How Nectain Helps Construction Teams
All Construction Documents in One Secure Place
Keep every plan, revision, permit, contract, RFI, and spec in one organized workspace. No more hunting through emails, drives, or smartphone — everyone works from the latest version.
AI-Powered Document Recognition & Extraction
Nectain automatically recognizes, classifies, and extracts data from drawings and construction documents. Save time on manual sorting and ensure accurate info reaches the right workflow instantly.
Faster Reviews, Approvals & Change Orders
Automated workflows route documents to the right people instantly. Track who needs to approve, what’s pending, and what’s next — so decisions move as fast as the project demands.
AI That Reads, Summarizes & Creates Critical Documents
