Kurimoto, Ltd. (head office: Osaka-shi, Osaka: representative: Kazutaka Kikumoto),
Photoruction, Inc. (head office: Chuo-ku, Tokyo; representative: Takaharu Nakajima) andMIRAIT Technologies Corporation (head office: Osaka-shi, Osaka; representative: YasushiTotake) will commence sales of the “Photoruction Water” “water pipe construction management
system using photoruction* (hereinafter referred to as the “System”) on April 20, 2021.
Water-supply corporations nationwide are entering a period when facilities constructed andinvested in during the period of high economic growth need to be updated at once while facedwith the difficult situation of revenue from water rates decreasing due to reduced water
demand. In particular, they are required to update and further strengthen the earthquake
resistance of aging pipe conduits accounting for much of the investment.
Even recently, the cabinet decision on “5-year Acceleration Measures for DisasterPrevention, Disaster Mitigation and National Resilience” made in December 2020, sets targetsof raising the percentage of earthquake-resistant core pipe conduits from 40.3% in FY2018 to
60% in FY2028, requiring the pace of earthquake resistance work to be increased.
However, both the public sector and private sector are having difficulty securing engineersand passing along skills, and the improvement of productivity and operational efficiency are
significant issues for the continuity of operations. To address this situation, the City of Kobe
Waterworks Bureau and four private-sector companies jointly conducted research on a “Water
Pipe Construction Management System Using Photoruction” to improve efficiency andautomate water pipe construction management operations utilizing knowledge on waterworks
infrastructure and ICT.
The “Photoruction Water” system developed through the joint research is a construction
management application be used on sites specializing in water pipe construction, improving

efficiency spanning from records of on-site operations to the creation of forms to be delivered tolocal governments.
The efficiency of preparation of documents that has previous been carried out at night or on
holidays after on-site work is carried out can be improved because the iron pipes to be installed
can be selected on and joint checks can be performed on a mobile device while on site.
It supports multiple types of iron pipes such as GX type and NS type, and can output to forms
such as the pipework journal and joint check sheet.
The System will support the improvement of productivity of water-supply corporations andwater-service works companies nationwide with the aim of improving the efficiency of waterpipe construction work.

productivity and quality.
