CS ArtisanRV Features: Import Existing Tree Survey Information

CS ArtisanRV Features: Import Existing Tree Survey Information

“This has the potential to show both current and proposed landscapes in a far more realistic manner aiding the decision making process.”

Accurate survey information is critical through construction project phases and to establish the starting (access) point for the whole life-cycle focus of BIM workflows.

Trees are important elements of green infrastructure, contributing to urban cooling through evapo-transpiration and providing micro-climatic effects that positively impact on energy demands in the built environment.

In the UK, BS5387:2012 is intended to assist decision-making with regard to existing trees in the context of design, demolition and construction. Root systems, stems and canopies are needed to be taken into account in all projects along with allowance for future movement and growth and the early provision of physical protection is critical.

The beauty of the above British Standard is that it follows a logical sequence of events that are wholly appropriate for BIM.

  • Initial tree survey and categorisation
  • Identification of constraints and Root Protection Areas (RPAs)
  • Identification of trees for retention and removal
  • Identification of pre, during and post-construction operations

So how can this be done?

Import Parameters

Tree surveys are carried out by arboriculturalists using hand-held devices in the field and are recorded in in a standard file format. CS ArtisanRV enables this source survey information to be imported directly into a Revit environment via a mapping utility that associates survey fields with Revit family parameters.

Import-Parameters BIM Tree Survey

View and Edit

Imported Tree Survey information is loaded as Revit Family instances and users are able to view and edit source information as required.


Colour, Categorise and Calculate

Various options are available to place Existing Trees in the model which should be geographically aligned to the Eastings and Northing coordinates used in the tree survey.

Existing Trees are placed in Plan View categorised by colour to denote quality and value in outline with accurate representation of tree canopies measured at four cardinal points. The Root Protection Area (RPA) is calculated based on the recorded stem diameter that is displayed as a dashed line around individual trees.

Users have the option of displaying Existing Tree information in Plan View as either outline of colour fill. There is a quick key to switch between preferred displays.


Auto-size and view in 3D

Existing Trees are placed in 3D views hosted to the topography and are sized automatically by dimension parameters recorded in the imported tree survey.


Format and Filter

An Existing Tree Schedule records all underlying information from the imported tree survey, providing an accurate repository of all model information however it is viewed.

The schedules is simply a view of the same model information and users are able to Edit Fields, Filter, Sorting/Grouping, Formatting and Appearance as required.


Identify and Zoom

An Object Browser provides a centralised tool to view all Existing Tree content and to provide a quick way to identify and zoom to specific Existing Tree instances in the current Revit model.


Using Revit Phases for Existing Trees

Phases in Revit represent a distinct time period in the life of the project. Existing Trees are placed on Phase Created – Existing Tree Survey.


Revit tracks the phase in which views or elements are created or demolished and phase filters can be used to control the flow of building model information into views and schedules. This allows you to create phase-specific project documentation, complete with schedules.

Using the Object Browser, users can sort Existing Trees by Retention Category and then select trees that are marked for Removal. Setting the Phase Demolished to New Construction means that Phase Filters can automatically detect trees marked for Removal so that when opening a New Construction (proposed design) phase, Existing Trees to be removed are automatically Not Displayed.

Fully-informed 3D Model

Using Revit Phasing and Filters alongside CS ArtisanRV Existing Tree utility equates to managing fully informed 3D model content from existing survey information and throughout the entire project life-cycle:  BIM for Landscape workflow in action.3D Landscape Model
