Arborist Inspection Report 16-8-21 · OPW22/0022

                     Property and Tree Protection Methodology
                     We recommend is to install a physical root barrier to between 600mm to 1200mm in
                     depth and for the extent of the defined space ( approx 60m ).
                     This would involve vacume excavation approximatly 1 m from the toe of the building .
                     Because of the unknown depth of the root profile , we would take a cross section and
                     customise the depth so ans to ensure true protection of the building.
                     Once trenched and prior to to root barrier instalation we recommend the addition of
                     Bentonite Clay which is a root ihibitor and discourages root growth also as an added
                     barrier




                     Tree Protection Methodology
                     All tree protection is as identified in AS4970-2009 and in accordance with AS4973 -
                     2007 and all works to be supervised by Level 5 Arborist in conjunction with Arboreal.
                          1. All excavation to be done by vacuum excavation.
                          2. All root pruning to be done by cleaned silky saw.
                          3. Trench to be backfilled after the root barrier and Bentonite Clay installation with
                             mature forest mulch.
                          4. Will need a dial before you dig prior to commencing works.
