Tunnelling & Underground SpaceTunnel Ventilation, Fire & Life Safety
Atkins provides a wide range of services convering all aspects of
road and rail tunnel safety, including ventilation, risk analysis and
fire safety. Atkins’ expertise has been gained over many years of
involvement in major public and private sector infrastructure projects
and goverment-funded research projects.
Our Tunnel Ventillation, Fire & Life Safety team has a long history of
providing specialist expertise and innovative engineering solutions to
ventillation and safety challenges in complex tunnel projects.
Our engineers are committed to providing specialist services for all
aspects of tunnel ventillation. We also provide expert witness services
in support of design applications, appeals and arbitration.
Our skills and services include
• Design and analysis for ventilation of road and rail tunnels, metro
systems and other forms of tunnels
• Aerodynamic and thermodynamic analysis for tunnel systems
Design for refurbishment of tunnel ventilation and fire safety
systems
• Escape route planning and rescue concepts
• Computational Fluid Dynamics (CFD) and fire modelling
• Quantitative and implementation of tunnel ventilation and
pollution monitoring
• Post-inciddent investigation and analysis
Ventilation and Life SafetyA3 Hindhead
Atkins was commissioned by the Highways Agency to develop the A3
Hindhead improvement scheme, inlcudiing a 2km twin-bore road
tunnel, to sufficient detail for the tender of the ‘early contractor
involvement’ (ECI) design and build contract. In the course of the
development of the illustrative design, Atkins made technical and
operational proposals for the tunnel.
Safety objects were established and analysis carried out of the
operational hazards. Quantitative assessment of risk, including time-
line analysis for incident development and modelling of vehicle fires
using computational fluid dynamics, contributed to the development
of the tunnel configuration and fire and emergency strategies.
Aero and thermodynamicsMetronet, Ventilation Analysis
Atkins was commissioned by Metronet to perform the aerodynamic
and thermodynamic modelling of the Victoria Line underground
system of tunnels, shafts and stations with existing rolling stock. In
addition, predictive modelling of temperature and airflows on the
line with proposed new rolling stock, timetables and passengers was
carried out.
Modelling and Monitoring Birmingham City tunnel refurbishment
Atkins has recently been commissoned by Birmingham City Council to
develop the feasibility and outline design for the refurbishment of a
number of road tunnels situated on the busy approach road to the
city. Design and analysis work has included modelling of present and
future vehicle emissions using complex 1D transient software.
Measurements were also carried out to provide data for the
verification of modelling data and to provide confidence in design
parameters used in the development of the ventilation design
concepts.
Quantitative Risk Analysis Dangerous Goods Transport QRA, UK road tunnels
Atkins was one of the three partners commissioned to develop the
OECD/PIARC QRA Model for the analysis of risk associcated with the
transport of dangerous goods through road tunnels; a model that is
used for the analysis of dangerous goods transport risk, as required by
the EU Directive on minimum safety requirements for road tunnels.
Atkins expert have applied the model to a number of UK road tunnels
to provide information to support the decision making process
regarding tunnel categorisation and prohibitions for dangerous goods
vehicles.
