📋 About Joist AI

Joist AI is an AI-powered estimating and takeoff platform built for construction contractors, subcontractors, and material suppliers who need to produce accurate bids quickly. Traditional takeoff work — measuring lengths, counting fixtures, and quantifying materials from blueprints — can take days and remains error-prone even for experienced estimators. Joist ai automates the measurement and quantification pipeline using computer vision models trained on construction drawings, turning PDF plans into structured material lists in a fraction of the time while maintaining the accuracy needed for competitive bidding.

⚡ Key Features of Joist AI

Automated Takeoff from Drawings

Joist ai ingests PDF construction drawings and identifies scope items like walls, doors, windows, fixtures, and finishes using computer vision models trained on construction documents. The system quantifies items automatically, producing lengths, areas, counts, and volumes as appropriate. This reduces takeoff time from days to hours for most projects. Accuracy matches or exceeds manual takeoff for standard scope packages.

Integrated Drawing Viewer

A built-in drawing viewer lets estimators review AI-generated takeoffs overlaid on original plans, with clear visualization of what was detected and quantified. Estimators can correct missed or misclassified items, add manual measurements, and confirm quantities before pricing. The viewer supports common drawing formats and multi-sheet projects. This review workflow is essential for estimator trust in AI-generated output.

Scope Package Organization

Takeoffs are organized by scope package, trade, floor, or custom categorization to match how estimators price work. This structure fits naturally with how subcontractors bid specific scopes rather than whole projects. Custom categorizations can be saved as templates for repeat use across similar projects. Output structure supports both prime contractor and specialty trade workflows.

Pricing and Cost Database

Quantified items can be priced against internal cost databases, material supplier catalogs, or published pricing references to produce complete estimates. Historical project data informs cost estimates for custom items without published pricing. Markup rules apply labor burden, overhead, and profit percentages per scope. Finished estimates can be exported for submission or further processing in downstream tools.

Collaboration and Version Control

Multiple estimators, subcontractors, and project stakeholders can collaborate on the same takeoff project with role-based access and edit locks that prevent overwrites. Version history captures every change for audit and rollback. Comments and annotations on specific items facilitate review and approval workflows. Collaboration features support both internal teams and external subcontractor bid packages.

Integrations with Estimating Software

Exports to Sage Estimating, ProEst, Bluebeam, Excel, and other major tools let joist ai fit into existing estimating and project management workflows without forcing a full platform change. Output formats preserve scope structure and quantification for downstream use. Integration reduces the adoption risk of adding a new tool to established workflows. APIs support custom integrations into ERP and accounting systems.

Specialty Trade Modes

Specialized modes for electrical, plumbing, HVAC, drywall, flooring, and other common trades apply trade-specific detection logic and quantification rules. Specialty contractors benefit from output tuned to their specific deliverables rather than generic measurements. Coverage expands over time as trade-specific feedback improves detection models. This focus distinguishes the platform from generic blueprint OCR tools.

🎯 Use Cases for Joist AI

Generate fast, accurate takeoffs for bids where turnaround time determines whether a contractor can even participate. Contractors use joist ai to bid more jobs per week without growing estimating headcount, improving hit rates through volume alone. Quantify materials across large multi-floor commercial projects where manual takeoff would consume multiple estimators for days. Enterprise contractors use the platform to keep bid timelines reasonable even for complex RFPs. Support specialty trade estimating for electrical, plumbing, HVAC, drywall, and other trades where scope-specific quantification matters. Trade contractors use specialized modes to produce deliverables that match their trade's estimating conventions. Improve bid accuracy by reducing quantification errors that cause margin erosion or disputes mid-project. Project executives use consistent, auditable takeoffs to protect against the all-too-common under-bid that damages profitability. Centralize estimating knowledge across a contractor's organization, with saved templates, cost databases, and scope categorizations that new estimators can use from day one. Estimating directors use this to reduce onboarding time and enforce consistency. Coordinate with subcontractor bids by sharing AI-generated takeoffs as the canonical scope definition. General contractors use this to reduce ambiguity in sub-bid packages and minimize change orders caused by scope misinterpretation.
