Background
A pharmaceutical manufacturing site in India required significant remediation support to bring its HVAC
and Building Management Systems (BMS) into alignment with international regulatory requirements.

Challenge
The facility faced gaps in system design, qualification, and data integrity that put compliance and product quality at risk. Both the HVAC and BMS required extensive requalification, improved controls, and updated documentation to ensure adherence to standards such as 21 CFR Part 11 and EU Annex 11.

Approach

• Conducted a comprehensive GAP analysis for HVAC and BMS, identifying system shortcomings.
• Developed new User Requirement Specifications (URS) and Design Specifications to align with current regulatory expectations.
• Led system remediation activities, including:
  • Creation of updated HVAC and BMS drawings.
  • Full recommissioning of HVAC to verify environmental performance.
  • Improvements to the BMS, including user access levels, administration procedures, and robust data backup/retention policies.
• Authored and executed DQ, IQ, OQ, and PQ protocols for HVAC, BMS, and facility systems.
• Delivered training to local personnel on validation practices, with a strong focus on data integrity and Good Documentation Practices (GDP).
• Rolled out site-standard computer systems requirements to ensure compliance with 21 CFR Part 11 and EU Annex 11.

Outcome

• Successful requalification of HVAC and BMS systems, ensuring compliance with international standards.
• Strengthened site data integrity practices and documentation culture.
• Enhanced regulatory readiness and long-term operational reliability.
• Increased local team capability through training and knowledge transfer.

Key Takeaway
Robust remediation and requalification of critical utility systems, combined with targeted training and data integrity improvements, ensured lasting compliance and reliability for a global pharmaceutical manufacturer.
