In modern construction, BIM (Building Information Modeling) is redefining how interior projects are designed and executed. More than just a 3D model, BIM is an integrated information management process that connects data from design and production to operation.

At TTT Corporation, BIM has been applied to numerous high-end hotel, office, and resort projects, delivering exceptional precision, well-controlled schedules, and superior quality.

What Is BIM?

BIM is a digital model that simulates an entire building. Each element in the model contains detailed information about materials, costs, timelines, and maintenance.

Common BIM dimensions include:

• 3D – Visualizing geometry, structure, and interior details.

• 4D – Integrating time factors to create construction schedules.

• 5D – Managing costs and materials in real time.

• 6D – Analyzing energy efficiency and sustainable materials.

• 7D – Supporting maintenance and operation after handover.

Benefits of BIM in Interior Construction

1. Fewer Errors, Greater Precision
BIM identifies clashes between architectural, MEP, and interior systems during the design stage, preventing costly errors on-site.

2. Effective Cost Management
With 5D BIM, material quantities and costs are automatically calculated and updated, ensuring accurate budgeting and optimized resource allocation.

3. Shorter Construction Time
4D BIM simulates construction sequences, allowing teams to plan manpower and equipment efficiently while minimizing overlapping tasks.

4. Transparent Collaboration
All stakeholders work within a shared digital environment where every update is synchronized, ensuring consistency and reducing misunderstandings.

5. Improved Quality and Sustainability
6D BIM supports energy analysis, sustainable material selection, and green design optimization—aligning with today’s focus on sustainable interiors.

6. Better Client Experience
3D and VR models allow investors to visualize the finished space in advance, making it easier to adjust designs before construction begins.

BIM Implementation Process at TTT Corporation

With over 30 years of experience, TTT Corporation has developed a BIM workflow that meets international standards, integrating seamlessly from design to handover.

1. Design Phase (BIM 3D)

• Gather data and requirements from clients (EIR).

• Build detailed 3D models of spaces, furniture, and MEP systems.

• Develop a BIM material library for consistent and efficient project delivery.

2. Pre-Construction Phase (4D & 5D)

• Detect potential clashes between systems before construction.

• Create 4D construction schedules and 5D cost estimates that update automatically.

3. Construction Phase

• TTT engineers access BIM models directly on-site for installation guidance.

• Progress and quality are monitored in real time to ensure on-schedule delivery.

• Any changes are updated immediately within the shared model.

4. Handover & Operation (6D & 7D)

• Deliver As-Built BIM models containing all material, equipment, and maintenance data.

• Support facility management with easy access to maintenance schedules and cost optimization over the building’s lifecycle.

Challenges & Solutions in BIM Implementation

Common Challenges:

• Initial investment in software, hardware, and staff training.

• Shortage of skilled BIM professionals in the interior industry.

• Shifts in workflow requiring stronger cross-team coordination.

TTT Corporation’s Solutions:

• Phased investment, prioritizing large-scale projects first.

• Continuous internal training to build a skilled BIM engineering team.

• Standardized BEP (BIM Execution Plan) ensuring coordination between design, production, and construction.

• Compliance with IFC international standards for smooth data exchange between platforms.

BIM Software Used by TTT Corporation

• Autodesk Revit – Comprehensive BIM tool for architecture, MEP, and interiors.

• Navisworks – For model integration, clash detection, and 4D simulation.

• ArchiCAD & Allplan – Strong tools for interior design and material management.

• SketchUp (BIM plugins) – Ideal for concept development and quick visualization.

By combining these platforms, TTT Corporation ensures precision, efficiency, and seamless coordination across all project stages.

Frequently Asked Questions

Is BIM necessary for all interior projects?
For complex projects like hotels, resorts, and large offices—where precision and deadlines are critical—BIM is nearly indispensable.

How is BIM different from CAD?
While CAD creates 2D drawings or basic 3D models, BIM integrates material, cost, timeline, and operation data, enabling full lifecycle management of a project.

Does BIM help reduce costs?
Yes. With accurate 5D cost estimation and minimized rework, BIM significantly reduces material and labor expenses.

Which projects has TTT applied BIM to?
BIM has been implemented in large-scale projects such as Fairmont Hanoi, Pullman, Novotel, and various luxury resorts, all requiring high technical precision and synchronization.

BIM is no longer a trend—it’s the new standard in modern interior construction.
By centralizing project data, BIM minimizes risks, controls costs, and enhances construction quality.

With a commitment to sustainable development, TTT Corporation continues to pioneer BIM adoption to craft refined, efficient, and enduring interior spaces—affirming its position as one of Vietnam’s leading interior contractors.
