How AI construction estimating actually works, who uses it, and the deep trade secrets that separate a winning bid from one that loses money. All in plain English.
No jargon. Here is the whole thing in three sentences, then three steps.
When a contractor bids a job, they have to count everything on a blueprint — every light, every pipe, every sheet of drywall, every square foot of paint. That counting is called a takeoff. It is slow, boring, and expensive. PILRS reads the blueprint for you and does the counting in minutes. You review the numbers, adjust the prices, and send the bid. That is it.
Drag and drop the PDF drawings — architectural, structural, MEP, whatever the architect sent you. Any size set. Any trade.
Like dropping a recipe into a smart kitchen. The ingredients list writes itself.
PILRS reads each page, finds every symbol, measures every line, and adds it all up. Walls in linear feet, floors in square feet, outlets and pipes as counts. All sorted by room and drawing number.
Like an estimator who never gets tired, never misses a page, and works at computer speed.
Open the result, check the quantities, drop in your labor rates and material prices, and export the bid as CSV or PDF. From plan set to priced proposal in under an hour.
Like having a first draft ready before you pour your first cup of coffee.
Not for desk-bound software buyers. For the estimators, foremen, and owners who actually have to bid.
Bid more jobs without hiring more estimators. Get consistent numbers across every trade, every project, every time.
Drywall, electrical, plumbing, HVAC, concrete, steel, roofing, and more. Bid faster, bid smarter, stop losing margin to guesswork.
Take on more clients without drowning. Spend your time on strategy and relationships, not counting receptacles at 2 a.m.
Real answers, written by estimators, in language a first-year apprentice could follow.
PILRS is AI construction estimating software. You upload a PDF plan set, and PILRS turns it into a priced bid in minutes. It does the takeoff (the counting), lines up your quantities with the CSI MasterFormat system most GCs use, and handles labor burden plus assembly pricing so the number you send out is a number you can stand behind.
Three things happen behind the scenes. First, PILRS reads your PDF drawings the same way a human estimator does — it looks at each page and identifies every symbol, line, and dimension. Second, it measures those objects: lengths in linear feet, areas in square feet, and counts for things like outlets or diffusers. Third, it organizes the results by room, drawing, and CSI division so you can sanity-check everything in one table. You review, adjust anything the AI got wrong, then export to CSV or price it directly.
On a typical commercial plan set, PILRS catches 90–98% of the scope automatically. That means an estimator spends 30–60 minutes reviewing and correcting instead of 4–8 hours doing the whole takeoff from scratch. For repetitive trades like drywall, electrical rough-in, or plumbing fixtures, accuracy at the symbol level is often above 95%. Anywhere the drawings are unclear (scanned PDFs, hand markups, partial revisions), PILRS flags it for your review instead of guessing silently.
Sixteen trades today: drywall, electrical, plumbing, HVAC, concrete, structural steel, masonry, roofing, painting, carpentry, civil and sitework, glazing, fire protection, insulation, flooring, and landscaping. Each trade has its own templates so the output matches how that trade actually bids — linear feet of track and stud for drywall, tonnage for steel, cubic yards for concrete, fixture count for plumbing, and so on.
Yes. PILRS is a modern, AI-native alternative to all of them. Bluebeam and PlanSwift are manual tools — you still click every object. STACK is cloud-based but still mostly click-and-measure. Togal and iBeam are AI-first like PILRS, but PILRS supports more trades, runs in the browser with zero plugins, and gives you a CSI-aligned output instead of a raw count. If you already use Bluebeam for markup, PILRS plays nicely alongside it.
For a 20–50 page commercial plan set, the first-pass AI takeoff runs in under 10 minutes. Estimator review and adjustments usually add 30–60 minutes. So end-to-end: about an hour, versus 4–8 hours for a full manual takeoff. On larger projects (200+ pages), the AI pass takes longer but still finishes before you'd be done highlighting page one by hand.
Yes to the trial, no to the credit card. You get 14 days of full access — every trade, unlimited takeoffs, full export. No credit card required to start. If it works for your bids, pick a plan. If not, no charge and no awkward cancel call.
Any PDF. Vector PDFs (the kind exported directly from Revit, AutoCAD, or Bluebeam) work best because PILRS can read the linework directly. Scanned or raster PDFs (the kind where someone photographed a printed plan) also work — PILRS runs OCR first to pull out text and symbols, then does the takeoff. If the scan is truly low quality, you'll get a warning before the takeoff runs so you're not surprised by the output.
Yes. The product is built so a working estimator — or even a foreman stepping into their first bid — can upload a plan and read the output on day one. There's no training certification, no installer, no plugins. If you can read a blueprint and open a spreadsheet, you can use PILRS. Our onboarding videos are under five minutes each and most users ship their first real bid in the first week.
No, and that's the point. PILRS replaces the counting, not the thinking. Your estimator still makes the judgment calls — which trades to self-perform, how aggressive to be on labor, where to add contingency, which subs to trust on a given scope. What PILRS removes is the 4–8 hours of highlighting PDFs with a mouse. Your estimator walks into the bid review with the quantities already done, which means more time on strategy and more bids out the door.
Your plan sets stay private to your account. They aren't used to train public AI models, they aren't shared across accounts, and you can delete a project at any time. We encrypt files in transit and at rest. For teams bidding sensitive work (federal, healthcare, data centers), we offer single-sign-on, audit logs, and dedicated infrastructure on request.
Simple pay-per-takeoff pricing: $50 to $100 per takeoff depending on the size of the plan set. A small tenant improvement set (under 25 pages) runs $50. A mid-size commercial set (25–100 pages) runs around $75. A large multi-building or multi-floor set (100+ pages) runs up to $100. No subscriptions, no per-seat fees, no minimums. You pay only when you run a takeoff — so a sub who bids four jobs a month pays for four takeoffs, not a full year of software. Most users pay for the whole month's usage out of the first bid they win.
The stuff nobody writes down. Short, sharp, and straight from the bid room.
Because field waste is real and measured scrap is not the same as ordered material. Drywall sheets snap on the truck, paint rolls onto drop cloths, and the last stud in every wall is a cut. The honest number is 7% for drywall, 10% for paint on textured walls, 15% on rough CMU. Push back when a GC wants you under those — they're asking you to eat change orders.
All three are conservative by design — they're defensive numbers. NECA Column 2 is average; Column 3 is tight, Column 1 is difficult. Most winning electrical bids price Column 2 then shave 8–15% based on crew and repetition. MCAA has similar tiers. If you bid straight manual labor units, you lose. The secret is knowing which tier your crew actually hits.
A phantom quantity is a line item that exists on the drawings but not in the spec book (or vice versa). Classic examples: fire-rated sealant at top of wall, blocking behind TV mounts, sleeves through rated assemblies. It's in the scope but not priced. On a $2M job, 3–5 phantom quantities can eat your entire profit. Always cross-check spec section against plan notes before you send the number.
Read the spec section first, then open the drawings. If the spec calls for Type X gyp and the drawings show standard ½″, the spec wins per the general conditions — but the takeoff needs to reflect Type X pricing. Three places mismatches hide: door hardware schedules, roofing assembly specs, and fire-rated partitions. Those three alone account for most scope disputes.
Because they're almost never consistent between the drawings, the spec, and the invitation to bid. If the drawing says “grounding by electrical” and the spec says “grounding by equipment vendor,” somebody is going to install it for free. Rule: list every “by others” note in your bid qualifications so the GC has to assign it in writing before award.
Hoisting, scaffolding, and lift rentals. On anything over 14 feet, lift rental alone can be $1,200–$2,500 per week. Estimators nail the takeoff but forget the machine that gets a worker to the ceiling. Number two miss: dust protection and containment on occupied buildings — that's often 1–2% of the job by itself.
A cloud is a flag, not a scope statement. Read the revision narrative in the title block. If the note says “clarification,” no cost impact. If it says “added” or “revised per RFI,” assume it is a change in scope and price it as an add. Never swallow a clouded revision silently. Log every one in your bid notes with a yes/no cost call.
Hard bid. Always. In a hard bid, the drawings are fixed and you take the full risk of errors, coordination, and scope gaps. In design-assist, the owner pays you to identify those gaps before construction. Hard bids need 3–7% contingency on top of normal markup because you'll eat the mistakes. New estimators confuse the two and lose money on hard bids every time.
Because they show up in Division 7 specs but get drawn on mechanical, electrical, and plumbing sheets. Each trade assumes another one is pricing it. On a 4-story med-office, fire-stop can be $15,000–$40,000 of scope — and if no one priced it, the GC issues a field directive and splits the cost. Always carry fire-stop in your MEP bid with a qualification note.
On $5M of work with a 4% net margin, 2% error wipes out half your profit. That's why experienced estimators spend an hour sanity-checking totals against historical per-square-foot numbers. If your drywall bid comes in at $4.10/sf on a job that usually runs $5.50/sf, something's missing — don't submit until you find it.
Because material prices are published and stable; labor is where every bid is won or lost. A 10% material error on a drywall job moves the total 3%. A 10% labor error moves it 7–8% because labor is usually the bigger bucket after burden. Lock your crew productivity rate first, then price material. New estimators do it backwards and underbid themselves.
Waste is the material that becomes scrap on your own site — cuts, drops, offcuts. Shrinkage is theft, damage in transit, and miscounts at delivery. Most bids carry waste but ignore shrinkage. On jobs over 6 months, add 1–2% shrinkage on top of your waste factor, especially for copper, tools, and high-value fixtures. Your PM will thank you when the job closes.
Three red flags. One: specs reference products you can’t get a distributor quote on within 48 hours. Two: the bid list has 8+ subs of your size — the owner is shopping, not buying. Three: the GC won’t share addenda or RFI answers. Chasing any of those three is how shops go broke. No-bid and focus on the next job.
Any bid more than 10% below the second lowest gets flagged. Sharp owners and GCs know low bids become change order factories — and they’ll either reject you upfront or ride you on every clarification during construction. Winning a job you underpriced is worse than losing it. You pay for the mistake twice: once in margin, once in reputation.
