The three-stage estimating flow (Takeoff → Scope → Estimate)
BuiltUp splits estimating into three linked stages the way professional estimators actually work. Here's what each stage is for, how they flow into each other, and why running them separately gets you tighter quotes and fewer disputes.
Most builders run takeoff, scope and estimate as one tangled spreadsheet — which is why most quotes miss items, underprice labour, and leak margin. The professional move is to separate them cleanly, then link them. BuiltUp's Scope section is built around this pattern: three inner tabs (Takeoff · Scope · Estimate) that feed into each other in sequence. This guide explains the mental model so the rest of the estimating track makes sense.
Stage 1 — Takeoff (measure)
The Takeoff tab is where you answer the question *"how much of each thing?"*. You upload your plans, BuiltUp extracts every measurement, count and area it can find, and tags each row with a confidence score (HIGH / MEDIUM / LOW) based on whether the dimension was explicitly drawn or inferred from context.
What a good takeoff looks like:
- An area schedule listing every named room with its square metres
- A trade-package breakdown — Demolition, Partitions, Doors, Floor Finishes, Ceiling Finishes, Wall Finishes, Joinery, Kitchen Equipment, HVAC, Plumbing, Electrical, Fire Safety, Frontage
- 60–150 measurement rows on a commercial fit-out, 30–60 on a residential job
- A list of open questions (items that need MEP design, datasheets, or site verification before pricing)
What a takeoff is NOT: prices. You won't see a pound sign anywhere in the Takeoff tab. That's deliberate — measurement and pricing are separate jobs and mixing them is where people miss items. Pricing happens in Stage 3.

Stage 2 — Scope of Works (define)
The Scope tab is the written description of the job — what's included, how it should be done, what's excluded. It's the document you'd hand to a subcontractor asking them to quote.
BuiltUp generates it automatically from your Takeoff + Estimate. The output is a professional trade-by-trade document with 15-17 sections: Preliminaries, Demolition, Partitions, Finishes, Joinery, MEP, Compliance, and — critically — Exclusions. You can edit any section inline, toggle sections in or out of the final quote, and the exclusions list has its own editor so nothing creeps in later and catches you out.
The two reasons this stage matters:
1. Clarity for the builder. "Install flooring" is a fight waiting to happen. "Supply and install commercial-grade vinyl flooring to all customer and circulation areas, including substrate preparation, adhesive, edge trims, and making good to door thresholds" is a quote. 2. Protection via exclusions. Listing what's NOT included is how you avoid free work. If you don't document that planning permission isn't yours to deal with, you'll end up doing it for free.
Stage 3 — Estimate (price)
The Estimate tab is where the money lives. This is the BOQ (bill of quantities) — rooms, components, materials, labour, unit prices, waste factors, markup, and the running totals for Good / Better / Best material tiers.
You land here after pushing rows from Takeoff, after AI Scope Architect generates the initial breakdown, or by building manually room-by-room. Everything priced here feeds the quote PDF.
The three tiers are generated automatically from your material variants, so a single scope becomes three prices you can present to the client at once. This is the single biggest lever for winning middle-tier work (the anchoring effect is real).
Live supplier pricing (Pro+) watches your material prices in the background and warns you if a cost has moved on an active quote before the client locks it in.
How the stages link
The three stages pass data forward:
- Takeoff → Estimate — select measurement rows and click "Push to Estimate". BuiltUp creates the Rooms and Components automatically, matches units, and flags items that need pricing. You never retype a number.
- Takeoff + Estimate → Scope of Works — the AI reads both when generating your written SoW so the sections reference real quantities and real rooms instead of generic language.
- Estimate → Quote PDF — the line items feed the BOQ page of your tender pack.
- Scope of Works → Quote PDF — the written sections feed Section 02 of the quote, with your exclusions block included automatically.
The output is a professional three-part tender pack: drawings, scope narrative, priced BOQ. The same thing quantity surveyors charge £800 a day to produce, in one platform, in an hour.
The order you should actually work in
Pragmatic sequence on a real job:
1. Start on Takeoff. Run the AI analysis on your plans. Review the measurements, especially the LOW-confidence rows. Push the HIGH ones to the Estimate. 2. Jump to Estimate. The rows are there waiting. Apply prices from your rate book, tune labour, check the tier totals. This is also where you'd run AI Scope Architect if you prefer the "full scope in one shot" approach. 3. Generate Scope of Works. Hit "Generate with AI" on the Scope tab. The sections come back already referencing your takeoff trade packages and your estimate rooms. Review, edit the exclusions, approve. 4. Send the quote. The PDF pulls from all three. Your client sees a cover page, a written scope, a BOQ, and your terms — laid out like a proper tender pack.
Total time on a residential bathroom job: 15–25 minutes. On a commercial fit-out: 45–90 minutes. Both are 5-10× faster than building the same tender pack by hand.
Once you understand the three stages, every other guide in this track slots in. The AI Scope Generation guide walks through Stage 3 in detail. The Takeoff Analyzer guide walks through Stage 1. The Scope of Works guide walks through Stage 2. The Material Tiers guide covers the pricing lever inside Stage 3. The Building Scope Manually guide is for when you want full control of Stage 3 without AI help.

Generating a scope with AI
Upload a set of plans, write a one-line brief, and BuiltUp's AI Scope Architect builds a full priced scope — rooms, materials, labour, waste factors. Here's how to get the most out of it.
Building a scope manually
When you'd rather build a scope from scratch — or edit what the AI gave you — here's how the scope editor actually works: rooms, components, quantities, waste factors, and the material search.
Using the AI Takeoff Analyzer
Upload plans and BuiltUp extracts measurements, counts and areas — with a confidence score on every line so you know what to trust. Then push the ones you're happy with straight into your scope.
