Grant Associates, in collaboration with Wilkinson Eyre Architects, Atelier One, Atelier Ten, and Land Design Studios, developed the winning concept for Singapore National Parks Gardens by the Bay at Marina South - the heart of Garden City and home to the Singapore Garden Festival. Key features of the Marina South development which RWDI provided our expertise on are the unique Conservatory Complex (two biospheres with cool dry and cool moist microclimates) and the iconic Super Trees (30m to 50m tall).
RWDI's wind analysis helped the design of the components of the structures, including the glass, framing, gridshell and sun-shades of the Conservatories, and the outer planted 'skin' and core structure of the Super Trees.
- Cladding and structural wind loading
- Wind pressure distributions
- Rain loading
- Risk-based analysis
Detailed analysis of key environmental parameters: Appropriate design loads were achieved through the application of advanced tools to determine wind speeds and rain loads.
Increased comfort and experience: Managed and controlled wind patterns to provide conditions that suit the desired pedestrian usages around the site.
Client support: RWDI successfully lobbied for a 50-year return period 3-second gust wind speed of 32 m/s by providing an extreme value analysis of the local wind speeds.
Reduced structural costs: RWDI’s support, consultation and analysis resulted in reduced wind loads and reduced roof rainfall loads.
Detailed cladding and structural design guidance: No design guidance exists for unique structures. RWDI established the load guidance needed for the Conservatories and Super Trees. RWDI’s contribution was vital to the success of the design.
