sizeless
Turn smartphone videos into centimeter-accurate 3D digital twins for trench documentation.
sizeless is a focused, practical solution for trench documentation that eliminates a bottleneck. The ETH-backed accuracy and iPhone-native workflow are genuine time-savers, but demo-only pricing and DACH-region availability limit reach for now. If you're a utility or civil firm in German-speaking Europe, it's worth a demo. Otherwise, consider alternatives like Pix4D or DroneDeploy for broader surveying needs.

Skip sizeless if you don't work in civil infrastructure or trench documentation, if you need on-site instant results, if your team doesn't use iPhones, or if you're outside German-speaking Europe.
Pricing is not public; you must book a demo to get a quote, so expect a sales process before you know costs.
sizeless uses a demo-based pricing model, typical for enterprise B2B software. It's best for mid-to-large utility and construction firms that value workflow speed and revision safety. Compared to traditional surveying (which costs time and money per visit), sizeless can reduce costs significantly, but initial pricing may be higher than simple CAD tools. Peers like Pix4D or DroneDeploy offer subscription models, but may require more hardware and expertise.

About sizeless
sizeless is a Swiss deep-tech startup spun out of ETH Zurich that turns smartphone videos into centimeter-accurate 3D digital twins for infrastructure construction and real estate. It targets utility network operators, civil engineering firms, and construction teams needing fast, revision-safe documentation of open trenches, house connections, and technical rooms. Using an iPhone Pro with the SiteScan app, workers capture a short video of an excavation. Proprietary ETH algorithms generate a high-resolution 3D point cloud, then auto-convert it into norm-compliant 2D CAD plans (DWG/DXF) and 3D GIS-ready models. The workflow eliminates separate surveying appointments and manual sketches—trenches can be backfilled immediately after capture. The platform achieves centimeter-level accuracy without GPS, working in basements where GPS fails. No specialized hardware or training is needed; existing crews use their own iPhones. Outputs integrate directly with standard GIS and CAD tools, providing objective documentation that speeds billing and improves revision safety. Currently available in German-speaking Europe via a demo-based sales model.
Behind the Verdict
sizeless attacks a very specific pain: the slow, manual process of documenting open trenches for construction and utility projects. The value proposition is clear—capture a video with an iPhone Pro, get a centimeter-accurate 3D point cloud and CAD plans within hours, and backfill the trench immediately. This speed is a major win for project timelines and billing. The ETH-born algorithm promises accuracy without GPS, which is crucial for basements and other GPS-denied areas. The focus on revision safety, including foreign utilities and house entries, addresses a real liability concern. However, the tool is not real-time; processing happens in the cloud, so results are not immediate on-site. It also requires an iPhone Pro (LiDAR), which could be a barrier for teams on other platforms. Pricing is only available via demo, making it hard to compare costs. Regional availability in German-speaking Europe limits its reach. For firms already using GIS/CAD, the output is ready to use, but direct API integration isn't mentioned, so fully automated pipelines may be hindered. It's a strong niche tool, but not for everyone.

Real-world workflow fit
Concrete scenarios for the personas sizeless actually fits — and what changes day-one when you adopt it.
Monteur on site captures an open trench with an iPhone Pro using SiteScan app, following guided steps.
Outcome: Video is uploaded; within hours, a 3D point cloud and CAD plan are delivered. Trench can be backfilled immediately, and documentation is ready for billing and revision safety.
PM needs to document a house connection and foreign utilities.
Outcome: One video captures everything; sizeless generates a comprehensive 3D digital twin with all elements, eliminating manual sketches and reducing disputes.
Specialist receives a new trench scan from the field.
Outcome: 3D model integrates directly into GIS, ensuring accurate asset records for future planning and maintenance without additional data entry.
Use Cases
- Capture an open trench video with an iPhone and get a 3D point cloud and CAD plan within hours
- Automatically document house connections and foreign utilities in a single scan for revision safety
- Eliminate separate surveying appointments and backfill trenches immediately after video capture
- Provide norm-compliant DWG/DXF plans for billing and acceptance without manual drafting
- Enable field crews to self-document technical rooms and excavations using a guided smartphone workflow
- Integrate 3D digital twins of underground infrastructure directly into GIS systems for future planning
Limitations
- Processing is not real-time; the video must be uploaded and processed in the cloud, meaning results are available later rather than on-site.
- The system currently requires an iPhone Pro (LiDAR capable) and a stable internet connection.
- Integration with existing GIS/CAD tools is supported, but direct API connectivity is not mentioned, which could be a barrier for fully automated pipelines.
- Pricing is only available via demo inquiry, making it hard to evaluate costs upfront.
