CAT Survey – Carrying Out Site Investigations

A CAT survey is just one of the many surveys that you can have carried out to determine the location of underground utilities and services.  These are usually run in conjunction with a GPR survey. CAT surveys are necessities for the construction industry, but they can help in other job roles too – from engineers to architects. The key is to find an experienced and professional company that can carry out these surveys for you, ensuring you get all the information you need in a timely manner. With that in mind, read on to discover everything you need to know.

Understanding CAT Scan Site Investigations

A CAT scan ground survey is one of the most important tests that need to be carried out when determining whether a site is suitable and what potential changes need to be made. A CAT scan is an sub-surface surveying technique that is key in locating any below-ground utilities prior to construction processes such as piling, drilling, and excavations. By using electromagnetic equipment, the company you hire can complete a full site investigation to position and identify underground services. All this data can then be shown on a CAD drawing, combined with a land or topographical survey, or can be marked up on site.  There are other services that can be combined with this, such as GPR surveys.

Understanding Electromagnetic Location (EML)

Electromagnetic location (EML) involves inducing a signal of known frequency into a service, (usually at a termination point) that can be followed, or “traced” using a receiver set to the same frequency. With the correct equipment and methodology, the depth can also be interpreted. As each service is found and traced marks are sprayed onto the ground directly above, along with the corresponding depth. Each service type is given a different colour to help distinguish it from the others, making it easier to follow.

Who Can Carry Out A CAT Survey Test for Your Business?

There are numerous companies that provide land and utility surveys. However, you do not want to leave this in the hands of someone who does not have the necessary experience of undertaking a CAT survey. You need a business that fully understands how important their service is when it comes to avoiding potential accidents and costly damage later down the line. In many cases, you need to combine several different surveys and services, and so the best firm can adapt their offering based on this. Not only should you make sure the company is experienced, and this means the people behind the company, but you need to make sure they are compliant and that they can provide you with an accurate and detailed quote, so you know exactly what you are paying for. Do a bit of digging online to find the best company for you and always read feedback that has been left by previous clients.
