# NEXUS Construction Platform

> NEXUS is a beta, AI-assisted construction operations platform for project discovery, plans and estimating drafts, bidding records, project workflows, field evidence, approvals, and payment records.

NEXUS is intended for Owners, General Contractors, Subcontractors, and construction operations teams. AI output is advisory and requires qualified human review. NEXUS software records must not be interpreted as proof of licensed estimating, inspection, legal review, regulated escrow custody, a bank balance, or live payment settlement. Provider-backed capabilities require separately verified configuration, eligibility, compliance, and reconciliation.
