What Is Included Your Topographical Land Survey?

On-Site Survey

Our expert site survey team will attend your property to conduct a thorough land survey, meticulously gathering all the vital measurements needed for your CAD drawings.

You have the option to supply us with your specific requirements, or you can rely on our extensive experience, honed from successfully completing numerous topographical survey projects over the years, to recommend the most suitable approach for your needs.

CAD Drawings & PDF's

We employ Autodesk’s industry-leading AutoCAD software to meticulously craft your site plans, sections, elevations, and more.

Over the years, we’ve refined our drawing package to optimise efficiency, allowing our clients to effortlessly integrate, manipulate, and expedite their design projects.

Key Features of Our Drawings:

  • Utilising layers, we meticulously organise the drawing, incorporating useful colour coding, line types, and line weights for ease of use.
  • We avoid overloading the drawings with superfluous details, rendering them more straightforward and easier to interpret.
  • Your survey and CAD drawings will be precisely aligned to Ordnance Survey grids. Additionally, we can incorporate extra mapping details into your drawings that fall outside our initial survey area, like local block plans.
     
  • Each drawing is subject to stringent quality checks prior to dispatch, eliminating any elements that could cause confusion.
  • We supply scaled PDF copies, making it convenient for printing and markup for those who may not have access to AutoCAD.

Survey Control Network

Utilising GPS RTK equipment, we align the topographical survey to the UK Ordnance Survey grid in both height and position. This allows the data to be aligned with other surveys or data provided by other mapping providers.

For elevation, we use OSTN15 and for position, we use OSGB36.

We leave fixed survey control stations on your site. These are usually in the form of nails driven into the ground or reflective targets left on buildings. Leaving these control stations here ensures future jobs such as setting out are undertaken with a high degree of accuracy.

Photographs From Site

During our visit to your property, we capture a series of photographs to assist us in the CAD drawing process. These images not only facilitate our work but can also be invaluable to you.

We offer to share this photo folder with you, which could serve multiple purposes. It can be a useful resource for future reference or even act as a compelling before-and-after record of your property.

For tips on how to effectively use photographs in your design projects, you may refer to this ArchDaily article.

FAQ's

The cost of a topographical survey can vary significantly depending on a number of factors, including the size of the area being surveyed, the level of detail required, the accessibility of the site, and the local market conditions.

In general, the cost of a topographical survey tends to be higher for larger sites, as more time and resources will be required to survey the entire area. The level of detail required for the survey can also affect the cost, as more detailed surveys will typically require more time and resources.

The accessibility of the site can also impact the cost of a topographical survey. Sites that are difficult to access, such as those that are located in remote or rugged areas, may require additional time and resources to survey, which can increase the overall cost.

Finally, local market conditions, such as the availability of surveyors and the level of demand for their services, can also impact the cost of a topographical survey.

It is difficult to provide a specific cost for a topographical survey without more information about the site and the level of detail required. However, as a rough estimate, the cost of a topographical survey can range from several hundred pounds for a small site with basic survey requirements, to several thousand pounds or more for a larger site with more detailed survey requirements.

Please visit our blog page on how much a topographical survey costs.

The amount of time required to complete a topographical survey can vary significantly depending on the size of the area being surveyed, the level of detail required and the accessibility of the site.

In general, smaller sites with fewer features will require less time to survey than larger sites with more complex features. The level of detail required for the survey can also impact the time required, as more detailed surveys will typically take longer to complete.

The accessibility of the site can also affect the time required to complete a topographical survey. Sites that are difficult to access, such as those that are located in remote or rugged areas, may require additional time to survey due to the added logistical challenges.

It is difficult to provide a specific time frame for a topographical survey without more information about the site and the level of detail required. However, as a rough estimate, a topographical survey for a small site with basic survey requirements may take a day or two to complete, while a larger site with more detailed survey requirements may take several days / weeks or more to survey.

 

Topographical surveys are typically undertaken using a combination of surveying instruments, including total stations, GPS receivers, levels, and hand-held laser scanners. These instruments are used to collect precise measurements and data about the features on the ground, such as the elevations, positions, and shapes of natural and man-made features.

There are several steps involved in the process of undertaking a topographical survey:

  1. Planning: The first step is to create a survey plan that outlines the scope of the survey and the level of detail required. This plan should include a list of the features that need to be surveyed, as well as any constraints or limitations that may impact the survey process.

  2. Measurement: The next step is to take precise measurements of the features on the ground using the appropriate surveying instruments. This may involve taking elevations, positions, and other measurements of the features, as well as collecting data about the shapes and sizes of these features.

  3. Data processing: Once the measurements have been collected, they must be processed to create a usable topographical survey. This typically involves aligning and merging multiple measurements, and cleaning up the data to remove any errors or inaccuracies.

  4. Mapping: The processed data can then be used to create a topographical map of the survey area, which shows the position and elevation of the features on the ground. This map may be created using specialized software or by hand using traditional cartographic techniques.

  5. Documentation: Finally, it is important to document the results of the topographical survey, including any measurements and calculations that were used, as well as any deviations from the survey plan that were discovered during the survey process.

Overall, the process of undertaking a topographical survey requires a combination of specialized equipment, software, and expertise to ensure that the resulting map is accurate and useful.

Topographical land surveys are used to create detailed maps of the natural and man-made features of a piece of land, including the elevations, positions, and shapes of these features. These maps are typically used for a wide range of projects, including:
