This module explain the steps involved in approving the fire safety aspects of building work and
the interaction between building regulations and other statutory fire safety requirements in
England and Wales.
It aims to ensure that developers and designers will be able to receive all the fire safety
information relevant to Building Regulations and other statutory approvals in time to avoid
abortive work. If followed there should be no need for extra building work to be done at the end
of a building project, before the building can be occupied for its intended purpose
