3D Modeling

We offer 3D modeling solutions for every stage of a project with different Levels of Detail (LOD) ranging from LOD 200 to LOD 500 for various types of projects, including buildings, highways, bridges, MEP (Mechanical, Electrical, and Plumbing), and landscape master plans. Determining the level of detail and accuracy of the final output is crucial before initiating the 3D modeling workflow.

3D Modeling Data Sources

1. Detailed Engineering Design (DED)
Detailed Engineering Design (DED) is the most comprehensive stage of project design, providing precise technical drawings, specifications, and calculations required for construction. It ensures the feasibility, constructability, and compliance of the project with engineering standards and regulations. DED includes structural, architectural, and MEP (Mechanical, Electrical, and Plumbing) details, as well as material specifications and construction methods, serving as a crucial reference for contractors and stakeholders.

2. Final Engineering Plan (RTA)
The Final Engineering Plan (RTA) is a refined and approved version of the design, ready for implementation. It incorporates adjustments based on reviews, regulatory approvals, and site conditions, ensuring all elements align with the project's execution plan. This document serves as the final guideline for construction, outlining design accuracy, construction methods, and compliance requirements.

3. Shop Drawings
Shop Drawings are highly detailed technical illustrations created by contractors, manufacturers, or fabricators to ensure accuracy in the construction process. These drawings contain precise dimensions, material specifications, fabrication details,

and assembly instructions, helping to align the construction with the approved design. Shop drawings also facilitate coordination between different building systems, minimizing errors and ensuring smooth installation.

4. As-Built Drawings
As-Built Drawings are the final set of drawings prepared after construction is completed, documenting any changes or modifications made during the building process. These drawings reflect the exact dimensions, materials, and structural adjustments, providing a valuable reference for facility management, maintenance, and future renovations. As-built drawings ensure that the completed structure aligns with actual site conditions.

5. Point Cloud Data
Point Cloud Data is a collection of highly accurate spatial points obtained through LiDAR (Light Detection and Ranging) or 3D laser scanning, creating a digital representation of physical structures. This data is essential for Scan-to-BIM, renovation projects, structural analysis, and topographic surveys, allowing for precise 3D modeling and detailed documentation of existing conditions.

Workflow 3D Modelling

1. Data Sources
Before creating a 3D model, it is necessary to consider the source data first. Each data source requires different preprocessing in order to be modeled.

2. Data Terrain Setting, Create Mesh
Organize terrain data according to project needs, and build meshes.

3. Modeling 3D
3D modeling can be done using a variety of software, such as autodesk, sketchup, etc.

4. Parameter Project and Attribute Input
Add object attributes, such as building ID, height, date, and other metadata according to the project.

5. Texturing, Shading, and Lighting
Provides color, detail, and material to a 3D model. Can use UV projection techniques, texture painting, or procedural textures. Then adjust the shading and lighting to give a realistic look.

6. Rendering
Process 3D models into realistic images or videos.
