STT Bangkok 01

STT Bangkok 01 Delivering Precision Floor Systems for a Global Hyperscale Data Centre Project Overview STT Bangkok 01 is the flagship facility within the STT Bangkok Data Centre Campus, developed by ST Telemedia Global Data Centres (STT GDC), one of the world's leading data centre operators. Strategically located in Hua Mak, Bangkok, the seven-storey hyperscale facility provides up to 23 MW of IT capacity and forms part of one of Thailand's largest carrier-neutral data centre campuses built to international standards. VCON supplied prestressed hollow core slabs for the project, contributing to the construction of a high-performance floor system designed to support the operational requirements of a mission-critical digital infrastructure facility. Manufactured under strict factory-controlled conditions, the hollow core slabs provided consistent quality, efficient installation, and an optimized structural solution for one of Thailand's most significant hyperscale developments. The Challenge As a hyperscale data centre developed to international standards, STT Bangkok 01 demanded a structural floor system capable of meeting stringent requirements for quality, reliability, and construction precision. The floor system needed to support heavy operational loads while accommodating numerous slab penetrations for electrical distribution, cable trays, mechanical services, and future technology upgrades. Close coordination between the structural and MEP disciplines was essential to avoid construction delays and ensure efficient installation of mission-critical infrastructure. The project was also executed during a period of significant volatility in construction material and energy costs. Rising oil prices increased the cost of concrete production, transportation, and site operations, placing greater importance on structural solutions that optimized material usage, reduced overall building weight, and lowered embodied carbon without compromising structural performance. The Structural Solution VCON supplied prestressed hollow core slabs specifically engineered for the demanding requirements of hyperscale data centre construction. The hollow core slab system provided long-span floor construction while reducing the volume of concrete required compared with conventional solid slabs. This material-efficient design reduced the overall dead load of the structure, contributing to lower embodied carbon, reduced transportation requirements, and improved cost efficiency during a period of fluctuating material prices. Each slab was coordinated with the project's structural and MEP requirements to accommodate numerous service penetrations for electrical distribution, cable trays, piping, and other mission-critical building services. Manufacturing in a controlled factory environment ensured consistent dimensional accuracy, allowing efficient installation and minimizing on-site adjustments during construction. Project Impact Although VCON's scope focused on the floor system, its contribution supported the delivery of a facility designed to meet the rigorous standards expected of a global hyperscale data centre operator. The project demonstrates how precision-manufactured hollow core slabs can contribute to the efficient construction of mission-critical facilities where quality, coordination, and long-term operational reliability are essential. Key Outcomes High-quality prestressed hollow core floor system manufactured under factory-controlled conditions Optimized concrete consumption through a lightweight structural design Reduced overall structural dead load Accommodation of complex MEP service coordination Consistent dimensional accuracy for efficient installation Reduced embodied carbon through material-efficient construction Reliable structural solution supporting international project standards Why It Matters For global data centre operators, construction quality is measured not only by speed but by consistency, precision, and long-term reliability. Factory-manufactured prestressed hollow core slabs provide a repeatable, high-quality floor system that supports complex building services while reducing material consumption and structural weight. For owners developing mission-critical facilities, these advantages improve construction certainty and contribute to more sustainable, efficient, and reliable project delivery.
