3D Laser Scanning (BIM)

3D Laser Scanning BIM Surveys London, Southampton. 


Building information modelling (BIM) and 3D Scanning Services across London


Cadmap provide all aspects of 3D laser scanning.

The Leica P20 Scanner can scan up to 1 million points per second Leica Scan Station P20 is the ideal instrument when very short time windows are available for capturing High-Definition Survey data or when ultra-high density is required. 



From building elevations to internal floor plans and more specialist projects we have the experience and expertise to accommodate your project.

Cadmap use the latest Leica Cyclone software to register, edit and manipulate the raw point cloud data, from cutting out trees to creating sections throughout an entire building, after the Registration process the Point Cloud Data is imported into "Leica Cloudworx for AutoCAD 2016" where the drawing process begins. 

The data we capture can be rendered to a high standard using the latest CGI   software such as REVIT and 3DS MAX.


What is a BIM Revit Model?


A BIM (Building Information Modeling) Revit model refers to a digital representation of a building or infrastructure project created using Autodesk Revit software. Revit is a powerful and widely used BIM tool that allows architects, engineers, and construction professionals to collaboratively design, visualize, simulate, and document building projects.

In a BIM Revit model, the building's geometry, structural elements, architectural components, mechanical and electrical systems, and other relevant information are integrated into a single digital model. This model serves as a central repository of information that can be accessed and shared by project stakeholders throughout the lifecycle of the project, from design and construction to operation and maintenance.

The BIM Revit model contains a rich set of data associated with each element or component, including its properties, dimensions, materials, performance characteristics, and relationships with other elements. This data enables more accurate and detailed design visualization, analysis, and coordination.

Some key features and benefits of a BIM Revit model include:

  1. Integrated Design: The model allows for the simultaneous design and coordination of multiple disciplines, such as architecture, structure, and MEP (Mechanical, Electrical, and Plumbing), fostering collaboration and reducing conflicts or clashes in the design process.

  2. 3D Visualization: The model provides a 3D representation of the building, enabling stakeholders to visualize and explore the design from various angles, perspectives, and levels of detail.

  3. Clash Detection: The model facilitates clash detection, where potential conflicts between different building systems or components can be identified and resolved before construction, reducing errors, rework, and delays.

  4. Quantities and Cost Estimation: The model can generate accurate quantities and material takeoffs, supporting cost estimation, procurement, and project planning.

  5. Construction Sequencing: The model can be used to simulate construction sequences and visualize the construction process, helping with project scheduling, logistics, and site coordination.

  6. Facility Management: The BIM Revit model can serve as a foundation for facility management, allowing building owners and operators to access information about the building's components, maintenance schedules, and systems for efficient operation and maintenance.

Overall, a BIM Revit model enhances collaboration, improves design coordination, reduces errors, and provides a comprehensive digital representation of a building project, enabling stakeholders to make more informed decisions throughout the project lifecycle.

Levels of Development in BIM.

The different levels of development (LOD) in REVIT and BIM. LOD 100 - LOD 200 - LOD 300 - LOD 400 specifications.




LOD 100 BIM GUIDE

  1. LOD 100: This represents the most basic level of development. At LOD 100, the model elements are represented in a very conceptual form. They might resemble generic placeholders to represent the approximate location, size, and shape of the building components. These placeholders provide a rough idea of the overall building footprint and layout.


LOD 100 BIM EXAMPLE



  1. LOD 200 BIM GUIDE

  2. LOD 200: At this level, the model elements become more defined. They start to resemble actual building components with approximate quantities, shapes, sizes, and locations. However, they lack specific detail and are still generic in nature. LOD 200 models are typically used for early design and conceptualization stages where more detailed information is not yet available.


LOD 200 BIM EXAMPLE


LOD 300 BIM GUIDE

  1. LOD 300: This level represents a significant advancement in detail. At LOD 300, the model elements are developed to include accurate geometry, quantity, size, shape, location, and orientation. They may also include detailed information about how different elements interact with each other. LOD 300 models are commonly used for detailed design and coordination purposes, where precise information is required for accurate visualization and analysis.


LOD 300 BIM EXAMPLE




LOD 400 BIM GUIDE

  1. LOD 400: LOD 400 represents an even higher level of development. At this stage, the model elements are not only geometrically accurate but also include specific information about fabrication, assembly, and construction details. LOD 400 models may include information about connections, tolerances, materials, and finishes, enabling contractors and fabricators to use the model for procurement, fabrication, and construction planning.
