Desktop Area Analysis (DAA) for Area Certainty Before You Build

At GeospatialWorx, our Desktop Area Analysis (DAA) service provides fast, reliable lettable-area calculations over your existing development documentation—no site visit required. Ideal for early leasing, design, and feasibility, our DAA gives you audit-friendly numbers aligned to PCA or IPMS so you can make decisions and set contracts with confidence.

What Is Desktop Area Analysis?

A Desktop Area Analysis is an off-site method of determining lettable or usable areas directly from architectural drawings, CAD files, or Revit models. Each analysis is carried out in accordance with the Property Council of Australia (PCA) Method of Measurement or other relevant frameworks such as IPMS.

This service is ideal for developers, landlords, and leasing professionals seeking clarity on tenancy areas before construction or fit-out begins — providing measurable data early in the decision-making process.

Why Use Desktop Area Analysis?

  • Early-Stage Insight – Understand projected areas before committing to design or construction.
  • Standardised Measurement – Fully compliant with PCA and IPMS standards for leasing accuracy.
  • Time & Cost Efficiency – Conducted entirely off-site, perfect for pre-lease assessments and feasibility studies.
  • Risk Reduction – Identify potential discrepancies early and avoid unexpected revisions and costs.
  • Decision Support – Receive clear, reliable area data to support leasing, asset management, and planning.

Our Process

1. Source Review
We assess your drawing application material which can include PDFs, CAD, Revit models to confirm quality, accuracy, and usability.

2. Measurement & Calculation
Using advanced CAD and digital measuring software, our team extracts and calculates lettable areas with precision and consistency.

3. QA & Compliance Check
Review and valdate calculations and standard alignment.

4. Delivery
We deliver a full area schedule and annotated drawings in PDF or DWG formats, ready for internal or client distribution.

Made for

  • Developers and Asset Managers – Evaluate proposed layouts and tenancy breakdowns before site work begins.
  • Leasing Agents – Confirm lettable areas to support negotiations and marketing materials.
  • Architects and Designers – Validate or compare designs against PCA and IPMS frameworks.

Frequently Asked Questions

What type of properties can a Desktop Area Analysis be carried out on?

A Desktop Area Analysis can be undertaken on all property types with the suitable source material.

What source material would be sufficient to carry out a DAA?

Drawing application packages in CAD & PDF preferred and most suitable. At the very minimum we require floor plans, external elevation & cross section drawings.

Why are external elevation & cross section drawings required for a Desktop Area Analysis?

External elevations and cross section drawings are important as they are the only means to determine the dominant portion along an external façade for area assessment. In all classes lease lines are set along the dominant portion of the guided surface.

What standards do you use for a Desktop Area Anslysis?

PCA Method of Measurement by default, IPMS on request.

Will the numbers on a DAA match a later PCA Survey?

DAA provides a strong baseline. Final figures may change if as-built conditions differ from the drawings supplied.

Do you need to visit site to complete a DAA?

No. DAA is completed from source material provided and usually done before any building has commenced.

How fast is turnaround?

Most DAA reports are delivered in 2-5 business, depending on quality of drawings and scope.
