Quanto for Revit: How to Turn BIM Models Into Priced BOQs

A Revit model contains valuable quantity information, but producing a priced Bill of Quantities still requires significant commercial work. Elements must be identified, grouped under the correct measurement rules, matched with suitable rates, checked, and formatted for issue.

Quanto for Revit connects those steps in one workflow. It extracts takeoff information from a Revit model, identifies building elements, predicts line-item rates from the firm's historical pricing, and creates a fully formatted priced BOQ for expert review.

The objective isn't to remove the quantity surveyor. It is to reduce repetitive model measurement and manual pricing so the QS can spend more time checking assumptions, identifying risk, and advising the client.

Key takeaways

• Quanto extracts takeoff information natively from Revit models.
• It groups model elements using NRM2 or other agreed measurement rules.
• Its AI rate engine uses the firm's historical pricing data.
• The result is a priced BOQ that remains subject to expert review.
• Concolabs currently lists the Revit package at USD $1,000 per month.

What is Quanto for Revit?

Quanto for Revit is an AI-assisted quantity takeoff and pricing workflow for quantity-surveying practices. It reads information from the Revit model and carries that information through element identification, measurement, rate prediction, and BOQ formatting.

Many takeoff tools stop after measuring model elements. Quanto extends the workflow by predicting and applying rates to individual bill items. According to the current product page, the output can be exported to Excel, CSV, or specialist BOQ software when required.

The product is currently positioned for QS consultancies in the Middle East and Sri Lanka. Concolabs lists it as a scaling product rather than a generic one-size-fits-all estimating application.

Why does BIM-based BOQ preparation still take so long?

BIM doesn't automatically create a commercially complete bill. Design models are normally organized for design development and coordination. Their structure may not match the work sections, descriptions, classifications, and measurement rules needed by a quantity surveyor.

An estimator may still need to inspect model coverage, identify duplicates, interpret object types, separate measured and non-measured items, and confirm the correct units. Rates must then be found and adjusted for location, date, specification, quantity, and procurement conditions.

Manual transfer introduces another problem. When quantities move through spreadsheets and disconnected rate libraries, it becomes harder to trace an issued figure back to the model element and pricing basis.

Quanto addresses this administrative bottleneck. It doesn't remove the need to check the model. Instead, it gives the QS a structured first result and directs attention toward exceptions.

How does Quanto for Revit work?

The Quanto for Revit workflow follows four main stages.

1. Revit integration

The native plugin extracts takeoff files and raw information from the Revit model. This avoids rebuilding the model's quantity information manually in a separate spreadsheet.

Before extraction, the project team should identify the controlled model version. Work-in-progress design changes shouldn't become part of an issued cost document without an agreed review process.

2. Element identification

Quanto groups and identifies model elements using the required measurement logic. This stage connects design objects with commercial work items.

Consistent object names, classifications, types, phases, and parameters improve the result. Low-quality model information should be corrected or handled through a documented exception process.

3. AI rate prediction

The rate engine predicts pricing for each line item from the firm's historical data. This reduces repeated searches through old BOQs and rate libraries.

Historical information needs context. A useful record should identify the rate date, location, project type, unit, specification, quantity range, procurement conditions, and whether the rate was tendered, accepted, or adjusted.

4. Priced BOQ output

Quanto generates a formatted priced Bill of Quantities for professional review. The QS checks quantities, descriptions, rates, scope, assumptions, exclusions, risk allowances, and totals before approval.

The completed BOQ can also become a measurement baseline for construction-stage valuation through MeasureonAir. At an earlier stage, it can connect with the commercial framework established through the Concolabs Cost Plan Calculator.

Which measurement standards and outputs are supported?

Concolabs states that Quanto supports NRM2 and other measurement standards. Elements can be grouped and measured according to the firm's rules rather than being forced into a single universal structure.

The product page also lists four source formats across the wider Quanto engine: Revit, Autodesk Construction Cloud, CostX, and 2D PDF or DXF drawings. The Revit edition uses the same rate-prediction approach while providing a native model workflow.

Final BOQ information can be exported to Excel or CSV. Concolabs also describes export to specialist BOQ software where the deployment requires it.

How does AI rate prediction use historical pricing?

Quanto is trained on the firm's historical rate information before deployment. As more relevant project data is added, the available pricing knowledge can become more representative of the firm's work.

That doesn't mean every historical rate should be treated equally. A price from a different country, market cycle, specification, or contract type may be unsuitable without adjustment. Old descriptions may also hide important scope differences.

A responsible rate workflow should therefore include:

• Consistent item descriptions and units
• Dates and project locations
• Specification and quality information
• Accepted versus tendered rate status
• Confidence thresholds for automated matches
• A review route for unusual or low-confidence items
• A record of every adjustment and approval

The strongest use of prediction is triage. Common items can move quickly, while experienced estimators focus on exceptions and commercial risk.

How does Quanto compare with manual BOQ preparation?

Manual BOQ preparation gives the estimator direct control, but it also requires repeated measurement, rate lookup, copying, and formatting. That creates an omission risk and consumes time that could be used for advice and review.

Standard takeoff software can reduce the measurement workload. However, pricing often remains a separate manual stage. Quanto combines element identification with rate prediction and priced BOQ production.

Concolabs describes a move from a weeks-long process to a result produced in hours and ready for expert review. The exact saving will depend on model quality, project complexity, measurement rules, historical data, and the firm's approval workflow. A pilot should test those factors before the business case is finalized.

Does Quanto for Revit replace estimators?

No. Estimators and quantity surveyors remain responsible for the commercial output. Quanto automates repeatable tasks; it cannot accept professional responsibility for design completeness, measurement interpretation, market judgment, procurement strategy, or project risk.

The QS should continue to review:

• Model completeness and revision status
• Measurement rules and classification
• Scope gaps and design assumptions
• Provisional and abnormal items
• Rate dates, locations, and specifications
• Preliminaries, risk, and contingency
• Low-confidence elements and mappings
• The final BOQ before issue

This review-first approach combines machine speed with professional accountability.

What does Quanto for Revit cost?

As of August 2026, the Quanto for Revit product page lists a monthly subscription of USD $1,000. The published package includes the native Revit plugin, rate-prediction module, and customizations.

Concolabs also lists a custom enterprise plan for multi-office deployment and training on complex proprietary historical rates. Buyers should confirm current pricing, onboarding scope, supported customizations, data preparation, training, and regional availability before purchasing.

How should a QS firm pilot Quanto for Revit?

Start with a completed project that has a controlled Revit model and an approved BOQ. This creates a reliable comparison baseline.

Run the automated workflow without changing the approved benchmark. Compare extracted quantities, element grouping, descriptions, predicted rates, exceptions, and total review time. Record where differences came from rather than measuring only the final total.

A useful pilot should assess:

1. Model-element identification accuracy
2. Quantity agreement by work section
3. Rate-prediction relevance
4. Number of low-confidence items
5. Time required for professional review
6. Export and template compatibility
7. Handling of a controlled design revision
8. Traceability from BOQ item to model and rate source

The pilot should end with clear acceptance thresholds and ownership for unresolved exceptions.

Frequently Asked Questions

Can Quanto's AI rate prediction adapt to our firm's historical pricing?

Yes. Concolabs states that Quanto is trained on the firm's historical rate data before deployment. Adding well-structured project data can make future suggestions more relevant. Firms should still maintain data-quality rules and require professional approval for predicted rates.

What measurement standards does Quanto for Revit support?

The product page identifies NRM2 and other measurement standards. The workflow can group and measure model elements according to the firm's agreed rules. Confirm any regional, client-specific, or bespoke standard during product configuration.

Does Quanto for Revit replace quantity surveyors or estimators?

No. Quanto reduces repetitive model measurement, item grouping, and rate application. Quantity surveyors remain responsible for model checks, measurement interpretation, scope, pricing context, risk, professional advice, and approval of the final BOQ.

Can the final BOQ be exported to Excel?

Yes. Concolabs lists Excel and CSV exports, along with the option to send information into specialist BOQ software. Teams should confirm the exact mapping and formatting required by their current systems during a pilot.

How does Quanto for Revit differ from Quanto for ACC?

Quanto for Revit extracts information natively from a Revit model through its plugin. Quanto for ACC is intended for a connected Autodesk Construction Cloud workflow and can reprice the BOQ as cloud-hosted design proposals change. The right option depends on the firm's controlled model environment.

Can Quanto identify items that need additional review?

Yes. Concolabs states that low-confidence elements can be flagged for review. This helps estimators focus on uncertain classifications or mappings rather than treating every automated result as equally reliable.
