Building new structures and developing land are crucial, complicated processes that require heaps of hard work, precision and detailed steps. One critical step is to invest in professional topographical surveys to learn more about the unique plot of land that you’re working with. 

The shape of your land will strongly affect how you should design your new structure, handle risks, stay compliant with NZ regulations and so on. Having your land surveyed is a critical process that should never be skipped.

What Are Topographical Surveys?

A topographical survey is where professional surveyors gather information about a specific plot of land, capturing data about the natural contours of the land, any artificial features on the site, potential dangers to fix or mitigate, etc. Essentially, a topographical survey creates a ‘map’ of the site, including vital information that will guide the rest of your land development project.

Professional surveyors will help you, your architects, your builders and other important parties by providing you with everything you need to know about your land. Before you change any part of your property, whether that be earthworks or building a new house, you need to understand what you’re working with.

Why Are Topographical Surveys Important For Construction And Land Development Projects?

How exactly can a topographical survey benefit your NZ project?

Supporting Innovative Engineering Design. The information provided by your surveyors is the foundation on which the rest of the land project will be built. Surveys provide crucial information on land contours, infrastructure, boundaries and much more. This information guides important future decisions about engineering, construction, architectural design, infrastructure design and many other vital factors. 

Without this guidance, your designs may not work, your architectural plans may be dangerous and your project may not have the results you’re dreaming of. Topographical surveys strongly impact your team’s construction methods and design choices for your build. For example, building on a slope requires different methods than building on flat land. If your survey reveals that your land is sloped, you can choose the proper techniques to ensure your new structure is stable.

Testing For Feasibility. Not all designs work on all kinds of land. Before you start any kind of construction, you need to make sure your idea suits your particular property. A surveyor can analyse your land’s potential dangers, natural features, underground structures and more to tell you if they think your vision will work with your land. 

If the land is right for you, then you can use the data gathered by the survey to bring out the full potential of your land and your new structure. If the land is not suitable for your vision, then you can decide what’s best for your goals – change your plans or secure another plot of land. 

Boundary Identification. You absolutely must establish your site’s boundaries before you do any kind of work, regardless of how grand your plans are. Why is this so important?

  • Avoiding Boundary Encroachment. You can get in trouble if you build your new structure onto your neighbour’s land. If you do this, you could face fines and you will have to alter your build to fix the problem. This entire issue is expensive, time-consuming and frustrating. Instead, invest in topographical surveys so you know where your property lines are. 
  • Guiding Development Plans. Your architects, builders and other involved professionals need to know the size and placement of the land they’re working with so they can create designs that fit your space. If they don’t know the dimensions of your land, they could end up making plans that are unsuitable for your land. 
  • Ensuring Privacy And Spacing. You should make sure your new structure is positioned properly on your land. A new home too close to your boundary lines could be too close to your neighbour’s house, hindering your and your neighbour’s privacy. 

Once you learn where your property lines are, you can build a fence inside of your boundaries to help define your land. Plus, fences will add extra security, property value and aesthetic appeal.

Risk Management. Construction and land development come with plenty of potential dangers. Uneven land, flood risks, site contamination and more can all put your team – and your future structure – in danger. One of the best ways to handle danger is to identify it and understand it so you can either eliminate the issues or manage them to prevent accidents. Topographical surveys help to identify all risks on a piece of land. Once your surveyor gives you all of the details about potential problems, then you and your team can discuss the best ways to handle them. Taking proactive measures now can prevent serious incidents in the future.
