The BIM explained

WHAT IS BIMThe BIM explained

Depending on the source, there are different definitions of the BIM or Building Information Modelling.

For the National Building Specification organization in the UK, BIM " a process for creating and managing information on a construction project across the project lifecycle." In other terms, it is condered a process for designing a building through a model using smart parametric objects (such as slabs, walls, roofs, etc.) that emulate the physical characteristics of their real-life counterpart, then injecting vital information that can be used in the different stages of the building lifecycle.

BuildingSMART looks at the BIM as a product. BIM is " a digital representation of physical and functional characteristics of a facility. A building information model is a shared knowledge resource for information about a facility". 

CADcentre consider those definitions as the two sides of the same coin and we tend to concentrate at the advantage that working in BIM can procure, no matter the scale of the project getting produces or the size of the team working on it. The adoption of BIM has changed the process of how many architects and designers work. It improves on the design process, reduces the coordination time, and elevates the quality of the deliverables.

Cadcentre will guide you in you the process of migrating from the traditional CAD to BIM, helping you in shortening the learning curve.

Why is BIM needed.

We inherited the CAD process from the times of the drafting table.  It’s a process that was built upon the false pretence that a project progresses in a smooth linear fashion, from concept to tender. But the design process is far more complex but it never happens this way. We always need to go back into our documents and do modifications.

Thus, the CAD process becomes fragmented. We tend to waste time doing changes and coordinating the projects drawings. Modifications required throughout the design process can also lead to mistakes...



The BIM advantages:

The single model is a single source of information:

While the CAD process is about the preparation of documents, the BIM revolves around designing the building. The software should translate the modelled building to documents. At any phase of the design, we have ONE source (the model) from which all the documents get extracted.

Up to date all the time:

Modifications and revision are implemented directly on the model; the drawings follow, leaving less room for error. The designers are freed up to spend more time on the creative process.

While we are concentrating on the design, plans, sections, and elevations get generated by the software. The BIM process is automated. This removes much of the redundant work related to conventional drafting.

Faster CD phase:

The construction documents (CD) phase, is where the majority of an architect’s time is historically spent. Not anymore with BIM. The transition from schematic design to design development is smooth. The work done in the schematic phase is the basis of the CD phase.

Both sets of documents are different reflections of the same database. No need to ‘save as’ the project file and rework all the documents.

The EFFORT Curve

HOK Chairman Emeritus Patrick MacLeamy, FAIA developped the curve illustrated above to explain the problems encountered by the Architects still developping their projects in CAD, and the impact on design of switching to BIM. 

Better Collaboration:

Members of the same firm and other consultants can work on the same model at the same time. It can also be shared and its data harnessed throughout the project’s lifecycle.

A hub for the new technologies:

The technology for designing buildings is moving fast. Design validation of client’s requirement, Algorithmic design, clash detection, code validation, etc are all tools available to use with the BIM model.

The specificity of BIM for Architects & Designers

At Cadcentre, we looked for the right tool that gets our customers the best workflow. To answer that, we looked at a more fundamental question: what is the role of the Architects and Designers. Is it the mere preparation of document for any project or giving a high level of design to its customer?
Can a software contribute in bringing the focus back into the design exploration, while remaining a full BIM solution? Most of the firms that are using Revit are still using software like Sketchup and Rhino for the design phase, the tools and modelling techniques within Revit are not optimized for the design process.

That led us to promote ArchiCAD. A software that was originally designed by Architects for the Architect. ArchiCAD is continuously developing innovative features for the needs of the Architect, the Designer, and the Design-build contractor. It’s a complete building information solution that will answer all the requirement of these professionals from the first sketch to the finalization of the project.

Avoiding the complexity and focusing on gain in productivity 

BIM doesn’t need to be a big and complex endeavour. The process should be modelled to your need. It’s a tool to gain productivity, while improving the quality of the design. If you want guidance on the road to follow and what would be the best tool, specific to the Architect and the Designer, please contact us and let’s start the conversation.
