If you’ve ever wondered about how we keep our structures safe from natural or man-made changes, you’ve likely stumbled upon the concept of a ‘deformation survey.’ But what exactly is a deformation survey, and what purpose does it serve? Let’s take a closer look.
What Is a Deformation Survey?
Simply put, a deformation survey is a specific type of survey designed to measure and record changes in an object’s shape or dimensions. Whether it’s a building, a dam, or a piece of land, a deformation survey can monitor and record any changes over time. These changes could be due to various factors such as weathering, geological activities, or human interventions.
The Critical Role of Deformation Surveys
So why are deformation surveys so crucial? The answer lies in their capacity to provide early warnings for potential problems. Deformation surveys can detect shifts in structures that could lead to significant issues if not addressed promptly. This could be a building starting to lean dangerously, a dam developing small but consequential cracks, or a tunnel beginning to warp.
By identifying these issues early, action can be taken to correct them and prevent more significant problems down the line, such as structural failure that could lead to accidents or even loss of life.
Where have deformation surveys been used in the UK?
While Midland Survey takes on an array of different-sized projects, we are always looking at how the industry is utilising surveying as an optimal tool during the building phase.
Let’s talk about how important deformation surveys are in some of the UK’s biggest projects that have caught our eye.
Crossrail Project
This is a really big deal for the UK’s infrastructure. During the building phase, these surveys played a big part in making sure the tunnels were safe and sturdy. They also helped us spot any problems with the structure or the land around the works, which was super useful.
Hinkley Point C Nuclear Power Station in Somerset.
This new power station used deformation surveys a lot during construction. They helped keep an eye on any shifting in the land and made sure everything was structurally sound.
High Speed 2 (HS2) project.
This is a major high-speed rail network that will connect London with cities up north. During the build, deformation surveys were used to check on structures, hills, and cuttings to make sure everything was stable and good to go.
The Shard in London.
During its build, deformation surveys were used to watch for any movement in the structure and to see how it affected the buildings around it. It’s all about making sure everything is safe and sound.
How a deformation survey can work for your project
Through the use of advanced technologies such as GPS and total stations, surveyors at Midland Survey can monitor and measure even the smallest changes in a structure’s position. This information can then be used to create detailed maps and models that clearly highlight any deformation that has occurred.
How to plan your project’s deformation survey
Unsurprisingly, it is an essential tool for maintaining the safety and integrity of our built and natural environments. Whether it’s the Midland Survey team monitoring changes or you making adjustments to your project because of the data shown, the use of deformation surveys is critical in keeping us and our structures safe.
