Service Overview
Semiconductor fab construction operates on highly compressed timelines, where delays directly translate into significant revenue loss. The challenge lies in coordinating complex, interdependent activities structural completion, cleanroom build protocols, utility installation, certification, and tool setup within a tightly controlled sequence.
Desapex delivers digitally integrated construction planning through 4D BIM, enabling stakeholders to visualize, coordinate, and optimize every stage of fab construction. By linking time with space, we ensure that construction, certification, and tool installation are executed as a unified, conflict-free process.
Our Digital-First Approach
4D BIM-Driven Construction Planning
All construction, certification, and installation activities are mapped to the 3D model with time-based sequencing.
Core Deliverables
4D Clean Build Sequencing
Planning from structural completion through progressive clean-up to ISO Class certification with contamination control integration.Tool Installation & Hookup Planning
Rigging path analysis, floor penetration coordination, and precise scheduling of tool installation activities.Subfab Utility Coordination
Integrated planning of UPW, CDS, specialty gas, process exhaust, electrical, and control systems across contractors.Cleanroom Certification Planning
Phased FFU activation, particle count validation, and progressive cleanroom area release strategies.ISO 19650-Compliant Information Management
Structured data and document control for multi-stakeholder fab construction environments.Progress Monitoring & Verification
Laser scanning and digital comparison for accurate tracking of structural and utility installation progress.
Why Choose Desapex
In semiconductor manufacturing, time is directly tied to revenue. A delay in commissioning can result in hundreds of millions in lost opportunity.
Desapex ensures that construction, utilities, cleanroom certification, and tool installation are managed as one integrated system. By visualizing dependencies and sequencing in advance, we eliminate bottlenecks, reduce delays, and enable faster, more predictable fab delivery.
Unique Selling Proposition
Desapex’s 4D BIM approach goes beyond traditional construction scheduling by embedding semiconductor-specific clean build protocols and contamination control logic into the model.
This ensures that planning reflects not just construction activities, but the critical environmental and process requirements unique to fabs delivering a level of precision and coordination that generic scheduling tools cannot achieve.
