Plan reading · Blueprint estimating
Blueprint estimating from plans that were never meant to be easy to read
Not every project arrives as a clean, vector PDF. Some come as faded scans of a 1980s set, photographed sketches or an architect's partial drawings with half the details missing. Our estimators read the blueprint the way a superintendent would, scale it from what is printed, reconcile the sheets against each other and send you written questions about everything that cannot be priced from the page.

Process
How our estimating process works
Four steps from upload to a bid-ready estimate, with a senior estimator signing off before anything leaves our desk.
- 1
Upload plans and scope
Send your drawings, specifications and bid invitation through the secure upload form. We confirm scope, deadline and a fixed price within two business hours.
Then step 2
- 2
Digital quantity takeoff
Estimators measure every item from calibrated plans in Bluebeam and PlanSwift, color-coding each layer so quantities can be traced back to the drawing.
Then step 3
- 3
Pricing and labor
Quantities are priced with location-adjusted material costs, crew productivity rates and equipment, then marked up to your overhead and profit targets.
Then step 4

Senior review and delivery
A second estimator audits quantities and pricing, documents assumptions and exclusions, and delivers your Excel workbook, PDF summary and marked-up plans.

Overview
Reading the plans before measuring them
Blueprint estimating begins with plan reading. Before any quantity is measured, the estimator walks the set: the architectural plans for layout and finishes, structural sheets for foundations and framing, then mechanical, electrical and plumbing drawings for the systems that run through the walls. Cross-referencing one discipline against another is how coordination conflicts, such as a duct through a beam, get caught before bid day. We also read general notes and title block revisions first, since a single note such as typical footing steps or exterior finish by owner often changes the price.
Older and informal plans demand extra care. Scanned blueprints shrink or stretch in the copying process, so scale bars are verified against dimensioned walls and grid lines. Hand-drawn sketches lean on written dimensions, not scale. Where a set is incomplete, we price what is shown, state the assumption for what is not, and carry an allowance with a clear note explaining what drawing would replace it. Every assumption is attributed to a sheet or note, so when the real answer arrives you can see exactly which line to correct rather than reworking the estimate.
The deliverable is a clean estimate paired with a plan-reading memo that lists scale checks, conflicts, missing sheets and every open question. That memo becomes your RFI list, protecting your bid from scope you could not see and giving the architect or owner a concise set of items to resolve. Pricing then resumes on a firm footing, with the memo reused as the transmittal that explains the basis of the bid to your own reviewers, the owner or the design team.

Why LEEDS
Why contractors switch to LEEDS
An estimating desk that behaves like an extension of your team, not a software subscription.
- 01
Estimators who started in the field read plans like a superintendent, noticing what the drawing implies but does not say.
- 02
Every scanned sheet is verified against a dimensioned element, so scanner distortion never silently inflates or shrinks your quantities.
- 03
Hand-drawn and incomplete sets are welcome, with a clear allowance and assumption stated for every item the page leaves open.
- 04
Cross-discipline reading catches conflicts, such as duct runs through beams before they become change orders on your job.
- 05
An RFI-ready question log comes with every estimate, written so an architect can answer each item quickly.
- 06
Plan-reading memos protect you from scope, you could not see by recording exactly what was and was not priced.
- 07
Estimates are delivered in a CSI-organized workbook, with each quantity linked to the plan sheet it came from.
Reviews
What contractors say after their first bid with us
What general contractors, subcontractors and developers say after bidding with our numbers.
“Squares, underlayment, flashing lengths, fastener counts, even the ridge vent. The waste factors were right for the roof pitch. Bid-ready out of the box.”
Greg Lindqvist
Estimator, Summit Roofing Co. · Kansas City, MO
“Having a design-development estimate before we finished CDs let us value-engineer the envelope while it still mattered. Clear, fast, and the estimators speak our language.”
Aisha Bello
Principal, Bello Architecture Studio · Atlanta, GA
“Cubic yards, rebar tonnage, formwork contact area and block counts by size. Exactly how I think about a job. We have won four of the last five bids they priced.”

FAQ
Blueprint Estimating FAQs
Straight answers on scope, turnaround, pricing and deliverables.
Can you estimate from low-quality scans or photos of plans?
Usually, yes. We check every sheet against a dimensioned wall, grid or door width, correct for distortion and measure from the verified scale. If a photo is too skewed or cropped to measure reliably, we tell you before starting and recommend the sheets to rescan.
What happens when drawings are missing details?
We price what is shown, carry a documented allowance for what is missing, and list each gap in an RFI log with the sheet and area affected. You can send the log to the architect or owner, and we update the estimate when answers arrive. Open questions stay visible until answered.
Do you read structural and MEP drawings too?
Yes. Plan reading covers architectural, structural, mechanical, electrical and plumbing sheets, and we cross-check them against one another. A beam clashing with a duct run or a panel missing from the electrical schedule gets flagged in the plan-reading memo. Findings are written in plain language for the design team.
How accurate is an estimate from incomplete plans?
Accuracy follows the information available. A complete modern set supports a detailed estimate within about 5% of awarded value. Hand sketches support a Class 4 range, and we label allowances clearly so you know which numbers are measured and which are placeholders awaiting design. We never present allowances as measured quantities.
Do you need the original paper blueprints?
No. A PDF or image file at the highest resolution you have is enough. For large-format sets, scan at 200 dpi or better and include the title block and scale bar on every sheet. We confirm readability before quoting the turnaround. Please send every sheet you hold, even unclear ones.
Can you review plans without producing an estimate?
Yes. A plan review and RFI report identifies scale problems, conflicts between disciplines, missing sheets and unclear scope. Many contractors order one before deciding whether to bid, using it to judge risk and to send questions to the design team early. The report usually reaches you within one working day.
