Arboricultural Impact Assessments & Project Arborist Services in Sydney

Trees hold up a DA when they turn up late: an encroachment nobody drew, or an AIA that doesn't match the final plans. We fix that by getting the tree information to your team first.

Synertree is a consulting arborist practice led by Mathew Phillips (AQF Level 5, Diploma of Arboriculture, Advanced QTRA No. 6067, ISA TRAQ). Here's how we work with architects:

• Pre-AIA. We survey the trees over your survey base plan (GNSS Trimble where needed) and send you the tree data (locations, TPZs and SRZs) as ArborCAD plan sets for every discipline on the project, with early design guidance while the design is still flexible.
• AIA on the submission documents. Once all disciplines finalise their designs, our ArborCAD impact assessment calculates every proposed encroachment, so council sees the full extent of the impacts.
• Project arborist. Tree protection plans and certification from demolition to OC.
• Root mapping (non-destructive). Where a structure, driveway or service must go inside a TPZ, we expose and map roots with Airspade non-destructive excavation, giving you and council evidence of what's actually there. It often allows designs a desktop assessment wouldn't.
• Also: Tree Protection Plans (ArborCAD), tree management plans, pruning specifications, tree risk assessment (QTRA / TRAQ), statements of evidence and pre-purchase due diligence.

We've worked closely with all Sydney LGAs and on councils' own projects. We know what assessors look for, which means fewer RFIs and a faster path to determination. We don't do physical tree work, so our advice stays independent. We Represent the Trees.
