Detail Surveys for Brisbane Development Projects

A detail survey, also called a topographic survey or feature survey, records the existing features and levels on a property so your architect, building designer or engineer can design around what is already there. It brings buildings and structures, trees, fences, driveways, visible services, ground levels and contours together on one base plan.

At City Surveyors Brisbane, detail and contour work can be quoted as one combined contour and detail survey, so the site features and the shape of the ground come in the same set of plans. Design teams use this survey data for new homes, extensions and renovations, multi-unit and subdivision planning, and drainage or earthworks design. If slope and levels are your main concern, our contour survey page explains that side of the survey in more detail.

Your proposal sets the exact scope for your property. As an example, a combined contour and detail survey quoted for a Brisbane property in March 2026 included:

Features & Structures

Existing buildings and infrastructure, plus heights and general detail including significant trees. The proposal also allowed for walls of adjoining buildings where possible or required.

AHD Levels & Contours

Detail and levels extending out to the front kerb line, with levels on the Australian Height Datum (AHD) and contours drawn from them.

Services & Boundary Ties

Locating visible services on site, with underground services plotted from records rather than detected. The proposal also specified ties to sufficient existing boundary marks, which is not the same as marking your boundaries. If your project needs existing underground services located or mapped for planned works, you can ask for a separate underground service locating and mapping quote.

PDF & AutoCAD 3D Files

The proposal specified PDF plans for viewing and AutoCAD 3D files for the design team. If your designer needs a different format, mention it when you ask for a quote.

When is a Detail Survey Required?

You usually need a detail survey when someone has to design around the existing site. Your architect, building designer or engineer will normally tell you what they need surveyed, and their brief is the best guide to choosing the right scope. Common situations include:

  • New homes, extensions and renovations that need an existing-conditions base plan
  • Multi-unit and subdivision planning that needs site features and levels
  • Drainage, retaining wall or earthworks design, where your engineer works from the levels
  • Development application plans that need to show existing features and levels

Detail Survey Cost in Brisbane

As an example, a combined contour and detail survey for a Brisbane property was quoted on 24 March 2026 at $2,915 including GST ($2,650 plus $265 GST). That one price covered both the detail and the contour work, with the scope listed above.

Your price depends on your site and the scope your designer needs, and you receive a fee proposal for your property before anything is booked. Sharing your designer's survey brief up front helps the proposal cover the features and levels they want.

What to Have Ready for Your Quote

  • The property address or suburb
  • Your designer's survey brief or any plans you already have, including features they want picked up
  • Preferred file formats, level datum and contour interval, if your designer has specified them
  • Your deadline and any site access notes, such as locked gates or pets

Frequently Asked Questions

What is included in a detail survey?
It depends on the scope your designer needs, and your proposal lists it. A combined contour and detail survey quoted for a Brisbane property in March 2026 specified existing buildings and infrastructure, heights and general detail including significant trees, adjoining building walls where possible or required, detail and levels out to the front kerb line, AHD levels and contours, and ties to sufficient boundary marks. The proposal provided for locating visible services and plotting underground services from records rather than detecting them, with PDF and AutoCAD 3D files as the specified outputs.
How much does a detail survey cost in Brisbane?
As an example, a combined contour and detail survey for a Brisbane property was quoted on 24 March 2026 at $2,915 including GST ($2,650 plus GST). That one price covered both the detail and contour work. For a price on your property, request a quote with the address and what your designer needs surveyed.
Do I need a detail survey for a development application?
Many projects do, because development application plans often need to show existing site features and levels. Your architect, town planner or certifier confirms what your application actually needs, so share their requirements when you ask for a quote and the survey scope can be set to match.
What's the difference between a detail survey and a boundary survey?
A boundary survey identifies and marks the legal boundaries of your property. A detail survey maps what is on the site, such as buildings, trees, levels and visible services, for design. A detail survey can be tied to existing boundary marks, but that does not re-mark your boundaries. If your project needs confirmed boundary positions, ask for boundary work to be quoted as well.
How long does a detail survey take to complete?
In March 2026, the estimated wait to start a combined contour and detail survey in Brisbane was about 1 to 2 weeks from engagement. That is the wait to start, not the delivery date. Current booking and delivery timing is confirmed with your proposal, so mention any deadline when you ask for a quote.
Can a detail survey help with drainage problems?
It can give your engineer or drainage designer the information they work from, including ground levels, contours and visible drainage features such as pits. The survey records the site as it is; it does not diagnose the problem or design the fix. If drainage is the main concern, ask your consultant which levels and features they need so the scope covers them.
Will I receive a digital copy of my detail survey?
The proposal for your property sets out the file formats. As an example, a March 2026 Brisbane proposal for a combined contour and detail survey specified PDF and AutoCAD 3D files. If your designer needs a particular format, mention it when you request a quote so it can be confirmed in your proposal.
