In the construction projects, it is necessary to conduct subsurface exploration at every stage of planning, design, and construction.
We select the most suitable methods according to the site conditions and objectives of surveys and investigations, and perform the subsurface exploration for the purposes of understanding the ground where structures are to be constructed and the effects on groundwater, and studying the necessary measures to prevent disasters.
We carry out borehole drilling surveys, field tests, and laboratory soil tests to obtain the ground information (ground strength, groundwater, etc.) necessary for the design and construction of roads, tunnels, bridges, rivers, and erosion and sediment control facilities.
We also perform geophysical exploration to investigate the geological conditions and structures by measuring physical properties such as elastic wave velocity and electrical resistivity of the ground.
Hydrological survey is carried out to understand the effects of the construction work on the surrounding groundwater environment.
Specifically, we observe well water levels and stream water quantity at each stage before, during, and after construction and conduct water quality analysis in order to determine the effects of construction, examine alternative water sources, and provide data of compensation for business losses.

We identify the geotechnical engineering issues based on geological reconnaissance surveys, borehole drilling investigations, and soil tests. Thereafter, we conduct ground stability, deformation, and settlement analysis to ensure safe design and construction.
To obtain an overview of the topography, geology, and ground conditions of the survey area, our professional engineers who has extensive knowledge and experience observe the topography, outcrops, boulders, etc., create a route map, and compile it into a geological map.
In geotechnical analysis, we carry out appropriate simulation of various issues including settlement of soft ground, study of liquefaction at seismic times, stability of slopes and landslides, and groundwater flow. Based on the simulation, we predict and evaluate the impacts of these issues, and ensure optimum design and construction.
