Built for US Concrete Construction. Estimated with AI. Validated by Engineers.
Built for US Concrete Construction
We speak your language
No conversion hassles. No metric confusion. Built for how US concrete contractors work.
Engineer-Validated Results
Every takeoff reviewed by licensed professionals
We don't just rely on AI—we validate it:
Multi-stage validation process:
- Conservative assumptions when drawings are ambiguous
- Cross-validation against drawing notes and specifications
Full transparency:
- Every quantity traces to source drawing and sheet number
- Notes explain all assumptions made
- Complete audit trail for your review
Quality you can trust:
- Validated against ACI 318 and IBC standards
- Checked for constructability and practicality
- Peer-reviewed for consistency across elements
No Software to Learn
Upload plans. Get results. That's it.
What you DON'T need:
- No new software to buy
- No training courses required
- No complex integrations to manage
- No changing your workflow
What you DO get:
- Simple web upload
- Results in formats you already use (Excel, Revit)
- Works alongside your existing estimation tools
- Keep using Procore, Sage, CMiC—we complement, not replace
Your team can start using ConstructAI in the next 10 minutes.
Accuracy Built on Validation, Not Just AI
Why we combine AI with human expertise
AI is fast and consistent—but construction drawings have nuances, ambiguities, and project-specific details that require human judgment.
Our hybrid approach:
- 1 AI handles the heavy lifting: Extracts 90% of quantities automatically
- 2 Engineers validate the critical 10%: Reviews complex seismic details, unusual connections, ambiguous notes
- 3 You get the best of both: Speed of AI + reliability of human expertise
What gets flagged for engineer review:
- Seismic boundary elements and special detailing
- Non-standard rebar configurations
- Conflicting information between drawings
- Missing or unclear details
- Any extraction below confidence threshold
Result: Takeoffs you can confidently bid on, knowing they've been validated by professionals who understand construction.
Is ConstructAI Right for Your Projects?
We're laser-focused on reinforced concrete structures for US contractors. If you fit the criteria below, we're built for you.
IDEAL FOR ✓
Company Type & Role:
- General contractors bidding on concrete projects (1-20 stories)
- Concrete subcontractors preparing estimates
- Estimators at peak load who need to submit multiple bids simultaneously
- Companies struggling to find skilled concrete estimators
- Teams already assigned to multiple projects
- GCs who need to increase bid capacity without hiring
- Firms looking to improve estimation accuracy and reduce material waste
- Design-build firms needing BIM coordination from day one
Project Characteristics:
- Reinforced concrete structures (cast-in-place, post-tensioned)
- Office buildings (1-20 stories)
- Residential (mid-rise, 3-20 stories)
- Retail and mixed-use developments
- Parking structures
- Warehouses and distribution centers
- Light industrial buildings
- Projects in the United States
Timeline & Workflow:
- Need results in 5-15 days
- Prefer to focus on bidding strategy over manual takeoffs
- Value engineer-validated results
- Want to bid more projects with the same team
NOT IDEAL FOR ✗
Project Types We Don't Support Yet:
- Single-family residential
- High-rises over 20 stories (coming 2026)
- Bridges and infrastructure (roadmap TBD)
- Projects outside the US (we're US-only during beta)
Structural Systems We Don't Support Yet:
- Structural steel buildings
- Wood framing (light or heavy timber)
- Masonry as primary structure
Other Trades We Don't Support Yet:
- MEP systems (mechanical, electrical, plumbing)
- Architectural finishes
- Site work and civil
- Multi-trade comprehensive takeoffs
Wrong Workflow:
- Need results in 24 hours (we prioritize accuracy over extreme speed)
- Looking for self-service software to run internally (we're currently offering a service during our beta phase, web app launch coming Q1 2026)
- Want to improve your company's internal extraction workflow? Consider our ConstructAI Embedded solution .
WHY SO FOCUSED?
We're building the most accurate concrete takeoff service in North America. That requires deep specialization in one structural system, one set of codes (ACI 318, IBC), and one market (US construction).
Our philosophy: Be excellent at one thing rather than mediocre at many.
Steel, precast, and other trades will come—but only after we've perfected reinforced concrete. Read Our (Not-So-Secret) Master Plan
