i-Construction Systems Lab
Machine-translated · View original
An endowed lab that uses ICT and robotics to raise productivity at construction sites.
AboutAbout the lab
Raising construction productivity with the latest technology
The i-Construction Systems Lab researches systems that use information and communication technology and robotics to raise productivity in construction.
The lab aims to bring technologies such as AI, IoT, blockchain, and 5G communications into the construction industry.
Civil Engineering and Precision Engineering work as one in the lab, which carries out research with researchers accepted from a wide range of industries.
The lab also works on developing educational systems to train engineers who can make full use of the systems it develops.
Key terms
- i-Construction
- A national initiative that makes full use of ICT (information and communication technology) at construction sites, aiming for accurate and efficient construction
- Blockchain
- A technology that manages records such as transactions by sharing them across many computers, making them hard to alter
- Hammering sound inspection
- An inspection method in which tunnels, bridges, and other structures are struck with a hammer and defects are found from the sound

ResearchResearch themes
The lab develops systems that realize "i-Construction," which raises productivity by bringing IT, IoT, spatial information processing, robotics, and other technologies into the whole process of social infrastructure, from planning and surveying through to maintenance and operation. Civil Engineering and Precision Engineering work as one, and the lab carries out research together with researchers from a wide range of industries.
*Illustrative imageUsing infrastructure data
The lab is developing a platform that connects information across construction, from conceptual planning through design, construction, and maintenance. It is also building a prototype of an integrated evaluation system so that data on social infrastructure can be used in many different ways.
*Illustrative imageNew construction methods with robots
Using robotics and sensing, the lab studies new mechanisms for construction and inspection, including remote operation of construction machinery, unmanned construction, automated hammering sound inspection, and robotic inspection of infrastructure.
*Illustrative imageSharing information with blockchain
The lab is developing a blockchain-based supply chain management system that streamlines information sharing and procedures among companies in different roles, such as project owners, general contractors, specialty subcontractors, and suppliers of materials and equipment.
*Illustrative imageHow construction is run, and its institutions
The lab studies how construction should be run and how its institutions should be designed, through work such as designing institutions for construction production and management systems, institutions for developing technologies that support higher productivity, and analyzing the causes of changes in construction work.
