Outstanding Platform for Talent

Job Description

Role Overview

Lead the design and engineering of tunnel ventilation and smoke control systems for road and/or rail tunnels, covering normal ventilation (comfort/air quality), emergency ventilation (fire/smoke control), jet fan and ducted systems, and full integration with Fire & Life Safety (FLS) requirements and authority expectations. The role requires strong capability in 1D network modelling, 3D simulation and CFD to support design decisions, performance verification, and safety case documentation.

Key Responsibilities

Develop and manage the Tunnel Ventilation Basis of Design, design criteria, and performance requirements for normal and emergency ventilation systems across concept to IFC and construction support.
Design and size tunnel ventilation systems, including as applicable:
Longitudinal / semi-transverse / transverse ventilation configurations
Jet fans, axial fans, supply/exhaust fans, smoke extraction systems, dampers, ducts, shafts, portals and ventilation buildings
Ventilation control philosophy (modes, scenarios,



sequences), redundancy and maintainability requirements
Perform and lead comfort and air quality analyses for normal operations:
Contaminant dispersion and compliance with exposure limits (CO/NOx/visibility as applicable)
Thermal comfort, airflow velocity limits, and user comfort criteria for road/rail tunnels and underground interfaces
Support operational strategies for congestion, maintenance modes, and seasonal conditions
Lead fire and smoke control engineering in coordination with FLS/Fire teams:
Define design fire scenarios, critical velocity, backlayering control, smoke stratification considerations, tenability criteria
Coordinate interfaces with egress routes, cross-passages, emergency exits, pressurization systems, and fire service access requirements
Develop ventilation response strategies for different incident locations and ventilation zones
Prepare and/or supervise simulation and mode
