3D modelling is a process by which construction professionals are able to design and plan a building project using computer aided design software. It is becoming increasingly more sophisticated and people are relying on it more than ever within their construction work. It has been described as a revolutionary process that has completely changed the face of construction, allowing it to be efficient, safe, cost effective and environmentally friendly.

The process of using data to produce a 3D model is known as BIM – building information modelling. It is very useful for architects and designers as it can produce such detailed and lifelike results. It can be used to replicate buildings of all kinds, or even to replicate multiple buildings as was seen at a recent construction expo where a 3D digital model of London was showcased.

BIM has become so useful to us because of the way in which it allows us to understand a building. It can simulate anything from doors and windows to the systems that will be used within the building, giving people a thorough understanding of how a building will operate.

Modelling has some very obvious benefits in terms of health and safety. The deep level of understanding it can give us is especially useful in the early stages of planning a building, as architects can ensure that their solutions are practical, realistic and safe. If any obstacles present themselves, BIM can be used to help overcome them safely. This can help to cut costs as well – issues should be far more readily apparent than they used to be, meaning that construction professionals won’t need to spend extra money fixing them. This is something that has been very much welcomed by the health and safety and construction industries alike. It makes the construction process and the actual use of the completed building much safer for everyone involved.

Innovations in modelling and CAD also have many ramifications for the energy efficiency of a completed building. By using these kinds of technologies, defects can be reduced, making it easier to construct buildings that will stand the test of time and use energy efficiently. Data can also be calculated to help the people who will occupy the building use it in the best way they can.

Whilst it is very useful when putting a building up, CAD design can also inform the way a building is taken down. It can allow construction professionals to asses how to dismantle a building to have minimal impact on the environment, and will ensure that materials are either reusable or suitable for recycling.
