Construction extension: 125m Digging: 5,300m² Earth Retaining wall work: 668m³
ICT Solution used:
ZX200X-6 (3DMC), UAV surveying, 3D point cloud processing, 3D design data creation, UAV work quality management
National Highway No. 439 General Grant Project for Social Capital Development (Kochi Pref., Susaki Civil Engineering Office)One of the important arterial roads in the city. Construction of two lanes for Route No. 439Went to an on-site workshop as the first ICT utilization project for the Kochi prefecture.
Background of introduction
The construction work using ICT at Takahashi Construction is the first work on this site.
An evaluation on the on-site-support system was carried out between Fuji Co., Ltd – a measurement device company in the Kochi Prefecture – and HCM Japan, which resulted in a decision to for us acquire a 3DMC hydraulic excavator.
“Although there is the inevitably cost up front in the initial investment, the system does have its merits. We have also purchased software to help with handwritten drawings so that we can convert them into digital based electronic delivery using 3D data. Although the investment can never be recovered from just one site, it can be depreciated as it is used in other areas, and as the system adds to our own knowledge base, I would like to pro-actively engage in ICT work going forward.”
Using the software of for a construction system, Mr. Takahashi was able create his 3D design data. UAV photo surveying & point cloud processing was conducted in cooperation with Aratani Civil Engineering Consultants co., Ltd.
Results and Future Prospects
“ICT utilization construction was never a difficult option. The regulations and standards involved with projects can also be handled within the software settings. For shaping cut surfaces and excavation for foundations, it was able to reduce surveying and it demonstrated its effectiveness more than our original expectations.. Once we got used to it, there we realized that there is no other option as easy as this.”
“The hard-coarse drilling and finishing modes of this machine control is really convenient. Work efficiency is improved by using the application according to the site requirements. Slightly slower for finishing surfaces, but moves as expected. Normally you don’t need that much speed on road surface sections.”
“Machine control is not suitable for all work on sites such as stabbing, but it is our job to keep working on improving ways to work at the site such as understanding machine performance and utilizing 3D data. I’d like to try various other work such as more difficult base digging, step cutting and other work types in the future.” (He says with great enthusiasm)
Takahashi Construction will continue to actively develop ICT construction and move forward with its development in the future.
