Fernwärme Ulm: one site visit instead of many.
FUG is converting its district heating network from steam to hot water, building by building. Every conversion used to start with a site visit by five people: a customer advisor, a surveyor, two technical planners and an electrician. Critical details still sometimes meant a second trip. Now the customer advisor captures the building with a smartphone on the first visit. The data goes straight into the sizeless workspace, where the planners plan pipes and transfer stations while the advisor writes the cost estimate in parallel.
- One visit per building
- One person instead of five
- Planning and offer in parallel


Hamburger Energiewerke: as-built records in days, not months.
Getting into tenants' cellars takes a lot of coordination. With sizeless, Hamburger Energiewerke only needs access once. Drawing is automated, and the results go straight into their GIS. For the first time, they have independent quantities to check against.
- One visit per cellar
- No manual drawing
- GIS-ready data
One site visit. No coordination with a surveyor.
- One site visit, no coordination with a surveyor.
- 72 hours from scan to ready-to-use results, centimeter-accurate against a professional survey.
- Fewer people per measurement: your own crews, with the smartphone they already carry.
- Complete 3D evidence before backfilling, including crossing lines and house entries.
