MeasureonAir: Digital Site Measurement to Payment Application

Interim valuation often begins with printed drawings and handwritten measurements. Site engineers mark completed work on paper, return to the office, copy quantities into spreadsheets, compare them with the BOQ, and prepare the payment application manually.

MeasureonAir turns those disconnected stages into one digital workflow. Users record lengths, areas, counts, depths, heights, coordinates, and photo evidence against the drawing on site. The application checks the quantities against the BOQ and contract rules before compiling an interim payment application.

Measurement happens once, where the work can be observed. Authorized quantity surveyors, engineers, and contract administrators still review, agree, and certify the commercial result.

Key takeaways

• Record site quantities directly against controlled digital drawings.
• Work through the web or mobile app with or without connectivity.
• Attach location and photographic evidence to measured work.
• Apply BOQ tolerances, defect rules, holdbacks, and contract checks.
• Concolabs currently lists MeasureonAir at USD $200 per company per month.

What is MeasureonAir?

MeasureonAir is a digital construction measurement, valuation, and payment-application product for quantity surveyors and site engineers. It connects the BOQ baseline with work measured on site and the documents used to administer payment.

The product is designed for construction-stage use in the Middle East and Sri Lanka. Concolabs lists an implementation period of approximately one week when a baseline BOQ is available.

MeasureonAir can operate as a web or mobile application. Its offline workflow synchronizes the BOQ and drawing information to the site device, allowing the user to record progress where continuous connectivity isn't available.

Why are manual interim valuations slow?

Traditional valuation separates site observation from commercial preparation. Measurements are marked on printed plans or written in notebooks, then interpreted again in the office. Each transfer introduces another opportunity for omission, transcription error, or version confusion.

Traceability is also weak. A value in the payment application may be difficult to connect with the exact drawing area, measurement, photograph, date, and reviewer that supported it.

Revisions make the problem harder. If the drawing changes, teams must identify which measurements belong to the previous design and which require rework, adjustment, or variation treatment.

MeasureonAir keeps the measurement connected to its digital source and commercial destination. This reduces duplicate entry while preserving a reviewable history.

How does MeasureonAir work?

The MeasureonAir workflow follows five main stages from site measurement to payment application.

1. Open MeasureonAir on site

The user opens the web or mobile application on the project device. Concolabs states that the product works online or offline.

Before field use, the project team imports the controlled baseline BOQ and drawing set. Users, roles, locations, measurement rules, tolerance limits, and approval stages should be configured during setup.

2. Select the drawing section

The site engineer or quantity surveyor selects the relevant part of the digital drawing. Concolabs identifies walls, slabs, openings, and finishes as example building elements.

Working from a controlled revision is essential. The selected drawing should show its number, revision, issue status, and effective date so users don't measure against superseded information.

3. Record the site measurement

The user records length, area, count, depth or height directly on the drawing. Photo and coordinate evidence can be attached to support the observation.

Each entry should identify the BOQ item, location, measurement date, responsible user, unit, quantity, method, and comments. This creates a traceable source record for later review.

4. Calculate and check the quantity

MeasureonAir compares recorded progress with the BOQ baseline and configured rules. The product page describes tolerance checks, defects, and holdbacks within this stage.

Concolabs gives an example tolerance of plus or minus five percent, but each contract and project may require different limits. Teams should configure the actual rules rather than adopting an example automatically.

5. Generate the payment application

The system compiles the measured and reviewed information into an interim certificate, payment summary, or payment application ready for administration.

The generated document remains subject to the project's measurement, agreement, review, and certification process. Software can prepare the calculation; only authorized participants can approve it.

What types of site measurement can be recorded?

MeasureonAir supports common construction quantity types, including:

• Linear measurements for walls, edges, services, and finishes
• Areas for slabs, formwork, finishes, and surfaces
• Counts for fixtures, openings, components, and installed units
• Depth and height measurements
• Drawing-based coordinates and locations
• Photographic evidence
• Notes about defects, rework, or incomplete work

The measurement method should follow the BOQ and contract rules. Where an item uses a composite quantity, users may need to record several dimensions or supporting observations.

The strongest implementation standardizes units, rounding, decimal precision, descriptions, location codes, and evidence requirements before site teams begin.

How does MeasureonAir use the BOQ baseline?

The application imports a baseline quantity structure from Concolabs Revit-to-BOQ or 2D Drawing-to-BOQ workflows. It can then synchronize that commercial baseline with the site device.

Every site measurement should map to the correct BOQ item. This allows the system to compare previous progress, current progress, cumulative quantity, certified quantity, paid amount, and remaining balance.

The baseline should be version-controlled. If the BOQ changes because of a variation or design revision, the project needs a clear process for updating the structure without losing previous certificates or measurement history.

A controlled baseline prevents field measurements from becoming disconnected quantities with no commercial context.

How are tolerances, defects, and holdbacks handled?

MeasureonAir can apply configured tolerance boundaries and contract holdback rules when a measurement is locked. Concolabs also describes defect-related checks.

These controls can flag quantities that exceed expected limits or should not be certified in full. Examples include incomplete work, known defects, retention, or items outside the agreed BOQ quantity.

The system shouldn't decide contractual entitlement without review. A flagged quantity may reflect a valid variation, measurement error, drawing discrepancy, or change in scope.

Every exception should have an owner, reason, supporting record, resolution status, and approval. Automated checks are most valuable when they make unusual quantities visible before payment.

What happens when site measurements don't match the drawing?

Concolabs states that measurements are compared with the baseline drawing and that differences outside configured tolerances are flagged for manager review.

The reviewer should determine whether the discrepancy resulted from:

• Incorrect field measurement
• Drawing scale or revision error
• Construction outside the approved design
• Approved variation or instruction
• Design development
• Rework or defective work
• Unrecorded opening or change
• BOQ quantity or mapping error

The original measurement and evidence should remain in the history even after correction. This preserves an audit trail and helps explain why the certified quantity changed.

How does MeasureonAir manage drawing and measurement history?

MeasureonAir tracks drawing takeoff edits and quantity adjustments. Its measurement history can show baseline progress and certification records across successive periods.

This supports recurring interim valuations. A reviewer can distinguish current-period work from previously measured, certified, or paid quantities.

Version control should capture drawing revision, measurement edit, user, timestamp, reason, and approval. Deleted or superseded records should remain traceable according to the organization's retention policy.

The objective is not only a correct current total. The project should be able to reconstruct how that total developed over time.

Can MeasureonAir work without internet connectivity?

Yes. The product page states that MeasureonAir works offline and synchronizes the baseline information to the site engineer's tablet.

Offline use is important in basements, remote projects, large sites, and partially completed buildings where network coverage may be unreliable.

The implementation should test device storage, synchronization status, conflicting edits, lost devices, authentication, and the valuation cut-off process. Users need a clear indication of which records remain local and which have synchronized successfully.

Offline capability should preserve productivity without weakening data control.

How does MeasureonAir generate payment applications?

After measurements are checked, the application compiles invoice summaries, interim valuations, and payment applications in standard contract formats. Concolabs also describes interim-certificate and payment-summary outputs.

A complete valuation may include:

• Original BOQ amount
• Previous certified value
• Current measured and certified quantity
• Cumulative value
• Variations and approved adjustments
• Defects or holdbacks
• Retention and other deductions
• Amount previously paid
• Current amount due
• Supporting drawing and photo references

Exact content depends on the contract and administrator's requirements. The generated output should be tested against an approved sample before live submission.

Does MeasureonAir automatically certify payment?

MeasureonAir automates quantity calculations, rule checks, and document compilation. Authorized professionals still make the certification decision.

The contractor may prepare a payment application. A quantity surveyor or engineer may review measurements. The contract administrator may certify an amount. Those roles and responsibilities depend on the contract.

The system should therefore maintain separate statuses for recorded, reviewed, agreed, submitted, certified, rejected, and paid quantities.

Automation supports the process. It doesn't transfer contractual authority to the application.

Which downstream systems can receive MeasureonAir data?

Concolabs states that MeasureonAir can export into ERPs and identifies SAP and Oracle as examples. It can also pass information to BuilderBot.ai for automated contract review.

Integration should use controlled project codes, BOQ items, currencies, suppliers, certificate numbers, and approval statuses. Organizations must decide which information is informational and which can create a financial posting.

Enterprise connections and custom workflows are offered through a custom plan. Buyers should confirm field mapping, authentication, permissions, audit logs, error handling, and reconciliation requirements during implementation.

How does MeasureonAir compare with manual valuation?

Concolabs compares a manual interim valuation taking two to three days with a MeasureonAir workflow completed in one to two hours. The digital process connects site measurement, drawing verification, quantity checks, and payment-document preparation.

Traditional tools may annotate drawings but stop before BOQ export, contract-rule enforcement, or payment-application compilation. MeasureonAir is designed as a continuous commercial workflow.

Actual time savings depend on project size, measurement complexity, baseline quality, user adoption, review requirements, and integrations. Firms should validate the comparison through a representative pilot.

What does MeasureonAir cost?

As of August 2026, the MeasureonAir product page lists USD $200 per month per company.

The flat-rate company license covers unlimited active projects and users. Concolabs identifies a one-week implementation period where a baseline BOQ is available.

A custom enterprise plan is available for tailored ERP connections and workflow setup. Buyers should confirm current pricing, baseline preparation, storage, devices, offline use, output templates, integrations, training, support, taxes, and regional availability before purchasing.

How should a contractor or consultancy pilot MeasureonAir?

Choose one live project and a defined trade or valuation section. Import the controlled BOQ and drawings, then configure the actual contract rules and certificate format.

Run digital measurement alongside the approved existing process for one valuation cycle. Compare item-level quantities, evidence, review time, exceptions, and certificate output.

A useful pilot should measure:

1. BOQ and drawing setup accuracy
2. Site measurement usability
3. Offline capture and synchronization
4. Quantity calculation accuracy
5. Drawing-location and photo traceability
6. Tolerance and holdback checks
7. Handling of discrepancies and variations
8. Time required for review and compilation
9. Payment-application format accuracy
10. Audit history and version control

Define acceptance thresholds before the pilot. A correct certificate total can hide item-level errors, so detailed reconciliation is essential.

Frequently Asked Questions

What is MeasureonAir?

MeasureonAir is a Concolabs digital site-measurement and valuation product. It records quantities against digital drawings, checks them against the BOQ and contract rules, and compiles interim payment applications and certificates.

How does it handle site measurements that don't match the drawing?

Measurements are compared with the baseline drawing. Differences outside configured tolerances are flagged for manager review. The reviewer determines whether the issue is measurement error, design change, variation, rework, or another cause.

What if site conditions change or work requires rework?

Record the changed condition, affected location, measurement, drawing revision, photograph, instruction, and status. Reworked or defective quantities can be separated or held back according to configured project rules and professional review.

Can measurements from previous periods or projects be used?

Previous certification periods remain available through the measurement history. A different project may provide useful reference methods, but its quantities shouldn't be transferred into the current valuation without project-specific verification.

How does MeasureonAir handle variations or contract changes?

Variations should be identified separately, connected with the relevant instruction and drawing revision, and mapped to an approved commercial item. The system can preserve the measurement and audit history while authorized reviewers determine entitlement and value.

What formats can payment applications use?

Concolabs describes interim certificates, payment summaries, invoice summaries, and standard contract-format payment applications. Exact Excel, PDF, ERP, or custom outputs should be confirmed during project configuration.
