KEYWORDS

  • BIM/CIM
  • Digital Twin
  • Construction Digital Transformation (DX)
  • Virtual/Augmented/Mixed Reality (VR/AR/MR)
  • Smart Infrastructure Sensing
  • AI
  • Smart Infrastructure and Buildings Using Advanced Information and Communication Technology

This project aims to develop a smart society framework that will dramatically improve productivity, usability, safety, economy, environmental performance, and landscapes in design, construction, operation, and maintenance.
The approach to achieving this objective involves the attachment of numerous IoT sensors to social infrastructure and buildings, and the use of a digital twin centred on 3D BIM (BIM/CIM) models, visualization, numerical analysis and simulation, and analysis by AI, as well as feedback and control to the real world.
In addition, research is being conducted on various disaster responses. The data models and methodologies developed are aimed at international standardization.

Research Introduction

Research objective

Solving various problems of productivity, usability, safety, economy, environmental performance, and landscape in the construction industry, where labor productivity is lower than in the manufacturing industry, by creating a digital twin using advanced ICT and applying it to design, construction, and operation and maintenance.

BIM modeling of existing buildings with integrated sensor data models and CFD analysis using IFC

Features

  • Technology for CFD analysis from an IFC-based BIM model generated from point cloud data of existing buildings measured with an iPad
  • Integrating sensor data models with an IFC-based BIM model and creating a BIM model for energy facilities.

Environmental impact assessment methodology for solar panels on highways using 6D BIM Models

Features

  • Accurate life cycle cost and GHG assessment technology for the installation of solar panels on highways.
  • An IFC-based 6D BIM model with time, cost, and GHG axes added to the 3D BIM model.
