Blueprint Takeoff and Estimating Services
Send us the drawings you actually have. A clean PDF set, a scan of a printed blueprint, a DWG export, or photographs of a marked-up set on a job trailer table — we work from all of them, and we tell you honestly what each one can support before you pay for anything.
Get a Free QuoteWhat We Can Work From
PDF plan sets. The normal case. Vector PDFs are ideal — we can verify scale against known dimensions and measure directly off the geometry.
Scanned prints. Common on renovation and older commercial work where the only record is a paper set. Scan quality determines what is possible, and we will tell you which before you commit.
DWG and DXF files. Native CAD geometry, the most accurate source available, and the only one where scale is not in question.
Photographs of printed drawings. Not ideal, and frequently all that exists. Whether we can use them depends on whether the sheet is square to the camera, whether the scale bar and title block are legible, and whether dimension strings are readable.
Partial sets, superseded sets, and sets with addenda. Tell us which revision governs. If you do not know, we will tell you what we found and which sheets conflict — we will not silently pick one.
Scale Verification — Why This Matters
Most takeoff errors on a scanned or photographed set are not measurement errors. They are scale errors, and a scale error is invisible until the quantities are already wrong.
A drawing printed at “half size”, scanned at an angle, or photographed from three feet away is no longer at the scale in its title block. Measuring it as though it is produces quantities that are internally consistent and completely wrong — every number in proportion to every other, and all of them off by the same factor.
We calibrate every drawing against a known dimension before measuring — a dimension string, a door width, a column grid spacing, a scale bar. Where the drawing offers nothing to calibrate against, we say so and flag those quantities as unverified rather than presenting them at the same confidence as the rest.
That distinction goes in the assumptions schedule on every blueprint takeoff we produce, sheet by sheet.
Drawing Sources and What Each Supports
What a source can support is not a matter of opinion. Below is what we can measure from each, and where each one stops being reliable.
What We Can and Cannot Get From a Poor Scan
Everyone accepts PDFs. Almost nobody tells you what happens when the file is bad, so here it is.
Usually workable. Overall areas and footprint — floor area, roof area, paved area. Counts of clearly drawn items such as doors, windows, fixtures and columns. Linear runs of walls and major elements. Anything with a dimension string printed next to it.
Difficult but often possible. Small-scale details where line weights have merged. Hatched or shaded areas where the pattern has degraded. Schedules where text has blurred — sometimes recoverable by cross-referencing the plans against the legend.
Not reliably possible. Measurements from a sheet with no verifiable scale reference. Distinguishing similar line weights in a heavily compressed scan. Reading a schedule that is genuinely illegible. Anything on a sheet photographed at an angle steep enough to distort geometry.
You find out at quote stage, not after. We tell you which category your set falls into before you pay. If half your sheets are unusable, you should know that before you commit — and if the readable portion is not worth buying a takeoff for, we will say that too.
How We Calibrate Scale
Calibration is done per sheet, not per set, because scanners, printers and cameras do not distort every page identically.
A printed dimension string first. The most reliable reference available on a degraded set. A dimension written on the drawing was correct when it was drawn, and it stays correct through any uniform scaling — which makes it the calibration source of choice.
Column grid spacing second. Structural grids are dimensioned and repeat across the sheet, so they let us check calibration in two directions and catch non-uniform stretch that a single dimension would miss.
A known standard element third. A door leaf width, a stair tread, a parking stall. Weaker than a printed dimension because it assumes a standard was followed, so it is used as a cross-check rather than a primary reference and recorded as such.
The scale bar last. Counter-intuitive, but a scale bar is only as good as the reproduction — it scales with the distortion it is supposed to reveal. Useful for confirming a calibration, unreliable as the sole basis for one.
Cross-checking in both axes. A sheet can be stretched horizontally and not vertically, particularly on a roller scan. Calibrating one axis and assuming the other is where uniform-looking errors come from, so both are verified independently.
Recorded per sheet in the deliverable. Every sheet's calibration source is written down — what we measured against, and the factor applied. Where a sheet could not be calibrated, that is written down too, and the quantities from it are segregated rather than blended in.
What You Receive
- An editable Excel workbook with quantities by division
- A marked-up set showing every measurement against the drawing it came from
- A scale verification note per sheet — what we calibrated against, or that we could not
- An assumptions and exclusions schedule, with unverified quantities flagged separately
- A legibility report where the set was poor, listing sheets and areas we could not read
What We Need From You
Less than you might expect. Send the set as it is — resist the urge to re-scan or clean it up first, because the original is usually better than a second-generation copy.
- Whatever drawings exist — PDF, DWG, scans, photographs or a ZIP of all of it
- The highest-resolution version you have, rather than a compressed email copy
- Which revision governs, if you know; all of them if you don't
- Any specification, schedules or addenda, even partial
- A dimension you know to be correct, if the set has none printed on it
- Which divisions you need measured, and whether you want quantities only or pricing
- Whether any part of the building has been built differently from the drawings
What Moves the Price
Drawing quality, more than on any other service. A clean vector PDF is faster than a skewed scan of a 1987 print, and the quote reflects that rather than hiding it in an average. This is the one service where the condition of the input is a primary price driver.
How much calibration the set needs. One calibration per sheet across forty sheets is real work, and a set where half the sheets have no printed dimension needs cross-referencing before measurement can start at all.
Revision conflicts. Multiple overlapping revisions with no clear governing set means reconciling sheets against each other before anything is measured. It is worth doing and it takes time.
Division count and project size. The same drivers as any takeoff — how much there is to measure, in how many scopes.
Whether a legibility report is needed. On a poor set, documenting what could not be read is part of the deliverable and part of the effort. On a clean set it costs nothing because there is nothing to report.
Why Scanned-Set Takeoffs Go Wrong
Title block scale trusted. The single most common failure. A sheet marked 1/8″ = 1′-0″ that was printed at half size is now 1/16″, and nothing on the drawing says so. Every quantity comes out at a quarter of the area it should be, and all of them agree with each other.
One calibration applied to a whole set. Different sheets scan differently, especially on a roller feed or when a set was assembled from more than one source. Calibrating the first sheet and measuring the rest at that factor propagates an error that looks like consistency.
One axis calibrated, the other assumed. Non-uniform stretch is common and invisible. Areas come out wrong while linear dimensions in one direction look right, which is the hardest version of this error to notice downstream.
Unverified quantities presented at full confidence. If a sheet could not be calibrated, its quantities are estimates, not measurements. Blending them into the same column as verified quantities hides which numbers you can rely on.
Illegible scope quietly guessed. When a schedule cannot be read, the honest output is an exclusion and a note. A plausible number inserted in its place is worse than a gap, because a gap gets asked about and a number does not.
Superseded sheets measured. Old and current sheets look identical at a glance, and revision clouds do not survive a bad scan. Measuring a superseded sheet produces a correct takeoff of the wrong building.
How It Works
1 · Send your plans. PDF, DWG, DOC, images or ZIP, up to 100MB per file. Tell us the scope you need covered and any format you want it delivered in.
2 · Get your quote. A flat price for the scope with a delivery date, confirmed in writing. There is no charge for the quote and no obligation once you have it.
3 · Approve. Nothing starts until you confirm. If we think a different service would suit you better, this is the point at which we say so.
4 · We calibrate and measure. Scale verified per sheet against a printed dimension before any measurement is taken, then digital takeoff with every measured area shaded on the set and every calibration source recorded.
5 · Delivery. The workbook, the marked-up plan set and the assumptions schedule, with a walkthrough of anything that looks off to you.
How Pricing and Turnaround Work
Priced per project from the set. Drawing quality is one of the things that moves the price — a clean vector PDF is faster than a skewed scan of a 1987 print, and the quote says so.
What drives the quote: drawing condition, how much calibration the set needs, revision conflicts, division count, project size and turnaround.
The price and the delivery date are fixed in writing before you approve anything. There is no hourly billing, no retainer and no monthly minimum, and we do not start work on an open-ended basis.
Tools and Standards
Quantities, rates and assemblies are read against the published references that govern this work. Where a project specification conflicts with any general reference, the specification governs:
- CSI MasterFormat — the division structure quantities are organized against
- Per-sheet scale calibration against a printed dimension, recorded in the deliverable
- Two-axis calibration checks to catch non-uniform reproduction distortion
- Explicit segregation of verified and unverified quantities
- A per-sheet legibility report where any part of the set could not be read
- The governing revision confirmed with you before measurement, never assumed
- Your own template and unit preferences, where you provide them
Frequently Asked Questions
Can you work from a photograph of a blueprint?
Often, yes. It depends on whether the sheet is square to the camera, whether the title block and any dimension strings are legible, and whether there is something to calibrate scale against. Send them and we'll tell you before you pay.
What if the drawings have no scale bar?
We calibrate against a known dimension instead — a dimension string, a standard door width, a column grid. If there is nothing to calibrate against, we say so and flag those quantities as unverified.
Our set is old and hand-drawn. Can you use it?
Frequently. Hand-drawn sets are often more legible than a bad digital scan, because line weights are heavier and dimension strings are usually present. Send a sample sheet and we'll assess it.
We have multiple revisions and don't know which is current.
Send them all. We'll identify which sheets conflict and tell you what we found. We will not silently pick one.
Is a blueprint takeoff different from a regular takeoff?
The output is identical. The difference is the input — this service exists because working from degraded or non-digital drawings needs scale verification and honest reporting about what could not be read.
What if you can't read part of the set?
You get a legibility report listing exactly which sheets and areas were unreadable, and those scopes are excluded rather than guessed. If it's a large enough portion, we'll tell you at quote stage that the takeoff isn't worth buying.
Should I re-scan the drawings before sending them?
Usually not. A second-generation copy loses line weight and detail, and a photograph of the original print is often better than a rescan of a scan. Send the best original you have and let us judge it.
Can you price the work as well, or only measure it?
Either. Quantities alone if you have your own cost data, or a fully priced estimate — with unverified quantities flagged in both cases, so you know which lines are firm before you bid.
Every Division, Priced the Way the Spec Is Organized
A cost estimate is only as good as the trade knowledge behind each line. These are the trades we quantify and price, grouped the way a specification is.
Project Types We Estimate
Cost drivers change with the building type. Each sector page covers what moves a number on that kind of work.
If You Need Something Narrower
A full priced estimate is not always what the job calls for. These are the adjacent services, including the takeoff-only options that cost less.
We Estimate in All 50 States
Labor rates, wage rules and material costs are priced to the job’s market, not to a national average. Pick a state to see how that works locally.
