Cleanroom & Controlled Facility Fit-Outs
Controlled cleanroom environments built to stringent particulate and pressure differential standards.

Governing Standard
ISO 14644-1 / EU GMP Annex 1 / FDA cGMP Standards
Service Overview
Specialized mechanical and civil fit-out engineering for pharmaceutical, biotech, and electronic manufacturing spaces. We deliver ISO Class 5 to 8 clean environments from initial partition installation to HEPA qualification.
Plant Equipment & Systems Covered
- PIR and rockwool flush modular cleanroom partition walls and walk-on ceilings
- Terminal HEPA/ULPA filter units with integrated gel seals and aerosol test ports
- Differential pressure cascade control systems with motorized balancing dampers
- Air shower tunnels, pass-through boxes, and interlocked hermetic door systems
- Seamless anti-static epoxy and coved vinyl flooring with ESD earthing points
- Clean utility piping for purified water (PW) and oil-free compressed air
Standard Execution Procedure
- [1]Airflow pattern simulation and cleanroom classification layout planning
- [2]Erection of flush non-shedding ceiling grids and partition joints silicone-sealed
- [3]HVAC balancing to maintain positive pressure cascades (10-15 Pa per step)
- [4]Particulate count testing, HEPA filter integrity testing (DOP/DEHS), and recovery runs
- [5]DQ/IQ/OQ commissioning documentation packs for regulatory health audit approval
