sizeless

sizeless is best understood as a narrow, deep tool rather than a platform. The four-step chain in the vendor's own copy — Grabenerfassung with an iPhone Pro at the pit, ETH-developed algorithms building a centimeter-accurate 3D point cloud, norm-compliant 2D as-built plans in DWG/DXF, then 3D models and GIS digital twins including Hauseinführungen — is a complete loop from field to office with no media breaks. That loop is the product. The pitch that "ein einziger Smartphone-Scan liefert jedes Ergebnis, mit dem Ihr Team bereits arbeitet" is the honest framing: it produces point cloud, 2D CAD and BIM/GIS outputs that plug into tools you already run, rather than asking you to adopt a new system of record. The strongest parts are the ones the vendor can actually demonstrate. Capture is done by your existing project team with no special hardware and no training, which is the real cost argument — you are not buying a scanner or hiring a surveyor, you are changing who holds the phone. GPS-free operation in Kellerbereichen and covered areas matters more than it sounds, because that is exactly where trench documentation gets messy and where conventional GNSS capture degrades. Revision safety is addressed structurally: foreign utilities (Fremdsparten) and house entries are recorded in the same scan, manual sketches disappear, and the vendor explicitly frames the output as something that can catch construction errors before backfill. The 72-hour delivery window is the number that determines whether the workflow fits your schedule, and the vendor puts it front and centre. The weaknesses follow from the same design. Because processing is cloud-based, nothing is available on site while the pit is open — you capture now and document later, which means the crew is shooting for the office, not for themselves. iPhone Pro is the only supported capture device, so Android crews and older iPhones are out. The company's language and go-to-market focus is German-speaking Europe; the site is bilingual EN/DE, but the substance is DACH infrastructure practice, and norm conformance is defined against that context. And centimeter accuracy is a documentation-grade claim, not a certified surveying claim — boundary measurement and legal cadastral work are not what this does. Where it fits: utility network operators, district heating teams and civil contractors in DACH who want a higher project throughput out of existing crews, and GIS/CAD departments tired of chasing field photos and hand sketches. Where it does not: global rollouts needing multi-language support and Android parity, projects that need instant on-site numbers, and any workflow where a licensed surveyor's signature is the deliverable. Treat it as a pilot that replaces one costly process step, not as a replacement for your surveying capacity.
