Utility Surveying
We specialise in utility surveys, accurately mapping underground utilities such as pipes, cables, and infrastructure. Our surveys help prevent utility strikes, facilitate planning and design, and enable efficient maintenance and asset management.
PAS128 Surveying
We offer PAS128-compliant utility surveys, adhering to industry standards for utility mapping and data classification. Our surveys provide accurate and standardised information on utility positions, depths, and attributes.
Topographical Surveying
Our topographical surveys provide detailed mapping of the natural and man-made features of your site. We capture precise measurements of contours, elevations, and features, supporting site planning, design, and construction projects.
Measured Building Surveying
Our measured building surveys deliver detailed measurements and plans of existing structures. Whether for renovation, space planning, or conservation purposes, our surveys provide essential information for informed decision-making.
GPR Surveying
Using ground-penetrating radar technology, we conduct subsurface mapping and detection of buried utilities, structures, and geological features. Our GPR surveys provide valuable information for construction, engineering, and environmental projects.
EV Charging GPR Survey
Twenty20 Surveys specialises in providing comprehensive services for the design and safe installation of Electric Vehicle (EV) charging sites. With their expertise in buried utility mapping and GPR Utility Surveys, they offer customised surveys to ensure informed decision-making and minimise risks.
What is a Utility Survey?
A Utility Survey is a non-invasive method of locating buried infrastructure that uses Electromagnetic Locators (EML) and Ground Penetrating Radar (GPR) to record the line, location, and depth of known, unknown, live, abandoned, metallic, and non-metallic utilities and present the results to the client in a simple and logical manner based on their specifications.
What is a Topographical Survey?
A Topographical Survey, sometimes referred to as a Land Survey, is the process required to produce an accurate and detailed map identifying both the natural and man-made feature within an area. The collected data may be presented in many formats, from a simple paper plan to a full three-dimensional (3D) digital model, depending on the client’s requirements. Today the most common presentation is as a digital data set which is also plotted out as drawings.
What is a Measured Building Survey?
A Measured Building Survey is the collection of measured data to enable the surveyor to be able to produce plans, elevations or sectional drawings of a building. Measured data can be delivered as two dimensional drawings but more commonly three dimensional ‘BIM ready’ solid or wireframe models are the requested deliverables.
What is a GPR Survey?
A Ground Penetrating Radar Survey, commonly referred to as a GPR Survey, is a non-intrusive geophysical locating technique that employs radio waves to image below the surface of the ground. GPR systems are commonly used to located buried utilities, structural features and voids.
