"Counted a 40-page office building in 12 minutes. I spot-checked three floors—numbers were solid. Saved me 6+ hours I would've spent with a highlighter. That's time I can spend bidding other jobs."

Why Low Voltage Contractors Use TakeoffBuilder
Low voltage takeoffs involve counting hundreds of small symbols across dozens of pages. Data drops, cameras, sensors—every symbol matters, and manual counting takes hours. TakeoffBuilder's AI identifies and counts these components in minutes, giving you a starting point to review rather than staring at plans from scratch.
- AI counts network drops, security devices, and A/V equipment from plans
- Initial counts ready in 10-15 minutes for your review
- Toggle and adjust quantities based on your project knowledge
Stop Counting. Start Adjusting.
You don't need AI to do everything. You need AI to do the tedious counting so you can focus on the decisions that actually require your expertise. Review flagged items, adjust for project-specific conditions, add your markup—then export to your estimating software.
- AI flags uncertain items for your review—no surprises
- Add 10-12% markup with toggles—adjust based on job conditions
- Export to Excel or CSV for your existing workflow
What You Get From Every Takeoff
Complete material counts, organized by system and zone. Export formats that work with your existing estimating software.
Component Counts by Zone
Every device counted and organized by floor, room, or zone. Network drops by type (Cat6, Cat6a, fiber), cameras by style, speakers by ceiling/wall mount. Quantities you can verify at a glance.
- Organized by floor, zone, or system type
- Flagged items marked for manual review
- Editable toggles to adjust quantities
Cable Footage & Pathways
Estimated cable runs from endpoints to equipment rooms. The AI calculates pathway routing and provides footage estimates you adjust based on actual routing conditions and vertical rise.
- Horizontal and vertical cable run estimates
- Conduit and pathway routing suggestions
- Adjust for risers, drops, and actual job conditions
Equipment & Hardware Lists
Switches, patch panels, racks, power supplies, and control equipment identified from equipment schedules and single-line diagrams. Organized by location with power requirements.
- Network switches and POE injectors
- Patch panels, cable management, and racks
- Power supplies and backup battery systems
Excel, CSV, & PDF Export
Download your counts in Excel or CSV for import to your estimating software. Get annotated PDFs showing what the AI counted. Export to JSON for custom integrations. Your data, your format.
- Excel and CSV for estimating software import
- Annotated PDF with AI markup for verification
- JSON export for custom integrations
What Makes Low Voltage Counts Accurate
AI accuracy comes from understanding construction context, not just symbol matching. Here's what we track to ensure reliable counts.
-
Symbol Library 1,091 low voltage symbol definitions across data/comm, security, A/V, and fire alarm systems. The AI recognizes standard and custom symbols from legend references.
-
Context Understanding Claude AI understands what components mean in context—a data drop in a classroom isn't the same as one in an equipment room. Context awareness catches what pattern matching misses.
-
Smart Flagging Items with lower confidence get flagged automatically. You know exactly what needs human eyes. This hybrid approach means you trust the bulk count and focus your expertise on edge cases.
-
Consistent Methodology AI doesn't get tired at hour 30 of counting. Same accuracy on the first takeoff and the hundredth. No variance between estimators or shifts in interpretation.

Low Voltage Contractors Using TakeoffBuilder

6 reviews
"The flagging system is smart. It caught two camera locations I would've missed in a parking structure detail. I review the flags, adjust quantities for ceiling height, export to Excel. Works exactly how I need it to."
"First takeoff I was skeptical. Compared it section by section against my manual count—96% match. Now I trust the bulk count and just verify the complicated zones. Cut my bid prep time in half."
"The Excel export drops right into our pricing spreadsheet. No reformatting, no manual entry. That alone saves us 30 minutes per bid. The counts are consistently accurate—we add our standard markup and move on."
"We're bidding 3x more jobs now because takeoffs don't bottleneck us. Upload plans in the morning, have counts by lunch, bid goes out same day. That speed advantage wins us work competitors don't have time to chase."
"I was paying $400 for outsourced takeoffs and still spending 2 hours verifying them. Now I get AI counts for $15, spend 30 minutes reviewing, and have more confidence in the numbers. No-brainer."
Low Voltage Takeoff Questions
Common questions from data/comm, security, and A/V contractors.
Does it work on security camera layouts?
Yes. The AI counts cameras, card readers, door contacts, motion sensors, and control panels from security drawings. It organizes devices by zone with power and cabling requirements. You review and adjust based on your installation requirements.
- Counts cameras by type (dome, bullet, PTZ)
- Identifies access control devices and alarm sensors
How accurate are cable run estimates?
The AI calculates horizontal runs from endpoints to equipment rooms based on plan routing. You adjust for vertical rise, ceiling height, and actual pathway conditions. Most contractors add 10-15% to AI estimates for real-world routing—the toggles make this instant.
- Horizontal routing calculated from plan pathways
- You adjust for risers, drops, and ceiling conditions
Can it count network drops by cable type?
Yes. The AI differentiates Cat6, Cat6a, fiber, and phone drops based on plan legends and annotations. You get counts organized by type so you can order correct cable spools and termination hardware.
- Separates Cat6, Cat6a, fiber, and voice drops
- Organized by floor or zone for installation planning
What plan types work best for low voltage?
We work best on commercial data/comm drawings, security layouts, and A/V system plans with standard symbols. Residential low voltage and custom symbols work but may need more manual review. Cleaner PDFs with clear legends produce more accurate initial counts.
- Commercial plans with standard symbols perform best
- Custom symbols may need manual review and adjustment
How much does a typical low voltage takeoff cost?
Typical 30-50 page security or data/comm set uses 3 credits ($15 at standard pricing). Larger projects with multiple systems might use 5-7 credits. First takeoff under 20 pages is free so you can test on your own plans. Credits never expire.
- 30-50 page sets typically cost 3 credits ($15)
- First takeoff free on plans under 20 pages
Do I still need to verify the counts?
Yes. We recommend spot-checking, especially on your first few takeoffs. The system flags items with lower confidence for review. Most contractors find they can trust the bulk count and just verify flagged items and complicated zones—that's still hours saved compared to starting from scratch.
- Spot-check sections to build confidence in AI counts
- Focus review on flagged items and complex zones
