3D modelling/BIM

At South West Surveys, we offer a full in-house 3D modelling/BIM service. Models can be produced from 3D point clouds, 2D drawings can be supplied by customers or we can visit your site and deliver a full service from the initial site survey right through to the final 3D model. Any building can be modelled, from the simplest of dwellings, to complex historical buildings, our services are unlimited.

3D models have a variety of uses; they make fantastic marketing tools for developers and help local authorities visualise future developments. 3D models also help architects view their latest creations in a real-world environment.

BIM (building information model) is gradually becoming increasingly popular. This is especially prevalent within government projects due to the recent advances in legislation which have led to a significant rise in the number of 3D models needed, making our BIM models a great resource for other professional parties to take forward.

LOD 1 – Massing Model

An LOD 1 Massing Model includes only the 3D shape “mass” of structures and main landscape surfaces, paths, kerbs, roads etc. The model is without structural features such as window and door openings. Massing models are mainly used for volumetric assessment or as a general backdrop for new build design and planning applications.

LOD 2 – Structural Model

Progressing on from LOD 1, an LOD 2 Structural Model includes main structural features such as window and door openings, internal walls, floors, ceilings, columns, beams, staircases, steps, chimneys and roofs. The model is without architectural features such as window and door frames, internal joinery, fitted furniture etc. Structural models are used for many purposes, such as rights of light studies, major extension, refurbishment and re-modelling schemes.

LOD 3 – Architectural Model

LOD 3 Architectural Models contain all architectural features that you would expect from the accurate 3D representation of an existing building or landscape.

The External Features of LOD 3 Models:

  • Masonry features
  • Door and window frames
  • Rainwater systems
  • Roofs and chimneys

These are all carefully detailed to suit your specific preference.

The Internal Features of LOD 3 Models:

Internally, the building structure is completed with:

  • Architraves
  • Skirting
  • Panelling
  • Cornice
  • Fitted furniture
  • Sanitary fittings

The model is without MEP features such as plant, service runs, ducting, electrical and lighting layouts, plumbing and radiators etc. Architectural Models are one of our most specified service and are especially beneficial with heritage buildings full of period details.

LOD 4 – High Specification Model

An LOD 4 High Specification Model includes MEP services which effectively complete the build. Externally, main plant will be added at roof and, or ground levels, along with wall mounted satellite, lighting and security systems. Internally plant, service runs, ducting, electrical and lighting layout, plumbing, radiators can all be specified. It’s important to note that we can only include exposed features that are clearly visible within the Point Cloud data.

BIM4I (BIM for infrastructure)

Using terrestrial 3D laser scanning and mobile lidar systems to rapidly survey highways, rail infrastructures, bridge, tunnels and other Civil projects. From the scan data, we can then create highly accurate Revit Building Information Models (BIM).

Engineering Models

Using terrestrial 3D laser scanning and mobile lidar systems Engineering models can be produce, such as water treatment plants, pump houses, oil & gas installations and other industrial facilities.

What does BIM stand for?

BIM stands for Building Information Modelling; an intelligent 3D model-based process that gives professionals in the architecture, engineering and construction professions the insight and tools to be able to plan, design, construct and manage buildings and infrastructures. The process is supported by a number of different tools and technologies to create a digital representation of a physical building or structure, with all of the characteristics included!

BIM helps to support decision-making regarding building assets, especially in industries including water, refuse, electricity, gas, roads, railways and tunnels.

3D Modelling and BIM involves models being produced from 3D point clouds also known as scan to BIM. Alternatively, customers can supply us with 2D drawings, or we can visit a site and conduct a site survey to help create a final 3D model. We can model any building, from simple properties to complex historical buildings with intricate detailing and infrastructure.

This intelligent model-based process gives architecture, engineering and construction professionals an insight into how to efficiently plan, design, construct or even manage buildings and infrastructure.

There are many different benefits of using a 3D building model in the construction industry, including:

  • Project visualisation – A 3D model can help people to visualise a project. The models can be very realistic, helping the team involved to better understand the scope of the project.
  • Selling a project – A well designed model can be a crucial marketing piece to sell the project. Making sure everyone is working towards a common vision will ensure a smoother construction process.
  • Improving project speed – A 3D building model can help to save valuable time and money. The models can be shown to everyone involved and help to save significant time throughout the process.
  • Precision and control – 3D models collect data to help produce an accurate representation of an existing building or a new project. The realistic model will give control over precision so that no time is wasted.
