Advanced Construction Technology Center (ACTEC) was established in 1989.
ACTEC aims to develop advanced construction technology and disseminate it in construction sites for practical use. We continue to make an effort toward technology development in order to improve infrastructures for safety and prosperity of the nation. |
・ACTEC is authorized by Ministry of Land, Infrastructure and Transport(MLIT),
Government of Japan.
・ACTEC is consulting the projects of MLIT and the local governments.
・ACTEC is the think tank in the field of infrastructure, such as rivers, roads. |
