Digital Twin for Construction and Logistics for Lego-Inspired Construction
This project is a part of “a Block of Cubes”. The overall theme is “Digital Lego-Inspired Construction”, which aims to transform the way we build.
Overall Theme: To meet climate change, labor shortage, and construction productivity challenges, we propose a new civil infrastructure construction scheme borrowing ideas from Lego-toys. High quality damage-tolerant bricks will be designed and 3D printed in highly automated factories, tagged and inventoried in distributed warehouses, selectively retrieved (based on information from digitized architectural or structural designs) and transported to construction sites and assembled into structures using computer vision aided robots. At end of life of the structure (e.g. a building), the structure will be disassembled robotically, and the individual bricks will move to another construction site and reconfigured into a different structure (e.g. a bridge) or return to inventory. If embedded sensors detect deterioration, the damaged brick will be rerouted to a factory for refurbishing before being inventoried. The emphasis will be on construction automation and digitization, and complete brick/material reuse and carbon sequestration, through creating rapidly joinable bricks. Novel financial, supply chain, and logistic models as well as new legal framework are anticipated for this unconventional construction paradigm. Please see the attached Figure.
This Specific Cube: This cube intends to create digital twin for construction and logistics as a backbone of Lego-inspired construction. Given that the bricks can be aware of their status with sensors, a digital replica of a whole construction and logistics process will be created to better understand and control this automation process. In addition, machine learning and artificial intelligence techniques will be used to automate decision making on a near real-time basis for smooth delivery of a project. Further, with the help of BIM, GIS, and computer vision, all will be visualized and thus, what-if scenarios can be simulated and visualized before they are implemented.
