Digital twin and its applications in the construction industry: A state-of-art systematic review

Abstract

The construction industry has a great impact on social and economic development because of its wide coverage and a large number of stakeholders involved. It is precisely owing to its large volume that technological innovation of the construction industry is relatively slow. The birth and rapid development of digital twins brings more hope to the construction industry. This paper summarizes the current development of digital twin and its applications in construction industry. First, the concepts and applications of digital twin are analyzed. Then, the research on digital twins in the construction industry in the past five years is reviewed. The main research directions and key technologies are pointed out in the end. This paper could guide related practitioners to clearly grasp the research application status of digital twin in the construction industry. It could also help to find suitable research directions.

Analysis of Modern Types of Control of Construction Works and Problems of Their Development

“…«Твердым ядром» представлений о цифровой модели строительного объекта следует считать положения о создании его «цифрового двойника» (основой такого двойника как раз и является BIM). Хотя строительство отстает от многих других отраслей в этой сфере, постепенно исследования такого рода появляются, в них достаточно часто упоминается съемка с беспилотных воздушных судов (БВС) как источник информации для двойника [33]. В целом к наиболее распространенным способам формирования информационного массива по объекту строительства относят лазерное сканирование, данные геоинформационных систем, компьютерное зрение, умные сенсоры, Интернет вещей, идентификацию по RFID-меткам и др.…”

Automation of monitoring construction works based on laser scanning from unmanned aerial vehicles

“…Thus, in modern conditions, the expediency of using unmanned aerial vehicles (UAV) for conducting aerial photography of construction sites and obtaining the necessary information has already been established [11]. For example, in [12], the problem of monitoring the state of ground heating networks was solved on the basis of thermal imaging from the UAV, which makes it possible to identify the places of coolant leaks that require repair.…”
