Goal
Design and implement a smart city integration framework for One Bangkok, unifying more than 30 operational technology and IoT systems into a secure, vendor-neutral platform for Southeast Asia's largest urban development.
Areas covered
Smart city strategy, PMO governance, systems architecture and integration, vendor evaluation and procurement, data governance, cybersecurity implementation, and operational handover.
Outcomes
Delivered and operationalised a central integration platform connecting more than 30 operational technology and IoT systems, enabling unified data management, real-time monitoring, and district-wide interoperability.
Insight Gained
At scale, the architecture is the governance. Committing to a vendor-neutral integration layer before procurement begins eliminates the most persistent source of long-term lock-in — and is far harder to retrofit than to design in from the start.
It holds LEED Platinum certification for neighbourhood development and, at the time of its opening in October 2024, was the largest mixed-use urban development under construction in Southeast Asia. Across the site, more than 250,000 IoT sensors are embedded into the built environment.
The ambition extended beyond construction. One Bangkok’s developers sought to integrate smart services across energy, water, telecommunications, predictive maintenance, video analytics, security, traffic, and parking — creating an operational ecosystem as complex as the physical infrastructure it runs alongside.
TCC Technology — the smart services subsidiary of TCC Group, the project’s developer — engaged ddx to design and deliver the integration framework that would make this possible.
The platform needed to serve One Bangkok’s command centre as a single operational nerve centre — providing unified visibility across energy, water, security, mobility, and building management, while remaining adaptable as the district’s smart services continued to evolve post-launch.
Underpinning this was a set of non-negotiable requirements: compliance with local Thai data privacy regulations and international standards, robust cybersecurity architecture, and a governance model capable of managing delivery across a large, multinational vendor ecosystem. The solution also needed to be fully transferable — designed so that One Bangkok’s internal team could operate it independently from day one.
Building on earlier involvement alongside Hitachi Asia, ddx assumed full responsibility for smart services delivery and systems integration in 2023, providing technical leadership and programme governance through to opening.
Starting from an existing high-level architecture, ddx expanded the solution definition to establish clear integration standards, data models, and governance structures across the estate. A central, vendor-neutral integration platform was designed and implemented to connect more than 30 operational technology and IoT systems — including energy, water, security, mobility, and building management — through secure, API-based interfaces.
ddx led the technical evaluation and procurement of specialist vendors on behalf of TCC Technology, managing awarded work packages through the smart city PMO and coordinating delivery across a complex, multinational stakeholder environment. Throughout, ddx embedded cybersecurity controls, data privacy safeguards, and compliance mechanisms aligned with both local and international regulations.
The approach prioritised scalability, interoperability, and operational readiness — ensuring the platform could be confidently handed over to One Bangkok’s internal command centre team while remaining adaptable to future system expansion.

The platform’s vendor-neutral architecture meant no single supplier held a position of dependency, and the system was designed from the outset to accommodate future services and expansion. Cybersecurity controls and data privacy compliance were embedded throughout, meeting both local Thai regulatory requirements and international standards.
The project’s smart city credentials were independently recognised: One Bangkok received WiredScore and SmartScore Platinum certifications at launch — reflecting the quality of both the digital infrastructure and its integration.
Managing a large and diverse vendor ecosystem introduced further complexity. Different technologies, protocols, and multilingual stakeholder groups required structured governance and disciplined communication to keep the programme coherent.
ddx addressed this through prioritised integration sequencing — identifying the most critical and interdependent systems first before expanding across the wider estate. Each integration required detailed protocol analysis and rigorous validation to ensure compatibility with the central platform, while maintaining compliance with data privacy and cybersecurity requirements throughout.
