EVC are pleased to announce that we are now undertaking building Internal Tenability Reporting to satisfy the requirements of Specification 43 Section C9 “S43C9” within the National Construction Code “NCC” 2022 Specification 43.
The intent of S43C9 is to provide a framework of protection measures to reduce the risk of occupant harm in a bushfire event. Through efficient air handling system selection and appropriate consideration of the building envelope material properties, the heat and smoke infiltration risks associated with internal tenability can be minimised in line with the NCC.
In conjunction with project stakeholders and the project design team, EVC can undertake computational fluid dynamics (CFD) modelling, analysis and reporting to provide advice on the building fabric and air handling systems.
This assessment report will identify and outline how compliance with S43C9 Internal Tenability can be attained for the proposed building based on its specific use and environment.
EVC recommend obtaining advice prior to applying for development approval and whilst in early discussions with town planners, the building’s geometry and planned site orientation could be well considered to improve the ability of proposed buildings to passively resist a bushfire attack whilst making consideration of desired aesthetics, building function and construction methodology.
Should you require further information or a Fee Proposal, please contact us via email enquiries@evcengineering.comm.au or by calling the office on 02 4929 2461.
