Quick Answer: Paving takeoff is measuring every paving area off the scaled site plan, sizing asphalt in tons and concrete pavement in cubic yards at the section depth, sizing aggregate base in cubic yards, and measuring striping, curb, and gutter in linear feet. CyanBuild reads the paving sheets, computes each layer from the area and the section depth, and reports the line items with a confidence flag on every line so your estimator knows what to verify.
Paving takeoff is the process of measuring every quantity on a paving plan in the units your trade bills on. Done by hand it means tracing areas with a scale wheel and converting square feet to tons and cubic yards in a spreadsheet, which is slow and error prone. AI reads the same drawings in seconds and reports the same quantities, with the math shown for every number so your bid is defensible.
CyanBuild measures paving quantities off the scaled PDF, DWG, or image. The result is a line item takeoff tied back to the sheet and location it came from, so your order is accurate and your bid holds up when the GC checks your numbers.
What Trade Specific Takeoff Means for Paving
Paving sits in CSI Division 32, Exterior Improvements, and the trade specific part is that a paved area carries three or four layers and each layer bills in a different unit. The same parking lot is subgrade preparation in square feet, aggregate base in cubic yards, asphalt in tons, and striping in linear feet. Trade specific takeoff has to measure the area once and then derive every layer from it, using the section depth from the detail. Generic area takeoff software gives you the square footage and stops there, which leaves the estimator to convert to tons and cubic yards by hand.
Trade specific also means the takeoff reads the paving section, not just the plan. The plan shows where the pavement goes. The section and the notes tell you how deep it is and what it is made of. A takeoff that only reads the plan misses the depth, and without the depth you cannot compute the tons or the cubic yards. Good paving takeoff software pulls the section depth off the detail and applies it to the area it measured.
What Counts on the Drawings
Paving quantities live on the site plan, the paving plan, the paving details, and the striping plan. The site plan shows the paved areas at a small scale. The paving plan shows them at a larger scale with the section callouts. The paving details give the depth and the material for each section. The striping plan shows the stalls, the arrows, and the crosswalks in linear feet. A complete takeoff reads all of them.
What you are counting and measuring:
- Asphalt pavement in tons, computed from the area in square feet, the section depth in inches, and the unit weight of the mix.
- Concrete pavement in cubic yards, computed from the area and the slab depth, with joints and reinforcement counted separately.
- Aggregate base in cubic yards, computed from the area and the base depth called out in the section.
- Subgrade preparation and proof roll, in square feet, under every paved area.
- Curb and gutter, in linear feet, with the cross section pulled from the detail.
- Striping and pavement markings, in linear feet, with stalls and symbols counted.
- Geotextile and separation fabric, in square feet, under the base where the detail calls for it.
What Good Takeoff Software Does for This Trade
Good paving takeoff software measures the area off the scaled drawing and then layers the section depth on top of it. It pulls the depth and the material off the paving detail, computes the tons or the cubic yards from the area, and shows the math so your estimator can spot a bad scale read. It handles the conversion from square feet of asphalt at a given depth to tons, using the unit weight of the mix, and it does the same for aggregate base and concrete. It measures the curb and gutter in linear feet off the edge of pavement, and it counts the striping stalls and the symbols off the striping plan.
The software should also handle the overlapping layers. The same area carries subgrade, base, and pavement, and each one is a separate line item. The takeoff should measure the area once and report each layer, not make the estimator trace the same lot three times. And it should handle the patches and the ramps, small areas that get missed in a hand takeoff because they do not show up at the small scale.
Must Have Features
- Area measurement off scaled PDF, DWG, and image files, with calibration for sheets that come in at an odd scale.
- Section aware takeoff that pulls the depth and material off the paving detail and applies it to the area.
- Unit conversion built in: square feet at a given depth to tons of asphalt, cubic yards of base, and cubic yards of concrete.
- Layered reporting on the same area, so subgrade, base, and pavement each get their own line.
- Curb, gutter, and striping measured in linear feet, with stalls and symbols counted.
- Confidence flags on every line, so your estimator knows which areas came straight off the sheet and which need a second look.
- Takeoff tied back to the sheet and the location, so the GC can trace any number back to the plan.
- Export to Excel and PDF in the format your bid sheet expects, with areas, tons, and cubic yards in separate columns.
What to Watch Out For
The trap in paving takeoff is the depth. Designers call out the asphalt depth in the section detail, not on the plan, and a takeoff that only reads the plan reports square feet instead of tons. Software that does not read the section detail leaves the estimator to look up the depth and convert by hand. Ask whether the tool pulls the section depth off the detail and applies it to the area, or whether it only reports square feet.
The second trap is the scale. Paving plans are often plotted at a small scale, and a bad calibration turns a 10 percent error in area into a 10 percent error in tons. Ask how the tool handles scale calibration and whether it lets you check the area against a known dimension on the sheet. Ask how it handles the patches, the ramps, and the islands, which are easy to miss. Ask how it handles the striping, because the stalls and the symbols are a count item hiding inside a linear foot takeoff. And ask how it tracks revisions, because paving plans change between the permit set and the issue for construction more often than people realize.
How CyanBuild Fits
CyanBuild reads paving plans, paving details, and striping plans in PDF, DWG, DXF, or image format. It measures every paved area off the scaled drawing, sizes asphalt in tons and concrete pavement in cubic yards at the section depth, sizes aggregate base in cubic yards, and measures striping, curb, and gutter in linear feet. Each line carries a High, Medium, or Low confidence flag, and low confidence lines show the math so your estimator verifies in seconds. The takeoff exports to Excel and PDF with every quantity tied to its sheet and location, ready for pricing and bid.
Putting It Together
Paving takeoff is an area with layers. The same parking lot is subgrade, base, pavement, and striping, each billed in a different unit, and the depth that ties them together lives in the section detail, not the plan. Generic area takeoff software gives you square feet and stops there. Trade specific paving takeoff software reads the section, computes tons and cubic yards from the area and the depth, and reports each layer as its own line item with the math shown. Run a sample sheet through any tool you are considering and check whether the output matches the way your bid sheet is built. If you have to look up the depth or convert square feet to tons by hand, the tool is not doing the takeoff for your trade.
