If you work in construction and are not yet using BIM, you probably will need to soon. Governments around the world are introducing mandatory use of Building Information Modeling for public construction projects, and the trend is rapidly extending to the private sector as well. The question is no longer whether BIM will become the standard — but when it will become mandatory for your segment.

What Is BIM?

Building Information Modeling (BIM) is a process based on a digital 3D model that contains not only the geometry of the building but also information about every element — material, manufacturer, cost, maintenance requirements, service life. BIM is not just a "3D drawing" — it is an intelligent information model that serves as a single source of truth for the entire lifecycle of the building.

Unlike traditional 2D design, a BIM model enables:

Automatic clash detection — for example, a pipe running through a structural element
Precise quantity extraction — automatic generation of quantity surveys from the model
Multi-discipline coordination — architecture, structural, and MEP teams work within one model
Visualization and simulation — the client sees the end result before ground is broken
Full lifecycle management — from design through construction to operation

BIM Maturity Levels

BIM is not an "on/off" switch — there are different maturity levels that define the depth of implementation:

Level 0 — No BIM

Working with 2D drawings on paper or in PDF format. No digital modeling, no data coordination. Still the dominant approach among small and mid-sized firms.

Level 1 — Partial BIM

Use of 3D modeling for visualization, but without full coordination between participants. Each discipline works in its own model, without integration. Data exchange is still primarily through 2D drawings.

Level 2 — Coordinated BIM

Each discipline creates its own 3D model, but models are coordinated through a Common Data Environment. Clash detection is standard practice. Information is structured and accessible to all participants. This is the level most government mandates require.

Level 3 — Integrated BIM

A single, shared model in which all participants work simultaneously. Full real-time data integration. Still more of a vision than a widespread practice, but the technologies to achieve it already exist.

Global Trends in BIM Mandates

Accelerating Adoption

In recent years, a clear global trend has emerged: more and more governments are mandating BIM for public procurement. The motivation is clear — public projects executed with BIM show, on average:

20-30% reduction in errors during design and construction
10-15% cost savings through earlier identification of conflicts
Better asset management after construction is complete
Greater transparency in the use of public funds

Expanding Scope

Initially, BIM mandates covered only large public infrastructure projects. Gradually, the scope is expanding:

By value — thresholds for mandatory BIM are continually decreasing
By project type — from infrastructure to residential and industrial construction
By phase — from design to construction and operation
To the private sector — large investors and financing institutions increasingly require BIM

openBIM and Standardization

A critical element of global BIM adoption is the movement toward openBIM — open standards that allow data exchange between different software platforms. The key format is IFC (Industry Foundation Classes), an ISO standard for construction information exchange.

The significance of IFC is enormous: it allows the various participants in a project to work with the software of their choice, without being locked into a single vendor's ecosystem. For more information about the IFC format and how it integrates with construction management software, see our article on IFC and BIM import.

What Does This Mean for Construction Firms?

Preparation Is Needed Now

Even if BIM is not yet mandatory for your specific segment, preparation should begin before the mandate takes effect. The transition to BIM requires:

Investment in training — the team needs to acquire new skills
New software and hardware — BIM modeling is more resource-intensive
Process changes — the way work is done changes fundamentally
A new culture of collaboration — BIM demands closer coordination between participants

Firms that prepare in advance have a significant competitive advantage — they can participate in larger and more complex projects that require BIM.

BIM Is Not Just for Designers

A common misconception is that BIM is only the responsibility of designers. In reality, construction firms are increasingly involved in the BIM process:

4D BIM — adding a time dimension (schedule) to the model
5D BIM — adding a cost dimension (budget) to the model
Digital construction tracking — comparing actual execution against the model
As-built model — updating the model with real-world parameters after construction

The Link Between BIM and Project Management Software

The BIM model generates a vast amount of structured data — quantities, materials, timelines. This data becomes truly valuable when integrated with construction project management software:

Quantity surveys from the BIM model can automatically feed the budget control system
The schedule from a 4D model can be synchronized with operational planning
Changes in the model can automatically generate change orders and budget updates

This integration is the direction the industry is heading — and digitizing your construction company is the prerequisite for it.

How to Get Started

If you have not yet started with BIM, here are practical steps:

Assess your current level — where do you stand on the scale from Level 0 to Level 3?
Define the goal — for most firms, Level 2 is the realistic medium-term target
Invest in training — start with the key people on your team
Choose a pilot project — do not try to transition to BIM all at once
Integrate BIM with your other systems — project management, finance, warehouse management

BIM mandates are not a threat — they are an opportunity for firms that are ready. And as with every change in construction, sooner is better than later.
