Why Use CAD in Measured Building Surveys?

December 11, 2019

A measured building survey is a record of a building’s dimensions, detailing all structural and architectural elements, which is why it is so important to ensure complete accuracy.

At South West Surveys, when we create measured building surveys, we pride ourselves on making sure all 3D images are illustrated with the greatest detail and accuracy, from skirting, to coving, to ceiling lights. To do this, we use CAD (computer-aided design) software.

What is CAD software?

CAD is a software used to make, alter, or analyse a design, using geometrical parameters to create a realistic representation of a proposed finished product or building. CAD software is popular among engineers, architects and surveyors for making floorplans and construction diagrams, but is also widely used across many industries, where precise technical drawings are required.

It can be used to produce either 2D or 3D drawings/models, which can be rotated and viewed from any angle. 2D CAD is a more traditional process of drafting, whilst 3D CAD/BIM (Building Information Modelling) can be a more efficient method.

What are the benefits of using CAD?

  • Flexibility – CAD models can be easily altered to fit new data and parameters, making it a particularly adaptable option.
  • Time-effective – using CAD software is generally considered to be a better use of a designer’s time, creating more accurate designs in a shorter timeframe.
  • Improved accuracy – the precision that laser scanning technology and CAD software provide leads to highly accurate measured building surveys, eradicating manual errors that are inevitable with hand-drawn sketches.
  • Easily editable – as a tool that is often used for design modifications and optimisation.
  • Easy to share – making collaboration easier, CAD is a more convenient way of sharing, saving and finding files.

Put simply, CAD modelling provides us with a more efficient way of working, whilst continually raising our standards.

At South West Surveys, we present our measured surveys in CAD software, but can also provide paper and film copies if requested.

What is CAD used for in the surveying sector?

CAD is a software rapidly growing in popularity and is used across a spectrum of projects, from building surveys, to engineering and construction works, to topographical surveys. Its range of applications spans from simple one-off uses, to more complex long-term projects.

What is the difference between CAD and AutoCAD?

CAD stands for computer-aided design, this the practise of using a computer to create technical drawings such a surveys and plans. The difference between the two is that AutoCAD is a brand of professional software which can be used to create 2D and 3D drawings and models. It is used by professionals such as construction planners, architects and engineers to help create precise plans.
While 2D CAD is more traditional in drawing up plans, 3D CAD can provide a higher level of detail and depth to plans to help with accuracy and visualising plans. CAD models are used because they are flexible to adapt and can be easily altered if needed as well as much more time-effective.

AutoCAD is a specialist and expensive software; in the surveying sector we use it create building and topographical surveys as well as a range of other uses. We can provide you with CAD and AutoCAD surveys to assist you on your project, providing you with a precise plan to work from.

What is a CAD plan?

A CAD plan uses computer aided design to produce a 2D or 3D illustration that can be used in the planning and development of an engineering or architectural project. It can be used throughout the process from initial design to construction work.

A CAD plan, particularly 3D, allows the user to view the image from different angles and be able to accurately plan and design. Because of the computer design, it can be easily adapted and adjusted – making it more time efficient and accurate than manual drawings. This could allow an architect or construction company to experiment with different options to find a solution that will work best for the project. It also allows stakeholders to have more of a vision of how the final product will look and fit into the surrounding environment.
We can provide both digital, printed and 3D models of CAD plans to assist with your project.


Do surveyors use CAD?

Professionals across a range of industries use CAD software, but the tool is especially popular among designers, architects, construction engineers and surveyors who need to create precise, technical drawings. CAD allows surveyors to produce realistic representations of an existing structure.

What is a CAD survey?

A CAD survey is simply a measured building survey, which is produced using CAD (computer-aided design). Architects, construction engineers and surveyors use this software to put together a precise and exact image of all elements of a building, including all structural and architectural elements. CAD tools are commonly used for building surveys because they allow the user to view the image from all angles, and offer a cost-effective, time-efficient and highly accurate alternative to manual drawings.

Why is CAD important for measured building surveys?

A measured building survey needs to provide a precise and exact image of all the structural and architectural elements of a building. Therefore, it’s crucial that the latest technologies, such as CAD software, are used to analyse and collate the data needed to create that plan. CAD allows the user to capture all aspects of a building with the greatest detail and accuracy. It enables the user to view the image from any angle, as well as consider any impacts it might have on the environment.
