Problem
Construction contractors and estimators often spend extensive time manually extracting material quantities from blueprint PDFs or TIFFs, a process that is labor‑intensive, error‑prone, and slows bid preparation. Traditional estimating software requires users to learn complex tools and still relies on manual verification, limiting speed and accuracy.
Solution
2by4.ai offers a done‑for‑you service that combines AI‑driven extraction of material quantities with expert estimator verification. Users upload their construction plans through a secure portal; AI agents parse every drawing to generate trade‑specific quantity lists, which are then reviewed by human specialists to ensure 100% accuracy. The final deliverable includes a detailed, trade‑segmented takeoff and a visual audit trail that maps each quantity back to its source on the plans. This workflow eliminates the need for users to learn specialized software, accelerates turnaround compared to manual methods, and provides reliable data for faster, more competitive bidding.
