Land surveying services throughout your project life-cycle: Pre-application surveys, through setting out, construction monitoring to as-built land surveys

From our base in Shropshire, we offer Land Surveying services across the boundaries of Shropshire, the surrounding counties and the United Kingdom as a whole. Shropshire is a county tucked between the West Midlands and Wales and is one of the counties along the Welsh border that make up The Welsh Marches. While tucked away may imply small, Shropshire is anything but small. Shropshire is the largest inland county in England, covering 1,346 sq mi of land and taking over an hour to cross by car.

We offer land surveying services that cover the whole life cycle of a project. From pre-application surveys to setting out, inspection, construction site monitoring, and as-built surveys. All essential steps for successful project management.

Drone Land Surveys have become our technology mainstay as they are safer, quicker and cheaper than a traditional survey. We ensure our drone surveys adhere to the same land survey principles acquired through over 30 years of surveying experience.

What’s land surveying & do I need a land survey?

Land Surveying is the accurate collection of three-dimensional points and the relationship between them to map the topography of the Earth’s surface, be that:

  • above the ground – buildings and structures – from the ground or the air;
  • below the ground  – mine works or buried services;
  • above water – marine buildings and structures;
  • below water – lake, river and sea beds.

Professional Land Surveyors must be adept in several fields, including Mathematics, Physics, Engineering and Law. By using Geometry & Trigonometry, they can understand complex three-dimensional relationships. Physics to understand the movement and propagation of electromagnetic waves, to calculate distance and to understand hidden objects, often over long distances. Law to interpret and analyse boundary data in the event of a boundary dispute between neighbours.

Land surveyors can traced back to ancient civilizations like Egypt, Mesopotamia, and Rome. Early surveying techniques were primarily based on geometry, utilizing basic tools like ropes, wooden stakes, and plumb bobs to create accurate measurements. One notable example is the Egyptians, who used these methods to reestablish property boundaries after the Nile River flooded each year. These early land surveying practices laid the groundwork for more sophisticated techniques.

If you need to accurately understand the dimensions of a physical asset, land or its surroundings, then you could benefit from a land survey. Having accurate contextual information can be critical to the success of a project. Skimping on a survey can have detrimental and costly impacts on a project. We have been involved in many projects over the years where a land survey wasn’t commissioned in a project, only to be brought in later to fix a problem.

Why is a land survey important?

Land surveying is an important part of the development process. It is important because it provides information about the shape and size of your property or development, including the landform or terrain, land features, boundary features, heights of vegetation or structures, and the context of the site to determine its surroundings. Often, the information is shared as a 2d or 3d topographical survey drawing. Now, drones are becoming the norm for producing topographical surveys as they are faster, cheaper and more comprehensive.

Land surveying from a design perspective

It is important to know that your design/site layout can fit onto your site. A few years ago a client designed housing layouts with very tight design limits between houses, garages and other key features for conveyancing purposes. However, their design process produced many compound errors multiplied across the whole site. This meant the whole site rarely fitted on the ground compromising what they wanted to achieve. We can help you make sure your designs are correctly realised with accurate pre-application land surveys, setting out, progress monitoring and as-built land surveys, supporting you through the project life-cycle.

Land surveys from a boundary perspective

Disputes often arise from a misunderstanding of the accuracy of the title plan and the mapping that the title is drawn on. Land registry title plans use a scale of 1:1,250 while site plans for a planning application are more typically 1:500. Scaling up a plan from 1:1250 to 1:500 introduces problems and magnifies them. It should also be noted that The Land Registry does not check the legal boundaries of one title against neighbouring titles. So titles can actually overlap leading to neighbour disputes over a few inches. Instead, the Land Registry use thick lines designed to cover potential errors. In most cases, the red line on a title plan is in fact 2 meters wide on the ground. In America, this is largely avoided with cadastral surveys that show the real boundary positions. We can undertake a boundary survey to assist property owners and legal professionals should boundary problems arise.

Land surveys from an asset management perspective

Whatever your physical assets a Land Surveyor can map the context and position of those to aid in facilities management and asset management. Understanding what you have and where they are will cut maintenance costs, saving you time and money. From Lamppost and street furniture owned by local authorities to utility equipment owned by The National Grid or the Environment Agency, wind farms, solar farms and businesses within their premises, knowing the location and the condition of that equipment is important. We can help you map and manage your assets and facilities with an accurate land survey.

Land surveys from a planning perspective

An accurate land survey enables a designer to understand a site and its context in the surrounding topography, land features, built environment and landscape. The landscape setting is an important planning consideration for successful planning applications. A drone land survey widens that scope, allowing for an even greater understanding of your site. How can drone land surveys help with planning permissions?

For example, if you want us to measure or monitor a linear feature like a dam for lateral movement, it is important for us to design our control network to minimise survey errors along the axis of potential movement. It is also important to locate control points away from any areas of potential movement. Failure to do this will introduce accuracy errors in the data. This is particularly important when potential movements are small. Understanding baseline lengths, scale factors, the curvature of the earth and atmospheric conditions can also be critical depending on the size of a survey and the relative accuracy required.

Control points are important where repeat visits are needed, or a site will need to be set out at a later date. Triangulation networks use angles to calculate relative a position mathematically based on known points. Trilateration networks use distances to calculate relative a position mathematically based on known points. Satelite-based control points will only use trilateration based on one or more satellite constellations in orbit. Ground control networks will use a combination of triangulation and trilateration for a survey control network. Ideally, a combination of both triangulation and trilateration introduces redundancy into the control network and increases confidence. We will make sure our survey has the optimal network design for your project, whether large or small.

Is an Ordnance Survey plan good enough or accurate enough for my needs?

In short, it depends on what you are trying to achieve.

If you are after a relatively cheap plan where the relative accuracy of distances or proximity on-site isn’t critical, then an OS plan may be sufficient. For example, if you picture a small building in a large field. If the relative distance of the building to the boundary could vary by meters without having an impact then the OS plan would be OK.

If you still aren’t sure here are some FAQs to help you:

What is land surveying?

Land surveying is the science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. This process is essential for mapping, property boundary determination, construction, and legal documentation.

Why do I need a land survey?

A land survey is crucial when buying property, building on land, resolving property disputes, or dividing property. It ensures accurate property descriptions and compliance with local building regulations.

How much does a land survey cost?

The cost of a land survey varies depending on the size and complexity of the property, the type of survey required, and the property’s location. They can start from as little as £400 for a small site but it does depend on the time and equipment needed. Contact us for a detailed quote based on your specific needs.

How long does a land survey take?

The timeframe for a land survey can range from a few hours to several weeks, depending on the survey’s scope, property size, and terrain complexity. We strive to complete surveys as efficiently as possible while ensuring accuracy.

What types of land surveys are there?

There are several types of land surveys, including boundary surveys, topographic surveys, construction surveys, inland hydrographic surveys, and more. Each serves a specific purpose, from establishing property lines to preparing land for construction projects.

Do I need to be present during the survey?

While it’s not always necessary for the property owner to be present during the survey, it can be beneficial for clarifying boundaries, discussing property concerns, and ensuring all areas of interest are covered. The main priority is making sure the surveyors have free and unrestricted access to the site for the duration of the survey.

How do I prepare for a land survey?

Prepare for a land survey by providing any existing property documents, such as deeds or previous surveys, marking any known boundary markers, and ensuring clear access to the property and property boundaries where possible. Access problems can incur delays and extra costs, or the need to use extra specialist equipment. If you can foresee issues it is better to discuss those with us in advance.

Can a land survey affect my property taxes?

A land survey itself does not directly affect property taxes, but it can clarify the exact size and boundaries of your property, which could impact tax assessments based on land use and size.

What is included in a land survey report?

A land survey report typically includes a detailed map of the surveyed area, descriptions of property boundaries, and any relevant notes on topography, encroachments, or easements.

How do I commission a land survey with Crucial Services?
