Engineering Lifecycle

From Concept to Certified Handover

A proven 5-stage turnkey methodology powered by 3D Building Information Modeling (BIM Level 2), aerodynamic CFD simulations, and rigorous GAMP 5 qualification.

Structured Delivery

The REINWERK 5-Stage Execution Framework

Ensuring zero ambiguity, strict adherence to budget, and guaranteed compliance at first-pass validation.

01

Consultation & URS Definition

Typical Duration: 1 - 3 Weeks
Strategic Requirement Engineering

Every successful cleanroom starts with a rigorous assessment of process requirements, contamination risks, personnel flows, and regulatory boundaries. We formulate an auditable User Requirement Specification (URS) and establish the architectural baseline.

Key Engineering Activities:

  • Process flow analysis and contamination risk assessment (FMEA)
  • Zoning of cleanliness grades (ISO 14644-1 and EU-GMP Annex 1)
  • Formulation of User Requirement Specifications (URS)
  • Space planning, structural feasibility, and utility connection audits

Documented Deliverables:

  • User Requirement Specification (URS) Dossier
  • Conceptual Cleanroom Zoning Layout
  • Classification & Pressure Cascade Matrix
  • Preliminary Capital Budget & Timeline
Governing Standards: ISO 14644-4 (Design & Construction) ISPE Baseline Guides
02

3D BIM Engineering & Simulation

Typical Duration: 2 - 4 Weeks
Clash-Free Digital Modeling & CFD Airflow

Using cutting-edge Building Information Modeling (BIM Level 2) and Computational Fluid Dynamics (CFD), we design the architectural envelope, HVAC ductwork, ceiling grids, and piping in millimeter precision before fabrication.

Key Engineering Activities:

  • Multi-disciplinary 3D BIM modeling (LOD 350 / 400)
  • CFD airflow simulation to identify dead zones and ensure laminar uniformity
  • Clash detection between structural beams, ductwork, and process piping
  • Detailed bill of materials (BOM) and fabrication shop drawings

Documented Deliverables:

  • 3D BIM Model (Revit / IFC format)
  • CFD Aerodynamic Airflow Analysis Report
  • HVAC Thermodynamic Load Calculations
  • Approved Fabrication & Installation Drawings
Governing Standards: DIN EN ISO 14644-4 VDI 2083 Part 1-3 Eurovent Ductwork Standards
03

Off-site Prefabrication & Construction

Typical Duration: 4 - 8 Weeks
Precision German Manufacturing & Swift Erection

Cleanroom components are precision-manufactured under factory-controlled conditions. On-site installation is carried out by certified cleanroom assemblers using non-particulate methods, slashing on-site construction time by up to 50%.

Key Engineering Activities:

  • CNC precision fabrication of monobloc and cassette wall panels
  • Factory assembly of dynamic pass-through boxes and air showers
  • Rapid on-site installation of wall partitions, walkable ceiling, and doors
  • Application of seamless coved epoxy or welded static-dissipative vinyl flooring

Documented Deliverables:

  • Factory Acceptance Test (FAT) Certificates
  • Installed Architectural Cleanroom Shell
  • Airtight Envelope Pressure Test Report
  • Clean Construction Protocol Compliance Log
Governing Standards: EN 13501-1 (Fire Classification) EN 12207 (Airtightness)
04

HVAC Commissioning & Air Balancing

Typical Duration: 1 - 2 Weeks
System Integration & Microclimate Calibration

With the physical envelope sealed, our mechanical engineers install terminal HEPA/ULPA filters, calibrate airflow velocities, balance room pressure cascades, and tune precision climate controls to achieve stable steady-state conditions.

Key Engineering Activities:

  • Installation and leak scanning of terminal H14 HEPA / U15 ULPA filters
  • Airflow velocity balancing across all supply diffusers and return air grilles
  • Calibration of room differential pressure cascades (10 to 25 Pa deltas)
  • Fine-tuning of PID controllers for temperature (±0.2°C) and humidity (±2% RH)

Documented Deliverables:

  • Air Balancing & Flow Rate Report
  • Differential Pressure Cascade Map
  • Temperature & Humidity Stability Logs
  • Terminal Filter DEHS Scan Certificates
Governing Standards: DIN EN ISO 14644-3 (Test Methods) VDI 2083 Part 4
05

Validation, Qualification & Handover

Typical Duration: 1 - 2 Weeks
Audit-Ready DQ / IQ / OQ / PQ Certification

Our certified validation engineers conduct comprehensive qualification testing following GAMP 5 and ISO 14644 standards. We provide an audit-ready qualification dossier and hands-on staff training before final operational handover.

Key Engineering Activities:

  • Airborne particle count sampling 'at-rest' and 'in-operation' (ISO 14644-1:2015)
  • Smoke pattern visualization studies (airflow direction and turbulence profiling)
  • Cleanliness recovery rate testing (measuring 100:1 particle purge time)
  • Compilation of comprehensive DQ, IQ, OQ, and PQ validation dossiers

Documented Deliverables:

  • Formal Cleanroom ISO 14644-1 Classification Certificate
  • Complete IQ / OQ / PQ Qualification Dossier
  • Airflow Visualization Video Documentation
  • Facility Operation & Preventative Maintenance Manuals
Governing Standards: DIN EN ISO 14644-1:2015 EU-GMP Annex 1 FDA 21 CFR Part 211 GAMP 5
