SERVICE 01

Tunnel Design

We cover the full process for road and rail tunnels — preliminary and detailed design, stability review, and support for on-site design revisions. Drawing on NATM and TBM expertise, we propose tunnel sections optimised for the ground conditions and carry out precise stability assessment through 3D numerical analysis.

BIM Design

Using specialist BIM software including Revit, ABIES, HTB and OFS, we deliver 3D modeling, quantity take-off and simulation. BIM models built specifically for civil and tunnel work raise design accuracy and minimise construction errors.

Earth Retaining Design

We provide earth retaining and ancillary civil design suited to a wide range of sites — new-build projects, logistics centres and residential developments. Optimal methods are selected against site conditions and verified through stability review to support safe construction.

Underground Safety Assessment

Under the Special Act on Underground Safety Management, we conduct small- and large-scale underground safety assessments, reassessments, and post-commencement surveys — covering groundwater impact analysis, ground stability review and settlement prediction.

SERVICE 05

Post-Commencement Underground Safety Survey

Under the Special Act on Underground Safety Management, we carry out underground safety surveys after excavation work has begun — tracking changes in the ground and surrounding facilities and analysing monitoring data to confirm safety.

SERVICE 06

Underground Safety Assurance

When temporary works plans or construction staging change, we prepare the corresponding underground safety assurance plan — reviewing groundwater drawdown and ground stability through three-dimensional numerical analysis, and proposing reinforcement measures so that construction can continue safely.

Stability Review & Numerical Analysis

We assess the impact of new construction on adjacent structures — subways, tunnels and shafts — through three-dimensional numerical analysis. Modeling that predicts the extent of fracture zones supports case-by-case analysis, followed by displacement cause analysis and reinforcement proposals.

Ground & Hydrogeological Investigation

We carry out a broad range of ground and hydrogeological investigations — borehole surveys, deep drilling, groundwater studies and hydraulic modeling with Visual MODFLOW. In-house equipment and hydrogeology specialists deliver precise, reliable data.
