Smart Technologies for Modular Construction: A Review Of Current Applications

Abstract

Modular construction has been around for a while, but it has been limited in its application. Recently, it has gained momentum due to the emergence of smart technologies that address technical and management challenges, enhance quality and safety, and save time and money. This study reviews and highlights the existing smart technologies used in modular construction throughout a modular project’s lifecycle to understand the application areas, benefits, impediments, and research regarding smart technologies in the modular construction field. The review involved a three-step procedure for selecting smart technologies applicable to the modular construction industry. First, a list of smart technologies related to modular construction was selected from the Modular Building Institute’s industrial magazines and from the Autodesk company site. Second, a literature review was conducted using specific keywords. Finally, articles were screened based on relevance. The smart technologies identified include blockchain, computer vision, digital twin, generative design, VR, 4D BIM schedule, and robotic arms. The findings will help researchers and practitioners interested in modular construction to 1) better understand how smart technologies are used and help modular construction and 2) further use or develop them to improve the modular construction industry sector.
