Digital Infrastructure Guide & Survey


Excavation Condition 3D Management App: Chika-Digi

In typical construction work, after excavation is completed, the underground condition is measured, and photographs are taken along with hand-drawn sketches.

This is a technology that can record excavation conditions as highly visible data by digitizing a video.
A device such as a smartphone or tablet can be used to record, upload, and submit the video to the web app to create 3D digital data.

The video is converted into 3D data using our company’s internal system and then resubmitted to the app.

The resubmitted data can come in various digital formats such as 3D modeling data, point cloud data, plan views, cross-sectional views, AR data, etc., and can be centrally managed using the map information platform GIS.

In addition, labor-saving nature of the work reduces working hours, thus improving labor conditions.

[Advantages and Usage]
*Only a smartphone or tablet is required.
*Data can be posted and viewed in the app.
*3D excavation results are intuitive.
*Depth, distance, etc. can be measured with the measurement tool.
*Centralized management is possible on the platform.
*Reduced working hours can lead to an improved work style.

Non-intrusive 3D exploration of underground objects


Non-intrusive 3D Exploration of Underground Objects

This technology integrates accurate 3D underground data of buried objects with 3D aboveground data of roads, buildings, etc. to create an underground visualization with high on-site reproducibility.

Typical buried object exploration only measures the cross section in the direction of travel, so little information is acquired.

With this technology, it is possible to acquire a large amount of information and by acquiring highly accurate 3D data of the underground by using multi-array antennas. By utilizing the acquired 3D data in all processes of design, adjustment, construction, and management, a safer and more efficient construction can be achieved by preventing rework.

Additionally, AR technology simplifies on-site work and reduces trial excavations.

[Advantages and Usage]
*3D maps can be output as CAD.
*Measurement of the distance, accuracy, height, and depth of objects is possible.
*Interference with existing buried pipes can be simulated.
*All concerned members can view the underground condition in three dimensions prior to construction.
*Underground information can be accurately updated by incorporating post-construction buried object conditions into a 3D map.

Bridge Deck Inspection


Bridge Deck Inspection

By utilizing quantitative evaluations based high-precision AI and image processing technology built on the knowledge of analysis accumulated to date, it is now possible for specialized engineers to analyze and make advanced determinations on floor slab health.

This quickly analyzes data, which is acquired at a maximum speed of 100km/h, and creates a diagnostic chart of the bridge deck and pavement interiors.

It helps to identify deteriorated parts of bridge decks and improves productivity in repair design and construction.

[Advantages and Usage]
*Early detection of deterioration inside pavement and bridge deck slabs is possible using microwaves.
*Data can be acquired at a maximum speed of 100km/h.
*Increasing cost effectiveness by promoted labor saving is possible.
*Centrally manage inspection data by creating a database.
