BIM Explained: What Lies Behind It?

BIM is not a programme – it is a method. We explain all seven dimensions from 1D to 7D, why BIM is far more than software, and how it fundamentally changes your practice.

BIM Explained: What Lies Behind It?

1D

Idea & Brief

The first dimension describes the building as an abstract list of requirements: spatial needs, functional relationships and use concepts. This is where the brief is formed – the document that drives all subsequent dimensions.

2D

Drawing & Floor Plan

Traditional two-dimensional design: floor plans, sections and elevations. BIM transforms these drawings into intelligent, parametric objects – every change automatically updates all linked views.

3D

Geometry & Visualisation

The digital building model as a three-dimensional representation of all components and their spatial relationships.

4D

Time & Construction Phases

Integration of the construction programme into the model – simulation of construction phases and scheduling in real time.

5D

Costs & Calculation

Automatic quantity take-off and cost calculation directly from the model – fewer errors, greater transparency.

6D

Sustainability & Energy

Energy simulation, carbon footprint and sustainability certification as an integrated part of the design process.

7D

Facilities Management

The BIM model as a digital twin for the entire lifecycle of the building – from design through to demolition.

The Verdict

Our Assessment

BIM is not a programme you purchase – it is a method that transforms your practice and improves project quality.

Those who master BIM today lay the foundation for AI tomorrow – AI requires clean data that only BIM can provide.

The seven dimensions of BIM save time, money and effort when applied consistently in everyday project work.

Getting started is easier than you might think – with the right partner, the transition happens step by step.

BIM is no longer a competitive advantage – it is becoming a prerequisite. Public clients demand it, contractors expect it, and clients value the transparency it brings.
