Quick Answer: A fencing takeoff pulls every fence run in linear feet, counts posts by type, sizes gates, and figures concrete for post foundations, all off the site and fence plans. CyanBuild reads your fencing drawings, measures each run off the scaled site plan, sizes line and terminal posts at the spacing called out in the notes, counts gates by type and width, and sizes the concrete for each post hole, so your bid covers the full material and hardware package with the math shown on every line.
Fencing takeoff is the process of measuring every quantity on a fencing plan, the units your trade actually bills on. AI reads the same sheets in seconds and reports the same quantities, with the math shown for every number so your estimator can defend the bid. The result is a line item takeoff tied to the sheet and location it came from, so your bid is defensible and your order is accurate.
What Trade Specific Takeoff Means for Fencing
Fencing falls under CSI Division 31 00 00, Earthwork, and Division 32 00 00, Exterior Improvements, and on most commercial sets it shows up on the site civil sheets rather than the architectural sheets. That matters because the drawing language is different. It is a long linear assembly made of fabric or panels, posts at a fixed spacing, rails between the posts, and hardware at every connection, plus a gate assembly wherever the run is interrupted. A trade specific takeoff understands that linear feet of chain link is not the same as linear feet of wood privacy fence, because the material, the post spacing, and the hardware behind each LF are different.
Trade specific takeoff also understands the site context. A fence line that follows a sloped grade has to be stepped or racked, which changes the post count and the fabric cut list. A fence along a property line needs terminal posts at every change of direction, every gate, and every end. Generic takeoff tools that only measure line length miss all of that. A trade aware takeoff reads the notes and the symbol legend, not just the geometry, and sizes the bill of materials accordingly.
What Counts on the Drawings
On a typical fencing plan set, the quantities you need to pull are: linear feet of each fence type (chain link, wood, vinyl, ornamental steel or aluminum), post count broken down by line, terminal, corner, and gate posts, post spacing from the notes, top rail and mid rail LF, tension wire LF, fabric or panel LF by height, gate count by type and leaf width, gate hardware sets, and post concrete volume per post and total.
Site plans carry the fence line in plan view, with the fence type labeled and gates shown as breaks in the line. The fence detail sheet gives the post spacing, the post size by fence height, the rail size, and the concrete diameter and depth. When there is no detail sheet, the estimator falls back on the manufacturer standard detail, which is where a lot of fencing bids lose money, because the post count and the concrete volume are assumptions, not measurements.
What Good Takeoff Software Does for This Trade
Good fencing takeoff software reads the scaled site plan, snaps the fence line to the geometry, and reports LF by fence type, not one undifferentiated length. It reads the post spacing off the notes and divides the run length to size the post count, calling out line and terminal posts separately. It counts gate symbols on the line and reports each by type and leaf width, because a 4 foot pedestrian gate and a 16 foot double drive gate carry very different hardware and material costs. It sizes the post foundation concrete from the detail diameter and depth and multiplies by the post count, so you are not ordering concrete on a guess.
A capable tool also handles the things that quietly eat margins. It accounts for cuts at corners and ends, where a run stops short and the fabric has to be trimmed, and it flags runs that cross sloped grade, where posts may need to be longer or the fabric racked. And it keeps every quantity tied to the sheet and the station it came from, so when the fence line moves, you can see exactly what changed instead of redoing the whole site.
Must Have Features
- Scaled linear measurement. The tool has to read the scale bar and report LF in feet and inches, not pixels. Without true scale, the post count and the fabric order are guesses.
- Post count by type from spacing. Line, terminal, corner, and gate posts are different costs. The tool has to separate them using the spacing in the notes and the gate locations.
- Gate count by type and width. A takeoff that lumps all gates together misses the difference between a pedestrian gate and a double leaf equipment gate.
- Concrete volume per post. The tool has to size it from the detail diameter and depth and multiply by the post count.
- Material list by fence type. Chain link, wood, vinyl, and ornamental steel have different bills of materials. The tool has to keep them separate so you can price each correctly.
- Confidence flags on every line. Every count should carry a High, Medium, or Low confidence flag, with the math shown on low confidence items so your estimator can verify in seconds.
- Export tied to sheet and location. The takeoff has to leave the tool in Excel or PDF, with every quantity traceable to where it came from.
What to Watch Out For
Most generic takeoff tools measure line length and stop there. That is fine for pricing chain link fabric by the foot, but it misses the post count, the post type split, the gate hardware, and the concrete, which are typically more than half the material cost on a fencing job. If the tool you are evaluating only reports one LF number per run, you are still going to be counting posts by hand, and that defeats the point of paying for software.
Watch for tools that count gates as a single number without type or width. A takeoff that says "6 gates" is not useful when two are 16 foot double drive gates and four are 4 foot pedestrian gates. The same goes for post spacing. If the tool uses a default spacing instead of reading the notes, the post count will be wrong on every job that does not match the default, and on fencing most jobs do not match the default.
Watch for tools that ignore slope. A fence line on a 20 percent slope racks the fabric and may step the posts, which changes the cut list and the post length. A tool that treats the plan view length as the actual fabric length will under order on sloped runs. And watch for tools that do not tie quantities to the sheet. When the plan set is revised, you want to see what moved, not redo the whole site.
How CyanBuild Fits
CyanBuild reads your fencing sheets, measures each run off the scaled site plan in linear feet by fence type, sizes line and terminal posts at the spacing from the notes, counts gates by type and width, and sizes concrete for each post foundation from the detail. The materials AI identifies include chain link, wood, vinyl, and ornamental steel or aluminum fencing, posts by type, top and mid rails, tension wire, fabric, gates and gate hardware, and post foundation concrete. Each line item carries a confidence flag so your estimator knows which runs to verify. Export to Excel or PDF, with every quantity tied to its sheet and location, ready for pricing and bid.
Putting It Together
A fencing bid is only as good as the bill of materials behind it. When the takeoff lumps every run into one LF number, you are left to count posts and gates by hand and size concrete on a rule of thumb. When the takeoff splits the run by fence type, sizes the posts from the notes, counts the gates by type, and sizes the concrete from the detail, the bid is defensible and the order is accurate. That is the gap CyanBuild is built to close.
