For AI and data teams

Ground truth for AI in architecture, engineering and construction.

Foundation models learn building from text and drawings. We hold the work itself: rooms modeled from their scans, every finish and pipe on record, each decision and who made it, and what the job really took.

Model · one bath A bathroom modeled from its scan, with its plumbing and power drawn through the finishes: Blue Celeste marble shower walls, the existing soil stack, the fan heater and light, the toilet drain and vent, hot and cold supplies to a 61 inch double vanity, and a 60 square foot heated floor.

Training data that matches the real building.

Tens of thousands of real jobs across thousands of homes, each home with one record from the first visit on. The records come from the systems the work ran on, not scraped from the web, so a model can learn how a space, a plan and a result line up.

Photo · bath, rough-in The bath taken back to the studs: new shower wall framing with red and blue supply lines, open joists, the window wall, and the subfloor laid in plywood.
Plan · from the scan Third-floor plan measured from the phone scan, with every wall dimension; the bath is highlighted, with its window on the outside wall.
The gutted bath and the floor plan measured from the same scan. The window, the walls and the room size all line up.
  1. The house

    Phone scans and floor plans, before and after. Rooms, fixtures and finishes with their sizes.

  2. The decisions

    Each choice with who made it, when and why: a heated floor added, a whole-home water filter added as a change order, a vanity size recorded.

  3. The outcome

    The price paid, the changes along the way, the schedule as it actually ran, and photos when the work was done.

The same room, as each trade reads it.

One bathroom from a remodel. Paired sheets, takeoffs and dated updates show what a drawing means to the tile setter, the plumber and the electrician, and how it changed on site.

Drawn from one technician's real schedule, with the map, places and names removed.

And the work as it actually ran.

Visits, time windows and routes: how long the work takes in the field, not on paper. Here, one plumbing and heating technician's day: a main valve, a gas smell at a boiler, a failed water heater and a no-heat call, each its own work order.
