Land Surveying – what is it and why is it important?
There are a range of property professionals at your disposal and, in most cases, you’ll recognise them by name.
Today, I’d like talk about land surveyors. They’re great professionals to have on your speed dial, but you may not be utilising their full range of services to your best advantage.
What is land surveying and what do land surveyors check for?
If you’re buying a property with the intention of developing or significantly renovating, you need to know about land surveying.
You’ve probably seen surveyors in the field as you drive to work. They’re the ones in hard hats who’re often looking through telescopic machines set on tripods – gazing to the horizon or concentrating on a height staff being held by their apprentice.
Land surveyors actually work on a diverse variety of projects from planning and design of new or existing infrastructure, land and building development, construction (buildings, roads, bridges, sports fields, farming, etc.), to monitoring and environmental measuring.
They’re experts in determining land size and measurements, as well as topographic heights. The surveyor gives advice and provides information to guide the work of engineers, architects, town planners, geologists and developers. They also work with all levels of government as well as service authorities such as water, sewer and power authorities.
Surveyors are often the first people on any construction or development site, measuring and mapping the land. Their measurements are then used by architects to understand and make the most of the landscape when designing, and engineers to plan structures accurately and safely – ensuring buildings not only fit with the landscape but are able to be constructed.
Their work forms the foundational information upon which many of plans are created to ensure the form and function of projects meet the brief.
Why do renovators and developers need their land surveyed?
Accurately understanding the dimension and topography of any site is key to ensuring what you plan to achieve will comply with building guidelines, town plans and the end goal of your project.
For example, if your structural renovation or development project requires constructing new rooms or additional dwellings after subdividing a block, you need to understand whether everything will fit on the site. You must also ensure you adhere to all town planning codes, like the wall distance from property’s boundary line.
In addition, if you’re proposing to build, renovate, develop, subdivide, or change the land use, a planning permit might be required. These are lodged with the relevant local government department and are assessed against the land zoning, permitted land uses, overlays, municipal strategic statements and various other planning documents. To make your case, a professional survey is going to be mandatory.
It’s important to understand there are a whole host of different zones that allow for different land uses to be conducted. There also may be overlays such as wildfire, heritage, vegetation protection on the land as well as particular local provisions such as minimum and maximum land size for subdivision, building heights and plot ratio that you need to know. Having your boundary lines and topographic heights accurately measured on a plan ensures you can address and accommodate all of these issues while still completing the project you plan.
What is an Existing Conditions Survey?
So, for structural renovation or development projects, a type of survey may be required, which is called an Existing Conditions Survey. It also can be known as a site and context plan.
A qualified land surveyor will survey the site to provide information including the location of features such as buildings, vegetation and fences, the slope of the land, building heights, road features and any utility services that are currently present.
If your project requires a town planning application, the adjoining property buildings are also surveyed including the location of habitable windows, doors, roof ridgelines and eaves.
The land surveyor may also have to carry out a title re-establishment survey to determine the exact location of the property boundaries because sometimes the boundary is different to the existing fence lines. Of course, this survey is necessary if any of your proposed works are near the boundary.
In areas close to waterways, or in flatter parts of land, the location and heights of drainage and sewer infrastructure is also vitally important. This information can often determine future dwelling floor levels or the ability of increased density developments to be serviced as existing infrastructure may not have capacity.
What is a Cadastral survey?
A term you may come across frequently when researching surveyors is ‘cadastral’. A cadastral surveyor is one who specifically undertakes surveys in relation to boundaries/perimeters of parcels of land.
If you are seeking to sub-divide land, or embark upon a renovation that extends the property structure towards the boundary, then a cadastral surveyor is the type of surveyor you need.
A cadastral surveyor gives advice on the status of land, and any interests or restrictions attached to property.
A cadastral survey report is used to facilitate the transfer of property.
What happens to the land survey information?
By using specialised equipment such as levels, electronic theodolites, tapes and Global Navigation Satellite System (GNSS) units, surveyors can accurately measure land and define boundaries.
Once they have surveyed a property, they draw up a plan for their client and if necessary, lodge the subdivision plan with Land Victoria or the equivalent State Government department.
The boundaries registered by land surveyors are then recorded in the State’s land information system, which includes the boundaries of privately owned and government land, survey plans, survey field records, ownership information, easements and other land information.
What do surveyors check for?
Surveyors measure and check the land, including formations, slopes, features, heights, to create a detailed report which includes a map of the land.
The importance of land surveying can not be overstated. Having a complete set of data and information at your disposal will help with making informed decisions about the property.
A land survey will ensure boundaries are where you think they are (sometimes they aren’t!) and will ensure all features are accounted for when making planning decisions.
Why you must use a licensed surveyor
In Victoria, licensed surveyors are registered by the Surveyors Registration Board of Victoria (SRBV). Each state and territory has its own governing body.
The SRBV is a statutory body responsible for establishing and maintaining the competency and educational standards for licensed surveyors, maintaining a register of licensed surveyors and managing disciplinary procedures.
A licensed surveyor is the only person legally entitled to undertake a survey to mark the boundaries of your property.
A licensed surveyor will define your land boundaries and upon request should provide a certified plan that confirms the work has been completed correctly.
It’s vitally important to understand that surveys prepared by non-licensed surveyors do not have legal standing and will not be recognised as evidence in the event of a boundary dispute.
It’s not worth the risk, so make sure you only use a licensed professional to survey your land.
Non-licensed surveyors are able to carry out many other forms of surveying including Existing Conditions Surveys, engineering, construction, environmental and monitoring surveys.
How much does land surveying cost?
Fees for land surveying can range anywhere from approximately $375 to tens of thousands of dollars depending on the scope of works required. On average, surveyors base-line fees will come in around $450 to $500 for basic jobs.
When calculating the total surveying costs, a number of factors have to be considered including:
- Site location — The area where the property is located directly affects the price. You may be charged a higher rate if there are plenty of trees present or if the property is not easily accessible to vehicles.
- Size of the property — The larger the property, the longer it will take to survey the land.
- Shape of the property — It is cheaper to have a rectangular-sized property measured and surveyed compared to a piece of land with irregular borders.
- Physical features of the land — You may be charged higher surveying rates for properties located in a mountainous terrain with plenty of foliage. Apart from the difficulty of surveying these lands, they’re not easily accessible as well.
Given a structural renovation or development costs tens or hundreds of thousands of dollars, the cost of having the land professionally surveyed is small change in comparison to the total project cost, isn’t it?
Do I need a land survey when buying a house?
In most states there is no legal obligation to have a land survey done when buying or selling a house. However, it’s usually a good idea. And from time to time the lender may request a land survey, for a range of reasons. And a land survey can be a prudent decision to identify additional information about the property.
A land survey can give you exact details about where the boundaries of the property are. If the documents provided by the vendor don’t give clear or precise information, then a land survey may be helpful.
Where you are more likely to need a land survey is if you’re refinancing, or planning to sub-divide the property. Then a land survey is required, usually by the lender.
If you are doing any construction, either building a house or adding an extension, or building a fence, you may need a land survey to clearly delineate setbacks and boundaries.
Set out Surveys for construction, engineering, and development
Often when any new, improved, or upgraded development (building, road, oval, bridge etc.) is to be constructed, the exact locations of these works are required to be set out by a surveyor.
They can be as simple as setting out a reference line to allow builders to position the building, although modern construction techniques allow for more detailed and intricately shaped buildings (often constructed off-site), so the need for precise set out is invaluable.
On a sloped site, surveyor’s equipment can measure horizontal distances. This is incredibly useful for builders who don’t often have access to the specialised hardware for these measurements. With the correct setup, the land surveyor’s equipment can measure distances to within a few millimetres. They can also measure vertical distances which are invaluable in providing for cut and fill measurements when constructing a road, drain, or for setting out an excavation for a pipeline.
Having the right set out data at the outset is so important as it provides surety to the construction teams, reduces time loss, and allows those on site to do what they are experts in.
Land surveyors can also use their knowledge to double-check design plans and create survey plans that have all information required for the set-out of the construction.
Surveyors will work with a project’s other professionals and contractors too, so as to determine what set out information is required. This allows the construction team to have a ‘plan of attack’ prior to site visits, helping minimise delays and making the process more efficient.
When the set out is complete surveyors can ensure a site handover is carried out, and provide set out plans for reference.
