Over the years, our expertise has been applied to an eclectic mix of projects, ranging from solar farms to quaint plots of land in domestic gardens!
How Do We Survey Your Land?
Before embarking on any survey, we initiate an in-depth consultation with our clients to understand their specific project needs. Given that each project often demands different levels of detail in various areas, our methodology is customised to address these individual requirements.
Our topographical survey service is engineered to capture a wide array of site elements, depending on your unique needs. These elements typically include walls, spot heights, trees, fence lines, and more.
For projects that require a more intricate level of detail, our survey can be expanded to include additional features, such as drainage systems, utility lines, and other site-specific elements.
What Is Included Your Land 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.
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.
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.
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.
We ensure you are 100% happy with the measured survey drawings we provide. If there are any issues, then we are more than happy to rectify these free of charge. This may include re-visiting the site or addressing something in the drawings.
In the event that you are still not satisfied with our services, we offer a 100% money-back guarantee.
