The design of the HVAC system for the pharma area begins with the preparation of a comprehensive area classification layout, defining the required air cleanliness levels for each room based on the specific process requirements. We carefully map out system zoning and pressure zoning, alongside detailed planning for man and material movement, ensuring proper airflow control and preventing cross-contamination.

Room Data Sheets (RDS) are prepared for each area, followed by precise heat load calculations to determine the appropriate capacity of Air Handling Units (AHUs) in alignment with the system zoning plan. Based on this, we design a robust and efficient HVAC system tailored to the facility’s needs. The duct sizes are designed as per SMACNA standards, and detailed ducting layouts are prepared to ensure uniform air distribution and maintain pressure balance across the pharma areas.

To support procurement, we develop technical specifications and tender documents that clearly define the scope of supply and work. These documents include capacities for AHUs, required ducting quantities, HEPA filter specifications, insulation details, volume control dampers, instruments and control systems, electrical requirements, BMS system integration, and validation activities. These specifications help in floating precise inquiries for the HVAC system.

We thoroughly review technical offers from vendors, conduct technical discussions, compile and evaluate submissions, and recommend the most suitable vendor for HVAC system installation based on both technical and commercial considerations. Once the vendor submits their design and drawings, we carefully review them, suggest necessary corrections, and approve them for execution only after ensuring complete satisfaction with the quality and compliance of the design.

In addition, we design the water chiller and hot water systems for the HVAC setup, preparing detailed technical specifications for chillers, hot water systems, cooling towers, and circulation pumps. The chilled water and hot water piping networks are designed in detail, with piping layouts and Bills of Quantity (BOQ) prepared for procurement. We also design the pipe insulation for both chilled and hot water systems and prepare corresponding BOQs for insulation materials.

The MCC panel for the HVAC system is designed with a complete cable schedule that includes electrical supply planning for AHUs, chillers, cooling towers, pumps, and hot water systems. Throughout the installation phase, we conduct stage-wise inspections and provide technical guidance on-site to ensure that the project execution aligns with the design and maintains the highest quality standards. Finally, we witness the testing and validation of the HVAC system in accordance with ISO 14644-3 testing procedures and, after thorough verification, provide clearance for the operational use of the pharma area.
