Construction estimating software: takeoff and bid tools compared

Estimating software splits into two jobs: takeoff (measuring quantities from drawings) and estimating (pricing them into a bid). Some tools do one, some both, and several are built for one trade. This guide sorts the main tools by what they do and who they suit, and ends with the step most estimating teams skip: feeding actual job cost back into the next bid.

Key takeaways
  • Takeoff measures; estimating prices — many teams need both.
  • Choose by trade: GC, electrical/mechanical, heavy civil and residential tools differ.
  • Estimate in the ERP's cost-code structure so it becomes the budget.
  • Feed actual unit costs from finished jobs back into the database.

The main tools

Bluebeam Revu

PDF markup & takeoff

PDF markup, measurement and document collaboration used across design and construction; widely used for takeoff and plan review.

ExampleAn estimator measures areas and counts on PDFs and marks up the set to send questions to the architect.
Best for
Almost everyone — the default PDF tool in many firms.
Check
Whether you need a dedicated estimating database on top of it.

On Center On-Screen Takeoff

Takeoff

Long-established desktop takeoff software, often paired with On Center’s Quick Bid for estimating.

ExampleA commercial sub measures a 200-sheet set with conditions and sends quantities to Quick Bid for pricing.
Best for
Commercial subcontractors and GCs with high takeoff volume.
Check
Desktop versus cloud needs for your team.

PlanSwift

Takeoff

Point-and-click takeoff with assemblies, popular with subcontractors.

ExampleA flooring contractor drags assemblies onto plans and gets material quantities with waste built in.
Best for
Trade contractors wanting quick takeoff with assemblies.
Check
How its output reaches your estimate or ERP.

STACK

Cloud takeoff & estimating

Cloud-based takeoff and estimating for subcontractors and GCs.

ExampleThree estimators work the same bid in the browser and share one takeoff.
Best for
Teams that want takeoff in the browser, shared across estimators.
Check
Assembly libraries for your trade.

ProEst (Autodesk)

Cloud estimating

Cloud estimating acquired by Autodesk, connecting estimates with Autodesk’s construction platform.

ExampleA GC turns an estimate into the job budget in its Autodesk project without retyping the cost codes.
Best for
GCs already on Autodesk Forma.
Check
Cost database set-up and how estimates become budgets.

Sage Estimating

Estimating

Estimating with cost databases and assemblies, designed to hand budgets to Sage accounting.

ExampleA contractor on Sage 300 CRE builds bids from its own cost database and hands the budget straight to accounting.
Best for
Contractors on Sage 300 CRE.
Check
The estimate-to-budget hand-off by cost code.

HCSS HeavyBid

Heavy civil estimating

Estimating built for heavy civil and infrastructure — crews, equipment and production rates.

ExampleA highway contractor prices earthwork from crew, equipment and production rates for a DOT bid.
Best for
Heavy civil, highway and utility contractors.
Check
Equipment rate set-up and bid-day workflow.

Trimble Accubid

Electrical estimating

Estimating for electrical contractors with labor units and trade databases.

ExampleAn electrical contractor prices a 400-device job from labor units and adjusts for the site conditions.
Best for
Electrical contractors.
Check
Labor unit libraries against your own productivity.

AI takeoff tools (Togal.AI, Beam AI, Kreo) are covered in the AI estimating guide.

The hand-off most teams get wrong

An estimate is only useful after award if it becomes the budget in the same cost-code structure. When the estimate is by assembly and the budget is by cost code, nobody can compare them, and the lesson from every finished job is lost. Set the estimate’s cost codes to match the ERP’s, and transfer the budget electronically rather than retyping it.

Estimating software is only as good as its handoff. If the estimate’s cost codes are the budget’s cost codes, every later cost can be measured against the line that assumed it.

Feeding actual cost back into the next bid

The best estimating data a contractor owns is its own finished jobs: what each cost code actually cost per unit, by crew and project type. Pull actual unit costs from job cost after close-out, compare them with the estimate, and update the database — see the cost codes guide. Constructelligence does this comparison across every finished job automatically.

What this template captures

Estimated and actual quantity and unit cost for every cost code on a finished job, the variance calculated, and whether the cost database should change.

10 columns: 8 you fill in, 1 picked from drop-down lists, so every row uses the same values and 1 calculated by formula and filled down 200 rows, so nothing is worked out by hand. In the Excel version, 4 columns reject entries of the wrong type (a date column only takes dates, an amount column only numbers), the header row stays frozen with filters on it, and the workbook opens on an Instructions sheet that lists every column below.

Every column, and how it is captured

Frequently asked questions

What is the best construction estimating software?

It depends on trade: Bluebeam Revu and On-Screen Takeoff are widely used for takeoff; STACK and ProEst for cloud estimating; Sage Estimating for Sage 300 CRE users; HCSS HeavyBid for heavy civil; Trimble Accubid for electrical. AI takeoff tools such as Togal.AI add automated measurement.

What is the difference between takeoff and estimating software?

Takeoff software measures quantities — counts, lengths, areas — from drawings. Estimating software prices those quantities with labor, material, equipment and markup into a bid. Some products do both.

How do I make estimates more accurate?

Compare every finished job's actual cost with its estimate by cost code, update unit costs and productivity rates from those actuals, and keep the estimate in the same cost-code structure as the budget so the comparison is possible.

Is Bluebeam an estimating tool?

Bluebeam Revu is a PDF markup and collaboration tool with strong measurement features, so it is widely used for takeoff. Most estimating teams pair it with a separate estimating database or spreadsheet for pricing.
