The record heavy rains in September of 2015 (mainly in the Kanto/Tohoku areas), where over 200m of the embankment on the Kinugawa River collapsed, around a third of the city of Joso (40km2) was completely flooded out, and in Ibaraki prefecture where more than 5,000 homes were destroyed is still fresh in my memory.
In the Kinugawa river basin, the “Kinugawa Response Project” was opened, and on the hardware side, embankment maintenance, leakage countermeasures, river channel excavation etc. were carried out.
“H28 (2016) Excavation work on the upper river section of the Mitsukaido Ohashi Bridge” was a project that KIMURA KOUGYO Co., Ltd worked on – not as a project for i-Construction – however it was a job that the company decided to bid on as an i-construction project, and was given the work accordingly.
Hitachi Construction Machinery conducted groundwork surveying and conducted support for the company in each work flow area. Hitachi Construction Machinery ‘s ICT solution is to maximize the use of the customers’ know – how and to optimize methods through collaborative team work.
“I am very happy cooperating with Hitachi Construction Machinery as we move forward. For this work site, we asked HCM to carry out the surveying of the groundwork etc. using UAV (drone applications) and 3D point cloud data. We did the design and work planning etc. in-house using 3D data creation, but even here we were given great advice as well. The machinery and the accompanying ICT was also all rented from HCM. This has made it possible to decrease the work time required, lessen the staffing model by between six to eight workers, and not need a 20m pitch stake as would have been necessary on past conventional projects.
There are companies that just entrust all of their information construction needs to a construction consulting company, however “In addition to the fact that there is too much work placed on the site managing agent, any additional requests for sudden design changes etc. from the customer/supplier can sometimes be too much for them to handle. For KIMURA KOUGYO, we believe in being the ‘Prime contractor’ with anywhere from 1-10 staff depending on the work involved being engaged in the project in order to keep a firm control on the work involved. The HCM ICT solution looks like it should be able to respond well to these important points with great detail, and therefore I would like use HCM support from now on.”
