● Active use of smart technologies to boost productivity ●Unique construction sites: Promoting work style reforms● Establishing corporate structure to achieve sustainable innovation and human resource developmentConstruction work20Use of AI tools is expected to streamline and automate site ledgers nationwide and increase productivity.In anticipation of legal restrictions on working hours to be introduced in FY 2024, we plan to deploy Field Success Centers (FSCs) to improve work environments for site workers.Anticipating prospects of our organizations and human resources, we proactively promote young engineers to managerial posts to encourage them to play more active roles and to establish the future organizational foundation.Conventional casting (manual) Example of an AI toolComparison of manual concrete placement and automatic concrete compaction based on posture estimation technology (digital operation rendering)Client: Tokyo Metropolitan GovernmentThis work involves the new construction of distribution reservoirs, pump buildings, outdoor warehouses, and installation of interior piping facilities and pipework accessories at the water supply station located at 1-3, Umezono, Kiyose City, Tokyo, part of a water supply/distribution facility improvement project.AI-based posture estimationAutomatic compactingExample of sites where work has been completedTama North Water Supply Station (provisional name) construction project (Tokyo)Water gate civil engineering work for Class 2 River: Tashiro River Sujikawamukai area river disaster restoration (23 Disaster No. 661)Client: Iwate Prefectural GovernmentThis work involves the restoration and raising of the water gate (by about 5 m) and surrounding tide barriers of the Tashiro River, which sustained serious damage in the Great East Japan Earthquake. The site is in the Taro district, Miyako City, Iwate Prefecture. Amid the extreme scarcity of materials/equipment and labor immediately after the earthquake, we took flooding prevention measures in the area and completed the work in seven years and ten months. The project provides the area with strong protection against future tidal wave damage.
