In Singapore, more than five million people live in a space measuring 710 square kilometers. Nevertheless, according to the “Asian Green City Index,” it is the most environmentally friendly megacity in Asia — thanks not least to the Gardens by the Bay, a 101-hectare park in the financial district.Kaba has provided security infrastructure for the park, the offices and all the research facilities.

Bay South, which with 54 hectares is the largest portion of the Gardens by the Bay ( in Singapore, was formally opened on 29 June 2012. The garden park in the fashionable South Bay district is as big as 95 football pitches and was built on land drained by the city authorities 30 years ago. It is designed as a nature trail and an ecological leisure area.

Gardens by the Bay is an integral part of a strategy by the Singapore government that further transforms Singapore from a “Garden City” to a “City in a Garden,” in which the city is woven into a green and floral tapestry. This aims to raise the quality of life in Singapore with a more holistic and all-encompassing program that enhances greenery and flora in the city.

Kaba keeps everyone safe
Since the preview opening in April 2012, thousands of visitors from all over the world have had the opportunity to experience the Gardens by the Bay. The government of Singapore wanted a safe, efficient and effective solution for the four entrances to the enormous park – a system that would ensure visitors’ safety whilst not impeding the flow in and out. Kaba proposed a system involving a total of 14 sensor barriers and 5 half-height swing door turnstiles that fit in perfectly with the sleek architecture.

Barcode readers at the front of the HSB-E04 barriers check the validity of tickets when the visitors present it to the readers, which the gates would then automatically open to allow entry. The gates close behind each visitor as they pass through, thus disallowing the next person to enter without having their tickets validated first. However, the turnstile is equipped with safety features such as its ability to sense if a child is in the barrier zone. Four half-height turnstiles with swing doors HSD-L06 and one half-height turnstile HSD-E03 have also been installed for emergency usage, adhering to high safety standards the local authorities hold high importance of. The system is able to cope with high visitor numbers as seen in the preview opening and expected after its opening at Gardens by the Bay.

In addition, Kaba supplied 681 quattro pluS cylinders for doors located in the cool dry and cool mist arena. Kaba worked with CPG architect to formulate the best arrangement in combining all cylinders to be integrated under a master key plan.

Giant trees made of metal and concrete
Many Singaporeans visited Gardens by the Bay on opening day and marvelled at the incredible diversity of plant life to be found in Bay South, right in the middle of the financial district. The central features of the garden park are the 18 “supertrees.” These 25-to 50-meter metal and concrete giants stand in the Golden and Silver Gardens. They have been conceived as vertical gardens and arehome to manythousands of different plants, including orchids, ferns and bromeliads. Two of these supertrees are linked by a 128-meter-long bridge high up in the air. From here, visitors can enjoy a fantastic view over the blossoming oasis of Marina Bay.

Another attraction is the Flower Dome, one of two glasshouses in the gardens. Under the glass dome – as big as two football pitches and 45 meters high – a dry and mild Mediterranean climate is maintained for 24 hours a day, 365 days of the year. The constant 23 to 25 °C temperature provides an ideal habitat for plants from the Mediterranean region, including oleander, orchids, olive trees, date palms, dragon trees, cork oaks and cacti, but also baobabs from California, bottle trees from Australia and aloes from South Africa. The second glasshouse, right next door, provides a damp, tropical climate like that found in mountain regions 1,000 to 3,000 meters above sea level. Visitors travel by lift up to Cloud Mountain and then wander back down along a mountain track past a 35-meter-high waterfall.

Plants from all over the world
The Heritage Gardens show off Singapore’s great and varied cultural heritage. In this Chinese, Indian, colonial (i.e. British) and Malayan garden, visitors can enjoy a selection of trees, shrubs and spice plants from countries that have had, and continue to have, a strong influence on the Southeast Asian island and city state. There are bamboos, pagoda trees and junipers in the Chinese section, figs and jasmine trees in the Indian. In the Malayan garden, there are breadfruit trees and medicinal plants such as carambola and tongkat, while the colonial garden is host to cloves, coffee bushes, cocoa and rubber trees, nutmeg and oil palms. This green oasis in the middle of the urban jungle is completed by the Dragonfly Lake, ringed by a two-kilometer-long promenade and a series of pavilions. Large expanses of lawn invite visitors to relax, have a picnic or play.

The lake is not just a pleasant place for the five million or so inhabitants of Singapore to come and relax, but also serves as a natural water collection and treatment facility for the Gardens by the Bay. Dragonfly Lake collects all the run-off from the gardens. Its aquatic plants then purify the water before it is discharged into a reservoir and distributed again around the gardens. This creates a closed ecosystem designed to water the garden’s 163,000 plants. The Dragonfly Lake is also an aquatic biotope rich in species in general, the design and construction of the rest of the gardens are informed by sound ecological principles. The solar cells on the “supertrees” produce enough energy to light and cool the two glasshouses.
