Get highly accurate surveys for your BIM project

We deliver measured laser surveys which provide an accurate 3D Building Information Model for architects and engineers to use as the foundation for their work.

Our expert surveyors will help you select the right BIM survey specifications and create 3D BIM models which ensure you have all the information you need to deliver your building project - on schedule, on budget and to specification.

Create accurate architectural models with our BIM surveys and 3D modelling support services

Our highly experienced team of 3D laser surveying experts will work with you to create a BIM survey specification which delivers the LOD (level of detail) your architects and engineers require.

You’ll also receive access to our 3D BIM model support services, including:

  •  3D design co-ordination
  • 3D model project management and clash detection reporting
  • Additional measurement such as an as-built verification survey

As well as architectural detailing, we also incorporate mechanical and electrical services information within the 3D BIM model, as well as adding topographic and underground utilities data.

 

“The model is very impressive and we can now be more confident with on-site works.”

 David Harrison, Design and Drawing Office Manager, Nusteel Structures

Discover our 5-specification levels for delivering your ideal BIM survey

Developed in line with the RIBA Digital Plan of Works, our specification has five defined levels to provide you with the ideal BIM survey.

Stage-by-stage we can provide an increasing LOD (level of detail) to deliver the information and intricacy of modelling you require for your BIM project:

Level 1 - LOD 1 - base survey mass model

This provides a basic 3D BIM model of buildings and structures at a 1:200 traditional scale – without any architectural details.

Surveys for BIM LOD 1
Surveys for BIM LOD 2

Level 2 - LOD 2 - structural components base survey model

This 3D BIM model includes major structural components and structural openings at a 1:200 traditional scale.

Level 3 - LOD 3 - standard survey model

This 3D BIM model includes basic principle architectural details and structures at 1:50 or 1:100 traditional scale. It is highly suitable for generating survey plans, elevations and sections.

We also build in basic families to a default setting, which can include main MEP (mechanical, electrical and plumbing) services or FF&E (furniture, fixtures and equipment) in outline form.

Surveys for BIM LOD 4

Level 4 - LOD 4 - detailed survey model

This 3D BIM model contains detailed architectural and structural features.
Families will be built to a higher level of detail and principle finishes and construction will be indicated where known.

The model is suitable for generating survey plans, elevations and sections at 1:50 or 1:20 traditional scale. The main and subsidiary MEP and FF&E elements can be included if required.

This level of 3D BIM model is often ideal for recording historic or listed buildings

Level 5 - LOD 5 - detailed survey model with metadata

This 3D BIM model is similar LOD 4 but enhanced with additional non-geometric/parametric data and record information supplied by you or a third party.

It represents the highest level of 3D BIM modelling available.

CADS point cloud and 3D laser surveys

Having CADS on board meant we were able to establish a high level of detail from the offset. Their depth of coordination during the 3D modelling process meant it wasn’t just the big architecture items that were addressed, but also the intricate details.

The standard of accuracy we required for the Bloomberg auditorium fit-out could not have been achieved without the good data that digital technology enabled us to capture.

Mark Hazell Project Manager, TMJ Interiors

3D design coordination for award-winning auditorium

Working with specialist joinery contractor TMJ Interiors, CADS coordinated the project designs of all 70 contractors to create a federated Revit® model

Revit® BIM integration

Once we have agreed on the BIM model’s level of detail (LOD), we also help accommodate either a Revit® families library or incorporate your preferred specification using a bespoke format which we create.

The time and cost required to capture data and create the model increases with the level of detail.

Flexible technical support

With our practical experience of digital construction, our professional team of surveyors provide much more than just highly accurate surveys, measurements and 3D models.

We can deliver knowledgeable support and project management which allows you to enjoy the much-celebrated benefits of BIM in reducing time, cost and waste.
