1. INTRODUCTION
The purpose of this report is to classify the subject allotment in accordance with Australian Standard
2870 - 2011 'Residential Slabs and Footings'. From this classification, a footing system can be recom-
mended for the structure so as to allow adequate performance of the footings under the soil conditions
determined at the site.
Trees: There are small (<5m), medium (5-10m), and large (>10m) trees at this site. Global Testing
recommends an experienced arborist be commissioned to quantify the existing size, location, pre-
dicted maximum height and type of these trees to aid in the design process. It is the responsibility of
the designing engineer to apply the principals of AS2870-2011 Appendix H 'Guide to Design of Foot-
ings for Trees'. The classification herein excludes the effect of trees on the site.
