Mark worked on the fire engineering alternative solution and construction stages of Project Renaissance for Interface Australia following the July 2012 fire that destroyed its Picton factory. As part of the design of the alternative solution, Mark was involved in reviewing the exit arrangements, travel distances, compartmentation, smoke hazard management etc which were all rationalised, adding significant cost-benefit to the project. One of the main components of the design was the 3D computer fire and smoke modelling to look at the effects of fire and smoke spread in the building, in order to demonstrate that the acceptance criteria for life safety and fire service intervention was satisfied. Following acceptance of the design by the relevant stakeholders and fire engineering peer review, Mark was involved in the pre-occupation inspection stages and approvals process to review the works against the accepted fire engineering design, to ensure it was consistent.
