attached to, is adequately reinforced to accommodate all additional loads created by the new Delta Patio/Carport.
Prior to any footings being commenced it is the Builder/Owner’s responsibility to ensure that the footings will not 
impact on any existing underground services and facilities.
CONCRETE/FOOTINGS
For any connections to an existing concrete slab, it is the Builder/Owner’s responsibility to ensure that the slab is 
structurally adequate to support the additional load.
-  Concrete strength must be a minimum of N25 in accordance with AS 1379-2007.
