Geological Survey: "Laboratory Soil Tests and Rock Tests"

Geological Survey: "Laboratory Soil Tests and Rock Tests"

We also accommodate special tests outside of JIS and JGS standards! We provide the data that our customers need.

At Kyoa Development, we conduct "Indoor Soil Testing and Rock Testing," where we perform laboratory tests on soil and rock samples collected on-site to evaluate the physical, chemical, strength, and deformation characteristics of the ground. The "Indoor Soil Testing" is carried out using sampling materials (undisturbed samples and disturbed samples) to understand the physical and mechanical properties of the ground. Additionally, we accommodate special tests that are not covered by JIS or JGS standards, providing the data that our clients require. Our testing centers are located in two places: Kanto (Chiba City, Chiba Prefecture) and Kansai (Sakai City, Osaka Prefecture), and we also welcome clients to attend the tests. 【Features】 ■ Indoor testing ■ Support for special tests beyond JIS and JGS standards ■ Provision of data required by clients ■ Attendance at tests is also supported *For more details, please refer to the PDF materials or feel free to contact us.

Geological survey

Geological survey

We propose survey methods and plans that are suitable for your objectives and current situation in the field of geological surveys. *Over 60 years of experience.

At Kyoa Development Co., Ltd., we propose survey methods and plans that are suited to your objectives and current situation, including simulations and consulting in the field of geological surveys. Our engineers visit the site to observe the topography and geological conditions, starting with "surface geological surveys," and conduct investigations such as "boring surveys" and "in-situ tests." During the surveys and tests, we provide situation reports (interim reports) as needed, and we continuously share information with our clients to facilitate discussions on changes to the survey/test content or additional tests based on the circumstances. 【Features】 ■ Proposing suitable geological survey plans based on over 60 years of experience ■ Guaranteeing highly reliable geological surveys and tests ■ Providing detailed reports for situation understanding and smart progress management *For more details, please refer to the PDF materials or feel free to contact us.

Geological Survey "Surface Geological Survey"

Geological Survey "Surface Geological Survey"

Engineers will observe the topography and geological conditions! We will investigate the characteristics of the ground and bedrock.

At Kōa Development, engineers visit the site to observe the topography and geological conditions, conducting a "surface geological survey" to investigate the characteristics of the ground and bedrock. This survey is conducted to understand the geological properties, engineering properties, and hydraulic characteristics of the foundation ground in the target area, and to estimate and clarify the formation of the topography and geology, as well as the geological structure, based on their planar and spatial distribution. The data from the surface geological survey plays an important role in the interpretation of results from boring surveys and physical exploration. 【Features】 ■ Engineers visit the site to observe the topography and geological conditions ■ Investigation of the characteristics of the ground and bedrock *For more details, please refer to the PDF document or feel free to contact us.

Geological survey "Boring survey"

Geological survey "Boring survey"

We provide all the ground information you need! We investigate the geological layers of the ground using a boring machine.

"Boring surveys" are the most fundamental method of geological investigation. By using a boring machine to excavate and observe the collected samples, the composition of the strata can be understood. Generally, a standard penetration test is conducted during excavation to measure the N value (an indicator of the relative density and hardness of the ground). Our company plans and proposes sampling during boring, as well as various tests and investigations utilizing the borehole, as needed, providing all the ground information required by our customers. 【Features】 ■ Understanding of strata composition ■ Investigation of ground strata composition using a boring machine ■ Provision of all ground information required by customers *For more details, please refer to the PDF document or feel free to contact us.

Geological Survey "In-Situ Testing"

Geological Survey "In-Situ Testing"

Understand ground characteristics in situ! Conduct tests in the original position to investigate the properties of the ground.

At Kyoa Development, we conduct "in-situ tests" to understand ground characteristics at the site. Since tests can be performed in situ, we obtain data that is not affected by factors such as confining pressure and sampling disturbance, compared to methods that involve collecting soil samples and conducting laboratory tests. We provide appropriate planning and execution of in-situ tests according to the purpose and target ground. 【Features】 ■ Investigation to understand ground characteristics in situ ■ Data obtained is not affected by confining pressure and sampling disturbances ■ We provide appropriate planning and execution of in-situ tests according to the purpose and target ground *For more details, please refer to the PDF document or feel free to contact us.

Geological Survey "Field Measurement"

Geological Survey "Field Measurement"

We will measure groundwater levels, ground subsidence, structural deformation, vibrations, and noise!

At Kyoa Development, we conduct "on-site measurements" to assess ground conditions, groundwater levels, and structural deformations at the site. Depending on the purpose, measurements may be conducted over the long term and continuously, in which case we may employ methods such as automatic measurements. We also customize measurement equipment according to the purpose, target, required accuracy, and measurement duration. We provide on-site measurements tailored to our customers' needs. 【Features】 ■ Measure ground conditions, groundwater levels, and structural deformations on-site ■ Customize measurement equipment according to purpose, target, required accuracy, and measurement duration ■ Provide on-site measurements tailored to customer needs *For more details, please refer to the PDF document or feel free to contact us.
