Construction trends in 2020 will focus on increased use of smart technology like IoT, BIM, and drones to improve efficiency and safety. Prefabricated and modular construction will grow due to cost reductions from standardized assembly off-site. Collaboration tools and the cloud will help connect office and site teams to share project information. Robotics, AI, and blockchain will also impact the industry by automating tasks and securely tracking supply chain data. Sustainability practices like green building materials will become more important.
