Children’s Garden at the Gardens By The Bay, Singapore

Specifications

To provide an ultra-lightweight green roof system to establish green roof on existing rooftops

Solution

VersiDrain® 25P water retention and drainage trays were placed directly over the RC rooftops, ensuring that individual trays overlap by at least one cell row.  A geotextile filter fabric was next laid to completely blanket the trays. Geotextile perimeter upturn of about 15cm is glued to the side walls.

EnviroMix PB, a growing media in the form of a lightweight planting board with high water absorbency and retention properties were next installed. Arranged in rows over the geotextile one abutting against the other without the need to affix, the planting board is extremely easy to install. They are also easily cut to fit into or around irregular areas on the roof.

Minimal regular loose media material is required. Only 50mm of appropriate soil mix (depending on plant species selected) was spread over the planting boards for in-situ planting of selected drought-tolerant plants to establish the green roofs on three rooftops at the Children’s Garden.  For planting of turf/grass, no additional loose media is required over the planting boards making installation much cleaner. Pearl grass was effectively used to create maintenance paths on the green roofs.

Vital nutrients incorporated into the board during its manufacture help support initial plant establishment whilst its high water absorbency and retention properties help to reduce irrigation frequency.  In prolonged dry spells the addition of an appropriate irrigation system helps to maintain and sustain the green roofs.

More than just helping the rooftops to aesthetically blend with the lush greenery of the gardens, the extensive green roofs complement existing solar panels on an adjacent rooftop to support environmental sustainability.  By providing an insulation barrier against the elements on the rooftops, the green roofs also offer protection for the waterproofing as well as reduce heat absorption.

Overseas Family School

Location

Paris Ris Drive 3, Singapore

Specifications

To provide support pedestal for installation of decking.

Solution

6,500 VersiJack® pedestals were used to support bearers for installation of the raised wooden decking on the rooftops of the two Academic Blocks of the school. VersiJack® pedestals allowed easy screw adjustments to be made to bring the pedestals to the required installation heights. Thereafter, Integrated Locking Rings on the pedestals were used to lock and secure the confirmed heights during and after installation.

The 1,994 m2 of decking created turned the otherwise wasted bare rooftops into additional amenity space for the student population and staff of the school, and will inevitably become the preferred outdoor venue where organised events and other school activities may be conveniently staged and carried out within the safety of the school’s compound.

The raised decking also serves an environmental role by providing an effective shield above the rooftops. This reduces heat and sound transfer from the rooftop to the classrooms below, reducing energy consumption for air-conditioning, related energy costs, and also the carbon footprint of the school. Consequently, they also help to mitigate urban heat island effect.

Specifications

To provide green wall system for installation of two green walls

Solution

VGP Mounting Panels were installed onto two walls to facilitate mounting of VGP Trays, from floor to ceiling, two-storey high, at the main entrance hallway of the school and on a lower wall fronting the school’s assembly area. The mounting panel at the bottom right was installed first followed by the other panels of the bottommost row systematically from right to left. Subsequent panel rows follow above in the same sequential order. An automated irrigation system, consisting of a network of tubing and a control panel, was installed to supply irrigation to the individual trays at programmed intervals for pre-set durations.
VGP Trays were planted in-situ with selected pre-grown plants and hung 12 trays to a panel to create a dense and lush wall of plants instantly. Anti-lift arms were inserted into individual trays to prevent inadvertent dislodgment of the VGP Trays from their mounting points. The drainage outlets of the bottommost row of trays were connected to a horizontal base tube to allow excess water to be discharged without wetting the immediate area beneath the green walls.
The lush eye-pleasing green walls become instant living educational tools. They enable students of the school to learn that, for a very small ground level footprint, green walls are able to provide many benefits. They contribute to environmental sustainability, enhance aesthetics, improve health and wellbeing by providing a source of stress relief and escape from the demands of urban living. In the specific context of the school, these green walls offer an environment conducive to learning.

Brisbane, Queensland, Australia

Specifications

To provide the green wall system to establish vertical greenery
To provide the green roof system to establish greenery on sloping roof
To provide pedestal support for installation of pavers

Solution

VersiWall® GM
Twelve free-standing metal framework structures were erected for pilasters to be secured for VGM modules to be anchored such that vertical greenery is possible all around the framework. Pre-planting of the VGM Modules in a nursery environment allowed selected plants to establish and be appropriately orientated prior to installation, creating lush green walls almost instantly at the hospital project at time of installation.</p>
Both the pitch roof and its retaining wall at the edge were also greened with the VGM system. Anchoring pilasters were installed directly onto the pitch roof and the wall for pre-planted VGM Modules to securely anchor. The completed installation turned the pitch roof and wall from what would have been bare, ordinary and unattractive building features into eye-pleasing and therapeutic green roofs and vertical gardens.
A total of 1630 VGM modules were used for this construction.
The skyrise greenery reflects contemporary research that highlights the significant influence greenery and nature in the built environment has on health and wellbeing, especially beneficial in the setting of the children’s hospital.

 

VersiJack
11,000 VersiJack pedestals were installed to support expansive raised paver areas in the hospital grounds. Spacer Tabs and Slope Correctors used on the pedestals enabled consistent gaps between pavers to be maintained and allowed compensation for any slope to fall for drainage on the installation surfaces respectively.
Height extensions and minor adjustments were easily achieved by adding extenders and by screw adjustment of the pedestals, and desired heights locked down with the pedestals’ integrated locking rings. The void created beneath the paver platforms allowed miscellaneous services to be hidden.

 

The vertical greenery, sloping green roof and raised paver areas of the hospital form a protective and insulating shield that helps to cool the hospital building. Not only eye-pleasing, the vertical and rooftop greenery help to reduce the carbon footprint of the hospital, assist in at-source stormwater management, mitigate urban heat island effect, whilst at the same time also creating a therapeutic green and healing green environment for the patients and staff of the hospital and visitors to enjoy.
