MeltPlan — Construction-Aware AI for Design, Precon, and Collaboration is a preconstruction productivity platform that uses construction‑aware AI trained on codebooks, specs, drawings and real project data to power an AI code consultant (instant, cited code answers), estimator‑reviewed AI takeoffs from 2D/3D plans, and coordinated project models that read geometry and flag clashes; teams use it to speed code research and estimating, reduce manual rework and risks, and keep a single source of truth across owners, architects, GCs, trades, and inspectors.
