At the awarding ceremony of the “Infrastructure DX Awards” hosted by the Ministry of Land,
Infrastructure and Transport (MLIT) on March 17, 2023, Toyo Construction Co., Ltd.
(President and Representative Director: Kyoji Takezawa) was awarded the Award for Excellence
for the “Quay (-14m) construction work at Tsuruga Port (southern Maruyama area) (No. 3)”
completed in FY 2021 by our Hokuriku branch.
We were awarded the prize because of the following three reasons.
● In the construction of the quay wall, etc., we saved the manpower of 3 workers
(approx. 28%) and shortened the construction period by approx. 2 hours per box,
by using the “Box-navi”, a caisson installation system to visualize the location and
movement of caissons in real time as well as by visualizing and automating
the water feed/discharge control.
● The approach improved the safety as well as efficiency by utilizing the ICT technology,
which resulted in reducing the leveling work by divers by 26% with the visualization of
rubble deposition by introducing the Injection Location Guidance System utilizing the GNSS
and with the heavy weight compaction by using the Construction Management System utilizing
the 360-degree VR images.
● Since utilization of the installation of deformed concrete caissons with an asymmetric structure
has been implemented and further improvements, including the utilization of other company’s
technologies according to site conditions, are anticipated in the future, ripple effects are expected.
MLIT began the i-Construction Awards in FY 2017, and changed the name to the “Infrastructure DX Awards”
in FY 2022, expanding the eligibility to include efforts for non-construction industry such as utilization of
infrastructure or improvement of services, in addition to efforts for productivity improvement at construction sites.
Mr. Tetsuo Saito, Minister of MLIT, praised the efforts of award winners saying, “This is the realization of DX
in the infrastructure area.” at the award ceremony. As MLIT designates 2023 as the “breakthrough year”
to further accelerate the transformation by the DX, the Company will focus more fully on the DX to
contribute to the improvement of industry-wide productivity and safety.
