Case Study
Advanced BIM Implementation & Digital Twin Strategy
Leveraging BIM for precision, predictability, and long-term asset value
Executive Summary
Chenla Agathos delivered an advanced BIM and Digital Twin framework for a large-scale convention and office complex, enabling precise coordination across architecture, structure, and MEP systems. The approach reduced construction risk, improved cost predictability, and produced a verified digital asset ready for long-term operation.
Project Snapshot
- Client
- Dhanarak Asset Development Co., Ltd.
- Location
- Bangkok, Thailand
- Site Area
- Over 600,000 sqm
- Contract Value
- Over USD 570 million
- Duration
- 30 months (design through construction documentation)

The Challenge
The context, constraints, and risks shaping the project from the start.
The project combined highly complex curved architectural geometry with dense MEP systems and an aggressive delivery schedule. Coordinating multiple disciplines within constrained ceiling spaces created a high risk of clashes, rework, and cost overruns.
Complexity
- Non-standard curved façade and structural geometry
- High-density MEP networks within limited vertical clearances
- Tight 30-month program with limited tolerance for rework
- Large stakeholder group requiring consistent, reliable information
What Was at Stake
Without early coordination and reliable quantity data, the project faced a significant risk of schedule delays, cost overruns exceeding 10% of the MEP package, and downstream operational inefficiencies.
How Chenla Stepped In
The targeted actions we took to resolve the core issues.
Chenla designed and enforced a structured BIM management framework, positioning the federated model as the single source of truth throughout design coordination and documentation.
Key Actions
- Established an ISO 19650–aligned BIM Execution Plan (BEP)
- Defined LOD, naming, and classification standards across all disciplines
- Led weekly coordination and clash-resolution cycles
- Integrated model-based quantity take-offs for real-time cost tracking
- Prepared structured Digital Twin data for operational handover
Solution Highlights
What Chenla delivered to address the project's challenges.
Federated Coordination Model
Architecture, structure, and MEP systems were integrated into a single coordinated environment to eliminate conflicts early.
5D Cost Integration
Model elements were directly linked to quantity and cost data, enabling instant budget updates when designs changed.
Construction-Ready Outputs
Shop drawings and coordinated documentation were generated directly from the validated BIM model.
Digital Twin Handover
The verified as-built model was structured for facility management, future retrofits, and lifecycle analysis.
Outcomes
What changed for the client as a direct result of our intervention.
Operational Results
- Resolved over 500 critical clashes digitally before construction
- Reduced quantity take-off variance to below 4%
- Cut RFI volume by approximately 35%
- Saved an estimated 6 weeks in MEP installation through 4D sequencing
Client Benefits
- Lower construction risk and fewer site disruptions
- Improved cost predictability and procurement confidence
- Shortened installation timelines
- A verified Digital Twin asset usable beyond handover
