# sizeless > sizeless provides AI-powered as-built documentation for civil engineering and pipeline construction (Tief- und Rohrbau). Site crews scan open trenches and house connections with a smartphone (iPhone Pro); sizeless turns the capture into centimeter-accurate 3D point clouds, norm-compliant DWG/DXF as-built plans, and BIM/GIS-ready exports — documentation delivered within 72 hours, trenches backfilled immediately after the scan. Key facts: - One smartphone capture produces every deliverable: 3D point cloud, 2D CAD (DWG/DXF) with automatically detected pipes, couplings and utilities, and structured BIM/GIS outputs. - No separate surveying appointment: technicians document house connections independently, trenches are backfilled right after the video. - Continuous 3D evidence including third-party utilities and house entries; works without GPS in basements. - Audit-proof, norm-compliant documentation for utilities and network operators. - Company based in Zürich, Switzerland. Capture app "SiteScan" is available on the Apple App Store. ## Pages (English) - [Home](https://sizeless.co/en): product overview — AI workflow, outputs, process - [FAQ](https://sizeless.co/en/faq): common questions about accuracy, workflow, and deliverables ## Seiten (Deutsch) - [Startseite](https://sizeless.co/): Produktüberblick — KI-Workflow, Ergebnisse, Prozess - [FAQ](https://sizeless.co/faq): häufige Fragen zu Genauigkeit, Ablauf und Lieferergebnissen ## Contact - [Demo request](https://sizeless.co/en#demo-request) - Email: info@sizeless.co - [LinkedIn](https://www.linkedin.com/company/sizeless-ai/) - [SiteScan on the App Store](https://apps.apple.com/app/sitescan/id6748157116) ## Sitemap - [XML sitemap](https://sizeless.co/sitemap.xml): all indexable URLs (German at bare paths, English under /en)
