investigating application areas and barriers that might have maximum benefits for the construction industry in the United States.

“…3D models can be called to design the construction frame, assess the feasibility of construction, and control project risks. If the building is particularly complex in shape, it is critical to eliminate risks before construction, thereby ensuring work progress and safety [49].…”

In petrochemical industry, the execution of construction involves three main issues, namely, design planning, construction, and job safety. Three-dimensional (3D) models are increasingly applied to design and construction. However, the improper concept of 3D design has bred potential unsatisfactory behaviors and the lack of vigilance among workers. Besides, many employees are not fully aware of the safety in 3D design and construction planning. Therefore, our goal is to improve the safety and health of construction workers through design practices in the upstream of the construction phase, and verify the applicability of the combination of 3D models and safety knowledge. Specifically, a questionnaire survey was carried out among 124 employees in the construction-related fields of the petrochemical industry. The collected data were processed, and statically analyzed on SPSS. The results show that safety knowledge was acceptable in 3D model design from the perspective of project executors, and the integration of safety knowledge into the design helps to improve the safety environment of the construction site.
