Format Guidelines for DAs
The guide below lists those documents, plans and drawings you should provide with your Development Application (DA).
Including the right information in the right format can help avoid delays or extra costs.
You should provide digital copies of all plans, drawings and documents when submitting a DA.
Note: From 1 July 2020, all applications must be made online via the NSW Planning Portal. Hard copy applications will no longer be accepted.
- Each document or plan should be saved as a separate file. The only exception to this is elevation plans, shadow plans, stormwater layouts and some landscape plans, as well as bulk earthwork, typical road cross sections, road longitudinal sections which can be multiple pages.
- Files must be provided in PDF (portable document format).
- Photos should be in JPEG format.
- Each file should be no larger than 10MB. Any files over 10MB will need to be split into separate smaller files.
Drawings and plans should be:
- To scale, usually at a ratio of 1:100
- Numbered, titled and dated
- Dimensions should be shown.
If your development is in the Wollongong City Centre and will be four storeys high or more, your DA will need to include a 3D CAD model of the building.
Fees apply for submitting or updating a 3D model. You need to provide the 3D model as described below. Make sure you follow these rules carefully. If the 3D CAD model isn’t provided correctly, you will have to resubmit it, and re-pay any fees.
Detailed model of development site and buildings
A 1:1 scale detailed 3D CAD model is required, showing a realistic and accurate 3D representation of the exterior of the whole development. This should include:
- Site details: landscaped areas, driveways, access ramps, pedestrian access ways, car parking, major signage or similar structures, bridges, street overpasses and any other significant features.
- Building details. everything of significance for each elevation, including all protrusions and indents like balconies, porticos, parapets, etc.
- Roof details: all external detail including pitch, protrusions such as plant enclosures, fire stairs, terraces, shade roofs, signage structures, flag poles or similar.
- Do not include any interior details, text, dimensions, hatching or area fill.
Accepted CAD formats
3D models should be provided as AutoCAD 3D DWG or Autodesk 3DS format.
Contact us before submitting to discuss alternative acceptable file formats.
All relevant data must be bound within the submitted 3D CAD model. Do not include any reference or cross-reference points or external files.
Layer and level names
Layer names must be descriptive and logical. Do not use numerical-only layer names.
Naming conventions used should be clearly defined in the documentation submitted with the model.
Rendering of the model
Surface material renders and building facades should be supplied as raster images in separate files, and must indicate the model face the image applies to and method of applying the image (eg full faced or tiled).
