Structural Support Systems – Cabling and Bracing
What is structural support and how does it affect tree health and longevity? The Structural Support Systems Workshop will be a 2 day workshop that is lecture based and hands-on. This workshop will cover the ANSI A300 Part 3 Supplemental Support Systems standards that are applied to the installation and maintenance of tree support systems, including cabling, bracing and guying. Various cabling approaches will be discussed such as bracing for split trees, through rods, and outside the box support systems. Static versus dynamic cabling systems will be compared, looking at where, when and why to install each system. Looking at structure support of weakened unions, wind dampening, and supporting abnormal growth structure, we will take a comprehensive approach at the purpose of cabling a tree and which system would likely be most successful. Cabling system construction and installation practices will be discussed to focus on the approach to find the most effective system to fit the tree.
This workshop will cover:
- Basic understanding of the ANSI A300 Part 3 Standards
- Tree structure and stability, what common structural issues require supplemental support systems
- Fundamentals of static and dynamic cabling systems including various configurations, approaches, and outside the box support systems
This workshop also include:
- Hands-on dynamic cabling installation practice
- Display of static cabling hardware and discussion of different systems and approaches
- Field discussion, students will walk through arboretum to identify structural concerns with trees and offer ideas for support systems to mitigate the poor structure or abnormal growth habit.
Location: Washington Park Arboretum, 2300 Arboretum Drive E, Seattle, WA 98112
