Automatically generating geological models for civil engineering
Establishment of safe and stable underground construction plan through accurate ground status prediction
It is a self-developed solution that can automatically calculate the BIM model and quantity of geology, soil barriers, and files required for civil engineering work by using the information on the thickness of the borehole, thickness of the strata of the ground survey. Through rapid and accurate production, the reliability of the civil engineering process plan can be secured by performing multiple construction simulations. It takes 1 day/person to create the BIM model, and it takes 2 days/person to calculate the quantity.

Real-time auto-calculation of RC volume by construction zoning
Establishment of a zoning plan for the construction of reasonable frame construction (RC) considering the amount of pouring per day.
In order for the frame work (RC) BIM to be effective in the field, the amount of zoning by zoning according to the amount of work (remicon) and the construction joint (C.J.) structure should be calculated by structure member. The system can calculate the amount of zoning plan that changes in real-time in Excel when the construction zoning section in the algorithm is linked to the frame BIM model once. The quantity of the changed zoning plan for construction and the process plan establishment process can be checked in real time.

Building temporary materials and construction equipment BIM library
Perform construction BIM work using parametric-based BIM library
Based on the specifications presented in the catalog for temporary materials and construction equipment for field application, a virtual BIM model with the same size as the real thing is built, and the parameter-based library can be operated only with numerical control such as length, angle, and distance,
By performing a construction simulation that can check the installation of temporary materials in a narrow space, whether equipment can be moved, and the distance between materials and lifting, it is possible to solve the problems of reviewing construction risks at domestic and foreign construction sites in advance.

BIM model lightweight (4D system deployment and utilization)
4D System stabilization with BIM export extension testing
BIM models are being created with different tools for each type of construction using architectural/structural Revit, rebar/steel Tekla, and atypical sheath Catia or Rhino, and BIM utilization is very poor due to data capacity problems only with IFC extensions. A research was conducted to solve these problems and maximize the effectiveness of the operational aspect, and a 4D system for operating a multi-construction type collection model of up to 98.7% was established.

Data switching system Between BIM authoring tools
Building a fast and accurate BIM model that leverages the advantages of different BIM authoring tools
In creating a 3D model, the methodology and the advantages/disadvantages of using each tool clearly coexist, and even in BIM, there is a difference in results due to representative mesh and Nurbs modeling methods.
We use "Rhino, Inside, Lit" to select and use only each functional advantage to create quick and accurate results, and this study is to build an "purpose-oriented Open-BIM environment."
Application in practice
1
Structural BIM model automatic generation system
Automatically generate algorithm utilization structures (framework) BIM models to increase work productivity
Since the rapid establishemnt of the BIM model is a prerequisite for leading to the utilization stage, it is a study that creates BIM models within the shortest period of time through automatic recognition of drawings by members based on algorithms, using Grashopper optimized for algorithm creation and driving, automatically creates a stable structural BIM model, and uses "Rhino. Inside. Revit" to Re-Present BIM shapes and information in Revit. The BIM model created in this way is created with the same native model as the one worked on Revit, and normal BIM work can be performed.

Formwork BIM model automatic generation system
Structural BIM model-based formal BIM model and mass output automation solution
In the frame work, the construction of the formwork should be comprehensively reviewed together with temporary materials such as supporter and scaffolding, temporary lines for installation, and free space, so the construction risk (installation, dismantling, temporary instllation, volume review, etc.) is checked in advance before the start of the main work, and the BIM work for perfect construction is carried out by creating a formwork BIM model. This study aims to automatically extract surface, calculate quantity, and automatically generate formwork BIM shape models in various structural members such as square, diagonal, circular, and rotational.

Study for BIM-4D Auto Matching
Fast 4D simulation deployment with WBS and OBS code matching
It is difficult to understand complex process progress at a glance with the use of different process tables for each project and at least 60 pieces of a large amount of network process tables (P6) A3 paper, but the tool that can manage it efficiently is a good tool for reviewing process tables that are visualized during on-site process management with 4D simulations and can improve work efficiency.
The downside is that it takes a lot of time to modify and update 4D simulations when changes occur.
Some practical applications in progress

Construction zoning automation
Derivation of optimal construction zoning plan using AI technology
In the frame work, the construction zoning plan should minimize human errors and produce fast/accurate results as the plan should be established based on data and characteristics such as daily installation and ready-mixed concrete supply. In the construction field, AI technology is also being introduced as technology develops. Therefore, it is a basic study to establish an optimal zoning plan using ML (machine learning) technology based on overall closed conditions (Data Set) such as construction area, daily pouring volume, structure and on-site entry/exit.

Development of algorithms-based construction simulator
3D virtualization of construction sites for performing construction simulation
The construction site is a complex process, and construction, process, and safety simulation work using BIM should be preceded as various (temporary) temporary materials and large construction equipment are simultaneously constructed in a very complex manner. This is a basic study to examine various construction risks that can occur during actual construction through simulation using the BIM model such as gravity, load, collision, and speed using unreal engine and blueprint with graphic performance very similar to actual construction.

5D system establishment and utilization study
Building a system for cost management according to the construction process using BIM
In the construction field, it can be divided into 3D, 4D, and 5D. 3D refers to a BIM model with three-dimensional shapes and information, 4D is a 3D+process (Time) that goes further into the construction process, and 5D is a concept of 4D+cost and is divided into 'cost/schedule integrated management', and it is a system that can integrate design, process, and cost during the construction process to systemize and manage it. This study is a basic study on the relationship between WBS, OBS, and CBS for effective 5D system construction in the field process management (execution) stage, rapid response to changes in real time, and cost conversion according to the process rate corresponding to individual process WBS activity.

BIM-based good flow analysis simulator
Analysis of excellent flowchart using building and terrain models created by BIM
Large-scale, large-scale projects, and sites located on slopes are greatly affected by heavy rain during construction. In particular, when rainwater flows in during deep underground excavation work, civil engineering temporary structures may sink or collapse, leading to safety accidents.
This study aims to select excellent flow and final collection resin through drop density prediction using buildings and terrains generated by BIM, and it is expected to be used to review design and construction consistency for UG (Underground) construction.
