STRUCTURAL AS-BUILT BIM MODEL (LOD 100–350)
As-Built modeling from technical documentation and point clouds (Scan to BIM)
WHAT IS A STRUCTURAL AS-BUILT BIM MODEL?
A Structural As-Built BIM Model is the digital representation of a structure according to what was actually built on site.
Unlike the design model, the As-Built model incorporates the final conditions of the project, reflecting the modifications made during construction to ensure that the digital information corresponds to the physical reality of the building.
More than just a record of the work, it constitutes a digital asset that facilitates the technical management of the project throughout its life cycle.
When the project has a point cloud from a 3D laser scan, the BIM model can be developed directly on this information, achieving a highly accurate representation of the existing condition of the structure.
WHY DEVELOP AN AS-BUILT BIM MODEL?
An As-Built model provides reliable information for the management and evolution of a building.
Its main benefits include:
- Digital record of the final condition of the structure.
- Updated information for asset management.
- Greater reliability for future interventions.
- Reduction of uncertainty in renovations.
- Support for maintenance processes.
- Better planning of expansions and adaptations.
- Technical basis for project life cycle management.
- Centralization of the constructed structural information.
- Greater accuracy when developed from point clouds.
Reduction of the risk of omitting existing elements.
OUR SERVICE
STRUCTURAL AS-BUILT BIM MODEL
At KAMON & CO. we develop structural As-Built BIM models from technical documentation, existing BIM models or point clouds from 3D laser scanning supplied by the client.
Each model is updated according to the actual condition of the structure, incorporating modifications made during construction or captured using three-dimensional surveying technologies.
Our goal is to deliver a reliable, accurate model ready to support operation, maintenance, future upgrades, and comprehensive asset management.
SCOPE OF SERVICE
• Review of construction information.
• Analysis of modifications made.
• Update of the existing BIM model.
• Modeling of constructed elements.
• Incorporation of changes made during construction.
• Adjustment of geometries and placement of elements.
• Parameterization of updated information.
• Model organization.
• Validation of the As-Built model.
• Preparation of the model for asset management.
• Importing and managing point clouds.
• Linking RCP/RCS files.
• Structural modeling on point cloud.
• Geometric verification with respect to the point cloud.
• Validation of the correspondence between the model and the constructed reality.
The final scope will depend on the information provided and the specific needs of the project.
WORK METHODOLOGY
Our As-Built update process is developed using a methodology aimed at ensuring that the BIM model faithfully represents the constructed structure.
- Receipt of project documentation or point cloud.
- Technical review of the information provided.
- BIM environment configuration.
- Linking the point cloud (when applicable).
- Updating or developing the As-Built model.
- Parameterization of the elements.
- Quality control.
- Technical validation.
- Delivery of the As-Built BIM model.
TECHNICAL CONDITIONS
The accuracy of the As-Built model will depend on the quality and reliability of the information provided by the client.
When sufficient documentation is not available, additional technical visits, surveys, or validations may be required to ensure the correct updating of the model.
This service exclusively covers the updating of the BIM model according to the built condition and does not include structural design, preparation of structural plans, quantity take-offs or the development of new BIM models, except for separate contracting.
When the model is developed from a point cloud, this must be provided by the client in compatible formats (RCP, RCS, E57, LAS, or other previously agreed-upon formats). KAMON & CO. does not offer 3D laser scanning capture services unless established through a strategic alliance with a specialized provider.
LEVELS OF DETAIL (LOD)
- LOD 100 – Conceptual
Basic representation for general reference. - LOD 200 – General
Model with approximate information of the structural elements. - LOD 300 – Detailed
Accurate model according to the dimensions and location built. - LOD 350 – Coordination
Model with a higher level of detail to represent interfaces and encounters between elements.
The Development Level is defined according to the project requirements.
SOFTWARE USED
- Autodesk Revit for the development, updating and management of the As-Built BIM model.
- Autodesk Navisworks for coordination, review and validation processes of the model (when applicable).
Point cloud compatibility
When the client provides information from 3D laser scanning, we work with compatible formats for integration into Autodesk Revit, such as:
- Autodesk ReCap (RCP / RCS).
- E57.
- THE.
- LAZ.
- PTS.
- XYZ.
Note: The service includes the processing and integration of the point cloud provided by the client for the development of the As-Built BIM model. It does not include data capture using a 3D laser scanner.
WHO IS IT AIMED AT?
• ARCHITECTS
• CONSTRUCTION COMPANIES
• Public entities.
• Engineering companies.
• Structural Engineers.
• Asset managers.
• Maintenance companies.
• Building owners.
• Real estate developers.
Because knowing exactly how a structure was built is fundamental to managing its future.
DELIVERABLES
Depending on the scope of service contracted, the service may include:
- As-Built BIM model in RVT format.
- IFC model.
- NWC file for BIM coordination (when applicable).
- Model updated according to the work carried out.
- Model developed on point cloud (when applicable).
- Organized and parameterized model.

End-to-End BIM Solutions
The constructed reality, transformed into intelligent information.
Construction ends when the work is finished, but the management of a structure continues for decades.
An As-Built BIM Model provides a reliable digital representation of the built reality and, when developed from a point cloud, achieves a higher level of geometric accuracy for asset management.
At KAMON & CO. we transform technical documentation and 3D scanning data into intelligent BIM models that support the operation, maintenance and future interventions of the structure.
What is an As-Built BIM Model?
It is a BIM model that represents the actual condition of the structure once construction is complete, incorporating the changes made on site.
What is the difference between a design model and an as-built model?
The design model represents the projected structure, while the As-Built model reflects how it was actually built.
What information is needed to develop an As-Built model?
Final construction plans, existing BIM models, point clouds from a 3D laser scan, change logs, technical documentation and any information that allows validating the constructed condition.
Is it necessary to have a prior BIM model?
Not necessarily. We can update an existing model or develop an as-built model based on available documentation and information provided by the client.
Can you develop an As-Built BIM Model from a point cloud?
Yes. When the client provides a point cloud from a 3D laser scan, we can develop the structural As-Built BIM model using that information as the main reference.
Does KAMON & CO. perform 3D laser scanning?
No. Currently, the service includes the development of the As-Built BIM model from the point cloud provided by the client. Laser scanning can be managed through a specialized provider when the project requires it.
What is the purpose of an As-Built model?
It facilitates the operation, maintenance, remodeling, expansion and technical management of the asset throughout its life cycle.
How is the service priced?
The economic proposal is defined according to the size of the project, the complexity of the structure, the information available, the required Level of Development (LOD), and the requested scope.
