2D vs 3D Measured Building Survey: Which Should You Order?
When commissioning a measured building survey, you have a choice between a 2D survey — traditional CAD drawings — and a 3D survey that includes a point cloud and a BIM model. Both produce accurate drawings, but they differ in what they deliver, how they are used, and how much they cost. icelabz provides both survey types.
What Is a 2D Measured Building Survey?
A 2D measured building survey produces drawings in two dimensions — floor plans, elevation drawings, and sections — in DWG (AutoCAD) format. The drawings are dimensioned, accurate representations of the building, but they are flat — each drawing is a separate view of the building from a specific angle.
A 2D survey is the traditional format for measured building surveys and is sufficient for most architectural design purposes. The architect uses the floor plan, elevation, and section drawings to develop their proposals, and the drawings are included in the planning application.
What Is a 3D Measured Building Survey?
A 3D measured building survey goes further, capturing the building in three dimensions. The survey typically includes:
- A point cloud — a dense 3D dataset of millions of measurement points covering all visible surfaces
- A BIM model in Revit format — a 3D model built from the point cloud data, with building elements modelled as intelligent objects
- 2D CAD drawings extracted from the BIM model
The point cloud is a permanent, verifiable record of the building as it existed at the time of the survey. The BIM model is a working 3D representation that can be used for design, coordination, and facilities management.
When to Choose a 2D Survey
A 2D survey is the right choice when:
- You only need floor plans, elevations, and sections for a planning application or a simple design project
- Your design software is 2D CAD-based and you do not need a 3D model
- Your budget is tight and the additional cost of a 3D survey is not justified by the project requirements
- The property is simple and straightforward, with no complex architectural features
A 2D survey is more cost-effective than a 3D survey for straightforward projects where only traditional drawings are needed.
When to Choose a 3D Survey
A 3D survey is the right choice when:
- You need a BIM model for design coordination, construction planning, or FM
- The property has complex architectural features — curved walls, complex roof structures, detailed ornamentation — that are better captured in 3D
- You need the data for multiple uses: design, FM, space planning, asset management
- You want a permanent digital record of the building that can be re-processed in the future without returning to site
- You are working on a project where the client or the design team specifically requires a BIM model
A 3D survey costs more than a 2D survey, but the additional data — the point cloud and the BIM model — provides value that a 2D survey cannot match.
Cost Comparison
A 2D measured building survey for a typical residential property — a three to five bedroom house — typically costs from around 600 to 1,000 pounds. A 3D survey for the same property — with point cloud and Revit BIM model — typically costs from around 1,000 to 1,800 pounds.
The additional cost of a 3D survey reflects the additional scanning time on site and the additional processing time to produce the point cloud and the BIM model. For larger commercial properties, the cost difference is proportionally smaller.
What the Point Cloud Provides
The point cloud is one of the most valuable outputs of a 3D survey. It is a permanent, verifiable record of the building as it existed at the time of the survey — every surface that the scanner could see is captured in the point cloud.
The point cloud can be used for:
- Verification of the BIM model against the original scan data
- Production of additional drawings or views without returning to site
- Structural analysis and deformation monitoring
- Generation of cross-sections and profiles at any position in the model
- Integration with other 3D data — site topographical data, infrastructure data
The point cloud is delivered in PTS, E57, or RCP format, which can be opened in a wide range of software applications.
What the BIM Model Provides
The BIM model is a 3D representation of the building in Revit format. Unlike a 2D drawing, where each element is a line or a shape, each element in a BIM model is an object with properties — dimensions, materials, specifications, and more.
The BIM model can be used for:
- Design development in 3D
- Clash detection with structural and M&E design
- Construction sequencing and logistics planning
- Extraction of 2D drawings at any scale
- Facilities management and space planning
- Generation of schedules — door schedules, window schedules, room data sheets
The BIM model is delivered in RVT format (native Revit) and IFC format (open BIM interchange format for use with other software).
Which Should You Choose?
The choice between a 2D and a 3D survey depends on your specific project requirements. Consider the following questions:
-
Do you need a BIM model? If the client, the design team, or the planning authority specifically requires a BIM model, choose a 3D survey.
-
Do you need the data for multiple uses? If the survey data will be used for design, FM, space planning, and asset management, a 3D survey provides more value than a 2D survey.
-
Is the property complex? If the property has complex architectural features that are difficult to capture accurately in 2D, a 3D survey may be more appropriate.
-
What is your budget? If the budget is tight and the project does not require a 3D model, a 2D survey is the more cost-effective choice.
icelabz provides both 2D and 3D measured building surveys. We can advise on the most appropriate survey type for your project and provide a fixed-fee quote for the option you choose.
Understanding LOD in 3D Surveys
The Level of Development (LOD) of a BIM model defines how detailed and data-rich the model is. For measured building surveys, common LOD levels are:
LOD 100: Conceptual model — approximate location, size, and shape only. Suitable for early-stage design or basic space planning.
LOD 200: Approximate geometry — general elements with approximate dimensions. Suitable for design development and simple coordination.
LOD 300: Precise geometry — elements modelled to sufficient detail for construction planning. This is the most common LOD for measured building surveys and is suitable for most architectural design and planning applications.
LOD 350: Construction-ready — elements modelled with sufficient detail for fabrication and assembly. This is required for projects where detailed construction documentation is needed.
The LOD you need depends on the project stage and the intended use of the model. For most residential and commercial design projects, LOD 200 or 300 is sufficient. LOD 350 is typically required for detailed construction, manufacturing, or FM handover purposes.
How a 3D Survey Process Works
The 3D measured building survey process starts with the site visit. A surveyor uses a terrestrial laser scanner to capture a dense point cloud of the property. The scanner is positioned at multiple locations throughout the building — typically three to ten positions depending on the size and complexity — and each scan position captures millions of measurement points covering all visible surfaces.
The point cloud is registered after the site visit to produce a single unified dataset covering the entire property. From this point cloud, a BIM modeller builds the 3D model in Revit, tracing the geometry of the building and creating modelled objects for walls, floors, roofs, windows, doors, and structural elements.
The deliverables — point cloud and BIM model — are delivered in standard formats. The point cloud is in PTS, E57, or RCP format, which can be opened in a wide range of software. The BIM model is in RVT format (native Revit) and IFC format (open BIM interchange for use with other software).
The Value of a Point Cloud for Future Work
One of the most compelling reasons to commission a 3D survey is the permanent record that the point cloud provides. Unlike a 2D drawing, which is a static representation of the building at the time of the survey, the point cloud is a comprehensive dataset that can be re-processed indefinitely.
If the building needs to be surveyed again in the future — for a renovation, an extension, a change of use, or a facilities management update — the original point cloud can be re-processed without returning to site. This saves the full cost of a new survey and provides a consistent dataset across the building's lifecycle.
For property investors and portfolio managers, having a point cloud record of each property in the portfolio provides a permanent reference that supports due diligence, asset management, and disposal activities across the entire investment horizon.
Choosing the Right Survey Format
The decision between 2D and 3D ultimately comes down to how the survey data will be used. If you only need traditional drawings for a planning application and the design is 2D-based, a 2D survey is the more cost-effective choice. If you need a BIM model for design coordination, construction planning, or FM, or if the property has complex features that benefit from 3D capture, a 3D survey is the better investment.
