Fire Check Consultants were appointed to provide a performance-based fire safety strategy for a proposed residential site containing thirty-eight Class 2 Sole-Occupancy Units above a Class 7a carpark. NCC DtS provisions require the building to be constructed from Type A construction due to the 3-storey residential unit arrangement. Performance Solution was applied to rationalise the Type of construction to Type C in lieu of Type A. The engineered solution was intended to adequately fire separate the Class 7a basement carpark from the 3-storey Class 2 sole occupancy units and to demonstrate the Class 2 portions of the site would reflect the arrangement of a typical 3-storey Class 1a townhouse development.

After ensuring the compliance of all aspects of Fire Engineering Report Performance Requirements and Design Compliance Declaration.
