Throughout the project we were faced with various challenges:

  • With the project at operational buildings there was the need to work around office hours and personnel within each building on each floor.
  • Firesafe had to plan the coordination of products and supplies being delivered within operational hours and as required to reduce an delays to our work as well as minimising disruption to the office.
  • Site inspections completed extensively before commencing works to determine what items were no longer compliant or what items could still be utilised.
  • Limited knowledge by contractor of the history of certain systems so Firesafe had to conduct their own investigations to determine the viability of systems to ensure compliance with the Building Code of Australia.
