bimTREEs - better planting design for BIM

Leveraging the benifits of BIM in planting design
with complete, parametric, dynamic BIM objects for trees and shrubs

Test version available

bimTREEs are available for test users. The free test set includes 5 trees with some selected sizes (free). There is an extnded set available , that includes 50 trees and large shrubs with tree nursery stock information for Switzerland (license fee).

Leveraging the benifits of BIM in planting design

Reduce errors and omissions thru clash detection above and below ground with predicted growth of crown and root
Transparent cost estimation and correct specifications thru standardized tree nursery data
Growth simulation start with size according to specified quality
Analysis, simulation and optimization during planning process by coupling growth estimation with landscape performance dat (i.e. carbon dioxid sequestration)
Improved collaboration thru standard compatible data exchange (COBie, IFC, cityGML, DIN)
Improved site logistic and asset management from nursery to planting place thru creation of machine readable labels from BIM data and GPS tracking
Handover of correct and complete information (positions, source, delivery data, planting data, contractor) to facility management
Better communication with stakeholders thru VR created by streamlined process for replacement of BIM objects with high quality glTF objects

Ecosystem service analysis

Trees provide numerous ecosystem services to moderate microclimates and improve environmental conditions, including carbon storage, reduction of rainwater runoff, pollutant filtering, shading, cooling, and mitigation of heat island effects. Methods for measuring and predicting tree dimensions, including the crown projection area, crown volume, and leaf area, enable arborists, planners, and researchers to model the growth and benefits of urban trees. The fully parametric bimTREEs allow to ecosystem services over time based on predicted growth.

Cescatti asymmetric hull model

Growth Tila cordata

The science behind

Crown models are based on the asymmetric hull model from Cescatti, simplified to symmetric forms described by well established tree meansurment data (Height, Height of clear stem, Largest crown radius, Height of largest crown radius) and adjusted for root volume
Starting values based on selected tree quality at planting time derived from tree nursery stock data
Chapman-Richards growth function separeted for each major parameter, based on on plant growth in nurseries and urban settings
Unique identifier for each tree over complete lifecycle
