Overview
"Geological and geotechnical risk" refers to the invisible "uncertainties" inside the ground that may cause cave-ins, sinkhole accidents, ground subsidence, etc., during underground
excavation and other similar work.
Through 3D visualization of geotechnical and geological structures, 3D geological analysis technology is a solution for reducing uncertainty and preventing accidents and disasters
caused by geological and ground factors.
OYO Group proposes geological and geotechnical risk management with the aim of increasing productivity throughout the entire construction and production process. Specifically, we
engage in measures such as extracting geological and ground risks from the business planning stage, promoting risk communication from the stages of survey, design, construction, and
maintenance management, optimizing business costs, and preventing construction delays.
Features
Geological risk management provided by the OYO Corporation
Preliminary risk assumptions and management methods proposals based on geological expertise
We evaluate the terrain and geology of candidate sites from the business planning stage, and propose the necessary risk communication methods and management plans.
Using 3D technology to visualize geological risk, also linked to BIM / CIM
Using the latest 3D geotechnical analysis technology to visualize hidden geological and geotechnical risks. We propose appropriate countermeasures that are neither excessive nor deficient. We also link our technology with BIM / CIM for building 3D geological models.
Creation of a management chart that assumes multifaceted risks. Proposals for monitoring
Based on the assumed geological features, we organize risks that may occur in the succession process and methods for dealing with those risks. If there is residual risk, we propose appropriate monitoring methods.
By having expert geological engineers extract geological risks at the applicable site from the initial phase of business planning, OYO Group is able to increase productivity throughout the entire construction and production process. Specifically, we enable smooth risk communication from the stages of survey, design, construction, and maintenance management, optimization of business costs, and prevention of construction delays.
