Service Overview
Designing a semiconductor fab is one of the most complex engineering challenges in the built environment. Cleanroom architecture, vibration-sensitive structural systems, ultra-pure utilities, and high-density electrical infrastructure must all operate seamlessly within extremely constrained spaces.
Desapex delivers a fully coordinated, digitally driven design approach, where every discipline is integrated into a single federated BIM environment. This ensures that cleanroom performance, process utility efficiency, and spatial coordination are achieved simultaneously eliminating conflicts before construction begins.
Our Digital-First Approach
Federated BIM Coordination
All disciplines architectural, structural, HVAC, process utilities, and electrical are integrated into a single intelligent model.
Core Deliverables
Cleanroom Architectural Design (ISO Class 1–7)
Raised floor/waffle slab systems, FFU ceiling integration, and chemical-resistant finishes.Vibration-Isolated Structural Systems
Isolated tool pedestals, tuned mass dampers, and foundations designed to meet VC-D to VC-G criteria.Advanced HVAC & Cleanroom Air Systems
Make-up air units, recirculation systems, FFU arrays, pressure cascades, and precision environmental control (±0.1°C, ±1% RH).Ultra-Pure Water (UPW) Systems

Acid, solvent, heat, and toxic exhaust systems with integrated scrubber and abatement technologies.Electrical Power Distribution Infrastructure
HV substations, MV switchgear, UPS systems, PDUs, and clean grounding for critical operations.
Why Choose Desapex
In semiconductor facilities, the subfab and utility corridors are as critical as the cleanroom itself. Even a minor coordination error such as a routing conflict or maintenance access issue can result in costly redesigns and construction delays.
Desapex ensures continuous, real-time coordination across all systems, resolving conflicts during the design phase when changes are fast and cost-effective. This approach minimizes risk, accelerates project timelines, and ensures that the facility performs exactly as intended from day one.
Unique Selling Proposition
Desapex’s BIM models go beyond geometry they embed semiconductor-specific performance intelligence.
By integrating parameters such as vibration criteria, cleanroom classifications, pressure relationships, and per-tool utility allocation, the model becomes a true digital representation of facility performance not just a coordination tool. This enables precise engineering decisions and ensures the facility meets the exacting standards of semiconductor manufacturing.
