In recent years, the concept of BIM (Building Information Modeling) has become increasingly familiar in Vietnam’s construction industry. However, many people still confuse the levels of BIM such as 3D, 4D, and 5D. So, what are the differences between them? And why is BIM considered the “key” to modern construction?
CMC Architects will help you clarify each aspect — and reveal the promising future of BIM in Vietnam.
📌 What is BIM?
BIM is the process of creating and managing a building’s digital information throughout its design, construction, and operation phases. More than just a 3D model, BIM is a dynamic data system that supports accurate decision-making across the entire project lifecycle.
🧱 1. BIM 3D – The stage of form and spatial visualization
👉 Description:
BIM 3D is the foundational stage, used to visually simulate the shape, dimensions, and relationships between components of a building (architecture, structure, and MEP systems).
✅ Benefits:
-
Clear design visualization
-
Minimizes errors in interdisciplinary coordination
-
Easily conveys design intent to investors and review boards
📍 Applications:
-
Presenting design concepts
-
Creating persuasive 3D visualizations
-
Used during concept, preliminary, and technical design stages
⏳ 2. BIM 4D – Integrating construction time into the model
👉 Description:
BIM 4D integrates the time factor into the 3D model. Each construction stage is linked to a specific part of the model, allowing simulation of the building sequence according to the schedule.
✅ Benefits:
-
Create visual construction schedules
-
Detect construction conflicts early
-
Reduce delays and improve coordination efficiency
📍 Applications:
-
Construction planning
-
Managing large-scale construction projects
-
Communicating project schedules clearly to investors
💰 3. BIM 5D – Integrating cost factors into the model
👉 Description:
BIM 5D integrates cost estimation and budgeting information into the model. Any change in the design directly impacts the project’s costs, enabling real-time budget updates.
✅ Benefits:
-
Tight cost control from the start
-
Optimize budgets based on design scenarios
-
Ensure financial transparency throughout the project lifecycle
📍 Applications:
-
Efficient investment planning
-
Minimize unexpected cost overruns
-
Provide clear financial data to managers and investors
🚀 The Future of BIM in Vietnam – Time to take action today
📊 Current reality:
-
BIM is still mainly applied at the 3D level in most companies
-
Integration of 4D and 5D remains limited due to lack of data infrastructure and skilled personnel
-
Some large corporations have already begun a strong transition
🧭 Forecast:
-
From 2025, many industrial, infrastructure, and urban projects will be required to implement BIM.
-
Government agencies are expected to soon require BIM models as part of bidding documents.
-
Enterprises applying BIM comprehensively will gain a clear advantage in bidding, management, and operation.
