Sector / Field: Batteries / Industry / EPC Projects (Gigafactories) – industrial buildings with high environmental constraints (dry rooms, clean utilities, high-capacity HVAC)
Location: Dunkirk, France
Context
-
Development of battery gigafactories.
-
Complex industrial buildings: “ultra dry” rooms, sensitive process areas, clean utilities.
-
Large-capacity HVAC networks, HEPA/ULPA filtration, energy recovery, dust management, controlled atmospheres.
Main Responsibilities
1. HVAC Design and Studies
-
Sizing: thermal and airflow calculations, flow and pressure loss calculations, sizing of AHUs, fans, cooling/heating coils, air treatment systems for dry rooms.
-
Plans and diagrams: P&IDs, HVAC schematics, piping layouts, openings, BIM models (Revit MEP).
2. Process & Utilities Integration
-
Consider thermal loads from processes (coating, mixing, calendering, assembly).
-
Define technical interfaces with HVAC, sprinklers, electrical systems, automation, utilities (chillers, steam, hot water, compressed air), dry rooms and sensitive areas.
-
Manage humidity control and HEPA/ULPA filtration according to process needs.
3. Technical Follow-up and Site Support
-
Validation of execution studies and technical reviews (VISA).
-
Respond to RFIs and handle technical discrepancies.
-
Participate in FAT/SAT for AHUs, dehumidifiers, and special HVAC equipment.
-
Provide technical support on site: spot checks, commissioning, performance testing, balancing.
4. Documentation and Project Management
-
Draft technical specifications, datasheets, and technical notes.
-
Participate in bidding processes and contractor selection.
-
Track schedule, deliverables, and report to Lead Facilities Engineer.
-
Conduct BIM reviews and multidisciplinary coordination.
