Fluidfield

Fluidfield: from the drawing to the wall, with proof. Before drywall closes, someone has to prove every electrical box and plumbing stub-out is where the drawings say. Today that proof is split across drawings, RFIs and site photos, and takeoff tools silently guess whatever the drawings leave open. Fluidfield keeps one auditable thread. Muse Spark reads the drawing set like a modeller: it surveys each sheet, decides where to look, and builds the model while geometry checks verify every region it picks. Where the drawings don't settle something, it asks instead of guessing: 15 questions on our test set, covering all 7 errors we planted, each with its evidence on the sheet. The reviewer's answers become a contract: an approved model recording who approved it, which decision drove each item, and a digest, exported as IFC. The pre-drywall walk then checks that contract on the wall. Each item is seen present, seen absent with proof, or not seen, which never passes, and a person signs. The walk is simulated today, with known camera positions. We measured what a real walk would take on real construction-site data, and that's our next step.
