7 T REE P RO TECT ION G UID ELINES
For the proposed retention of the trees onsite, the following guidelines are recommended to
be implemented to minimise the impact of the project works. The protection recommendations
offered are guided by, AS4790 – 2009 Protection of trees on development sites, industry best
practices and the supervising presence of a suitably qualified and experienced Arborist with a
high level of experience as an onsite Project Arborist.

The information within these Guidelines is generic for practical use with common sense and
discretion.

The successful retention of the trees will be bettered by the education and cooperation of all
parties of the construction team during the build and the presence of the Project Arborist on
site to assist and advise during the construction phase for all works carried out adjacent to the
TPZ of protected trees.

ALL workers on the site are to be made aware of the Tree Protection Guidelines and any site-
specific measures by the main contractor prior to commencing works.

7.1 THE ROLE OF THE PROJECT ARBORIST AND TREE PROTECTION
An Arboricultural Assessment undertaken by the Project Arborist will outline the trees that
require consideration. The information within these Tree Protection Guidelines should be read
in conjunction with guidelines laid out in the Australian Standard, AS4970–2009 Protection of
Trees on Development Sites and ongoing advice from the Project Arborist.

A designated onsite foreman/supervisor from the construction company is to liaise with the
Project Arborist to ensure that Tree Protection is adhered to in their absence from the site.

A Post Construction Arborist Report can be prepared by the Project Arborist on request for
the retained tree comprising a Visual Tree Assessment detailing each of the trees’ condition
and vigour, damage or disturbance which may have occurred, and remedial works are
undertaken.

After the final inspection, a Certification of Compliance can be supplied along with any
monitoring documentation as required.

The Project Arborist may at any time implement new or additional procedures as may be
required for the site in the best interest of the trees and the development as a whole.
