sizeless

sizeless is an AI documentation platform for civil engineering and pipe construction that turns a smartphone video of an open trench into a centimeter accurate 3D point cloud, CAD drawings and GIS ready data. A field technician films the trench with an iPhone Pro, and the platform reconstructs the scene, identifies infrastructure such as couplings and conduits, and produces the deliverables a utility needs before the trench is closed. It is built for utility companies, contractors and network operators that document house connections, heating networks and other underground infrastructure. From a single scan the platform generates DWG and DXF plans, GIS models and BIM data, and it works without GPS, so it is usable in basements and below ground. Documentation is turned around within 72 hours, which lets contractors bill sooner and close trenches faster, and no surveyor is needed on site. The reconstruction algorithms were developed at ETH Zurich, and the capture app, SiteScan, is available on the App Store. Data is stored in the EU under GDPR, and the company states that ISO 27001 certification is in progress. Pricing is not published. Contracts are arranged directly with the vendor. sizeless is a Zurich based company founded by engineers from ETH Zurich and UC Berkeley and backed by Y Combinator.
