Associate - Mechanical (Airport)

WSP; Dadri; On-site; INR 1,500,000 - 2,400,000; Full time

Job summary

WSP is seeking an experienced HVAC/Environmental design engineer for aviation facilities. Responsibilities include leading mechanical design from feasibility to construction support, and developing energy-efficient strategies for large hangar volumes and catering zones.

You will coordinate BIM workflows across disciplines, perform ventilation load calculations, and guide retrofit projects within active airport environments while ensuring safety, energy performance, and regulatory compliance.

Responsibilities

• Lead HVAC/mechanical design from feasibility through detailed design for aviation facilities.
• Own environmental strategy for large volumes: heating/cooling, destratification, purge/exhaust, make-up air, controls.
• Engineer specialist ventilation for hazardous operations: paint booths, fuel-cell purge, welding fumes, VOC control.
• Integrate process utilities common to MRO and workshops.
• Shape catering facility HVAC and hygienic air zones: kitchen exhaust & makeup air per NFPA 96.

Job description

Responsibilities

• Lead mechanical/HVAC design from feasibility and basis-of-design (BoD) through detailed design, tender and construction support for aviation facilities.
• Own the environmental strategy for very large volumes (e.g., hangar bays): heating/cooling concepts, destratification, purge/exhaust modes, make-up air, and controls sequences—balancing energy, IAQ and safety. (UFC/ASHRAE/NFPA context).
• Engineer specialist ventilation for hazardous operations: paint spray booths/rooms, fuel-cell maintenance/purge ventilation, welding/fume extraction, VOC control, and hazardous-area interfaces with electrical/controls.
• Integrate process utilities common to MRO and workshops.
• Shape catering facility HVAC and hygienic air zones: kitchen exhaust & makeup air (NFPA 96), pressure cascades, temperature/humidity control for clean prep/packing.
• Deliver BIM-led coordination (Revit/Navisworks) across architecture, structures, process, fire protection, and controls; lead clash resolution and model QA.
• Run calculations & simulations: loads, duct/pipe sizing, ventilation rates, smoke/fume capture, and (where needed) CFD to support the thermal comfort studies.
• Author technical documents: BoD, design reports, specifications, sequences of operation, control narratives, FAT/SAT/commissioning plans.
• Engage stakeholders—airlines/MROs, airport operators, food safety teams, and authorities to secure approvals and smooth delivery.
• Lead retrofit, refurbishment, and brownfield upgrade projectswithin operational airport environments—assessing existing systems, developing phased upgrade strategies, ensuring minimal disruption to ongoing operations, and integrating new systems with legacy infrastructure while addressing capacity, compliance, and energy performance improvements.
  Key systems & domains you’ll cover
• Hangars & workshops: general and emergency exhaust, purge ventilation for fuel system work, floor-level capture where required, destratification/HVLS fans, door air management, radiant/air systems, PCA (pre-conditioned air) and GSE interfaces.
• Catering facilities: high-duty kitchen exhaust & makeup air (hoods, MAUs, heat recovery), grease ducting, rooftop terminations, pressure zoning for hygiene, and interfaces to cold rooms/freezers and clean areas.
• Experience in refurbishment projects, passenger terminal building Mechanical design (HVAC, Drainage systems) is preferred.
