Often called contour surveys, detail surveys, terrain surveys, topographic surveys or topo surveys, topographical surveys are laser-measured land surveys that gather data about natural and man-made features on your site with high accuracy, including the topography and elevation of your land.
A topographical survey will also precisely locate all salient land features such as drainage ditches, existing buildings, service cover positions, site and spot levels, site boundaries, trees and tree positions, and walkways. We normally present this data digitally and in CAD format to present an accurate depiction of the land with all site features outlined, as well as features adjacent to the site.
The additional information gathered from a topographical survey gives you, your planning team and the local authority the insights needed about the land you are looking to build on. As with many circumstances, knowledge is power, so having not only the correct information but the correct information early will benefit your project in numerous ways.
Investing in your development is complex, and incorporating certain components will contribute to a successful end result. Through a quick and accurate topographic survey, you can significantly decrease the level of risk. Features of a topographical survey that contribute to a project include:
In simple terms, a topographical survey protects you from unforeseen issues with the specific area of land, your site or your plans that you may have otherwise been unaware of. Additionally, an early topographic land survey will help you to refine your designs and adjust your plans, helping you to save considerable time and reduce cost while avoiding delays and disappointment.
The different types of information retrieved from a topographical survey can have a material impact on your development. For instance, it could make you aware of a need for additional surveys – such as tree surveys – well in advance of you submitting your planning application, thereby avoiding risk of delay when the local authority inevitably asks for one. Likewise, if there are unstable ground surfaces, the information from a topo survey can change how you approach drainage details, the choice of foundation, or even the design itself.
By bringing together a selection of three-dimensional points of data into easily digestible maps, models, and charts, a topographic survey will help you avoid the avoidable and exploit the exploitable.
Topographic surveys will enable you to:
Although the list above only highlights a few of the practical benefits from booking this type of assessment on your site, in the majority of cases, the pros to getting a topographical survey outweigh the risks of costly mistakes caused by not getting one. In any development, your time and money are at stake, so seeing the ‘full picture’ of your site and all present potential construction difficulties will help in reducing the risk of various elements going wrong later in the process.
Every development presents different planning and design challenges, and this means that, unfortunately, there is no one-size-fits-all answer. However, what we can say is that the larger or more complex your development, the greater the likely need for a topographical survey, particularly if the site is developed and could be housing hidden features.
If your plans are wide-ranging and involve multiple builds spread out over a large brownfield site, the chances of you encountering something potentially problematic are fairly high. That said, you could just as easily run into difficulties partway through building if, for example, it turns out that the ground on your open terrain site is more sloped than you thought it was.
Ultimately, determining the need for topo surveys is a question of risk, and it is important to stress that you don’t know what you don’t know. Therefore, it is perhaps helpful to view your topographical survey as an investment, as it will act as an opportunity for land surveyors to tell you everything you need to know about the area of land you are planning to build on, helping you make all the right decisions.
If you are in need of a topographical survey and don’t get one conducted on your side, the consequences could include any number of issues, ranging from the relatively minor to the profound and catastrophic.
In terms of the less serious end of the spectrum, issues could involve boundary issues that could lead the local authority to refuse planning permission in the first instance. While this is inconvenient, it is not the end of the world and another planning application can be put forward once the necessary adjustments have been made.
Looking at the more serious end of the spectrum, building too close to a retaining wall could cause a total structural collapse. But as you aren’t an expert in construction, you won’t know exactly what ‘too close’ is classed as without a topographical survey.
A concerning factor about any land development is that a lot of the unforeseen issues a land survey will uncover aren’t immediately apparent during the building process. In fact, unless it is something dramatic like a 20% incline or a well signposted disused mineshaft, things can appear completely normal. As such, if you take a risk by not getting a topographical survey, you could face the costly mistakes caused by this decision months or even years after your development is finished.
Though not as frustrating as a refused planning application or as dramatic as a collapsed building, there are other consequences of ignoring the need for a topographical survey, such as missing out on opportunities for your site and project. Although it can be sensible to approach a development in a risk-averse manner, lacking the insights from a topographical survey could lead you to limiting your aspirations due to a lack of knowledge on the man-made and natural topographic features on your site to such an extent that the development suffers or doesn’t reach its fullest potential.
As well as showing you what you can’t do, land surveys will also show you what you can do. Land surveys aren’t only there to warn you of danger; they will also utilise detailed information from your entire site to give you and your planning team the necessary assurances, helping you to explore development opportunities you may have initially dismissed as unworkable.
From design to completion, a topographical land survey will be the sound foundation you need to see all site features on your area of land. You can get some small, domestic designs through planning without one, but if you want to make the most of your development and get planning consent without getting dragged through the mire of rejections and committees, it would be wise to consider a topographical survey.
After booking an assessment, the process of undertaking a topographic survey is relatively straightforward, following a similar format to other building and land surveys such as a 3D survey, condition report, measured survey, utility survey or visual impact assessment.
It all starts with a discussion where we will ask you about your site, what you want to achieve and how you are currently planning to go about it. From there, we will be able to use your specific needs to help determine the level of detail your land survey will need to go into.
One or more of our experts will then visit your site and set up highly specialised survey equipment to carry out the survey. Common tools used for topo surveys include cameras, GPS devices, laser scanning instruments, site levels and total stations. With the necessary survey equipment, the land surveyor will capture the exact best fit measurements and other data, and create an accurate picture of the map of your site.
The difficulty of the survey will be dependent on the nature of the site. In some cases, the site may be hard, or even impossible, to fully cover on foot. Different types of natural features on the site can act as obstacles, such as offshore islands, steel inclines, ravines or simply the physical geography of the area. Man-made features can also pose a hindrance to the survey, such as busy roads, existing buildings, partially collapsed structures or power stations. If it is too difficult to reach certain areas of the site, the land surveyor will use other forms of highly specialised survey equipment such as drones that can be used for taking photographs or laser scanning.
Other information may be retrieved before or after the site visit using other means such as from an Ordnance Survey or records from the local authority. Most of the topographical survey work we do is to facilitate design-stage activity. This is because your architect and/or design team will need CAD drawings and pinpoint accurate site measurements to create feasible plans.
The gathered data can then be used by your land surveyor to create AutoCAD drawings using point cloud technology (also sent to you as a PDF). Topographic features on the accurate picture may be displayed as:
