For architects and design professionals working on refurbishment, planning applications, and detailed design, accurate existing condition data is paramount. Photogrammetry has emerged as a powerful, efficient technique to capture this reality. But what exactly is it, and how can it benefit your project?

In essence, photogrammetry is the science of making measurements from photographs. It allows us to generate precise 3D meshes of buildings, structures, and sites by processing hundreds, if not thousands of overlapping 2D images. By applying the principle of triangulation to photographs taken from different positions, specialised software can extract accurate 3D coordinates, building a digital twin of the subject. 

Method: Aerial vs. Terrestrial Photogrammetry

The method used depends on the project’s scope and requirements.

Aerial Photogrammetry (via Drone)

Drones provide a unique perspective, capturing data from above. This method is invaluable for:

• Supplementing terrestrial surveys on large topographical sites.
• Surveying inaccessible areas like complex rooftops, facades, or unsafe structures.
• Creating vast 3D terrain models.

At 3Deling, we integrate aerial photogrammetry with ground-based laser scanning. This hybrid approach ensures comprehensive coverage and enhances the overall accuracy of the final 3D model or 2D drawings, delivering a complete dataset for your site.

Terrestrial Photogrammetry (Ground-Based)

Using handheld or tripod-mounted cameras, this method captures intricate details at ground level. It is ideal for:

• Generating photorealistic 3D meshes of building interiors, architectural details, or specific objects.
• Creating high-resolution orthophotos for elevations and interior walls.
• Documenting complex architectural features for refurbishment and detail design.

From Images to Accurate 3D Data: The Processing Workflow

Capturing the photos is just the first step. The raw imagery is processed in specialised software which analyses common points across overlapping images to calculate camera positions and construct a dense 3D point cloud and mesh. Each photograph is represented by a white dot on the image.

For projects requiring absolute precision and real-world coordinates that are essential for measured building surveys and planning applications, we use a total station to survey control points across the site. These points are imported into the software to georeference the model and perform bundle adjustment, locking the 3D data into the Ordnance Survey coordinate system. Without this control, the model would lack scale and true geographic position.

Key Outputs: 3D Mesh and Orthophoto’s

The 3D Mesh

This can be exported in standard formats (.obj, .glb, .stl) and imported directly into your software:

• CAD & Revit: Use the mesh as an underlay to trace and draft accurate 2D drawings or create 3D models
• Analysis & Visualisation: The photorealistic mesh can be used for client presentations, sunlight studies and noting defects.
• The same 3D mesh can also be uploaded to WebPano, where it can be viewed and explored online, making it easy to review geometry, understand spatial relationships, and share the model with project teams or clients.

Orthophotos: The Measurable Photograph

An orthophoto is a geometrically corrected image where lens distortion and perspective have been removed. Think of it as a photograph with the uniform scale of a map.

• For Architects & Planners: They provide true-to-scale but photorealistic elevations, perfect for annotating dimensions, planning applications and facade studies.
• For Surveyors: They enable accurate measurements of distances, areas, and features directly from the image, often used in conjunction with traditional drawings.

Enhancing Your Survey & Design Process

At 3Deling, we leverage photogrammetry not as a standalone solution, but as a powerful component of our integrated survey toolkit. When combined with laser scanning, it provides an unmatched balance of photorealistic detail, geometric accuracy, and operational efficiency.

Whether you need a detailed record of a listed building for sensitive refurbishment, accurate site data for a planning submission, or a fast-track model for a design proposal, photogrammetry offers a compelling solution.

3D laser scanning is increasingly becoming a standard in construction, industrial facilities, and infrastructure projects. Many companies ask about 3D scanning costs, but there is no simple “price list on the website.” Why? The cost depends on multiple factors, and each project is unique.

In this article, we break down the 3D scanning pricing process, factors affecting costs, and how to invest smartly in accurate measurement data.

Why There Is No Standard 3D Scanning Price

The price of 3D scanning is influenced by several factors:

Object Type

Residential, office, and industrial facilities have different requirements. Industrial sites often require access passes, safety training, and work coordination during specific hours, increasing daily scanning costs. Offices or residential buildings are usually cheaper, but costs can rise if access is limited, e.g., in occupied historic buildings.

Location

Scanning the same object in Poland versus abroad may vary due to logistics. International projects often involve visas, work permits, and transport arrangements. Minimum costs for overseas projects typically start at around €2,000 net.

Scanning Scope and Density

Larger objects or more detailed scans require more measurement points, which increases labor time and costs. A single operator can complete ~100 scans per day, so estimating the number of scans helps predict fieldwork duration.

Color vs. Monochrome Scans

Color scanning provides an extra layer of data, useful for WebPano visualization and further design work, but it is more time-consuming and expensive. Grayscale scanning is more affordable and often sufficient when only geometric data is needed.

Additional Products

The basic deliverable is a point cloud, but clients may also require a mesh model, 3D CAD/BIM model, 2D drawings, or data processing support. Defining the project scope early ensures the correct number of scans and reduces unnecessary costs.

Timeline and Logistics

Urgent projects needing multiple operators and scanners cost more, while long-term, multi-stage projects can benefit from more favorable daily rates.

3D Scanning Services for Industry and Beyond

“Many clients hesitate to inquire because they associate 3D scanning only with large industrial projects. We also handle smaller assignments—the key is matching the scope to the actual needs.”
— Paweł Dudek, CEO of 3Deling

What Clients Should Provide for Accurate Quotes

• Object Location – Google Maps link or detailed description

• Scanning Scope – mark the area on a drawing or screenshot

• Photos and Interior Details – floors, attic, basement, access limitations

• Object Accessibility – empty, occupied, or difficult to scan

• Purpose of Survey – software where the data will be used (Revit, CAD, WebPano)

• 3D Model & 2D Drawing Details – complete a LoD file to specify level of detail, formats, and print copies

With this information, quotes are usually ready within one business day, or the same day for urgent projects.

3D Scanning Pricing Process

1. Client submits project information.

2. Team analyzes object type, location, accessibility, and scope.

3. Estimate the number of scans needed.

4. Determine fieldwork time, logistics, and required personnel/scanners.

5. Calculate daily scanning cost and additional deliverables.

6. Send the quote—usually within one day.

How to Optimize Costs

• Define Project Goals – inventory data vs. design data requires different detail.

• Provide Comprehensive Information – photos and marked scanning areas reduce risk and cost.

• Request Multiple Quote Options – e.g., point cloud only vs. point cloud + 3D model.

• Use WebPano – often reduces the need for full 3D modeling.

Conclusion

There is no single 3D scanning price list—and that’s a good thing. Each project is unique. Costs depend on size, complexity, deliverables, and required accuracy. A well-prepared inquiry ensures a reliable quote and optimized expenses.
