Prior to construction works, the site arborist should consult with the
construction company to outline appropriate tree protection methods during
construction, to convey the importance of tree protection, and open
communication channels.

The construction company is responsible for all tree protection procedures on
the site as per these specified recommendations, whenever the site arborist is
not on site. It is the responsibility of the builder to advise the site arborist of
when their presence is required on site or of any breaches of the tree protection
procedures.

All trees being retained as specified by Sunshine Coast Regional Council on
site should be appropriately marked by the site arborist.

Tree Protection Fencing (where used or designated) is to consist of 1800mm
high chain mesh fencing as per AS 4970-2009 or similar appropriate fencing
approved by the site arborist. TPF is to be installed as per TPZ radius
measured as per AS4970-2009, 12 times trunk DBH. The site arborist
should document any modification to the TPZ or TPF.

All TPF will have signage indicating the importance of tree protection, the
arborists contact details, and that it’s a hanging offence to disregard these.

The construction workers or subcontractors working on the site are to be
informed of tree protection importance by the contractor.

The site arborist and the contractor should agree upon and designate storage,
dumping and wash areas that will not impact on any TPZ.

Any pruning or removal works required (such as deadwood removal or
clearance pruning, selective removal of Phellinus infected branches), including
root pruning, shall be carried out by the tree contractor to Australian Standards
AS 4373 —2007 ‘Pruning of Amenity Trees’.

During Construction

The site arborist shall be present to supervise any excavation, trenching or
construction located on the site that may affect any tree roots within a
designated TPZ, and shall keep a record of works to present to the project
supervisor after completion of construction.

Access within a TPZ for foot traffic will be done only as per guidelines
described within 4.5 of AS 4970-2009.

Absolutely no machinery traffic is allowed within a TPZ.
Where possible the first 500mm of any excavation should be dug by hand or

other appropriate method designated by the site arborist to identify any
significant tree roots (25mm or greater in diameter).
