ADAC/A-SPEC Data Done Right — First Time, Every Time

What is ADAC or A-SPEC?

ADAC (QLD) and A-SPEC (WA) stands for Asset Specification — a national standard used across Australia to capture and deliver “As Constructed” infrastructure asset data in a consistent, GIS-ready format. It covers a wide range of assets including roads, drainage, lighting, open space, and more.

By standardising how asset data is collected and shared, ADAC/A-SPEC helps councils and asset managers reduce errors, improve data quality, and streamline asset management.

Why ESO?

At ESO, we combine deep surveying expertise with ADAC and A-SPEC know-how to ensure your datasets are right the first time — meaning fewer revisions, reduced costs, and faster project delivery.

We proudly offer ADAC or A-SPEC services across Queensland (QLD) and Western Australia (WA), supporting councils and asset managers with reliable, compliant data that drives smarter decisions.

Our ADAC & A-SPEC Workflow

Here’s how we deliver accurate, compliant datasets — every time:

  1. Field Data Capture
    Our experienced surveyors collect detailed asset data on-site using high-precision equipment, ensuring all features are captured in line with council requirements.
  2. Client Checklist
    We send a tailored checklist to confirm which A-SPEC specification (e.g. Open Space, Drainage, Roads, Other Assets) or ADAC asset classes (e.g. Water, Sewer, Stormwater, Roads, Open Space) are required.
  3. Database Creation
    Using 12d Model, we build the asset database and structure it for compliance. The data is then prepared for delivery in the required format — GIS datasets for A-SPEC, or XML/GML files for ADAC.
  4. Data Analysis & Attribution
    Each asset type is analysed and assigned multiple attributes — such as material, dimensions, condition, and installation details — in line with the relevant A-SPEC or ADAC standards.
  5. Review & Delivery
    The dataset is coordinated, quality-checked, validated against the applicable specification, and sent to the asset owner for final review and acceptance.

What You Get:

  • Accurate, GIS-ready datasets
  • Reduced rework and project delays
  • Trusted by councils and asset managers nationwide

Whether you’re a long-time client or exploring ADAC or A-SPEC for the first time, ESO is here to help you get the most out of your data — and your investment.
