Measured Building Survey vs Feature & Level Survey in Victoria: Which Do You Need?

Builders, architects and building surveyors in Victoria often ask for a survey before design or a permit starts. The word covers two jobs. A measured building survey records the existing building. A feature and level survey records the site. Order the wrong one and the next person still does not have the drawing they need.

This guide covers what each survey captures, who orders it, when Victoria requires a licensed surveyor, and when a drafting measure is enough. It is for Melbourne and regional Victoria. It is not a fee guide, and it is not advice on your title.

What a measured building survey captures

A measured building survey records the building as it stands. Drafters also call the result an existing-conditions drawing or an as-built. The usual set is:

• Floor plans of each level in scope, with rooms, walls, openings and dimensions a designer can use
• Elevations of the relevant faces, with heights, windows, doors and the materials that are there
• Sections where ceiling heights, floor-to-floor heights or the roof form matter

It is a drawing of the building, prepared so someone can design or document from it. At Arya Designs this is a drafting measure: we visit, capture the building, and draw it up. Our guide to as-built drawings Melbourne walks through that same path.

Walls and fences can appear as physical features. That is not a definition of the title boundary. The survey answers "what is built?" It does not answer "where does the title end?"

What a feature and level survey captures

A feature and level survey, also called a detail or contour survey, records the site rather than the rooms. It is the base an architect, planner or engineer designs against, and it commonly shows:

• Site boundaries in context, including occupation on the ground and the title information the survey is based on
• Levels and contours, so falls, floor levels and drainage can be read
• Trees, often trunk and canopy where vegetation affects the design
• Services visible at the surface, such as pits, poles, meters and covers
• Fences, driveways, kerbs, retaining walls and other features in scope

This is land-survey work. In Victoria it is typically commissioned from a licensed land surveyor, especially for planning, engineering, or anything near a title boundary. The surveyor sets the method, the datum and the file format. The plan describes the land. It does not, by itself, give measured floor plans, elevations and sections of the building.

Who orders each survey

Measured building survey. Builders order it before a renovation or extension when the old plans are missing or wrong. Architects order it for existing floor plans, elevations and sections. Building surveyors may ask for that drawing in the set they assess. Owners and fitout designers order it when a shop, café or office has no plan. A council can require existing building plans with an application, even though the applicant commissions them.

Feature and level survey. Architects and engineers order it for levels, contours and site features on a new dwelling, a large extension or site works. Councils sit in this brief because a planning application may need levels, trees and neighbouring context. Builders order spot levels when the site is the unknown. Building surveyors may ask for site levels where the work depends on them.

A second storey, or a new house beside an existing one on a slope, often needs both: a feature and level survey of the land, and a measured building survey of the building. Scope them as two jobs.

When Victoria requires a licensed surveyor

The Surveyors Registration Board of Victoria describes cadastral surveying as the work of property boundaries: interpreting where a boundary lies and the rights in the land, and physically defining that boundary. The Board states that a surveyor registered as a licensed surveyor under the Surveying Act 2004 is the only person authorised to perform cadastral surveys in Victoria.

Land.vic.gov.au describes it as the definition or re-establishment of land-parcel boundaries, and states that a cadastral survey must be performed or supervised by a practising licensed surveyor. Re-establishing a boundary so the extent of the land can be determined is one of those surveys.

The Board's note on when you need a licensed surveyor is practical. You need one to know where your boundaries are, to build on or near them, to claim title by adverse possession, to subdivide, to create an easement, or to establish a building strata development.

The same page lists who is not a licensed surveyor: architects, building surveyors, builders, engineers, engineering surveyors, and people who produce plans. A building surveyor assesses building work. That registration is not a licence to define title. The Board states that an unlicensed boundary survey has no legal standing, and that undertaking one leaves the person liable for prosecution.

Levels, contours, trees and visible services are site information. Defining or re-establishing the title boundary is the part a licensed surveyor must perform or supervise. If a feature and level plan needs that re-establishment, confirm a licensed surveyor is responsible for it. We do not draw a title boundary and call it a survey.

When a drafting measure is enough

A drafting measure is enough when the question is the building. That is a renovation or extension that needs existing floor plans, and sometimes elevations or sections, before design. It is a shop, café or office that needs an existing-conditions plan for a fitout. It is an as-built for a design change or a redline, when the old plan is missing or not to scale. It is also a commercial measured survey for lease plans and asset records, where the lines are walls and tenancy lines, not title.

It is not enough for the legal position of a boundary, a re-establishment survey, a subdivision, or advice on whether the fence is the title line. We will say so. The next step is a licensed surveyor. Permit drawings are a separate question, covered in as-built drawings for Victorian building permits.

The laser scan option

A measured building survey is captured by traditional measure or by laser scan.

A traditional measure suits most houses, shops and hospitality tenancies and goes straight into CAD. A laser scan suits a building that is large, multi-level, heritage-detailed, or full of bulkheads and exposed services. The aim of either method is drawings. A point cloud can be included when the quote names it. The scan file alone is not the deliverable.

A laser scan is still a measured building survey. It is not a feature and level survey, and it does not re-establish title. See laser scanning versus a traditional site measure for which method suits the building.

DWG and PDF

Every measured building survey we prepare is delivered as DWG + PDF. The DWG is what your architect, builder or drafter works in. The PDF is for review, issue and lodgement. Agree the sheets first: floors, elevations, whether sections are included, and whether any immediate setting of the building is in scope. That setting is not a feature and level survey and not a title plan. If a feature and level survey also needs to arrive as CAD, ask that surveyor before they attend.

How to choose

1. Floor plans, elevations or sections. Measured building survey, provided nobody needs the title defined.
2. Levels, contours, trees, services or other site features. Feature and level survey, typically from a licensed land surveyor.
3. Title boundary, re-establishment, subdivision, easement, building on or near a boundary, adverse possession or strata. Cadastral work, performed or supervised by a licensed surveyor. Check the Board's register.
4. Building and site both. Two scopes. Finishing one does not finish the other.

If the request only says "as-built" or "survey", ask which sheets are expected. The sheet list is the brief.

How we can help

We prepare site measurement and as-built drawings in Melbourne for houses, tenancies and commercial buildings. We do not carry out cadastral surveys. If the brief is a feature and level survey or a title re-establishment, we say so before the wrong visit is booked.

Send the address and what the drawings are for. We confirm the product, and whether a traditional measure or a laser scan fits, then quote before we book. A call-out fee may apply for the site visit. You receive DWG + PDF.
