Arborist for Architects, Town Planners & Design Consultancies NSW — GIS-Ready Tree Data into Your CAD, Revit or ArchiCAD Environment

Run a PAR at concept design stage, before the design is locked. PARs identify the high-constraint trees, the NRZ / TPZ envelopes the design has to work around, and any show-stoppers (TPZs over the only viable building envelope, hollow-bearing trees requiring retention, encroachment classifications that push the design into Major territory). Architects who run a PAR before the DA rarely get caught by an AIA-stage redesign. PAR is around $1,500 + GST — cheaper than one hour of architectural rework on a finalised drawing set.

Yes — this is one of the reasons referrer architects pick us. Tree positions delivered in DWG (layer-structured for direct import into AutoCAD, BricsCAD, MicroStation), GeoPackage, Shapefile, KMZ, GeoJSON, CSV / Excel. cm-level positioning from Trimble R2 + RTX. For Revit / ArchiCAD environments we deliver the underlay drawings the BIM model can reference. If your firm has a specific layer-naming convention, attribute schema, or coordinate system, we’ll match it.

The combined PAR + AIA package is structured so the AIA reuses the survey, calculation and assessment work the PAR already completed — the AIA stage is faster and cheaper than starting from scratch. Combined cost typically lands close to what a single-stage AIA alone would cost. Your client gets the design-stage diagnostic AND the DA-stage compliance report for roughly what they’d pay for just the AIA. We bundle the pricing at scoping.

Yes — routinely. For projects where the tree resource is a design driver (heritage blocks, large-block residential, complex urban infill, public-realm projects), we’ll join concept-design workshops, DA development reviews and CA-phase sign-offs with the design team. Engagement structures from one-off project workshops to ongoing retained referrer relationships.

Town planners typically engage us at the DA preparation stage: AIA for the lodgement, with the methodology, the NRZ/TPZ calculations and the encroachment classification structured to match the council DCP requirements. We work with most Hunter Region councils, Mid North Coast councils, Central Coast councils, and Sydney councils — including DCP-specific requirements where they exist.

Yes — our Root Investigations service uses our in-house Air Spade to expose actual root architecture under proposed foundations, retaining walls and services trenches. The structural engineer detailing to actual root data rather than worst-case assumptions can right-size foundations (cheaper and faster build) or document where retention isn’t structurally compatible with the proposed structure. Most consulting arborists either don’t own the Air Spade kit or sub-contract it — ours is in-house, same-week mobilisation.

For DA submissions where mature tree removal is proposed and the council expects amenity-value documentation (especially heritage trees, signature site trees, or removals into council-managed adjacent reserve land), we can include a Burnley Method Tree Valuation as a discrete chapter inside the AIA — methodology cited, calculation shown, defensible. Strengthens the cost-benefit case for the consent authority.

AS 4970-2025 (Protection of Trees on Development Sites) for AIA / TPP / PAR. AS 4373 (Pruning of Amenity Trees) for any pruning specifications. Local council DCPs for council-specific requirements. ISA TRAQ for risk assessment work. Burnley Method (Moore 1991, revised) for valuations. Arboriculture Australia Minimum Industry Standards for work-practice baselines.
