Safety is of utmost importance for all users of rooftop greenery. In this course, participants will learn about rooftop greenery designs, safety consideration as well the recently introduced Workplace Safety and Health (Design for Safety) regulations introduced by Ministry of Manpower (with effect from 1 August 2016). The Design for Safety on Rooftop Greenery is part of CUGE's Training Series on Guidelines to continue our efforts in improving the overall horticulture standard of the landscape industry.

This program will provide an overview on design of rooftop and vertical greenery, the safety factors for consideration, and how these safety requirements are influenced by:

  1. Types of structures and plants
  2. Types of rooftop greenery
  3. Safety considerations for maintenance

The rationale behind these design recommendations will also be shared.  The course aims to impart to participants a realistic perspective on the many needs of trees and palms when planted on the rooftop, as well as the various associated architecture, loading and placement issues that need to be considered upfront during the project design phase, with the overall intention of encouraging feasible and manageable rooftop greenery design.
