Building Information Modelling – BIM Surveys

At Castle Surveys Ltd, we know how important the use of BIM (Building Information Modelling) can be to design, surveying, and construction industries.

With today’s technology, we can assist industries with intelligent 3D plans that provide an accurate depiction of a building, site plan, or plot of land using BIM technology.

Moreover, 2D plans can be extracted from the 3D design to ensure consistency and reliability in data throughout a project’s life-cycle.

We know that if all phases of the BIM are constructed correctly, those plans can save you precious money and time on a building project.

What is a BIM Survey?

Building Information Modelling (BIM) is an intelligent 3D modelling technology.

BIM’s purpose is to ensure that vital information is collected and created at the right time to make better decisions throughout a building project’s lifecycle.

This 3D model-based process is an enabler, allowing for the collaboration of professional architects, engineers, and construction managers.

BIM gives its users deeper insight into their projects and the tools needed to more effectively and efficiently plan and manage the design, construction, and infrastructure of their projects.

Castle Surveys Ltd.’s vast experience in utilising 3D Laser Scanning technology means our workflow processes and technological enhancements can provide detailed and accurate BIM Models.

From the inception of your project to fruition, our clients and their employees have the time they need to focus on other aspects than modelling with 2D data.

What is BIM’s Level of Development (LOD)?

“The devil’s in the details”; at Castle Surveys Ltd, we take great care of the details.

The LOD is a powerful tool for collaboration and refers to the Level of Development or Level of Detail (either will suffice).

The LOD is a set of specifications defining the development of different systems in BIM. See below for our breakdown of LOD.

LOD 100 (Conceptual)

The initial stages of modelling may be graphically represented in the 3D model with a symbol or other generic representation.

This stage does not satisfy the requirements for LOD 200, where other information can be related to the model element.

LOD 200 (Generic Placeholders)

Now the model element is graphically represented within the model as a generic system, object, or assembly.

Approximate quantities, size, shape, location, and orientation are now known and non-graphic information can be attached.

LOD 300 (Specific Assemblies)

This is where things start to get more accurate; the 3D model element is now graphically represented within a specific system, object, or assembly, which is also accurate in terms of quantity, size, shape, location, and orientation.

LOD 400 (Detailed Assemblies)

At this stage the model is graphically represented as a specific system, object, or assembly that is now on point in terms of size, shape, location, quantity, and orientation, with detailing, fabrication, assembly, and installation information.

LOD 500 (As Built)

The model element is now a field-verified representation in terms of size, shape, location, quantity, and orientation.

Please note, from LOD 200, all non-graphic information may also be attached to the 3D model elements.

Why choose Castle Surveys Ltd for your BIM Surveys?

Building Information Modelling continues to revolutionise how we work, from architecture and engineering to building sites and the development of unique complexes. Industries are working together to communicate, solve problems, and build better projects.

At Castle Surveys Ltd, we believe our collaborative approach and 3D laser scanning expertise has allowed us to develop a process which delivers fast, accurate survey information in a BIM 3D model every time.
