ADAC for As Constructed Water and Sewer handover

What is ADAC?

ADAC stands for “Asset Design and As Constructed”. It is the name given to a non-proprietary data specification and allows standardised electronic transfer of asset design and as-constructed data between asset constructors and asset owners. It is developed and maintained by the Institute of Public Works Engineering Australasia, Queensland Division (IPWEAQ), in conjunction with a consortium of Local Government agencies in Queensland.

We use the ADAC XML schema definition in conjunction with a feature manipulation engine (Extract, Transform and Load / ETL) tool to map data from electronic design and ‘as-constructed’ drawings to data fields within our asset data register and GIS systems.

ADAC Capture Guidelines

We have prepared the ADAC data capture guidelines to guide and help with the creation and provision of compliant as-constructed infrastructure data and ADAC XML files.

Compliant ADAC XML files contain a structured and precise digital record of the assets described in the “As-Constructed” plans and other associated engineering documentation.

Details include survey-accurate cadastral and boundary references, geometries and relative levels as well as detailed asset records and required attributes.

ADAC and Logan Planning Scheme

Schedules 6, PSP 5, Part 5.6 of the Logan Planning Scheme require compliant ADAC XML files to be lodged for all assets classes including:

  • Transport
  • Stormwater drainage
  • Open Space
  • Water Supply
  • Sewerage

This is included in the As-Constructed information we require as a part of the handover of nominated works and associated donated civil assets and infrastructure.

ADAC for Water Supply and Sewerage Infrastructure Assets

The provision of compliant ADAC XML files has been a requirement for all water supply and sewerage infrastructure assets since 1 July 2013, when the Queensland Government legislated the South East Queensland Water Supply and Sewerage Design and Construction Code (or the SEQ Code).

The SEQ Code applies to all planning, designing and construction of these assets. It is of interest to:

  • developers
  • engineers
  • consultants
  • constructors
  • product suppliers, and
  • anyone who donates or constructs these assets which will be owned by Councils in South East Queensland.

One of the key deliverables of the SEQ Code is Asset Information Specification (SEQ Code AIS). It specifies the quality, type, format, and completeness of information package required to be submitted by land developers. This package includes the submission of a compliant ADAC XML file for all new developments.

ADAC XML files exemptions

Any development that creates equal to or less than fifty (50) meters of water supply, sewerage or stormwater infrastructure or equal to or less than four (4) lots will not need to submit a compliant ADAC XML file, .

With the exception of water supply and sewerage infrastructure, Logan City Council may accept alternative types of as constructed file formats, depending on the nature works undertaken, including:

  • Electric drawing file with ADAC attributes
  • Mud / Sketch with Asset Characteristic List

Please refer to the Logan City Council ADAC Capture Guidelines for more information.

Non-Compliant ADAC XML Criteria

The ADAC XML file is not compliant if it does not conform with the schema and data definition outlined in the xsd files for the most recent ADAC Version available from IPWEA.

For water supply and sewerage infrastructure, the ADAC XML file is also not compliant if it is not conformed with the requirements of the most current SEQ Code AIS.

ADAC version and effective date

The current version of ADAC is 5.01. Council may accept ADAC XML files in the version of 4.2 format for non-water supply and non-sewerage infrastructure subject to the conditions of the planning approval.

For any Operational Works Approvals granted from 1 July 2023, compliant ADAC XML files are to be lodged for all asset classes in the latest version of 5.01 format.
