Ventilation Design

The Air is Clean

Air flow, dust control, diesel particulate contamination, power consumption and noise abatement are just some of the key factors that need to be considered when designing in-tunnel ventilation systems.

Grydale has extensive experience in tunnel ventilation design. Our engineering team are able to prepare a comprehensive design to control air quality in accordance with regulations and site requirements.

Air flow, control of dust and diesel particulates contamination, power consumption and noise abatement are all key areas that are taken into consideration along with being able to make recommendations for in-tunnel environmental monitoring systems.

Our approach to the design of ventilation plans is as follows:

– Prepare a high-level comparison of ventilation options, providing advantages and disadvantages of each approach.
– Recommend and present the most favourable ventilation option.
– Collect data to prepare a systems level specification and concept design.
– Undertake detailed design for each phase of construction, prepare and present a design documentation pack.

For the duration of the works, Grydale are able to provide project management and engineering support for the ventilation works and provide updated plans if site conditions or requirements change.

We use a range of numerical simulation tools to prepare the design, including:

– Ventsimâ„¢ DESIGN 5 for ventilation design and simulation.
– Autodesk CFD for three-dimensional ventilation design and simulation
– Autodesk Inventor for mechanical/structural design, if required.
– Verification by model review, structural simulation, or hand calculations as appropriate.
