In a construction project, the preliminary design phase is often overlooked. Many investors and contractors only focus on beautiful perspective drawings, total budget and progress, without investing properly in building information modeling (BIM) from the very first step.
But in reality:
The preliminary design phase is the "golden" time to apply BIM - a tool that helps reduce risks, optimize costs and create a solid foundation for the entire life cycle of the project.
So why should BIM be introduced early? What can BIM do when the project is still… on paper? And does it really save time and money?
Let’s explore with CMC Architects!
📌 1. Detect technical conflicts early before entering detailed design
In the preliminary stage, architectural, structural, MEP (electrical, plumbing, ventilation, etc.) drawings are often independent. This can easily lead to technical conflicts that are only discovered during detailed design – or worse, during construction.
🎯 BIM allows:
3D simulation of the entire system from the beginning
Automatic collision detection between disciplines
Optimize design options before pouring a drop of concrete
👉 Results: reduce future error correction costs – save construction time – ensure project progress
📊 2. Make a more accurate preliminary estimate, better control the budget
One of the reasons why the budget "goes over the line" is due to inaccurate estimates in the early stages. When using BIM, the model will automatically calculate the volume of materials, the number of equipment, the finished area...
📌 BIM helps:
- Create a bill of quantities (BOQ) automatically from a 3D model
- Increase the accuracy of bidding documents
- Compare design options by cost
💡 This is the basis for investors to make informed decisions, instead of depending on emotions or personal experience.
🧱 3. Optimize the design right from the "concept" stage
Instead of just having 2D floor plans and static perspectives, the BIM model helps stakeholders “enter” the project very early.
✅ From there, they can immediately evaluate:
- Is the internal traffic flow reasonable?
- Is the clearance height guaranteed?
- Is the usable space comfortable and airy?
🎯 These are extremely important in factories, warehouses, showrooms, and offices – where functionality always goes hand in hand with operational efficiency.
⚙️ 4. Increase the ability to review documents, finalize designs faster
The larger the project, the more stakeholders there are. Investors, architects, structural engineers, mechanical and electrical units, contractors... each party needs to "see" the project clearly from their own perspective.
With BIM, you can:
- Present vivid models instead of dry drawings
- Create 3D presentations, fly-through videos, or VR 360
- Help non-professionals understand and decide more easily
👉 Save weeks waiting for meetings – shorten the time to finalize plans – increase cooperation efficiency.
🏗️ 5. Create a consistent platform throughout the project life cycle
Applying BIM from the preliminary design stage is the first step to building a comprehensive management ecosystem, including:
- Technical design
- Bidding documents preparation
- Construction management
- Progress and cost control
- Maintenance and operation after handover
🎯 Once you start right from the beginning – you are giving yourself an advantage all the way through.
