Minimal site survey, the agent derives the rest

Four measurements instead of twenty-five: the agent derives the rest.

Here are the roof measurements and the scope: we're redoing the two street-side slopes and the dormer. Give me the quantities.

12 quantities reconstructed
Areas, verges, eaves and scaffolding reconstructed. Two quantities are missing: valley length and dormer cheek height, to measure on site.

Twenty-five annotations on the 3D model for a simple roof.

Annotating a whole roof on the 3D model takes twenty-five measurements; by hand, the roofer takes four and works out the rest in his head.

with the agent

A few measurements and a sentence; each quantity states whether it's derived.

From a few measurements (ridge, one verge, eave height, dormer dimensions) and a sentence about the scope, it reconstructs areas, verges, eaves and scaffolding, and states for each quantity whether it's measured, derived, or missing.

  1. 01Take a few measurements. Ridge, one verge, eave height, dormer dimensions.
  2. 02Describe the scope. One sentence, slope by slope: what's being redone, what stays.
  3. 03Apply your rules. A slope has two equal verges, the ridge equals the eave…
  4. 04Mark each quantity. Measured, derived, or missing, with the assumption used.

the gain

Half as many measurements to take. Tested on a real job: quantities accurate to within 5%, except for valleys and dormer cheeks, which still need measuring.

To get started: Write your derivation rules once (a slope has two equal verges, the ridge equals the eave…) and describe the scope slope by slope.

we check together whether the data exists, try it on a real case from your week, you correct it, and the rule gets written down. if it doesn't work, we'll tell you.
